Will this motor fit a Tamiya hotshot? And is it quicker than the super sport motor?
Asked by Tim on 31st August 2016

It's a 550 size, so a little larger than your standard 540. We'd recommend sticking to a 540 size motor to avoid any fitment issues.

I believe the super sport motor is around 23T, so yes - a 12T motor would be much quicker, but you'd need to check that your speed controller could handle it.

Would this motor fit FTX carnage 2.0 and if so would it make much difference and would I need anything else to fit it many thanks
Asked by Matt on 19th January 2020

Yes it should fit the Carnage. It's 12T so will be an upgrade over the 15T stock motor, however the stock ESC won't handle that. You would want to upgrade the ESC to say HW30120201

Answered by: Ben @ Wheelspin Models

Could this be used in the HPI wheely king 4x4? and what would performance be roughly in mph?
Asked by Matthew on 27th July 2020

Yes, it's standard size so should fit that model.

Answered by: Ben @ Wheelspin Models

What’s the maximum RPM of this motor?
Asked by Matthew on 27th July 2020

Not quoted sorry

Answered by: Ben @ Wheelspin Models

Is this waterproof?
Asked by Matthew on 6th August 2020

Motors are inherently fine with water - but you must ensure they are thoroughly cleaned and dried after wet use

Answered by: Ben @ Wheelspin Models

Would this work well with a 2S LiPo in the HPI Wheely King 4x4 as well as off-road?
Asked by Matthew on 26th August 2020

Yes that should be OK

Answered by: Ben @ Wheelspin Models

Hi is this motor a suitable upgrade for a trx 4 sport to gain a bit more punch and top end speed.
Asked by Shane Morgan on 20th January 2021

It's the same size but lower turns, so yes will be quicker. I'd not run 3S however 

Answered by: Ben @ Wheelspin Models

Is there a heatsink that is compatible with this motor please.
Asked by Mr Antony Webber on 25th May 2021

HW86080120 or P-CC111400 should do the trick

Answered by: Ben @ Wheelspin Models

Will this make my maverick phantom xt quicker? It has a 550 15t motor
Asked by Ben on 20th March 2023

Yes this will increase the speed slightly.
