I am looking to build the dd. My last whiplash ended up in many pieces.

I unsuccessfully tried a smaller and higher pitched prop with the over sized 91 ys sr 2 stroke. The whiplash was heavy, add in the extra fuel, added c/f, and engine and it was over 5 lbs. Very similar to dd airfoil.

This time I am not really worried about max speed, afraid of a heavy plane I was thinking the 35 ax at 10 oz w/o pipe and 1.3 hp might be a good combo?

But is that enough for good speed and an easy launch???

Jett is just too expensive for me. But the webra 50 is also a light engine at 12 oz again I would need 2-3 oz more fuel so the weight is adding up.
