raw sound when spooling up....
Hi,

This evening I pogrammed my esc and tested it on the bench. After feeling comfortable with the settings I put the motor in the X400. Spooled up a little without main blades.... increadible 'raw' sound occured. I repositioned the pinion several times but the sound still exists. Took of the head to assure the sound was not coming from the head as I suspect the main gear to be the cause.... still this horrible sound..... I now the main gears a hardly round (more oval I would say) but does anyone else experienced similar sound?? Otherwise, how to lose it ?

Regards, vincent

Hi,

I checked it and can confirm it is solely because the main gear is more like an oval than a circle..... I tried the 'sand paper' method to shape it and it the sound has decreased but it is still not acceptable to me.... so I'll by a new main gear but.... are there a round ones to buy? I know there has been some talk on an upgrade some time ago but I still haven't found it available.... Any ideas?

Regards, vincent

You think waiting on parts in the mail is bad. Try doing this hobby from IRAQ!!!
