Dont think you can replace it yourself, sent it to Pletti for repair.

Thanks for your reply.
Your photo is greatly appreciated.
Looks like all I need to do is simply replace the shaft/armature unit instead of trying to re-straigten, right?

I've contacted icare-rc.com for a replacement. They are in Canada and are the distributor for N. America.
Thanks again for your help!!!!

FYI: I received a quick reply from Etienne of icare-rc.com that the shaft/armature unit would cost $40 and would be difficult to replace.
I declined and will invest in an outrunner type instead.

$40 for just the shaft or the shaft/armature combo?

Doesn't look like it'd be that difficult to replace if you have a bench vice.

What's the worst that could happen, possibly break it? Oh wait, it already is.

It's just me but I love fixing things people say can't be fixed.:D

If im corect the chaft is titanium and hard to produce, what did you do to bend that trong chaft?

If you want a high quality outrunner with simular performance you could have a look at the Kontronik Dancer Maxi... very fine 16pole motors from germany!

72 g
2-3 LiPo/ 6-10 Nimh
Max effekt ca 250 watt
1200 varv/ V
3,17 mm chaft

The center pic is a Micro dancer, not maxi.

The $40.00 was for both.
I nosed in at 4ft altitude at full speed upon take-off. I was surprised to see the shaft was bent, guess titanium isn't that strong after all.
thanks for the tip on a replacement motor.

I now notice that it was a Freestyle 24 you had, the Maxi dancer have simular kv as the Freestyle 20, little bit more rpm than the 24 wind, for lower kv motor the Torcman 280-10-30 is more simular to your freestyle 24.

Hi,
It looks simple to repair from the photo. I would be pulling it apart and having a closer look. You may be able to remove the shaft from the rotor. If so you could try to straighten the old one, or better still replace it with some round High speed steel (drill rod) which you should be able to get from engineering suppiers (cheap but very strong; no need for titanium).

If not send it my way!!!!:D :D :D

Best regards and good luck
Phil
