thanx for the replys and jaka for the pictures (agan) lol !!

now that you guys mention , if the motor is warm , say i put a hair dryer on it , to warm it up , or its been running .... it turns smooth ! the prop does a full 360 degree rotation if i just flick it with ,my finger , but if its cold and i flick it , it feels sticky and only does a 170 degree rotation , before i start ripping my engine apart ,,,, which i REALLY dont want to do ... what oils or sprays such as Q20 , fluidfilm or WD40 can i use to spray on the bearing ?? i knw i sound so stupid askiing these questions ,,,, but its my 1st nitro engine
