Redline 1.00 engine heli

Just bought a RED LINE 1.00 Helicopter Engine will this engine fit in my trex 600? I did not check this before a bought this engine anyone know this answer

Unfortunately, the answer is no. As you will see when you get the engine, it is substantially larger than a 50 or 55.

It’s too large on all accounts. The crank shaft threads are 5/16 on the 100 and 1/4 on "50" size motor. The issue then falls into attaching the clutch. It’s also likely the head of the motor would get into the forward area of the main frames, landing gear and what not.

It really needs a 50 size engine.
