High Torque Set Up Requirements

[Bar1975]

So i have this CYMA AK47 that is an electric recoil/blow-back model.

Love the gun and thought it would benefit from an SHS High Torque motor (The piston pulls back on a weight that then drives forward and recoils the gun while working the bolt action as well..

Today on the field the gears stripped .. i just took it apart and the SPUR and SECTOR gear had teeth ripped out of it.

My guess is the high torque motor was too strong for the stock gears. (CYMA normally has pretty decent gears stock.. especially their AK models)

So ... im looking at either reinforced standard gears or reinforced high torque gears. I run an 11.1 lipo with a madbul M120 spring.

What are the particulars of high torque gear set ups?

What gear set would be a good option if i decide to keep the blow-back engine? (I would imagine pretty strong gears) Would these gears work if the blow-back was turned off? Would one set be good for both set ups?
