I`m new to nitro planes,and recently purchased a japanese zero plane used/no engine.Is there a formula for figuring out what size engine i need?Do you go by wingspan or the weight?Thanks in advance.

What's the wingspan?

Close to 52",and maybe i`m used to foam planes,but it feels heavy.Thanks Rolex

A .60 2 stroke or a .52 4 stroke. The 4 stroke will give you more torque and allow a bigger prop, plus it gives the sound of the real thing.
