Systema or G&P

[L9OBL]

I've been building myself an m4 AEG from scratch using new parts and some i've stolen from a couple busted AEG's of mine and finally got it done. Low and behold the motor I pulled from my AR15 isn't strong enough for the new gun. The AR15 clocked in at 380fps at 11RDS/s (well 11.4) and im using an element 110 (or something), rated at 400fps give or take the standard variations. So I was going to use the "golden eagle super high power" motor from the AR15 until I had the money for new high torque gears and a new motor and suck up the low ROF but im guessing the spring clocks in at a velocity higher than posted (probably one of the rarer high velocity variations i guess) as the motor won't pull the spring (and I have done upgrades with power gaps like this and not replaced the motor untill the cutomer had the money hell I've done one from 370fps to 410fps didn't shoot w/ a high ROF but it worked till he could replace the motor). As I don't have the money for both new gears and a new motor (and I have high torques [theyre only on the lower torque up end but they'll do] in the gearbox already) im getting a new motor my only problem is should I go with the systema A-Z motor or the G&P M170 i'm leaning towards the systema one but i've herd good things about the G&P so im going to see what you guys think.

personal experience: systema motor sucks. It sucks the battery like crazy and a customer of mine had a systema magnum which heated everything and melted the contacts. I've seen more problems with systema motors than positives. Go with G&P's Devil.

Thanks alot. I have never used a systema as they are usually too expensive for my customer's price range so i don't know alot about them aside from them supposedly being powerhouses. Glad i researched it and asked around about it. So once again thanks.

G&P, heard Systemas suck and I LOVE my G&P M160

Ditto on the M160. A Magnum/A-Z DOES NOT offer 2X the performance or efficiency of a G&P M160/M170. So why would you pay twice as much?

Sounds to me like it's the gears you need to replace, try using double torque gears.
As for the motor, strongly recommend G&P over systema. My M140's have no trouble pulling 400fps at 900-1200rpm. Especially since I use a triggermaster I can tell you the systema's are powerhogs until they get shimmed, turned and insulated. The G&P M120 and M140 motors I know don't require tuning to be using with an SW-COMP, but no motor doesn't benefit from a good tune up
