weigh piston first.....
just under 20g is what I aimed for on last few builds on complete piston
a set of full steel teeth & an ali head can get up to 30gms with piston bearing
some cheap lightweight pistons can be as low as 13gms but didn't look robust for a hi speed setup
swiss cheese may only reduce weight by about 3 or 4gms which equates to all steel teeth or ali head
In a DMR with higher spring a bit of weight is ideal but if going for hi rof then a lighter piston is required
(but without losing too much strength)
For what its worth - if you have a set of scales then use them to check weight of piston
you would be suprised the difference when you compare a few pistons and it can make a difference
If using hi speed gears 13:1 or 12:1 and piston is a bit heavier then you may get pre-engagement &
that may require short stroking & a slightly heavier spring if this happens.
You can nudge 30+ on stock 18:1 gears if you get your homework done with a hi speed motor
hence I said 18 or 16:1, half decent 20g or less piston should be fine with 1 or 3 steel teeth for most peeps
as always take time & triple check everything turns/slides smoothly as you rebuild it.
always check any parts you replace fit properly - sounds obvious but often new parts may need a bit of sanding
or filing to fit into gearbox and close up perfectly. Failing to check a new part fits will often lead to snap or bang
weigh the piston if you can and you may not need to use all steel teeth/swiss cheese piston unless you are going nutz
I think it already may mosfet in with electrics on gearbox as well as all steel piston:

but should of been able to handle 11.1v really and if review guide was saying rof is 15 then sounds like 18:1
and just a torquey motor rather than torque+speed motor in there:
But when the situation demands, you can rock full auto and get around 15 rounds per second down the barrel to your opponents at 300 feet per second, which is great for CQB games.
Anyway - looks like all steel teeth piston - maybe weigh it and see, could swiss cheese it
but also the steel teeth could of contributed to gears shredding if box jammed
instead of just having a piston snapped at the initial pickup tooth perhaps ???
(probably never know for sure how all gears & motor shredded inside now)
