[Tokyo Mauri Vz61 Scorpion]

My brief review:

 

It's got a metal upper reciever, plastic lower reciever, the stock is solid. The bolt is metal, and does have a satisfying whack to it (it's not M14 but its nice enough). Shoots ever so well. The gun is very solid, no creaks anywhere. A very nice bit of kit.

[Tokyo Marui Type 89 Review]

Now, how's that possible? You obviously don't know much about Type 89. The burst fire mode is mechanical, which means there's a latch that counts bbs, so even if you make it run off 220v it won't shoot more than 3 bbs at a time.

As Dusk said, it is entirely possible for higher voltage guns to cycle after the cut off lever has deactivated the current. This I believe is called Overspin.

 

On normal guns single shot is achieved by a cam on the sector gear moving the cut off lever to knock the switch out at a certain point of the cycle, i.e just after the gear releases the piston. Add a high voltage and a turbo motor, you've got yourself a 2-3 round burst of semi.

 

Same principle applies to the Type 89's burst mode. Every time the cam comes round it knocks an arm, which moves down a notch, after 3 movements the arm disrupts the current, as per a normal cut off lever. The arm then resets. If you don't pull the trigger for all 3 shots. You get a 1 or 2 round burst, then the arm resets. Next pull 3 rounds etc...

 

Combine your overspin from a fast motor/large current. 4/5 round burst consistantly.

 

iamwozza's Type 89 has now got a 10.8v 2000mah NiMH battery fitted (4 cells in the front / 5 in the stock).

 

It cycles beautifully and shoots really well, yes it will break as the gears are only stock. But someone by then will hopefully have released some steel ones. Although if I recall the only different gear is the bevel gear.
