I just got a new OS 46 FX and broke in like the books say. I'm using 15% nitro 18% oil and #8 glow plug , after about 4 tanks of fuel the plug was dead, wouldn't glow at all so got out another new #8 os plug and put it in and after 4 more tanks it was also dead so i put in a #3 os plug and ran it about 5 minutes today and it ran ok. Any idea what is happening to the plugs ? Maybe i have it too rich still ? There is a hesitation when i go from slow idle to full throttle. full throttle is great power on #3 or #8 plug. The temp. is always in 80+ with some humidity. I been using top flight 11/6 and
