I honestly think the problem is that the 9.6v battery coupled with the systema turbo motor and m90 spring produces way too much torque. I think the problem is with the Systema motor itself. When I ran this rig without the mosfet it was overcycling like hell (and breaking pistons). Now it's just breaking pistons from time to time. (I play airsoft about 4 times a week out here since I work at night - Just saying because the mosfet cure was not too long ago)The motor has a lot of torque. When I ran on a EG700 or even EG1000 I had no problems with piston breakage. As soon as I put the turbo motor in I have been breaking a piston ass end every other game.... about 2k or so bbs later.
I could be wrong... please tell me if I am because I'd rather have a polycarb any day of the week.
The current piston I have in the gun has lasted me 3 games so far... I think it's a good one but the reason for this post is that I just KNOW that it's going to end up failing. I honestly just want to know the con's of the aluminum piston.
I think M902323 (sorry I can't remember the numbers) summed it up perfectly when he said that it's really a choice between breaking a piston in the sort run or breaking the gears in the long run. I honestly just don't want to operate on the gun right now for a long time... it's a time sink.
Is the danger to the gears that great? I have prometheus high speed gears installed.
Thanks for all the input.

It looks like the imbalance is coming from a slow forward movement of your piston. An M90 spring is not fast enough to return the piston to battery before the sector gear comes swinging around again, which is why you're experiencing a collision. Increase to an M100 or chop out the 2nd piston tooth or short stroke the setup. ... or do all 3. If you don't feel like doing the short stroke mod, at least try moving to the stronger spring and taking out the 2nd piston tooth first. It's a relatively easy mod to do on polycarbonate, but regardless, it looks like you will need to perform at least 2 of the suggested changes/mods in order for your setup to be balanced.
Fix that issue of collision FIRST, before considering upgrading to an aluminum piston. Otherwise, you'll be wasting money with yet another destroyed piston, OR the added stress on the gears will strip their teeth, assuming the piston doesn't get stripped first.
