I'm a newbie. I have a Raptor 30 V2. I've run 6 gallons of fuel so far on the motor mostly hovering with no crashes. The Webra 35 is driving me abit insane as needle valve setting seem to change. One time it's rich and I lean it out ,,runs great and the next tank it runs like crap again. The backplate is cool to the touch after landing. Today I had it leaned out to about 3/4 to 7/8th of a turn out from closed. Still lots of smoke and ran great ,,next tank was rich and wouldn't hover till full stick. When running well it has great power but isn't consistent. I run cool power 15% and have used new OS#8 plugs. I also at the advice of Horizon Hobbies RTV'd the Oring area of the carb[also cleaned it] as they said they have had problems there and it would cause the symptoms I described. They also said they run 15 and 30% nitro with no problems on this motor.
I want to learn to fly and just need a reliable motor. I know OS is the one in that department but I would like to make this little powerhouse work well.
Any thoughts would be great.
