Specifications

Genuine HPI quality spare part for easy maintenance and repairs.

Fits right into all HPI electric cars and trucks! The lower the number of turns, the more powerful the motor is - this motor is much more powerful and the Saturn 27T and 20T motors!

Note: Before purchasing this motor, you must make sure that your electronic speed controller (ESC) is capable of handling motors as powerful as 15-turn motors. ESCs that are not rated for powerful motors will be damaged and will need to be replaced. The #341 SC-15 Electronic Speed Control is able to power 15-turn motors, however the #340 EN-1 is not.

Questions & Answers

Real questions from real customers. Why not ask your own?
What voltage can these take and can I run them on a lipo?
Michael / 5th July 2023

These can run on 12v, but this will depend on what ESC you are using. Yes you can use lipo but again this depends on what ESC you are using.

Si @ Wheelspin Models
What’s the best esc to use with this motor? (HPI Firebolt - I want to avoid thermal shutdown and use 2s lipo) Thanks.
Steve Douglas / 13th October 2022

This would be fine HW30120201

Steve W @ Wheelspin Models
will this be faster than a 17t motor
Dominic / 11th January 2021

Yes this will be a little bit quicker. 

Anthony @ Wheelspin Models
Would this be compatible with my maverick strada mt
Ian / 28th December 2020

Yes that would work

Ben @ Wheelspin Models
Will this work with a Brushed FTX Carnage 2?
Mike / 27th September 2020

Yes that would work

Ben @ Wheelspin Models
Hi, can this motor handle 3S?
Ak / 25th August 2020

I'd say 2S is your max on these

Ben @ Wheelspin Models
How fast would this make the HPI Wheely King 4x4 go in mph?
Matthew / 8th July 2020

Near impossible to quote an exact speed, but it should be noticeably quicker than the stock 27T

Ben @ Wheelspin Models
Is this waterproof?
Matthew / 8th July 2020

Brushed motors are inherently water resistant and will be fine with the odd splash of water. Just be sure to clean and dry thoroughly after wet use.

Ben @ Wheelspin Models
Is the Firebolt 15T motor universal in terms of fitment. For example, will it fit a Schumacher CAT3000 with no modifications? Also, can you please advise on the motor body and shaft diameters? Thank you.
Roger Vagnarelli / 27th February 2018

Yes, it's a standard 540 sized motor as used in pretty much all 1:10 cars. It has standard 3.2mm shaft diameter.
