Hi

I've a 30-size fun fly plane installed with an 40-size glow engine of about 1.5kg overall weight.

Currently, I use 10x6 propeller. I find it difficult to hover as if the power is lacking. Vertical climb is only possible if I were to speed a long straight line before the climb.

Does the propeller selection affect this aerobatic capabilities? What type of propeller is suitable?

Thanks for any help or tips.
