I have a 120AX, which started life on an ESM FW190, and flew it quite respectably. I put a second one together and this time used an MLD28 gas engine, which also flew the plane well (better in fact, however the second one was lighter due to a built up wing).

The 120AX has now replaced a Magnum 120FS in a 65" Midwest Stearman, first time out Sunday seemed that it gave me the extra grunt I was looking for.

Without getting into the gas vs glow debate, my experience with the 120AX is good, so if you can get a fgood deal go for it!
