I've been using the Phoenixtech DT3826/1900kv motor in one of my 500's for a while now. Lots of grunt!
Recently it developed a bit of a "scream" which I put down to a dodgy bearing. (I'd checked everything else). I contacted the Phoenix guys a couple of weeks ago to ask about replacement of the bearings. Unfortunately they haven't got back to me (I followed my enquiry up with a phone call last week but still nothing)
I decided to replace the motor with the Hyperion 1600kv (made by Scorpion but with better bearings) which is great - love it.
Since then I had a few moments spare so I decided to open up the Phoenixtech motor to have a bash at replacing the bearings. It was a lot easier than I thought.
There is a cir-clip on the shaft which needs removing, then there is a simple brass collar which just slides off. Hold onto the top of the motor and give the shaft a quick tap - the main housing then slides away leaving the motor windings exposed.
There are just two bearings, they just needed a tap to drop them out and sure enough one of them (bottom one) was very notchy.
I didn't know what size the bearing were so I had a look though my spares box and...... it turns out that the bearings are exactly the same as the main shaft bearings for a trex 450 (685ZZ) - yippee I had some - so fitted them, rebuilt the motor, tested - great all done! No noise and smooth as a baby bum.
Problem is now I have a good motor and nothing to put it in - lol
Cheers,
