Upgrading a VFC VR16. Seigeteks?

Like 22:1 or 25:1
The faster a motor is, the lower its torque rating is. You can increase the torque rating with stronger magnets, ultimately theres a peak torque before you have to make the motor physically larger.
Pesto has paired a 45k with 12:1s (i think) before for shits and giggles and he was pulling something retarded like 75A.
The torque band of a motor is the range in which it runs efficiently at top speed. On industrial motors, its where they have 100% duty cycle. Ive put a 3hp motor on a 5hp application before, gets to max speed and everything, but had high draw and overheated like a bastard.

The motor will draw as much amperage as it can to get up to its maximum speed, it'll either reach the max possible draw of the battery and run slow, reach max speed and run super hot, or vaporize a winding.

Its not as easy as just pairing any motor with any gears and any spring. Its a balancing act.

Ok heres the thing I'm in the market for new batteries so im cool with making this system function correctly so what battery should I use also, I ran a SHS high torque for months and it was heating up now I've transfered this motor into multiple guns and every gun it heated up in. I dont know if its a bad motor but wverything I tried it kept heating up. My tienly runs a lot more cooler so should I consider a Tienly 35k or 30k? Also battery what should I do I don't mind running a battery bag if I must.

How would you balance my act? 12.1s with a 30-35k motor or a different gear set for my current motor? Also what size battery should I run? I would like to thank everyone on this thread for the help as well!!

Also is there a specific wiring I should use? I am currently using this http://www.airsoftstore.ca/index.php...products_id=69

12:1s with a 30k
with a 400-420fps spring you should be around the 22A draw range, so nothing less than a turnigy nanotech 1200mah 25-50C battery
And the thickest gauge wire you can possibly stuff into the gun.

Remember, you're getting into high performance. The faster the gun shoots, the faster it's going to work through its life cycle and break down.

Compromise is also important. You COULD build a 75rps setup that breaks down every time you field it, or you could build a 40rps setup that lasts forever with proper maintenance.

The reason some of the old guys rant and rave about how amazing stock marui guns is because they almost never break down. But the reason they almost never break down is because their performance is so scaled back. 300fps at 14rps; hard to break anything when there's no load on the parts lol

Very true now this gun will be shooting around 350 fps for my local indoor field. 12.1's with a 30K motor should I still be short stroking the sector? and also I will be running a 11.1v Lipo as thats the usual voltage I run.

[ThunderCactus]

Should get you 40-42rps easily enough.
Short stroke 2 teeth and you should be golden. Make sure you don't have that pesky 2nd tooth on the piston, either.

[jordan.santos1515]

Wicked thank you guys so much

heat in a motor can also be a sign of insufficient amps reaching the motor. If you are trying to use stick lipos that have ratings like 15C 1000mah that have unmarked or low burst ratings, it's likely the motor isn't getting enough amps.

More C and mah, like 30-40C and at least 2000mah. On an m4 that will force you into a brick battery and external battery bag.

ZCI motors are under 40 bucks, I don't see why you'd buy a whole new gear set or batteries to accommodate a motor.

this thread makes me wanna sell my Tienly GT45000 haha.

Starting to question why I bought one lol I waited for them to be in stock meanwhile I stared at the 30k and 35k going nawh just wait for the 45k lol Now i regret my decision.

I thought Tienly45s were cool when I built everything at 45+ RPS. my main gun at one point was 60 RPS on 11.1. They are cool when you want to push the RPS numbers, but aside from that they are not practical. Most people just buy them because higher number means better quloty right?

[jordan.santos1515]

For sure, well looks like I've learnt my lesson now .

So 13:1 SHS + Tienly GT45000 is complete overkill if aiming for 40-45 RPS.
Damn, fell for the numbers game once again.
What happens if I kept my 18:1 stock gears with the tienly ? Is there anyway to salvage this without buying a new motor ? TBH I have a SHS high torque it in right now and I have a BTC Spectre that I'm about to put in. I've already been told to SS the gear set by three teeth.

In sum: aiming for 40-45 RPS at 380-400 fps.
I have in my possession: Pretty much all modify internals (including aluminum piston head and quantum piston), ASC sorbo pads, SHS HT motor, Tienly GT45000, Stock VFC gears (18:1?), SHS 13:1 gears and BTC Spectre. All powered by a Turnigy 11.1v 15-25c 2000mah battery

tienly 30k on 12:1s will give you 42rps
tienly 30k on 13:1s will give you closer to 36rps (since they're evidently 13.78:1)
