Motor Recommendation – High-Speed or High-Torque
 

Hello

I have recently replaced my gearbox with a new Lonex Unit (standard gear ratio (18:1), SP120 Spring, aluminum ported piston head c/w bearing, red piston) and feel that my stock ‘grey’ motor is having issues pulling the spring and looking to upgrade. Battery is a 7.4VDC LiPo 25C 1200mAh.

Not looking for higher RPS, just something dependable.

Not sure if I should be looking for a High-Torque or High-Speed motor? I am guessing a High-Torque motor to ensure no pre-engagement of the piston and increased trigger response?

For High-Torque have been looking at;

• Lonex A2 Infinite Torque-Up Motor
• Tokyo Marui EG1000 Motor
• Guarder Infinite Torque-Up Motor

I have seen other threads discussing motor upgrades, and sorry for another motor thread, but looking for a specific recommendation.

I'd always choose a High Torque over High Speed...but a lot of solid motors now usually do more than well enough at both.

The three you listed are all good motors...I like the "plain old" G&P M120 motors as well, good bang for buck

Any torque motor using neodymium magnets will have all the speed you could ever need. And they have better trigger response, which is always sweet.

I'll add something:

To prevent pre-engagement, the motor has little to do with it. It is still possible to get pre-engagement with a torque motor. You don't want the motor to turn slow, you want to piston to come back into ready position as fast as he can.

One step is to lighten the piston assembly. The lonex red piston is already heavy by itself, with the bearings it's worse. If you have a bearing spring guide, feel free to remove them from the piston assembly, as they are not needed (they don't hurt, too. But they add weight).

Now, I don't say you *will* get premature engagement with a 7.4v battery and standard gears. What I'm saying is that it could happen with a strong motor, even a "torque" one.

The EG1000 does not belong on that list.

The Lonex A1 and A2 will be fine for your purposes, the Guarder ITU is not a bad choice as well but it's not as fast or as torque-y as the other 2.

The Guarder motor is very nice. I run one in my Stoner 63.

Another awesome option to look at would be the SHS high torque motors. They're cheap and kick all sorts of ass. Pairing one with standard ratio gears and a 7.4v lipo should put you in the 18-22rps ballpark.

The EG1000 is no longer a relevant motor, they're nice, but they're not neo magnet motors and are not even close to being worth the price.

You shouldn't get much if any pre engagement on that set up, but as already mentioned, the lonex pistons are quite heavy. If you feel so inclined, remove the bearings from the piston head, and swiss cheese the piston. That paired with a 120 spring and you won't have any problems.

I wonder what kind of amps the SHS HT motors pulls, it's been a while since I've owned one...

~19 on an otherwise stock gun.

ZCI has produced a new neo high torque/speed motor - who knows if its on par with Lonex's neos but judging by some of their other products in the ZCI line up I say hells no.

My personal favs are the SHS and Element high speeds.

Seems like High-torque is the way to go..

Leaning towards Lonex A1 or A2, as I have read good things about them all over.

Any thoughts/opinions on a Tienly F5000 motor?

Lonex over guarder itu. Lonex seems to have more speed and torque. Just hope you don't get one from a shitty batch with terrible brushes and pinions.

Can across the below in my Google searching;

For a 120 spring;

A1, A2 and A4 – Possible
A3 and A5 - Recommended

That sheet is BS basically. I'm running the A1 in 2 guns right now, one with a M100 and the other with a M120 and both are fine.

I'm going to be blunt and say that you're not exploring the full potential of that mechbox with a 7.4v battery. Try an 11.1v with your current motor and I can guarantee you that you won't feel the need for a motor upgrade.

If and when you get sick of the trigger response on that setup, then you can move up to a A1 or A2 motor and really start tearing it up.

Without modifying the piston and/or piston head will pre-engagement be an issue with using a 11.1V LiPo?

Are you even getting pre-engagement with your current setup?


Sent from my universe to yours

With a 15C battery probably not, with a 25C battery, yes.

I'm not trying to be deliberately obtuse with you, it's just that there are minor variances here and there and I would LOVE to conclusively say "do this, this and that" and you'll be golden. Often I find myself trying to find that middle ground between not really having to do much work and getting maximum performance for our clients and to be honest it's not really a favourable spot as there's credibility and liability involved. That and we're not exactly in the pursuit of a "just good enough" setup. I'm way more comfortable and knowledgeable fielding questions about how to build a balls-to-the-wall gun than answering questions like "what exactly do I NOT have to do to get something that's half-decent"?

As far as I can tell, no pre-engagement with current setup (7.4VDC LiPo 25-50C 1200mAh).

I assume that it would be pretty noticeable if I was getting pre-engagement.

Doh, the 11.1VDC LiPo I have is 1200mAh 25-50C.

I am thinking I'll get the Lonex A2 motor now and run on a 7.4VDC LiPo (as I am concerned about my stock motor).

Then once I feel like opening my gearbox again I can swiss-cheese the piston, remove the piston head bearings and run my 11.1 LiPo.

Believe the Lonex A2 should be good for both scenarios?

If you're limiting ROF by lowering the C rating, what you're doing is forcibly starving the motor of amperage, and not drawing enough amperage out of the lipo. That's called over-current draw and it's a good way to wreck a lipo.

Just get a battery upgrade bro. Swiss cheesing and removing bearings are not necessary. Pre-engagement really only happens when you get a jam in your barrel or you're getting feeding problems. I have 30 RPS setups doing anywhere from 300FPS to 450FPS, one of my guns ran a M90 spring, lonex piston without swiss cheesing and aluminum piston head with bearings at 30 RPS and no pre-engagement happened.

Went with the Lonex A2 on a 7.4LiPo and all is great. Faster trigger response and higher ROF.
