Quantum II 55 Brushless Motor what size propeller does it take thanks BOB
Asked by Bob Binly on 7th September 2017

That depends on your plane and setup... However a 12 x 8 is usually the sweet spot on these.

RE WOT balsa ARTF cg .How do I set the plane up, with or without the battery in place? Thanks best wishes JH.
Asked by John Hampson on 18th June 2018

You would usually setup the CG with all equipment in place

Part no M-Q2-55 brushless motor. Is it really an 8 mm dia prop shaft? Seem very big.
Asked by Richard on 19th December 2019

Has to be really - 6mm would be too small for this sized motor – you’re looking at loading a 14 , 15 or 16 sized prop on one of these and any smaller diameter could give whipping on a large sized prop .
