I am planning on modding my stryfe, and just cracked it open. I am interested in doing a voltage mod, but don't want to fry my motors. Is there any recommended voltage that provides upgraded velocity and performance but doesn't burn out the motors? I'd prefer to not have to buy new ones. 

Thanks,

From what i heard it's around double stock voltage before you start destroyig your motor's. Most people who use stock motor's use 2 - 3 imr batteries and some dummies. 

 

(might even use trustfire's if you are feeling frisky)

Will the motors eventually burn out?

I don't know if they burn out at 2 imr's but they do eventually burnout at 3 imr's

How long will they last? Will upgrading my motors at a later point and adding a lipo eventually burn out those motors?

Brushed motors, such as the type installed in a stock Stryfe always "burnout." Their commutators/brushes wear away and/or their bearings fail and they become useless. When upping the voltage and current sent to them, you will inherently reduce their lifespan.

 

So by using 2 or more Lithium (polymer or ion) cells, you will reduce the motors' life. By how much is pretty much speculation, but logic says you'll get shorter life the higher voltages you use.

Ok, that makes sense. Will buying higher quality motors increase that time? If I go above the recommended voltage, is there any way to know how much faster the motors will die?

It depends on specs of the motor.

 

Not without looking at a spec sheet or doing experiments yourself.

You should watch Foam Data Services's video on motors : https://www.youtube....h?v=Oyqm1QnIwOM.

 

 

This covers a lot of stuff about stock and aftermarket/3rd party motors.

Actually, ALL motors eventually fail, they just have different fail modes.  Brushless motors can still have bushings/bearings fail, and vibrations will still work harden the thin wire used in the windings causing them to break at the commutator.  

As for the OP's question, you are going to have to deal with the motors burning out eventually either way with a voltage upgrade, it is inevitable.  The stock motors use flimsy metal brushes that will fail much more rapidly as the voltage is ramped up.  If you want to hold this off, I wouldnt go over 2 cells (about 8 volts fully charged) from IMRs or a lipo.  This is a minor upgrade though, and wouldnt give you the performance you would likely see from better carbon brushed motors (even at a lover voltage).

I currently run 3 imr 14500 800Mah and a dummy on all my FWB. Works pretty well and I haven't noticed much degrading of the motors. Its a huge performance increase but not recommended. I have just purchased a dozen MTB HoneyBadger motors and plan to upgrade to 2s Lipo on all my blasters. I really do not have a need(or see a significant value on going 3s, plus the MTB Rhinos are hard to get and I'm not going to 180's....

Of course they do! But you can't be implying that operating brushed motors within specs will last comparably as long as operating a brushless motor within specs.

Sold out still. I spoke with MTB and they are backordered for a while still . I order mine direct from blastertech.
