Scorpion 5020-450 rewind

[pustinek]

Hello!
I have at home spare motor from my Logo 600se. And im getting goblin 700 soon. And i was wondering if this motor can be rewinded so it has abit more kV and if it can give any more power out?
If it is possible is there any person that i can contact for the job or any instructions to do ot myself?


Thanks best regards Kristjan!

Hi Kristjan, unfortunately i can not link you to how to do it as Powercroco closed his site down, its a learning curve, quick to do if you have the right information at hand tools, wire, paper etc.
Soon i get time i want to make a quick guide and video about this but too busy now. I would not spend a lot of money to rewind the 5020 as a 4035 mk3 is a stronger motor and will give you more power. Esc's are not very partial to motors where the stator length is less than half the width either. The new 14 pole kontronik seems to work though so it depends on esc, pole count etc.
In Europe Dekker and MAuro can help you out, pm them!
