Quick test of 3 of the motors I had lying around. Just wanted to see if the advertised RPM aligned with the reading I was getting with my tachometer. Hardly scientific. Don't read too much into the results as some motors have a +/- 10% margin in their no-load RPM. Lot of factors at play. If someone else with a better understanding on motors can add to my knowledge please feel free to post a comment.
Greatly Appreciated as always! I tried some of the earlier Brushless motors and didn't get on with them much, but have been eyeing up the T238 and their newer blue can one that you test here. I have one of the older Solinks (Blue can "medium speed") which wasn't great, so good to see they've improved with the ones tested here.
Thanks, glad it helps. My Solink test motor has been pretty decent so far, only around 5k, was impressed with it being right on the correct RPM. Plan is to do a 5000 continuous shot test next and see how each motor holds up, record the temp of the motor etc.
KV rating is widely used with Brushless motor, indicates the rpm per volt applied. s in that case 2500kv*10v= 25k rpm. thanks for the great video, the only thing i'd suggest is to use a current meter in line to measure the voltage under load (small load roughly 2 amps when unloaded) and calculate the Kv of the motor. KV is the what we are really interested in because based on battery capacity and C rate will have voltage sag that will cause the motor to be slower; e.g small stick lipos will sag way more than a big brick, causing less output RPM. hope it make sense.

A small but useful difference of the Solink is it's shorter, so its alot easier to wire it in different kinds of grips. And while having a shorter rotor and stator it still keep up the rpm and torque with the others.
@@xtairsoft you can simply compare the motors and see the solink main body is shorter? And when you put it into the same AEG the ROF is still comparable as a normal sized brushless of same RPM.
@@wyz2285 I actually think the t238 motor is shorter than the solink. I have the solink v5 and the end bell design makes it longer than the t238. The solink lite motor looks visually longer than the solink v5 and the t238. Edit: (I have 2 t238 motors as well to confirm the size)
@@HikaruSwift17 The lite is shorter than any other brushless (not talking about full length, just where the wire plugs are, where some grip plate has less space for wires and this helps). You can also see in the Wyshtech's video where he compares Solink and T238
They are programmed at that RPM but they can be pumped higher than that, some manufacturers say the MAX Rpm for some are at or over 100k, which means it can reach that amount but not recommended (voids warranty)
What a let down the warhead is ,recently picked up some ahtech infinity adjustable brushless motors, same manufacturer as the T238's just different brand and significantly cheaper than the T238 adjustable motors actually they cost me the same as what i paid for the 37k T238 QRBLS brushless motor
@xtairsoft no idea tbh ,i had no idea that they were from the same manufacturer till i just happened to order a 48.5k adjustable after using the 37k QRBLS and was so happy with it and mentioned it to someone and they informed me that they were the same as the T238 so i thought stuff it order another one and a 39k version.

Where did you find the stats for that? I'd be interested in seeing. Was that for the Solink Lite?

How would you go about juicing one right up and not worried about warranty
@drewmurray6480 use a pwm or microcomputer

One thing to keep in mind is warranty on BL motors, do ahtech have a good repair service route?
