I would be interested. Under gas engines just start a new thread. Maybe title "UMS new radial Engines". I have the new Gas 55cc, 100cc 5 cylinder and the new glow 35 cc 7 cylinder engines. The 100 cc is a near perfect engine when using the APS power fuel pump. The 55 cc 5 cylinder had a lousy carb. The Saito 90R3 carb worked way better on gas.. -Tom
