OS .25FP??
I've read on here that you can put a FP.40 carb on the .25. How much does that improve performance? The FP series I'm told is a good sport engine not so much performance?

RE: OS .25FP??
This setup will get you over 16,000 rpm. It is a great mod. The venturi size in the stock carb is really small. You can even drill out the stock barrel if careful. Another mod is to set the back nut on the high speed needle to move the spray bar back out of the venturi. May get you up to 17,000. Fun engine to play with. Lots of potential. I think there were some posts on the RCCA website describing all these mods. A mouse can muffler might even help you more. Not sure at what point they redline though. All engines seem to have a point where they let go. The FP was not designed to rev up super high.
What is this application for?

The only bad thing is that I can't find a stock needle anymore. All sold out. I guess the .25 LA uses a plastic carb... so where do I find another needle for the .25 FP? My student is kind of tough onmy equipment.... AND... is this the .40 LA carb you're talking about?

My buddy put the FX .25 in his this week. Its really tight and was pretty nose heavy. Theres not alot of room to move battery and receiver around. Also the servos are set back pretty far. But the engine compartment is really tight with a .25 not mention the additional weight of a .40.
