Title: Scratch built Learjet for RCI Sweepstakes 2014
Post by: topalle on April 27, 2014, 10:50:42 AM
I am building a Learjet right now for the Sweepstakes.

Bottom part of wing done with coro. Given enough support. Top part wil probably be made of foam board.
So will the fuselage be

For pictures, I don't know when power will come back.I'll post as soon as power is back.

Technical Specs.
Wingspan 36"
Wing material coro, foamboard

The Scale factor is  
1:14.5

Wingspan is 91.44 cm
Length of fuse required is about 122 cm

The weight of complete wing at present is 200 grams. Aimed weight of fuselage to be at 250 grams with all mixture of materials.

Tail weight to be a max 100 grams

Total empty weight target 550 grams.
AUW target 800-900 grams...

What should be the ideal size of edfs for this model?

How to respond. You are creating a hangar full of incomplete models :(

Complete to the point of maiden, else none are eligible for the sweepstakes

Yes, the models seem innovatively put together, but the proof of the pudding, as the sage said, is in the eating

If it is because you don't have electronics yet, that is really unfortunate. Most of your builds seem airworthy

I am borrowing some elctronics from fellow modellers. By the end of may, as my paernts promised, I must be able to get two models airborne..

Winglets are unnecessary for a model of this size. If, however, the purpose is to keep a scale look, you could extend the spar by a tiny bit and then stick an externally cut winglet with a slot in between so that you can attach it to the spar.

I do not believe this is the same plane as in the other discussion
