ok so i tried lube,then charged the battery fully put the prop,shaft,gear on ,connected it to rx ,and it works fine now with out any screechy noise.

Could it be that the battery was low so the motor was cutting off then after that the rx was turning off for a second or two and coming on again,motor was screeching after i went above half throttle ... so could it be low battery?????? Im suprised how smooth it is again hope it remains the same

No, it's the bearing on the motor shaft. If there is too much play, it vibrates and squeals. The oil will mask it for a little while, but won't last for ever.

I don't know why posting a link to a thread search result always works for a little while then fails.

Just type screech of death in the Search this Thread
