I picked one up because the deal was so good and the fact prices have gotten so high.
Without those two factors together I would not have. I have no application for this motor at the time so it will sit until I do.
I really don't know what I anticipate doing with it at this moment. I just knew that they would go fast and it would be a good motor to have for different applications.
Is it possible to drill out an 5mm pinion to 6mm with an normal hand held drill?
im using novak ones, if it makes a difference(found them to be the best durability wise)

enlarging the bore on a hardened pinion is no trivial task. A lathe is the best tool for the job, along with specialized tooling(a normal drill bit will not make it through). Even if you were successful in opening the bore, you now have .5mm less meat at the set screw area, so it is much more likely to back out. Reducing the shaft is a much better idea and isn't terribly hard with a dremel and grinding wheel.
Yeah, was the same for me and since I've got a 1518 and the repair kit for it is non existing I thought that $70 for a quality motor is a deal too good to pass up on.
I know that the 1515 repair kit can be used for the 1518, apart from the rotor, but the price tag on that kit is in the $45-55 range. I'm still beating myself up for not buying two 1518's during the last sale.
Well i ordered a 1717 the other day when this was posted and just received it..Now i know why these 1717s where in the corner of the warehouse... I got a 1717/17 1580kv with a 6mm shaft and closed endbell. which is odd because the heli version has 6mm shaft and open endbell... I'm kinda frustated at this point..

IIRC, the first batch of the car version was mistakenly made with the 6mm shaft.
No worries, you can buy 6mm bore pinions, or you can just do like 99% of other guys did in your situation and grind the shaft down; all you need is padded vice and a metal file / dremel and some digital calipers. Stick the motor in a bag and poke the shaft through it to keep out the filings, then work back & forth along the shaft ( ahem.. ) and keep checking until your 5mm bore pinions fit snuggly. Either that, or sell your $70 motor for a large profit on a heli/ plane forum...
SORRY guys, unfortunately these motors were made with a 6mm shaft (that's why they were off to the side in the warehouse.)
If anyone is unhappy with the fact that they got a 6mm shaft, please let me know. We will give a full refund to anyone who wants to return the motor.
(P.S. -- I didn't know about the sale until after the motors were gone ... and I would have suggested charging $150, and not $80 )
Thanx!

For 70 bucks I'll deal with the 6mm shaft.
I am just happy to be getting one since I already came up with a need for it. I wasn't sure then some planning and ideas just all came together and the motor will fit the bill perfectly.
