F/S: Scorpion HK 4025-1100 Needs work

Hey guys,

Well i have a scorpion HK (helicopter edition) 4025-1100 Motor for sale here. First off this is sold AS-IS. I will do my best to describe it and my pictures should help. There is a pinion stuck on the shaft and i decided to try to dremel it off. Well this thing wont dremel off very well and ive finally just had enough with it. To the best of my knowledge i would say it just needs a new shaft and bearings which cost

5.99 for bearings:
8.99 for the Shaft:

I just dont feel i have the skills to replace the shaft and bearings my self so i am selling the motor for someone else to do it. Keep in mind this is a used motor and has had about 20-30 flights on it. It has some cosmetic wear on it and im sure alittle internally as well hence it is sold as-is.

Best offer gets it. it is a 115$ Motor and only needs about 20$ In parts. so hoping for a decent amount but all offers accepted unless its like 20$ or something

Pics up SOON waiting for the batt to charge enough

A tool called a pinion puller is what you use to remove gears without going though what you just went though.

I tried and tried pinion pullers and other methods. Nothing would work its like it welded itself to the shaft. The shaft goes from 5mm to 8mm internally and it got jammed onto the part where it gradually gets larger.
