Torque/ speed? Help!

[tomdrews]

Hello chaps
I'm looking into putting together a high FPS AEG with the fastest trigger response possible, and was wondering if 13:1 gears would be sufficient and tough enough to pull an m120/30 when coupled with a highh torque motor.
Any help you tech heads could give me would be much appreciated!

It really depends on how good you're battery's are and how well it cycles , if you use good fresh battery's and the gearbox does not stop with the spring partially compressed you should be OK ish but what you are asking for are two diametrically opposite conditions ,what are you calling high fps ? 350fps and you'l be fine , 400+fps and you could get lock up unless you can get the cycle to complete and stop uncompressed .

Would a hard wired active nreaking mosfet do that, do you know?

It would help a lot as it reduces overspin , if you went for 16/1 rather than 13/1 it would still be a little faster than stock 18/1 gears but under less stress , is it intended as a semi locked dmr , if so then you could go to 11.1v lipo ,with a braking fet and 16/1 gears you'd have a reliable setup with good responce .

Lonex a2 motor . Torque and speed , combined with a decent gearset will be all you ever need

Could get an element ultra high torque motor, then you'd most likely get away with the 13.1 gears. However, you might then have the problem of the gun actually running too fast and end up stripping the piston unless you decide t short-stroke. I reckon your best port of call is an element ultra-high torque motor, stock gears, upgrade your spring to like an m130 and short stoke like 3 teeth. Coupled with a 7.4v lipo you'll be sorted. Should keep you at a site-safe fps too. The motor and battery will give you solid trigger response and honestly the only other thing you need unless you already have them are metal bushings or possibly a bearing spring guide and a good shim job.
