Prop is useless at these speeds anyways.

What I"m looking for is ideas to beef this plane up and reduce the likely hood of flutter.

I'm going to need a battery for 5 hours. I'm thinking a 5000mah 3 cell to be safe, but I could go a little less.

I'm thinking fiberglass the whole plane, carbon fiber the ailerons, metal servo arms, 4-40 pushrods all with sullivan clevises and pushrod connectors.

Love to hear ideas
although that would make for a sweet video . i hate to be a buzzkill but . dont you thik thats a lil dangerous . if you lose signal that ship is just going to be a like a giant 3 pound dart racing down the sky . the damage or injury that ship may cause will be alot. have you taken into that into account .
