I have been fortunate enough to purchase a preproction fuselage and tail surface kit from RCplans and I have a detailed build thread going over on rcg, but thought I would like to share some of the pictures of its progress here also

I'd like to have as much of the internals working before I skin the fuselage. So I have decided, as there is a fuselage stiffener externally on the Lo100 that starts behind this point, I may as well make the tow points scale so I'm making a pair of these one for each side. With a nice grunty servo between them, then the bridle will also be on a loose loop so as long as one side releases, I'll be off tow. I envisage using bungee help for slope launches, so this should also allow a little climb on lift off. Next I'd like to get all three serrvos sorted for the tail surfaces, a pull pull with bellcrank for rudder and a pair of carbon pushrods for the elevators.

Tailplane

Tail end progress, today the leading edge and top of the fin bave been trimmed and sanded closer to their final shape and the tailplane is now all glued up as a frame work ready for the skin, ive put hard points into tbe mounting area, tbe front has a 20x10mm channel in tbe box and the rear mount is filled with laminted spruce as its a bit thinner.
Before i stopped for the afternoon i started setting up the .8 ply skins for the stab because tbe tail is longer tban tbe 4' sheets I trimmed tbe sheet to fit tbe second to last rib each side making the joins in tbe ply out near the end in the lower load area and also making the joins the same on each side and by cutting tbe cut off piece in half i can do the complete top side with minimum material waste

Mounted

Another small milestone this morning, tailplane mounted after leaving overnight to dry, after breakfast im hoping to glue down the tip skins and add the leading edge before i can start work on elevator horns and sheeting.

Glad you like it John Not scarfed on the tailplane as yhe only joins are so close to tbe tip and also at tbe point the spar starts tapering sharper, I do plan to scarfe the fuselage, do you have a jig or secret master zen tip to making the scarfe easier ?

See my turorial videos here for an easy way to make scarf joints. It also shows how to form ply around sharp radii.

Although it shows a wing, the method for the fuz is the same.Hope it helps.

This morning before work I was able to have ago at making a horn system that Im hoping I will be able to manage through a scale hatch in the side of the fuselage, the plan is that the aluminium squashed tube section which is a lovely snug fit around the modified dubro heavy duty pull pull systems nylon flag which I've drilled and cut shorter so now instead of being like a flag threaded onto that threaded bar its now more like a horn, once the horn is slid all the way into the aluminium tube then I have a single self tapping allen head screw that is the only part of the process that needs to be done through the hatch <, the pushrod attaches to the bottom via a bolt through solder on dubro clevis, this clevis will be soldered to a length of wire which will be epoxied inside the carbon tube pushrod,the tube will also be bound at its end with either carbon tows or thread so that it can't split along its grain

Ive had a busy couple weeks of things like work and family slowing down the process of the Lo100 but tonight I managed to get the elevators hinged and sheeted in Balsa so small steps but it is progress, Im using a removable pin with Robart giant hinge points,, I very carefully filled of the peened part of the rivet then opened out the hole just a smidge to allow the pin to slide smoothly with out being hard or sloppy, Ive used aluminium tube between each hinge point so that the sharpened pin guides itself through all parts of the hinge without too much bother. I used balsa scrap to support the tube and then I shaped this down to form the leading edge of the elevator.

Thanks John, yes I'm keeping the edge of the build in stands all lined up along the edge of my board until I flip it over to do the bottom and I'm planning to do as much of the bottom in single pieces from crutch line to crutch line in one piece which should help to prevent being able to built with any deviation.

Today saw the support stands getting cut off and the wing mounting blind nuts being installed followed by the fuselage being bolted down to the bench ready for the bottom skin to be made and applied, In the morning Im off to a buddies furniture factory to slice a couple strips of ply up to form the skid from, then in to town to get what I hope is the last batch of ply for the fuselage, all going well I'll have a lot of the fuselage skin by this time tomorrow night

Finally some progress on the wings, im assembling a kit of the ply skins all cut to shape first then ill finish all the spar slots and glue them in, once I have a wing i can man handle around in one piece ill be slicing the back of the foam of back to 6mm in front of the hinge line and facing this with 2 pieces of 6.5mm balsa then ill have good straight wings to start building aileron and flap onto the back off and because they are full skun control surfaces im going to build them straight onto the top of the bottom skin then i can sand the whole lot to profile before adding top ply skin, ill also chamfer the trailing edge bottom skin so that the top skin of 1.5mm will be the maximum thickness of the trailing edge

So, spars and joiner tubes are now in and done, not a very exciting picture so i wont bother with that,.a couple of my scale soaring buddies showed me a dash panel for what looks like it could be from.an Lo100 and it was full of ipad screens etc, and gave me a little bit of stick about my simple 4 dials so ive retaliated with what you see here, my plan is to make a dummy frame to go around this old samsung phone to make it look like the Garmin in te other picture, now tbe phone doesnt have an active sim so real time gps is out for now but i figure i can save a little video file to the phone so tbat it will appear to be working whilst im flying, (bring on the head cam in cockpit vodeos now i say)

Still battling for time, but I did spend a little time in the shed before work yesterday and now both wings have the 1.5mm sheeting chamfered back to accept the two layers of .6mm ply wrapped around the front, I need to get back to my ply supplier to pickup some more before I can continue with the leading edge, so if time permits today I'm going to start removing the flaps and ailerons and start work on hinging and setting up the drive for them.

