Got a Saito 30 in my Lazy Tiger. Nice flyer, loops from level flight, & resonable speed with 11x5 MAS prop, on 15% nitro. Beautiful sound!!!! Unfortunately, very limited verticle; a Saito 40 would probably be a better choice. Only about 1&1/2 oz more weight, & a load more power. ...... Bought a Combat Mustang to put another Saito .30 in, but looks like the rocker arm covers will be hanging out below the cowl. With no landing gear, I'm hessitant. ........ George K.
