Motor only works when I hit it

On that build I would use the 30k.
I'm guessing the TPA would be about 16-18 so it would be a good option, however I recently tried an SHS HT (not sure which gen), and on a 7.4v it caused the battery to heat up slightly and swell (only somewhat).
Along with shorting the temperature fuse on the mosfet (I assume) so it would work intermittently and the back end towards the battery would be warm.

On 11.1v it didn't seem to have any issues but was noticeably quicker and due to the lower torque of the motor, would not stop as fast so it was able to spin a bit too far and double shot.

To run your suggested motor I need to try and remove a lot of resistance (already removed a fair bit so could be hard) to use the 7.4v

Or run an active braking mosfet.

Alternatively I use the higher rated TPA motors as I do not need speed and when I do use full auto, I don't care for RoF in the slightest.

you might have to bite the bullet and buy a new motor

but your old one can be re-used to make a nice torquey one no matter what
Thanks for the round up of motors there,

And yes I will most likely be buying a new motor as I think if I remember a while back I've actually stripped the set screw on the pinion but put lock tight in.. so I think unless I get my dremel out it's a goner at the end, would be easier starting again and saving the magnets for another day.

So I'm thinking it's between ZCI HT and ASG 22K, unless you have cheaper alternatives, I don't mind if the motor is higher than 22TPA as I won't be using full auto and as long as it's above ~20TPA to stop overspin, I'm happy.

 
If you're only using semi auto then the 16TPA will get a bit warm and stress the battery. Really nice combination with 13:1 gears on 7.4v for a full auto/occasional semi gun though. 22TPA is your best choice. Lower start up current so less battery stress with rapid semi auto use.

So no need to go mental with a 28tpa+?
Also any advantage for ZCI vs ASG?

Feeling lazy as the gun is already shimmed within good tolerance for another ZCI... :P

can send you two or three D type motor/arms just pay postage (fiver)

cyma is 27/28 tpa - unwound one but wire broke so hacked the wires and counted

chaoli likely 28tpa but crap varies - could be 28 or even 32

 
The ASG 30K won't stress the battery on that build and will give you a good middle ground between ROF and trigger response. You would be better using a AAB fet with the 11.1v battery.

I tend to use that motor for everything lately.

 
Depends on the battery....but I keep coming back to the ASG 30k for most builds too, although the 22k on 11.1v and 13:1 gears with a 9 tooth bevel is nice for rapid semi auto with heavier springs.

Op is claiming 110 with an 11.1v lipo so should be good. 

22k is good for Dmr builds

Sitting Duck is helping me out with a spare 28TPA, which is overkill for a cqb semi auto on SSG but it means I don't need to pick up a mosfet with Active Braking (yet). Or worry about any sort of heat issues.

Run that till it dies then grab a mosfet with AB or a TITAN + a slightly less torquey motor.

Good old Duck the man is a star.

2 x Cyma armatures (right side with white gluey bit by commutator end)

both with D pinions, seem OK, sit at 90 degrees with a JG bevel

so "should" sit at 90 degrees with a SHS bevel & others

Cyma bevels are cut funny sitting at 85 degrees so not all teeth mesh 101% in situ

(think I found a few odd qwirky pinions that sit with cyma bevels better for next cheapo build)

Anyway.....

2 x Cyma's on right side with OK pinions (D type)

one pinion is a bitch to get on the other Cyma/Chaoli

but other pinion fits on all 3 armatures

1 Chaoli on left from f*ck knows where....

(but some people crave/rave about them)

28tpa for me on 7.4v is a bit slow - fine for 3 cell mofo's

Fairly sure they are 3 x similar looking 28tpa mofo's

Was gonna send an end bell (tee hee bell end) from each type

so you got some spare brushes or stuff

but might as well send up 2 motors complete & spare armature and be done with it

The long shaft guides are just crap solid scrap alloy

I'll chuck it in a small box and send it out tomorrow I guess

Hopefully you should be able to get a new lease of life in your gun once again

Have my babies..

But in all seriousness thank you for your help, really.

PM me your invoice :)
