I’ve just got a Hype 3d with a Rossi 53 engine. Unfortunately I didn’t look at this forum and see the Rossi is not the best for 3d.

Can anyone recommend the best prop for this engine/plane.

Would changing the engine for a Weston UK T1 make a big difference?

I really like 4-strokes (although never own one) and was thinking of an ASP 91 its 200 grams more than the Rossi. Would this make a big difference, I have saved about 50 grams using light servos.

If I need to change the engine I would like to use a 4-stroke as seem good at turning large props with lots of torque and sound very good.

Any ideas would be much appreciated
