well, just as I sang praises for the plane, I need to give warning for the engine. I know some have had good success, but mine just broke. Was breaking in a new glow plug on the porch while ago, and the rod broke--right where it connects to the crankshaft. I'll send it back and see how good their customer support is--I'm not expecting much. I'll probably go and buy an evolution in the mean time, and maybe sell the VMAX if they replace it.
