Raptor question
just wondering...
Lately when i am hovering my raptor will gain rpm's and drop them with out any input from the sticks. Im running the os.32. Actully it sounds like its gaining and loosing head speed, is this a problem with the clutch? the bird will climb and drop 10 feet or so all on its own.
Thanks for any help.

Sounds to me like the engine is leaning out. But I could be wrong. How long has it been since you changed the fuel lines? And what type of fuel are you running? Anything been changed on the bird recently? Where is your high end neelde set at?

it really sounds like a engine problem, check the glowplug etc... and have a look at the clutch. any problems with full power climb outs ?

I normaly run cool power 15%, but recently tried some cp 30%, i changed the plug, which is an os # 8. I haven't changed the fuel lines, i have about three gallons of fuel through it. I flew it again tonight and I think the clutch is making some noise, Im afraid its the famous wah wah. Also I measured the engine temp, its running around 185 F. I think this is too cool so ill try leaning it out a bit.
Oh yeah as far as full power climb outs go, it does seem to have a reduction in power. Just kind of weird because everything was fine yesterday. Anyone think the change in fuel could be the cause?
Thaks for the help!!!!! I'll try all the posted suggestions and let you know what works.

May be
I am not too educated in Helis but I am wondering once the clutch is engaged with the bell would it partially disengage while engine running at same RPM ? Or it just slips and looses grip 
Do you have all the linkages and arms tight with almost no slop ? (I know rappy is sloppy by nature..hehe , this is in context with those screws going thru bearings ..)
