Scale Soaring UK

Well you have to be ready!!!

Okay, since Barry’s obviously bored and wants something to read:
Upscaled Keil Kraft Spectre, intended for towing duties.

superb build thread Trevor with a very different slant on kit verses scratch build. cant wait to see the next episode.

Wow, never thought of that! Well done.
Brian.

To add to the melting pot here's my Chris Williams 1/5 scale Minimoa getting its first balance check today.

Not sure if it is going to fly in 21 or 22 - depends on how long the last 20% takes and what else gets in the way. There's also the challenge of deciding on a colour scheme.

When it is ready I will no doubt be looking for a tow!
Bill

Looking good Bill. Tug ready and waiting.

Well I'll be building a chris williams 167" 4.4m Scheibe-Loravia Topaz

I’ve had the Alsema Sagitta on my build list for a long time now and this winter it’s time has come. A few years ago I downloaded Jilles plans for his 1:3.5 version and even wrote out a parts list but I now feel that it is a bit too big for my aging frame to carry up a hill.

Vic Steel did a 1:4 version a few years back and that is easier to handle so a set of plans has been purchased. Vic’s version uses foam wings but I felt the need to design a fully built-up wing which will be nearer to scale. I also found a few problems with Vic’s fuselage structure, the least of which has the wing sitting at 0 deg to the fuselage and the tailplane sitting at +1.5 degrees. I have therefore had to do a bit of re-design in the fuselage department.

All the materials have been purchased from Balsa Cabin and I have started prepping formers and wing ribs so sticking bits together should begin fairly soon. I hope to have it finished for events this summer.
I have added a couple of images of the prototype in intend to model.

Hi Guys,
Question...
Would this model, the Schweizer 1-30, be good enough to be a motor glider?
Schweizer did use the wings of their glider, the single seater 1-26 as well as the elevator and the rudder.
The fuselage was build new, with the engine and cowl of a Piper Cub J3 and the landing gear of the Cessna 170.
They kept the airbrakes in the wing too.
Schweizer did however tow gliders with the 1-30.
See the book of Paul A Schweizer and Martin Simons “ Sailplanes by Schweizer, a history “.
I did find a note that says motor glider, but the look is different only when you look down on the plane and see the larger wing span...
In 2014 I build this model as a fast in between model, but sold it the moment the paint was dry... only 3.2 m span.
Now I designed it in 1/3 scale with 4.06 m span and with the possibility to tow with it..., and started building.
And yes I know, it has been build on the other side of the globe too!!!
If not good enough, you let me know...
Noël

I hope you flew it before you sold it Noel!

How big a mortgage did that take, Brian...?

Hi Brian,
and no I didn't... and it hasn't flown yet...
But that will change when my bigger one is ready, I hope...

Another month has gone by on my scratch tug build, based on the Keil Kraft Spectre control line model of the 1950s. Latest diary entry is here.

Chris, yes it was arm and a leg time.
It appears that the price of timber has almost doubled. The rumour in the trade is that a certain Mr Williams is entirely responsible for the world shortage. Calls of "not another Minimoa please" can be heard from around the country.

Too flippin' late...!

Chris, how's the 1:4.5 Sperber Jnr coming on? Such a striking shape...

The Junior's alive and kicking and is a few video clips short of a movie...

Beautiful - you've been keeping this one 'under the radar'!
Is there gonna be a plan and short kit...?

Well a plan, certainly...

Hello all,
Late to the party, but I've just finished a 'Micro Wolf'. Modified a bit - I've tried to match the reproduction I saw at the VGC rally in Bourges (France) in 1988. Not sure why, but it had a different rudder shape at that time, but I've since seen photos with the rudder changed to the same as Chris's design. However I wanted to be different, so stuck to my interpretation of the photo. Also this version has the later aileron shape, plus airbrakes and the slotted outer wings. I drew the line at slots and airbrakes, after wasting ages trying to make 1/7th scale top & bottom brakes that worked reliably!
Changed the elevator to a stripwood construction as an idea to use with transluscent covering. Used Hobbyking matt film and oralight scale white on fuz. I uses Ronseal satin oak on the balsa before the clear film and I think it has helped reduce the whiteness of bare balsa. First flight today went OK, although I broke the skid on landing. Photos of full size and model below, I hope! (first time posting images)

Funnily enough, Dave, I was flying my Wolf on Oxo this afternoon...what a small world!
