Phew, lucky guess.  It's going in a JG G36, and I'm not fussed about ROF so much as semi-auto response and being able to reliably pull the piston past a lock-up: I've had a couple of lock ups where the spring was almost fully compressed and the stock mortor just wouldn't pull it that final tooth.

And yup on the diode, I already have an SB260 in all my mortors will be swapping it over.

keep the JG motor (O-type pinion)

and if/when the 140 arm gives out

swap it all over & use the JG arm

which they say is a 22tpa

certainly has a little bit more performance

than std Cyma/G&G stock motors

it was just the weak ferrite magnets holding it back on lock up

when you just don't have the raw grunt the motor stalls

and fuses blow or there is a really BIG spark at switch contacts

when the switch re-opens

The spark or arcing isn't from the motor starting but flyback inductive energy when you release/open switch

on a stalled motor this spark really increases when switch opens

(on std non-mosfet setup or on mosfet this flyback can kill certain uprotected mosfets)

the schottky diodes snub the inductive spikes

but they nick 0.5v schottky to up to 1v for other diodes

so there is a trade off for circuit protection it seems

fucking annoying a little bit more thought isn't used in these peew peew's - but just slapped together and shipped out the door with no consideration at all.

in the geeky electronics world they would be mortified at running motors without a snubber diode & often they would lean to a capacitor & resistor method to quench the spark

I glanced at some of it & just thought it is way way too geeky for me

nah fuck it I'll just use the ICS method at some motors or splice it in on the motor wires on SHS/G&G types as close to motor as possible & leave it at that

Good choice as i said - best of the 3 BD motaaaaa's imho

That's worth £20, I reckon.

"there is a really BIG spark at switch contacts when the switch re-opens"

Yup, I just had to clean up the contacts after what can't be more than 5,000 rounds, thus adding the diode.
