Go to the redcat support forums and they can help you out on tuning. Best thing to do is set it back to factory settings and go from there.

YUP! WHAT HE SAID!

I DID THAT AND IT STILL WONT RUN WIDE OPEN AL I CAN GET OUT OF IT IS HALF THROTTLE IF I GO WIDE OPEN IT BOGS AND POPS AND STUDDERS ALOT THEN DIES

They only problem I had with mine was I had to reverse the servo because it was working backwards.

I WOULD CHECK YOUR CANOOTER VALVE THEN I WOULD CHECK YOUR MUFFLER BEARINGS. This forum so desperately needs a caps lock filter.. reading people who post in caps makes my brain hurt.

You most probably have one of the following problems.
1) an air leak in your cases - take it apart and re seal everything.
2) an air leak in you carb - Check carb seating and O-ring and needle valve seals.
3) leak through you bearings - Replace bearings
4) your cylinder liner/ piston is shagged - replace (or just buy a new engine)

Do everything in that order with the cheapest being first and it might not cost too much
