Hello,
I have started the build of the Ikarus Meteor scale 1/3 designed by Jilles Smits.
I will post my progress and pictures, will let you know the things I changed and hopefully you can answer some of my questions.
First of all; what a beautiful kit this is! Drawings are a piece of art, wood is selected on the function it serves and all fits perfectly. My compliments to Jillis for this 3d Puzzle!.
I have started with the fuselage. Put the formers on the building board along a straight line and try fit everything before glueing (first with 10 seconds glue). Be aware; certain pieces only fit when assembled in the right order! And some formers are not mirror symmetric as I found out too late. :o

Nice to see more Ikarus build activities!
I promised to report the (little) changes I decided to do.Nothing special because all is very well thought through.
The first change I did was to the canopy frame. I made the top a little less wide such to create a bit more scale appearance.
The second change is the removal of the servo tray on the fuselage floor. I will move the servos for rudder and retract more to the aft. I have not yet decided where but that will be figured out later. Anyway, this change will give a bit more room to the pilot.
One last picture added with the progress sofar.

Wednesday is the day for doing some work on the Meteor! I finally ended up at the tail. I did not yet glue the parts together because I want to double check the fit and alignment. I consider to create a template for the tail to secure it is glued in vertical position.

I have a question. Maybe the other Meteor builders or Jillis can help. Its about the end rib of the rudder. How can that rib fit into the slots of the leading edge of that rudder?

I am in New Zealand ans cannot access my file. I am sure rib ER8 should have a square hole and round hole in the tail end that I do not see. The square hole should take care of the notches in the spar. The ribs to be split over the square hole so it can be fitted to the spar.

Cheers

Jilles

Thanks Jillis and Cliff for your quick reply and support. The rib is not like in the pdf as it is missing the square hole. But no big deal. I did a small modification and cut the rib in two pieces and added a slot. Hope the picture clarifies!

I have received a Fema retract for the Meteor.
Really a nice piece of gear! I will mount it kind of reverse such that the wheel swings up in forward direction just like the real one. Suppose this will not impact on the retraction. There is anyway plenty room for it.

Today I prepared the rudders for the covering with 0,4 mm ply. First some balsa filling is to be applied to leading and trailing edge. A bit of a time consuming job.
I decided to apply a tube and wire hinge for the rudder. This to allow for the option to disassemble the rudders when needed.

Hi, I'm building the one on the other forum, very happy to answer Meteor queries here. There are a few things that will make you stop and scratch your head, but there will be one or more solutions out there to get you going again. Apart from the sheeting on one wing the structure on my build is complete.

Hi Brian,
I am following you on the rcgroups forum and read all your good advices with great interest. This has a big value for the building of the Meteor! See my post #182, that is me!

Now covering the rudders with 0,4 mm ply. Thats working fine when pressing with some blocks But this method will for sure not work anymore when dealing with bigger curvatures like around the fin post. So I have tried the ironing method. And indeed, it works perfect! After cooling down the pieces are fixed!

I had a small issue with the rudder. I wrongly assumed that I could glue the ply surfaces while putting the rudder on its side on a flat building board. Luckily I inspected the rudder after around 30 minutes when the gue was not fully cured. It was clearly visible that I had a twist in the rudder! So tried to over correct it into right shape. This happened to be quite succesfull. I am happy with the endresult.

Glad you got it sorted.
I looked in my build thread, I didn't mention it, did show it clamped together off a bench, as I had noted what you discovered.
Feel free to PM me if you get stuck, you may find some head scratching moments are coming up.

I have now started with the 0,4 mm ply panels on the tail section. I do not have experience with it but with some patience it works quite fine. It requires some own initiative to get extra support for the ply panels. I have added soft balsa in variuos places and created a support rib for the stabiliser shoulders.

