Hello all,
I will start today building the GP ULTIMATE.
I need some help in choosing a motor because I am very confused with the engine choises of other builders.
Some are using .46 to .90 2 stroke. Others .65 to .91 4 stroke.
One thing is for sure. The plane will be a little bit heavy even without the engine.
I love 4 stroke engines but they are heavier and I am not sure if the are going to fit in the cowl.
As far as for 2 strokes I stopped using them for some years now but have no problem trying them again.
Suggestions are welcomed.
Besides that I need some info and maybe some pics on how to use dual ailerons.
Please help.
Thanos.
