I have a gp cap 232 with a saito .91 its totalweight with out fuel is 6.4 pounds. It is an awsome flier, blenders, knife edge spins, torque rolls, elevators are no problem. I got a 14x6 apc that swings around 9400 rpm. The saito 100 will be a better choice for
this one but the 91 can hadle it very well.
