I have bought the blitz which has a 15t firebolt and tell you one thing. This thing lasts ALLOT longer than and traxxas 12t 550 motor. And i have put this thing through hell. I have opened the motor and its very complicated. Its built very well. I've dropped the thing countless times and still kick-en. I gotten sand, mud, grass, and other outdoor things in and performance hasn't dropped a bit. It comes with very high torque and plenty on top end. Ive put this directly on a 3s lipo, and its just screams power. But the negavtive is that brushes aren't interchangeable. But this motor lasted me 6 months and im still on my first pair ( Original ) of brushes. And if it does die; its only a 15 fix
Bought two of these motors for the price and they both lasted a long time still have the last one I put in since I went to brushless. Way better then the stock motors in the slash. For the price you can't beat it!!! Strongly recommend is you have brushed!!!
I have been very impressed with this motor. It outperforms more expensive motors such as the traxxas 12 turn and actually performs as well as the reedy 30000 rpm 17 turn in my tc3, best brushed motor ive used.
Very poor quality of brushes, brushes VERY-VERY SOFT, my Titan dead with 3/4 of thinkness of brushes, this motor and 20T Saturn erased their brushes on the motor and dead. Running indoor carpet. Plus"+" brush was erased first. 5 motors were used by me, and 25 by another drivers.
Went through the original one in a normal time, but when I burned that one up, I purchased another one and it lasted about 15 battery charges. I called HPI to complain, and the service tech I spoke with said 15 batteries was all I should expect. Needless to say I decided to go brushless. Very disappointing.
Reviewers generally rate the HPI Sport 3 Firebolt 540 15T motor highly for its price, citing strong speed and torque and good durability in several reports, including use on 3S and 2S packs and in crawlers. Some owners say it outlasted cheaper brushed motors. Others report short lifespans, with one describing about 15 battery charges before failure and another blaming soft brushes that wore quickly on indoor carpet. Brushes are not interchangeable with other motors, which some reviewers noted as a drawback. Opinions diverge mainly on longevity, which appears to depend on gearing, surface and driving style. Nine reviews, several with unclear usage conditions.
