Hi!  I bought the A-10 a few weeks back.  I upgraded the battery with one of your blue lipo 1300's 11.1v.  I did several test runs on a platform checking motors, power, etc... running 1/2 to 3/4 throttle and all was good.  (Intent not to blister the motors without a gentle break in.)  My weather today was finally decent enough to attempt the maiden. 

However upon running down the runway it appeared to be very underpowered and that's when I noticed the left motor was not spinning.

I changed esc connections to the good motor as a test to rule out the esc/wiring.  So it appears to only be one motor causing the problem.  Could the motor have been faulty?  (One thing to note is that the center screw did have to be tightened on one occasion and the fan housing did show some rubbing.  Not sure if that matters)  Is there a way I can get a replacement motor or would I have to order a new one?

Thanks sincerely in advance for your response.  My order number was 17210252890263+104731+5180453286decc573be4

Sincerely,

loyal customer (Brent)<br type="_moz"/>
