Default Flame Outs!!!!

Any advice? Since moving to outdoor season(much larger daredevil jumps!) we have struggled severely to run a complete race without motor trouble. I'm trying to be patient with learning to tune but very frustrating. It seems that the engines normally die after 'crash' landings or flips. Is it normal for the engine to die after casing a jump, don't know if flywheel is hitting or what.

Tuning is an art, it depends upon the wheel man, weather, track, traction, bearing condition, clutch condition, tire choice, engine choice, etc etc. Practice like a matha fool and figure it out

sometimes the chassis flex in a sutuation that will hit the clutch bell and stall the engine. a fix that some guys do is going to the king headz extended engine mount or most just add washers between the engine and mount to lift the engine up a little to give the bell more room.

Found probable cause, maybe will help some other newbies like me. Found that if you don't rev the gas during the pit stop, post pit flameout goes away! Learn something new everytime we go out!

rev three times quick before the pit , when lid opens off throttle , rev rev rev with about medium throttle as soon as lid closes , keep blipping throttle for a few corners after the pit stop .


or have the engine tuneed properly trust me guys , i screwed up alot of engines figuring out how to make them run properly , now it is like second nature to me . take your time and pay attention to the guys that have it figured out already

Using a clean-burning fuel like Cold Fusion helps to erradicate (oooh..nice word!) those pesky flame outs as well. Helps with the idle too!

+1 on what rcgeezer said

No flameouts since I have been using coldfusion fuel and I mean NO FLAMEOUTS... Engine tune, proper idle and fuel are the primary reasons. Sometimes a plug goes bad as well.

I wish I could be at Madera this weekend to try it again but doesn't look like thats going to happen. Good luck and maybe see ya at Delta next month. Oh yeah, don't know the driver just the Truggy and name.

I stuggled with this same problem for my first year of running nitro offroad. My simple rule of thumb is that if it happens, I'm running the bottom end too lean.

I haven't been proven wrong yet.

Cache Ya,
Craig.

Sounds like you RICH -I think maybe when its landing you get off the throttle and it just overloads with fuel and when you go to hit the throtte it dies
