hmmm - i'm definately no nitro king -lol- But i can throw a couple tips at ya i guess till someone else pops along -lol-

When you gave it throttle - was the engine 'bogging' down really bad and lacking power? Does it just stay bogged down and then stall, or does it clear the fuel mixture out and start to run a bit?

If it bogs and stalls - there'es too much fuel mixture passing through which bogs dow the engine, cause it cant burn all the fuel - lean out the low speed needle for that...

btw - with the 3 tuning needles - are you up to scratch with them? Idle/High Speed/Low Speed needles/screws?

You wanna just run up and down a 20meter or so straight then u-turn and put along the way back - do that for the first 6-8 tanks i think.....try not going over ½ throttle untill about thr 4th-5th tank :)

Another suggestion is to seal up that poverty pack primer on the fuel tank - seal it up - and when you need to prime the engine with fuel - just hold ur finger over the exhaust tip and crank the rotor start for a sec - watch the fuel pass along the fuel tube and into the engine :)

Temps are good around 130-180 max i think for the mach 26....

oh yeah - the engine will automatically lean itself out when the fuel tank gets low, cause the fuel isn't there for the engine to pick it up ;)
