I have a Dualsky 6355DA-12 mounted on my Wind S Pro that has been flown twice at the US Nats; motor is going strong and it has 1000 plus flights ! I will be replacing the bearings for preventive maintenance as soon as I can find a replacement as they are out of stock here in the US. I would buy a spare motor and possibly install it in another project but just like the bearings they are out of stock ... has any one flown with the 6355DA-10 ? Would like input on this one as it is the one available for purchase at the moment ...
