I live in Greece and my fpv friends here do not use Cobra motors, So I can not find any spares.

I would really really appreciate it if someone could donate me an old motor OR just the coils....

THANK YOUUUUU

So sort of like this? (Note he wire length)<br /><br />
Those are nit old cobra, those are the champion range still available.
The old cobra 2205s were labelled 2204

Rewire it if you are desperate.

I have already considered that option...
But i don't have this knowledge.
Moreover it must not be as simple as one might think.
Each of the three wires consist of 3 cores. so 9 wires in total, in a very confined space.
I am not sure I can manage, or if I get close to repairing it wthat the result will be like....

It would be better to buy a new one or get a used one by you guys....
:-)

The knowledge is easy to come by and the theory of the rewind is not that complicated.

But doing it is a different matter  ::)

Getting the boogers apart without damage is quite a feet in it's self.
The rewind is a bit fiddly.
The end result, that warm feeling inside that you did it.

Removing the stator without damaging alluminium parts was the most difficult part...
now I am on the market for the wires....

@atomiclama
Thanks for offering wires, but sending to Greece will have some posting charges anyway!
I will try the local market these days.

It seems the wire was 0.35mm

I found a bit of wires.... for 10€
0,35
0,50 (this dimention equals with two wires (of 0,35mm diameter) in parallel - as the guy in the shop indicated)

<br /><br />*Cobra motors had for each phase two wires in parallel, with 11 revolutions each.
