Which servo arms are good (don't need the best) and what length should I get for 3d throws (building extra 300 lx). I plan on using the hitec 5645's on surfaces (5955 on Rudder).

Will the hitec supplied arm be long enough (aluminum)?

Are the dubro's new line any good?

Do Futaba aluminium arms fit on Hitecs ?

If anyone could clarify this confusing topic for me

Thanks
