Large Model Association Forum

this is my new project

new petrol motor and tank

an she will be in the air

If i said fly it with aileron differential, would you know what i mean? Nice moth, cant go wrong with a Tiggy, stick and rudder teacher, nice!

aileron differential, would you know what i mean? = no

brought last year intent on referb and clean up and bring to a show or two for some one else rto trim and set up

no sure i should go for a 2 stroke or a 4 stoke petrol with pitts

Hi Richard, a 38cc NGH Fourstroke petrol would suit.

Set it up with the the down going aileron moving half as much as the upgoing, this basically stops the wing getting into a stall situation, and getting aileron reversal, ie, the downgoing ailwron creates drag, rather than lifting the wing, it stalls it, and the wing drops, quite common on things like moths, cubs etc, I once asked a friend if he was ok for the testflight of his plan built 1/4 moth, he said he had to do it sometime! He had got the differential the wrong way round, one tranny thrust into my hands later, and flying behind the pits, i got it down, only to get a bollocking for flying behind the pits, i erm, put them right lol!

thats the one i had in mind but the do a 30cc version was not sure that the 38 would be a bit much


original was 26 cc laser 150 glow

Richard, Aileron differental means that the down going aileron is set with much less movement than the up going one.
The reason this is necessary more so on some models than others is that the down going aileron creates more drag
than the up going one and will pull the aircraft toward the side of the down going aileron. This can be held with rudder
but if you have the correct aileron differential no correction is necessary.
Anything to make our life easier eh. Good luck with the model and never take anything for granted.

thanks tony i think i get it once

but i will play safe and get one of u chaps to help me out

Don't forget, Bipes are very draggy.
So if the engine stops, don't think it will float on to come into land. At some point the thing will just stop! If you do find the motor has stopped, nose down get some speed up then you can turn her where you need to go.

Lovely to fly though...I love flying my Bipes. Enjoy!

thanks pete

Dave in our club has a Precedent Stampe with the 38 in and it flys great

Both my Stampes have an Evo 33gx....ummmmmm

update

paint has arrived for cowling respray the original glow fuel has destroy the paint
