Status: offline 		....some engines just lean out in flight more than others, and need to be set
way, way richer than what you would expect at launch. I set a .15 engine
for a guy a few years back, and it needed 12 clicks richer than what he had
it set. Launching an engine that rich doesn't seem right to the some.

It takes about 2 full laps for the engine to get to its full blast setting, and up
to full heat. It will be running rich till then. I never figured out why the smaller
engines need to be set this way.

After the second lap the engine will be set at it's optimum full heat, full throttle
run....and will reward the operater with a good, long flight.

If a small engine is over propped, it will make the problem worse.

FBD.

Status: offline 		is it holding a stable needle setting before launch ?

almost sounds like it is buzzing the fuel once in the air.

Try this.. quick experiment.... use a different prop. One size larger (9x7 would do) just to drop the rpm a bit.

See how that works.

you may have just got a new ENYA if so they take tanks to loose up, must run richer as said, try 5 tanks then fly on 9x6 prop.
