if you have it sitting too long and you pin it right away it could die on you as it has alot of fuel to burn up. Idk redcat motors but make sure it has smoke, not chugging like a chimney but light smoke when its reving on the box. again idk redcat but factory settings seem to be flush with the LS/HS needles.

When an engine quits, pay attention to how it quits. An abrupt stop means it's lean somewhere. Where in the throttle range it happens determines which needle to adjust. An slow and stuttery stop means it rich and loaded up. Consider the idle needle the one that controls idle mixture and the first 30% of the throttle range off idle. You want this needle set such that it slightly loads up at idle if left idling for 15 seconds or so. When you throttle up, it should clean out fairly quickly and easily and not flameout. If it flames out, you're a tick or two to rich. If you drive at 1/4-1/3 throttle for say 15 seconds and punch it and it burbles a bit and takes a second to clear out (smokey), your idle is still too rich. Set your high speed for absolute best and cleanest (highest revving) sound when the tank is near empty so when the tank is full it's kinda rich and a little smokier.

Redcat uses SH Engines. I've used many SH engines over the years - fairly decent RTR engines. Sometimes a bit finicky, but if you use a quality fuel and good glow plugs, they run pretty good. Race engine they aren't (for the most part), but good basher engines they are, I feel. Fuel with 10-12% oil (castor/synth blend is best) and 20-25% nitro works well. I like Picco P6S plugs for the standard plug engines. They're the best standard plug I've used to date. Hot glow plugs usually cause more problems than they're worth unless you're a very good tuner (generally).
