Hello,
YS110FZ, total hours accumulated about 2-3 hours only.
Fuel is cool power Heli 30%nitro 22%Oil.
Plug is OSF and propeller is APC 14x10. Engine mount is Hyde.

When rotating the propeller it looks like no much compression and in the air looks like
is not generating the power which it should. (I have previous experience with such motor)
fuel tank pressure is buildup properly.

What do you think I should look into to begin with without effecting the warranty?
Thanks in advanced
