Hi brainstrust,
Hoping someone might be able to recommend a 480 long motor to suit a SRC SR4 blaster.
After something that’s cost effective, will give the blaster a small bump in RPS but not something so fast that it’ll wreck the gearbox.
I’ve been looking at this but would appreciate some advice
Thanks

ChiHai make decent motors. 
Not sure what speed your current 480 long is running at now, at 31K you might not see much of an increase in cycling speed, if any at all.
Being high torque though the trigger should be snappy. High torque motors make all their grunt right from the get go and are usually best suited to metal geared builds running big piston springs for high FPS.
Generally, RPM on them is usually lower than a high speed motor, which is faster but has less torque and is more suited to a less stressed build with high ROF as the priority.
Got a similar one of those for my ACR DMR BUSHMASTER and can confirm that with the rare earth magnets they have a shitonne of torque and decent amount of RPM @18000 under load on 7.4V without being too over the top on 11.1V 
Was running in an MK TACTICAL Alloy Gearbox though, as they do need something pretty solid to bolt onto, along with metal gears etc to match the output of these higher torque type motors.
Thanks gents, current RPS in that blaster is approx 17.
If I wanted to target around 22-24 rps, should I be looking at a motor that is faster than 31000 rpm?
Yes, faster motor but still need decent torque if you are running a heavy spring?
Can use a high RPM motor or swap gears to 16/13:1 with a high torque to increase ROF, but everything needs a bit of research/calculating to achieve your end goals of what exactly you are chasing from your blaster.
@RokSolid would be the best bloke to talk to regarding this topic, as I don’t have much experience with higher ROF builds, preferring the original old kerchunk kerchunk simulated ROF myself 
Don’t forget to check out the rated performance of each motor, where RPM is relevant to the Voltage, free spinning and under load speed performance differences.
Ok thanks. What I’m hoping to achieve is a small pop in performance without going over the top. If I had to start doing work to the gearbox then I’d probably leave it alone.
Yep… me too.

Yeah it’s pretty bad when looking to slow down ROF on certain blasters because they just sounded too fast for a particular model replica!
But the magazines hold more so let em hit 2krpm 
Sorry @Jug I somehow totally missed this thread!
Regarding the motor, I quite like them. They usually get about 21rps with standard 18:1 gears, they are a huge step up in torque compared to stock motors, so semi response will increase too.
I just rebuilt a mates SLR with one, it has 16:1 and gets 22rps, but runs a good responsive semi.
I also have one in a 13:1 build, which is a beast, running 25-26rps (can’t remember exactly)
In all instances, they do get hot with heavy use. But they do seem to just keep going.
ChiHai, make hundreds of different motors. It is overwhelming when looking at their full range. This one is good. I am considering a few to try soon, and have one coming that I haven’t used before. They always updating their range, which can lead to confusion, as some are similar, and some vastly different but look the almost the same!
Another good similar option for a slight boost in rps, but more torque is the 29k T238 brushed motor- Black version about $73 atm with conversion rate, and their shipping is usually 7-8 working days. If you want free shipping the code GBNOBODY will get it, otherwise if spending over $98 USD shipping is free and you can use the 8% off code offered in their mail list 
The T238, like the chihai super motor, gets warm with heavy use. But keeps going and is pretty good. Their 33k red version, is trying to be too quick imo and gets HOT, also gets about 26 rps on 18:1, I think the speed is being underrated by them. Much prefer the 29k black version.
Thanks @RokSolid 
The T238 you linked sounds exactly what I’m after, a small increase in torque and FPS without going OOT.
Anyway its on order with the free shipping link, I’ll be sure to post before and after results
They are a good motor. Will be a good increase in torque and responsiveness from stock, and should be a little faster too.
If you want more rate of fire down the track, changing gears to 16, 13, or 12:1 will get up to 30rps with the 12:1 gears so it gives you options
Good info thanks
I’ll try one first and if successful I’ll upgrade the other blasters in the collection
