I don't see sensorless taking over by any means (at least for racing). What I do see is the possibility to put sensors in a Delta wound motor. With the extra torque that deltas have, gearing them up produces an incredibly smooth powerband. Guaranteed starts and the power curve of a delta? THAT would be sweet.

I love my Mamba and Sidewinder systems so this is awesome news.

Now with timing being adjustable within the esc and rotors getting better all the time there is a HUGE gap between brushed and brushless stock.

Also, its not a matter of simply making a motor of the same kv...delta wound motors have a lot more torque so you would have to go to an even lower kv to compensate, thus making it impossible to get proper gearing in most cars.

+1 for roar making the motors legal for mod. Mod should always be more of an "open" type class as far as motors go. You can overpower any car with any type motor...
Well Castle could make a lower KV motor that would be equal to some of the other lets say 13.5 motors. Lets face it spec racing might use 13.5 motors built to the same rules but not all brands run equally. You have some fast and some slow so no different if Castle built something. It could be fast or it could be slow so it all depends on what a company wants to make.

Not sure on this, But you might be wrong, If you look at an identical wind in both wye and delta, you will see a 1.73 factor on the rpm's with the higher KV going to the delta. Going by that I would say that the wye should be the torquier motor and the delta would be smoother. Think of the KV difference like the difference between 2 and 4 stroke, lower kv should be torquier but lower RPM for the input. By my figures, you'd need a 3118kv motor to match the 21.5 (1800kv) power for power. Too bad the traxxas motor isn't going to be legal, its close in kv and can take a lot of gear

That's all I know.... and yes, Thomas did tell me to spread the word about this.

Sounds cool!

That may be true if certain things are held constant, but there are some key differences in current wye and delta winds for rc, the biggest one being rotor size. Looking at identical kv's (novak 7.5 @ 5800 and castle 5700) there is a big power despairity in favor of castles 5700.
A 3100 kv delta would be nowhere near a 21.5 in terms of power. The traxxas velineon is closer to a 10.5 (4200kv)


Hey ROAR...With castle motors roar legal, what other popular delts will be able to join the racing action?
