These actuators typically were used in planes with engines under .29 cu. in. and for that size engine they should be fairly sloy flyers. The ideal engine size works out to be somewhere between .074 and .21. You saw many plane designed for Ghost in the .15 to .19 cu. in. range. An Andrews H-Ray, GiGi, Mambo, Rodent. Whiz-Kid, CG Skylane, Lil Tri-squire, Esquire, Headmaster are all good galloping ghost ships.