Re: Ikarus Meteor 1/3

Posted: 14 Dec 2019, 21:38
by Dopieman1
In previous post you can see that I already glued the pipes for the stabilisers into the fuselage. Afterwards I realised that this could create a possible misalignment with the pipes in the stabiliser. Better to glue everything together! But after testfitting the stabiliser I concluded that the worries were unnecessary. Most likely due to high accuracy of the laser parts :?

I have little experience with ply sheeting using the iron method. But first pieces, with rather strong curveture went quite ok. But still I would prefer covering with balsa. Looking forward to balsa sheeting of the fuselage with lots of double curvatures! :D

Wow she is coming along beautifully.

Apologies for being off the radar its been a terribly busy end to the year. A new year is here now and my resolution is to finish up this build and get started on the Horten from Jilles.

Anyway I am almost up to where you are and then we can build together , two heads are better than one :)

Happy New Year

Hello Steve,
I know these busy times. Frustrating when you can’t spent the time to your project. Anyway, I had a rather productive day. Now started with planking of the fuselage. I love that work! :D

Posted: 19 Jan 2020, 16:32

A bit of progress today with the wing. I have aligned the wingjoiner pipe with the root rib on the fuse. In this way I hope to avoid nasty gaps between wing and fuse.
Then started with cutting the spruce sticks for the nose and main spars. I use 2 pieces 6x6 mm for main spar and 10x2 mm for the nose. Here I deviate from the plan because that is advising ply. For cutting the joint I use a proxxon sanding machine. It has a guidance support what can be set to a specific angle. Works like a charm!!
The construction of the wing requires to put all pieces together and only than you can glue it. Its a bit tricky to get it all together but it will save you from errors. Use CA for glueing it all together.

Hi Daniel,
Not sure what you mean but on one of the pictures in my previuos post you can see that the wing root fillets on the fuselage are covered with ply. The fuselage on that location has strong curvatures in all directions. That section will be covered with 3 mm balsa. because of the curvature I will sheet it with strips of around 8 mm wide. Its a bit of a puzzle but nice work. I will post more pictures when I come to that part!

Did today some sheeting of the fuse near the cockpit and wing root. Strong curvatures require some fitting!

In the mean time I did some work on the wing. I glued all the ribs in place. That requires quite some fitting and alignment before everything is in right position. Then just some drops CA will do the trick.

Re: Ikarus Meteor 1/3

Posted: 16 Feb 2020, 08:12
by Dopieman1
And almost forgot to report; I changed the leading edge support from 1,5 ply to 2 x 10 mm spruce. Required only a little bit of reaming.

Re: Ikarus Meteor 1/3

Posted: 16 Feb 2020, 21:07
by Dopieman1
Lessons learned from Bananaman (see rcgroups) ; there is risk of bending at the tip of the wing. For that reason I have added extra supports to every rib. The balsa supports on the leading edge measure 24 mm. These supports will hold the weights on the wing when it is sheeted.

The main spar is getting into shape. I like this design. Its like a tree, strong at the base and getting slimmer to the top..

I have now finished the sheeting of the top side of the fuse. Next is to cut the supports such that I can turn it around for the bottom half. But before closing the bottom side I need to install the retract for the skate and servo's for the rudder and main gear. Most is well prepared already but I decided to move the rudder servo aft of the pilot. That will ask for some clever solution... :?

Some progress on the wing. All top stringers are in place. The balsa fill-in for the leading edge is also done. Ready to do some sheeting!

Switching between wing and fuse all the time..I have cut the fuse supports and now I can start the work on the bottom side.
First the bottom side of the wing shoulders. To support the ply sheet, some extra balsa is added.

Re: Ikarus Meteor 1/3

Posted: 27 Feb 2020, 09:02
by Dopieman1
I have a question; I noticed that the ply sheets suffer from some bubbling due to swelling. (not sure I use the correct wording.. :? ) This is caused by the high humidity in my hobby shed as I am not heating it all the time. When I heat the surface the ply flattens again. Now I might not need to worry so much as all the ply surfaces will get covered with epoxy resin, but the inside will not. So I suppose that humid conditions will continue to cause some problems. Therefore my question; do you have similar experience and any advice to avoid this problem?

