RE: CMP giant scale Zero build
Everything fits fine. The finish is worth the price of the kit. The fiberglass fuselage is really nice and all the paint matches.
I have no other experience with "higher priced" warbirds, but you get what you pay for, in most cases.
This plane comes with 1/4" wire gear, but it's not real music wire.
I agree that retracts would cost more than the plane.
The CMPro ZEKE is well worth the price, if you disregard the total lack of any written instructions.
