Correct spring installation

Does it matter which way the spring is inserted with an unequal spring ?
Should the tight coils at the end be against the Piston or retainer?

Tight coils go on the spring retainer


Awesome @Rattler.
Just thought I’d check while I have everything apart .
I ended up getting the high speed well motor to keep me going but I will get the chi hai that you recommended when my local has some more in stock.

Have you got any idea what the specs on the wells motor are? Iv got one sat there because it cane with the new metal wells gearbox and I decided to use a chihi. Might use it elsewhere if it’s any good?

That motor is ok, it seems to have half decent magnets compared to other stock motors and has a good balance of speed and torque, I don’t know the specs sorry.
There is one issue with it ! The shaft support does not support the shaft at all so I would not use it without replacing it.