Re: Ikarus Meteor 1/3

Posted: 05 Mar 2020, 21:16
by Dopieman1
I have started the sheeting of the first wing panel. I take it piece by piece. This to get some control and to not run out of clamps.

Re: Ikarus Meteor 1/3

Posted: 13 Mar 2020, 19:02

Some more activities on the wing. I have sanded the support blocks in the nose section. That went rather easy as I used soft balsa. Just sand until the black has disappeared from the the ribs.

Re: Ikarus Meteor 1/3

Posted: 13 Mar 2020, 19:06
by Dopieman1
Then the sheeting of the nose section. I bought a rather hard quality 2mm balsa so the bending will take quite some force. Too overcome that problem I wetted the top surface a bit. The sheet will start to curve by itself and can be glued with almost no force applied.

Hi again,

Its been a while since I checked in due to such a crazy year. I am moving soon and once re-located I will have a large shed and workshop I can really get building.

Your Ikarus is looking fantastic and hopefully mine will meet the cut as well.

Have a great day

We seem to be the three individuals building it at the moment. I was making great headway, but many things have occurred recently, work got very complex, my career has ended courtesy of Covid and I am having major surgery in a week that will slow me down more and keep me from some workshop activities. Hope to get back to it ASAP.

The Meteor assembled near the front.

There is still no progress on my Meteor. I decided to first finish a Caudron C460 1/3 what I started some 10 years ago. But that job is almost finished and then back to the lovely Meteor!

I have started the build of the Ikarus Meteor again. Weather was terrible so no excuses anymore! There is some work left in planking the left wing and even a repair is needed as the cat was a bit too heavy for a 2 mm balsa skin..
Jilles has provided me with a new design for the flap and aileron ribs. I did not want to follow the original design which showed full balsa construction. Now I can extend the balsa skin of the wing and build the flaps and ailerons in"situ". I will post pictures!

Time to cut the wing in two pieces and remove it from the board!! A milestone achieved! ;)

The wingpanels are still quite flexible in torsional direction. So a support is needed to keep the wing straight when skinning the bottom. Constructing the correct wing incidence from the drawing is a bit tricky. There are only a few wing sections on the drawing. The other support points are constructed by creating a graph to check the alignment of the wing incidence over the lenght of the wing. The results seems to be quite plausible. The wing root has an incident of 1,55 degreed and the tip has an incident of 0,7 degrees.

A sketch to clarify the modified flap and aileron construction. The flaps will be cut loose from the wing only when the entire wing is covered with glass and sanded. After the removal of the flaps, a balsa nose will be added to the flap. Hope this will result in straight and flush flaps!

Small update; the work on the inner panel is ongoing. Flaps are ready. Balsa hinge points added. Now adding the stringers and main spar. Stil quite a to-do list before the wing can be closed with the lower skin.

The mid panel is basically ready for closing with the bottom-skin. All webbings applied, I have increased the webbing plates from 1,5 mm to 3 mm at the critical locations (at the end of the wing joiner tube and 2 webspaces forward. Servo's fitted and wires applied.
But before doing this irreversal step some thoughts:
- should I add wing locking device to hold it to the fuselage? The plan does not provide details. I do have good experience with tape, but this baby is a bit larger.. The wing root area is difficult to access for a wing locking from the cockpit.
- the design shows single web plates except for the highly loaded areas. I like stiff wings so should I apply double webbing?
- I ordered the Schambeck brakes but did not receive them. Shall I wait to check if they fit? The plan is actually prepared for taking these type of brakes.
Any feedback is welcome! I need to decide in the coming days as Christmas holidays are coming.

