2826-10 motor

I got an ep-10 in a trade and ordered a quick brand 2826-10 motor from Irwin. For sport flying does anyone know how that motor holds up? He claims they come from the same factory as Hacker.

Jimbo, got this from world-of-heli.de:

You need to make sure which version your HK-3026 motors are. The new version uses different bearing. Please read instruction below:

Scorpion did change the design of the HK3026 motor a couple months ago, and switched the internal bearing from a pair of 8x5x2.5 to a single 10x5x4 bearing.

The serial number on the motor indicates the year and month the motor was made. The first letter indicates the year. H was 2007 and I is 2008. The second letter indicates the month with A for January, B for February, C for March and so on. I believe that all motors made since June are of the new design, so any serial number starting with IF or later should be the newer bearing style. Any motor starting with an H, or IE and earlier, would have the 3-bearing set.

The user can also open up the motor and tell very easily. In the earlier design, the bearing tube extended all the way through stator and surrounded the inner bearings. In these motors, you can see a gold ring, 1mm wide surrounding the inner bearings. In the later model motors, the bearing tube stops inside the stator, and the bearing is pressed directly into the hole in the center of the stator.

My flying buddy flies a new HK3026 in his T-Rex 500 with 300+ flights, no problems, not any indication of loosing power.

Cheers,

Back to pinions and shafts.

I solved the problem of fitting 5mm pinion onto 3.17 shaft.
I used reducer sleeve:

Looks like it is Ok. Fits pretty tight.

Also there are pinions of mod0.8. Maybe this will help somebody.