AEB
Possibly not but the wing is skin in 1.5mm so there would be quite a void to then fill and it's .6 bass ply not birch which is definitely tougher. I did deliberate for quite a while and decided it would be easier to fair into the 1.5 with two layers. I'm really happy with the strength on the wings considering that there isn't a huge amount of spar inside.
The left wing has now had both its control surfaces cut off and beveled for hinging, hoping to get the right wing done tonight

Both wings now have flaps and Ailerons removed ready for hinging and pushrod set up,
Small change in plan, my original plan was to bottom hinge the flap and top hinge the aileron, well the flaps are still going with that plan but Im going to go back to giant Robart for the ailerons as Dumbass me forgot to take into account that because of the change in section in line with the plan form the hinge line is only straight at zero deflection, so my plan now is to make thin glass fairings for the hinge gap as I didn't forsee this problem, when I built in the structure of the ailerons and drag spar, :(
any way the plan is to now re-bevel the aileron leading edge ready for the hinge points then fill the gap temporarily with balsa, then use Packing tape up to the hinge line before laying a thin layer of glass and resin over the area that I can trim back after cured.
(hope that makes sense)

Not sure I understand the question? My fuselage is the first cut from Andy and Shane, and the wings are of my own design as the wing drawings weren't done at the time my fuselage was cut I believe the wing drawings for the kit are closer now.

First leading edge out of the press, very happy, with the result, both wings have full leading edges, they have been sanded down to fare into the rest of the sheeting and currently have a smear of filler over the join just to try and keep the section as true as possible, now the fun of fitting servos and hinging begins for the wings

Both wings now have leading edges and all moving surfaces removed from them. Tonight I've managed to do the dry fit of aileron hinges to one wing and have fitted the false leading edge to that aileron ready to be shaped in the morning, before work. Pictures to come after that. I'm hoping to get the other wing to the same state tomorrow so that I can start making wing servo mountings and the wiring loom for each wing. I won't be making and shaping the tips until I'm closer to having the wings ready to cover because as they are at the moment, I cannot move them around in the workshop holding them vertically. With the tips on they don't fit between floor and ceiling.

Quick video of the trailing edge bits showing 0.6mm bass ply that I inlaid with a dremel router so that I should only need minor smoothing in front, I will be glassing the inside and whilst that cures I'll hold the surfaces at a mild down position so that the wiper has a positive seal at neutral.

Do be careful with the flap horn geometry to get a strong positive linkage with the flaps deployed. the horns will have to be set well back from the hinge line.

Ok I'm usually pretty good with this geometry but my plan was to run the pushrod to the top of the flap just under the wiper and keep all drive internal as the full size is driven with torque tubes back to the centre of the pylon, feel I'm missing something now ? Please explain further JG

Hi Alexis
No problem with an internal linkage but do make sure that the horn extends forward of the hinge line to allow the pushrod to connect as far forward as possible. In this way, when the flaps deploy the mechanical advantage of the geometry will increase as the flaps lower so giving more effective power to the linkage.
It needs to be the opposite if using an underside horn and linkage. In this case the horn needs to be set back behind the hinge line to get the same effect.

The servo holes are cut into the foam with a hole saw, then I drop in the strip of 1.5mm ply and press down the ply flange, all glued up until I get home from work tonight. Then I will epoxy in the mounting blocks for the cover and remove the foam from inside the hole and mount the servos to the hatches..

Things are moving along slowly but moving on they are.

Anyhow here's what I have so far, including how I went about making hollow balsa wingtips, nothing earth shattering but perhaps a different method to carving from solid.

The final pre aint jobs continue, last night I started running all the wiring through and did the final set up of elevaor drives, I've made brass tube inserts for the connection between the pushrods end and elevator horns so now when I assemble the tail I can drop the new brass tube horn ends into the aluminialuminium pushrod ends and secure with a screw through both, I also rebuilt the rudder drive with a double ball on the idler bellcrank which has removed all slop and improved the geometry of that somewhat, the rear of the fuselage is now all programmed and working I have had the wings all working but will be doing another final hook up and test of flaps and ailerons before paint now that the hinging is all permanently attached, I've settled on ,in the cavity under the wing as the perfect spot for the receiver so the extension leads all are set up to go up to there including doubled up power wiring from the Front mounted battery tray.

Always good to see you down under John, I'm hoping it will be ready for the SSL Milang aerotow at the end of may, it's very close to flyable now so should make it

Under 23kg is looking like the current estimation based on prepaint weights

Well my pilot was printed from a file that is definitely Patrick Stuart, but obviously my painting has altered him a little and so many have commented that he looks like Walter White? As a fan of the show, I couldn't resist helping that idea along and last night I needed a diversion from painting, and so set to after work with needle and thread and a piece of felt fabric and here's the result.

Today was a big day, first complete assemble and test of all functions, very minor issue with the bolts that retain the rear half of the fuselage but other than that I fairly happy

Looks good Alexis, but there is a crack half way down the Fuz....

Now you have to fly it. Hand launch first, I guess.

Now hand launching this would be a job for Swarzeneger I'd say

She flies, I'm over the moon, crisp response to all flight controls, cog seems very close only a couple clicks of aileron trim, I'll make a video once I have something to work with, here's a couple pictures of the big day for now. Little side note , it all fits in a vw polo

Great stuff Alexis. I love the working joystick from the internal view.

It looks like it flies rather quickly - was that deliberate or it's natural speed?

Congrats

Thanks, The stick and pilot animation are still works in progress but im happy so far, as for the speed, it will need more testing of the stall behavior before I'll go to the slower end of the envelope, certainly at no point even a couple points during the tow that looked very slow from the ground did control authority feel like it was mushy so I guess the trim at the moment is a little quick but its safe for now, remembering that this is an aerobatic glider that will need to maintain momentum to fly a good routine.
Regards,
Alexis
