Hmm, 14tpa for the Lonex vs 16tpa for the SHS High Torque...
Make that 22tpa for the new generation SHS High Torque.
Well if you head over & reg at Airsoft Mechanics they go into all this TPA much much more
BUT - they said I think the SHS Torque was 16tpa - wtf ???
Nah - really think they mean the SHS Speed motor is 16tpa
The Big Dragon M160 is a 14tpa and that is pretty damn quick
There is also a red cheapy motor on DX Extreme and f*ck me that is quick like the BD M160
Oddly enough the cheap £24 red dx.com is wired up incorrectly - well about 3 of them were
The red terminal is actually the negative - think they put the cap on wrong or the magnets ar$e about face
BUT like all very fast high speed motors they WILL draw more amps which drain your battery & run hotter
It is also not just the tpa but the thickness of the wire used in the winding plus the strength of the magnets blah blah blah
So every gun build will vary slightly depending on spring, wiring with next to no joins to reduce resistance,
bearings/bushings - bearings will be quicker but bushings will tend to last longer I have found or a mixture,
Shimming, motor height/angle - all these factors will affect the amps/rof/load etc......
Plus revisions in motor(s) & spec - not tried the element motors etc.....
SHS or Rocket are a good go to motor that won't break the bank and a pretty safe recommendation I feel
Any rof I give are to be taken as a rough guide only could be a few rps either way - though to get high 20's on 7.4v takes some doing
of course a 15c lipo is not wise min 20c - I use 25c mainly but a 30-40c also ups the rof a bit more too....
eg: std gun 7.4v 20/25c might do 13 rps on 18:1
add deans & mosfet maybe get 15rps (mainly from deans but also good rewire if fitting mosfet)
replace slow stock motor with shs torque should up it 30% aprox to near 18rps - perhaps get 20/21 on high speed motor
gear change to 12 or 13:1 should get you 23-25rps on torque motor....
avoid chucking in 11.1v or pushing guns past 25rps I'd say as it may overspin and serious overspin can mean you get close to PE
I mean you can go faster but it needs a bit more work like ShortStroking
USA guns can use higher springs so they are ok until say 30rps before needing work/mods
In any case the faster it goes usually the faster it wears/more heat etc.... so we usually say:
in the twenties is plenty
You can run a gun on higher juice 9.6v or 11.1v though contacts may arc a little long term
but when you gun overcycles a little - on a fresh battery a little overspin is ok
But if she double fires on semi when you start pushing more juice I'd ease up on the juice
shredded a number of pistons taking the pi$$ or bevels on all metal rack pistons
Somewhere around 25rps is about the limit when you may need to ease up or do more homework on overspinning
hence creep a gun up to about 20 or low twenties and you got a snappy gun that shouldn't shred too quickly
(a few more rps you won't notice & it is the player's skill than the extra rps fire rate that usually wins the game)
Jeez another waffle post - hopefully you should get up around the 20-25rps and be happy without too much grief
