Description should provide more info for recommended applications. This motor is not for typical 1/8th scale off-road tracks, but for very large tracks with long straights. The torque is in the high rpm range, so using this on a short track will cause overheating. A $165 lesson learned.
I have been running this motor in my Tekno ET48 2.0 since March. TONS of power - despite my conservative gearing, this thing is so powerful it makes my ebuggy with 1900kv look silly. On my home track with a 170 ft front straight, there has not been a car or truck I could not gain on in power sections. Also, despite all the abuse I've given it (more on this later), it still seems to be running well. However, if I were to do it again, I'm not sure I would pick this motor. First, I found a motor fan to be pretty much a requirement, as I simply could not finish a 8 minute main before triggering thermal shutdown (which on my ESC is set at 227 degrees). I run a 14T pinion (which is the smallest you can fit unless you remove the center brace) so it's not like I've been running a crazy tall gearing. As if having to run a fan wasn't enough annoyance, even with one you will struggle with heat. For instance, despite yesterday being an unusually cool 71 degrees day, the motor came off the track at * 181 * degrees after 8 minutes. On most summer days you will be dancing closer to 200 degrees. It will tax your ESC and battery as well - my XR8 SCT hit 192 degrees and Protek 6000mAh 110 degrees yesterday. I am not expecting either to last very long. While not an apples to apples comparison, consider that on my ebuggy, with a 1900kv motor, the ESC doesn't even need a fan. So, a very powerful motor, albeit with limited appeal. Yes, you can drive conservatively to manage heat, but if you have to baby it, what's the point of running a motor this powerful in the first place?
Excellent quiet engine, the declared characteristics match!
Hobbywing is just rock solid. Yeah, there's issues with a product here or there but everyone has that. Their stuff is good looking, tough, delivers as promised, decently priced, easy to program and install and this motor is no different. Pulls hard, doesn't complain. I like it.
This is the perfect 1/8 truggy motor, has all the power one needs to be competitive at all causes, recommend to anyone!!!!
Reviewers largely praise the motor's power and performance, with several 5/5 owners describing it as strong, quiet and competitive in 1/8 truggy and buggy use. One owner using a Tekno ET48 2.0 reports strong power on a long straight but says a motor fan was needed to finish an 8-minute main without thermal shutdown, and that a 14T pinion was still hot. Another 3/5 reviewer says the motor overheated on a short track and suggests the listing should state recommended applications. Reviewers disagree on cooling: one reports it runs cool with 6400mAh packs and correct gearing. Gearing and track length appear to determine whether heat becomes a problem.
- + Strong power and torque
- + Quiet operation
- + Runs cool with correct gearing
- + Competitive in 1/8 truggy use
- − Overheating on short tracks
- − Needs a fan or careful gearing to avoid thermal shutdown
- − Listing lacks recommended application details
