Hello Everyone,

I have a problem Idesperately need help with.

I have a .60 trainer with an Evo .61 NXengine on it. The engine kills the glow plugs once every 2 flights if I'm lucky. 1 plug per flight if I'm not. The outside temperature varried between 25-33 degrees Celsius. Irun a 10%Nitro fuel and a 12x6 prop.

The first plug that died was the original Evo plug. Then, I wasted an OS #8. Then, an OSF(being longer it suits this engine better), and then another #8. I am unable to find a solution.

I admit that in the beginning the mixture was way too lean - the prop would spin at 11,500RPM(maxIcould ever achieve). But then Irichened the mixture, and then richened it some more. Last time Iflew, Ithe engine would achieve max RPM of 10,000 (quite rich). Yet again, after landing, I'd notice that the plug's coil / fillament would be all sort of chewed, or rather, collapsed.

I am in no way able to solve this puzzle and need serious help Iwould be highly grateful if you could share any thoughts.

P.S. I ordered a Cold O'Donnell plug out of desperation, and a #8Fox Pro Long plug.


Thanks in advance !
