RE: strip aileron flutter avoidance
That is accurate..... 10x6 is about the largest prop you want to run on the engine ---
some folks have played around with 11x5 props, but that is really pushing it... and its not recommended.
Keep in mind the Banshee would be considered a "46" size plane in todays design world. It is not that big.
The 60LX is essentially a .46 size engine with big numbers.