Hi, I suggest that you definitely need some form of wing retainer, rather than rely on tape.
I have fitted Multiplex Unilocs to 1/4 scale models, but have found that they can pop out unintentionally with bigger wingspan models.
I’m not sure how easy it may be to fit given where you seem to be with your build, but I have found that the simple thin aluminium plates shown below seem to work well. They provide enough clamping resistance for normal use, but will pull off in the event of a major force.

Aluminium tab

Fixing plate/bolt
Fixing plate/bolt

These pics are from a 1/3 scale Olympia where the tab was fitted to the wing root rib & access to the fuselage fixing was easy.
I’m currently using a similar arrangement on a 1/3 scale Jaskolka, where a bolting plate has been installed inside the fuselage wing root stub & the clamping bolt will be inserted from underneath.
Another alternative is to have a plate in the wing & the tab protruding from the fuselage, inserting the bolt from under the wing root.

I would wait to try your brakes when they arrive as I am a firm believer that ‘if something can go wrong, then it will happen sometime” ;)

Another possible method is a a strong elastic band or spring going through the fuselage, connecting together hooks on each wing root.

Hope the above helps.

Hi Peter, I like that wing fixing idea. Getting access to tighten it is the key.

Here are a few unpublished photos of the Meteor from the event at Örebro 1950

Hi, this is not the Ikarus Meteor but the Cijan Obad Orao. Same designers as the later Meteor and quite similar fuselage. By the way, what a beautiful plane this is!!

I have fitted Multiplex Unilocs to 1/4 scale models, but have found that they can pop out unintentionally with bigger wingspan models.
I’m not sure how easy it may be to fit given where you seem to be with your build, but I have found that the simple thin aluminium plates shown below seem to work well. They provide enough clamping resistance for normal use, but will pull off in the event of a major force.

These pics are from a 1/3 scale Olympia where the tab was fitted to the wing root rib & access to the fuselage fixing was easy.
I’m currently using a similar arrangement on a 1/3 scale Jaskolka, where a bolting plate has been installed inside the fuselage wing root stub & the clamping bolt will be inserted from underneath.
Another alternative is to have a plate in the wing & the tab protruding from the fuselage, inserting the bolt from under the wing root.

Hello Peter,
Many thanks for your good suggestions for wing fixing. It gave me some good ideas! Not yet decided but I consider to copy the method where a metal plate is protruding into the fuselage where it gets locked with a bolt. I can still access that location. Pictures will come when its done.

There is a plan for the Cijan Obad Orao at 1/4 scale drawn by Jim Owen in the plans section.

Cliff, I wait for a 1/3 CNC kit of this beauty! 8-)

If you do use the suggested tongue & clamp wing retention method, you my be interested in the tip Jilles gave me about providing a “washer” which couldn’t be lost in the grass.
Epoxy a captive nut (with spikes removed) to your retention bolt ;)

Very good idea! But I would like to keep the hole in the bottom of the wing shroud as small as possible. So maybe glue the captive nut on a bracket under the wing tongue. Wings would be fastened by just turning in the bolt..Or do I miss something?

Hi,
You need a captive nut or similar as normal on your bracket (which is behind your wing tongue) in order to screw your bolt into & clamp the tongue between bolt head & bracket).
Normally you would put a washer under the bolt head to provide a bigger clamping area onto the tongue.
These (thin) washers often fall off when rigging the model & get lost in the grass.
The modified captive nut screwed onto the bolt is just one way of fixing a “washer” disc to the bolt so that it cannot fall off. Another way is to use a flange headed bolt, or maybe try to epoxy a washer to the underside of the bolt head.

Your Icarus is looking fantastic, like you my build has been stagnant for some time. Now that our move and generally our lives have finally settled I can now get back into building.

You are definitely well ahead of me for the time being. I look forward to more posts.

Steve

Hello Steve,
Hope you catch up again soonest! Its a lovely plane to build and brings a lot of satisfaction! Unfortunately I was a bit distracted lately with the build of a f5j plane. But more to come for sure!
