Default Dynam Waco Motor Failure

This morning I flew my Dynam Waco (using the stock set-up 4s 2200 battery and 12/6 prop) for the first time (and it flew beautifully), but on the 3rd flight the motor began making a loud metallic noise, so I landed the plane. I found the drive shaft/propellar almost frozen and very difficult to turn. It seemed to catch every few mm of hand turning. When I first unboxed the plane I had noticed a mild catching, but being an electric newbie I thought it would loosen up after running. Obviously, I was wrong. The motors of my first two planes---Apprentice and Super Sportster rxr---turn freely and smoothly. I emailed Nitro this AM and told them the story and asked for a new replacement motor. The phone number on their website---626 968-9860---does not work, and the substitute given is only 7 digits long---626 0664---and is therefore incomplete. SO . . . do you agree that the motor was defective OR is there another factor that should be considered Thanks. Gary P.S.--Does anyone have their complete 10 digit number?

Hard to say but normally these motors only fail from defect or foreign objects getting into them. Many hours of use on the motors I have from models in this series.

Dynam usually makes good motors. I've never had one fail and I have 4 Dynam motors that are over 8 years old. Reports of failures that are not due to crash damage are rare.

I called the number and got a response to choose sales or tech support. They also have a live chat function you might try.

Life's journey is not to arrive at the grave in a well preserved body,
but rather to skid in sideways totally worn out shouting, Holy Crap... what a ride.

I wonder if a magnet came loose?

That was my thought as well. That, or some foreign matter in the motor.

I got the original phone number working and got through to Nitro. They told me to send the motor back for replacement. I took the motor off and found that the 4 screws holding the motor onto the X mount were loose, in fact very loose. When turned by hand the crankshaft turns with a clunk, clunk, clunk noise. I don't know what the problems is, but I suspect it was there from the start and damaged the motor even more from flying. As I said there was a little "hitch" in the motor out of the box. I guess I should have notified Nitro at that time. Anyway, I'll mail it back today. Thanks. Gary
