Spoke to a motor builder and he explained the process of removing the arm, putting in a blank and zapping magnets. With that said, since the Hawk 7 is a sealed motor can you really zapp the magnets in this can or does the armature absorb the energy?

I'm always confused about all the different "Hawk" names for the JK motors. I think they should come up with like different names for the different motors... you know, like Hawk, Eagle, Falcon... OK, not that one :D but, Owl, Osprey, Eagle, Vulture. 

Anyway, doesn't the "Hawk 7" use neos of some sort? If so, zapping those with a regular home-type zapper isn't bound to do anything good regardless of whether or not a slug is used. I've never tried zapping a motor with an arm installed instead of a slug for a simple reason... a motor with an arm won't fit.

Read THIS and PART II.
No matter what all the experts say, there are still racers who swear their so called "Turbo-Blasted" motors are faster.

As you can see most of the "zapped" Hawks had a higher reading for their magnets. So they can clearly be zapped with the arm still in the motor. It takes a different zapper for the Hawks and they are very expensive. 


And I can say that from personal experience, that the "zapped" Hawks are not any faster, but as they heat up during and cool down between heats, they seem to keep running more consistent lap times and do not fall off as much as "non-zapped" Hawks do in the later heats.


And I get more laps out of a "zapped" Hawk before they are not competitive anymore.

I thought that in order to zap magnets, one has to eliminate the air gap.

Certainly not with cobalt magnets, in an air coil, at 500-700 volts.

My take on zapping a sealing motor is you can change the orientation around, but I don't think it will improve it as I've never seen an exceptional zapped sealed motor.
