Hey guys. Here's the deal with the High Speed Needle though, if i run it IN from Flush, it'll give me pretty good performance, but raises temps fast. Now if the High Speed Needle in OUT from Flush, which is how it's suppose to be, holding the trigger on the transmitter makes it dash out, but the RPM starts to die, and shut down immediately. If the Low Speed Needle is in too much, it'll over heat too. If having both needles OUT, the truck will not start. So there's always something in the ways i have tried. Currently, i gave up, put a drop of After Run in the engine and put it away for tomorrow to see what the hobby shop says, and if they can give me a hand. If they can't, Ken from Cen Racing says to send it in.
