I know a couple of guys who race them and they commonly win (17.5) so I would imagine they are fine!

Mate I have a 17.5 one of the bullistorm motor I have used it over geared it to the shithouse and run timing at a maximum. I have a tekin rs pro speedie so I added all the turbo and boost and timing I could and it loved it.. Maybe a freak motor I couldnt tell ya but it went well... Just dont know how long it will last at those sort of settings but as for running it on basic settings and good gearing and timing I am sure for the cheap motor it will run for you well

Hope that helps

Default Bullistorm

I just bought one too and from the looks of it it appears to be similar to the epic based Trinity or Fantom brand with a different endbell for timing adjustment. I'll let you know how it runs. For the price it's wortha shot. I think we are saving money dealing with the manufacturer and no middleman. Right?

It does look close to a Duo1,

BUT...

-The wire diameter is smaller, has much higher inductance
-The stock rotor is 13mm
-rotor strength is 1680+ on a Trinity I-guass

For 1s applications... didn't work

On the dyno, didn't look good...

For 2s applications with 0 esc timing, so-so. Lacked top end and didn't have much off the turn. Just ran cool no matter how the gearing or timing was.

Just my 2 cents

Actually they look close to the GM Pro metal.They come with a 11,7mm rotor , they are realy fast but i don't know how long they last.I got a 5.5T but i have run it only for a couple of minutes so i haven't got the full picture.

I ordered 2 of them and neither of them "looked" like the pics.
The cans didn't have the vent holes and the endbells were solid.

I asked about it and no reply back.

Maybe I recieved a different version.
It did have all the timing hole options, a 13.0mm rotor that's VERY strong, and the can had very high inductance (40+ micro henerys) for a 17.5.

It's the same color, the can just didn't have vent holes and the endbells were solid pieces, no cut outs.

Oh well, add it to the pile..lol..

The motor in the pic is the 2nd one I got.

Rotor is 13.0mm and 1700+ on a Trinity I-guass.
The inductance is very high for a 17.5
