I got two foamie Muzzies from the same place, Pete and same maker. FMS? One is Red (Century UK) and the other is the Gunfighter version.(FMS). Taking off needs decent ground speed at least, landing not a an issue except for the crap retracts. Plastic swivel pins!
Replaced mine with E-Flites. See my article on the Dago Red Mustang. CG is a bit touchy too. Had to ignore the manual recomms and work it out myself.
