Let customers speak for us
from 132 reviewsThese gearmotors have been amazing for me. I use them in a way that nobody else should: as a meltybrain. 10 times per second these motors are accelerating hard and then braking hard in order to make by bot (Meltimizer) translate across the arena while spinning. And the Blitz Lites do it like its nothing. In one session of stress testing, they lasted for 14 minutes of hard driving before I lost a drive side - the reason I lost the drive side was because enough heat had built up and conducted down the shaft that the TPU in my cast wheels softened and let go of the hub. The motor still spun fine!
Specs:
Blitz Lite 2850 kV
6S LiHV
2.65" Vytaflex 45A cast wheels (HS-TPU interlocking with the Vytaflex and connecting to the hub from a foam wheel)
Flywoo Goku G45M 4-in-1 ESC
I can't attest to how they will stand up to direct hits to the wheels since my bot design and armor has prevented anyone from directly hitting the wheels yet. But I have been astounded by the capability of these little gearmotors. Highly recommended.
I use this for the weapon in my beetleweight eggbeater (2700KV motor). I have had zero issues with it so far. Stays very cool during combat. Highly recommended!
Great option for mounting the Blitz Lites. I had very little space and weight for motor mounts; these weigh nothing but certainly do not compromise strength. Having six holes allowed me to orient my wires however I wished.
None of my ESCs have a BEC, this board is a great choice. Works perfectly with the AFHDS 2A receiver I'm using. The switch also works very well. The board itself makes wiring so much easier.
Great ESC, it works perfectly with my Blitz Lite drive motors. I have yet to see one of these fail. Barely needs any tweaking when used for brushless drive. Highly recommended.
I used two of the 3800KV versions in my belt driven beetleweight eggbeater. In one fight I took a lot of abuse. The motors never failed and I was able to keep driving for the entire match. Great for pushing other robots around; a good balance of speed and torque for my bot. Works great with the JCR-RC 35A ESCs. I highly recommend these motors!
Fast shipping
These motors survived a near direct hit from a fearsome horizontal spinner with only a touch under 2 mm of TPU standing between them and the blade at the thinnest (your results may vary)
I have used these motors for three events spanning 12 fights and I have only needed to use 2 of the ones I bought, and that was because replacing an arm wholesale is easier than replacing the blade. The other 3 sit in a box waiting. Be sure to protect the phase wires and have some spare bearings, but this product is as good as you can ask for in a hubmotor at its size.
Great add-on worked and fit perfectly. Instructions were clear. I would buy it again.
Looking at the gearboxes I really appreciate the beefy internal gears and the 1/2in hex. With a bit of grease they run very smoothly and show no signs after wear after one tournament. I really like how reinforced the motor is with the cage. Normally with outrunners I worry about how the motors survive shock and wires rubbing against it, but with the cage it feels very solid. It is a little wider though so you have to adjust for that but overall solid. I wrote a little about my experience with the gearboxes alone here: https://teambonedead.com/2025/12/23/nhrl-grand-finals-2025/ and will write more about the full gearbox pair.
Really solid and lightweight! A little bit oversized, had to pass the file on each side of the hex only twice and it was a great fit.
We appreciate the fast fulfillment with ordering replacements parts to get our SSPKit ready for the next event!
I switched to using a PUPPY in my beetle back in March following a few fight losses where power switch failure got in the way of otherwise winnable matches. Gone are the days of snapped screws, busted resistors, stripped brass, and rounded out keyholes- I truly do not have to baby this switch like I've had to for others.
It's great to have another component that convinces me for sure that my robot will be doing exactly what I need it to when the match starts all the way to the finish.
As a builder with little experience in radio settings the fact that these ESCs have built in mixing and calibration is an amazing. My drive has so much more power and precision than before upgrading to them. Also I’m terrible at soldering so the fact there’s a pre-soldered upgrade option was also really helpful. I haven’t fought with a weka in the bot yet but I’ve done some test driving and it’s noticeably better than before.
