RE: Need help choosing an engine
Hi!
I have several of those "Junk" ASP .40 (or Kyosho .40 GX , same engine) and they sure out performs the OS FX.40 in any way in pylon racing!
Durable, Powerful and well made. Turns a 10x6 RAM or Graupner Cam-prop at around 14600rpm on 80/20 fuel! The TT .40 turns the same prop at around 14800rpm. One head shim removed and Nova-Rossi 4 glow plug used. Rear bearing (28x15x7mm) replaced with Swiss WIB C4 bearing from Dave Shadel.
