Has anyone ever had this engine and how does it Run?

Hi!
If it is made after ...let say 1985 it is not so bad. The first TT engines releast in the late seventies were very bad.
This engine of yours has the power of an OS LA or FP .15.
Put on a 8x5 APC prop and enjoy!

not very bad but just of ancient design, the old .15 had a baffled iron piston. not real powerful but ran just fine.

I've had several TT GP .15's. They are a real nice bushed sport engine. I had a little trouble with some about four years ago with them having a loose crank/case fit when new. The one I have now is excellent! Like jaka said...put an APC 8x5 on it, load it up with some 10% nitro fuel and an OS #8 glowplug and have a blast. Mine spins an APC 8x5 @ 14K with 10% and the #8 plug.

Actuallywith the exception of the head and case [4bolt vs 6] the TT 15 is a direct clone of the OS15P. A good source of parts if you want to keep that FP running. To be honest though the TT is better made then the FP and actually holds up a litle better.
