But no the HW motors are not Roar approved

Status: offline 		Well ROAR and IFMAR rules are usually just general guidelines in most cases. You don't need to use a ROAR or IFMAR approved part, you just have to use a part that meets their specs. The rulebooks don't show a list of approved motors... they just tell you what types of motors and turns are allowed in certain classes. If the motor has the turn rating written on the can, it should be fine, just ask the guys at your local track. You may have to worry about specifics if you ever decided to race in a sanctioned race, but local track stuff is usually really lenient.

The castle system is roar approved for mod 4x4 class.  Which is funny because in mod class everything goes including the ezrun SC system.

Status: offline 		straight out of the 2010 ROAR rule book:

"ROAR Stock, Super Stock and Spec motors must have a distinguishing feature
or mark not easily removed/altered on the stator stack or collection ring designating
the wind number."

Wind number, as in turns... and this is in the brushless section, page 49.

Then: "Modified motors must conform to technical specifications in Rule 8.4 above." which points to the stock/s.stock/spec section.

Says NOTHING about a KV rating, and when a rule book doesn't include a certain subject or specification, its illegal. I have not raced a ROAR event in years, long before brushless was really popular, but I do know many people who have gone to the nationals recently, none of them run KV motors.

When I have run in mod class nobody has said anything about rules except for batteries (2s-3s) and have seen lots of castle 4600/5700 motors and the occasional 7700kv in a on road class.

Because you kinda have to do that.

Yes, I do know what a stator stack is. Want me to draw you a picture? If this motor is 'ROAR approved', wouldn't they still list the turns or wind number in the description? Ya know... so you KNOW WHAT CLASS ITS LEGAL FOR?

Again... you would not need to worry about this unless you are getting into heavily sponsored races like regionals, nats, or world events, not little club races.

Considering 13.5 and 17.5 has a specific KV rating and the other classes do NOT it kinda narrows it down

You are proably gonna have to make some gearing changes.

The system you linked will work for what you are wanting but will not run with the tekins,kinetics,speed passion or HW esc's on the track.

I think you guys are missing the point of this system...

ROAR rules for SCT racing allow modified motors which is any motor with 1/8" shaft and 36.02mm x 53mm maximum dimensions.

Adding sensors would reduce the motor power by 30% because of the space required by the sensors they take away from the magnet and stator size. And besides, sensorless is now more powerful by a long way over sensored, and doesn't have any drawbacks (unless you want to drive at 1 mph...)

This motor is almost 300% more powerful than a 10.5 standard ROAR motor.

The ESC is a completely new design just fits in the Sidewinder case. This new SCT Sidewinder handles almost 50% more power than the old Sidewinder.

SO this is a 2S ROAR legal system that outperforms every ROAR legal system available today. AND it's priced at just $119.95.


And it's big brother is coming soon...

The Castle SC Sidewinder system is selling for $99.99 at my LHS. That is a smoking deal.

Like to have just the motor for say around 60-70 bucks  

Thread has gotten off topic I think.

Recap...

Xerun motor's no roar approval but most clubs will allow to use them just not at roar events.

Xerun esc you can use without issue

Roar rules are pretty much just made to favor a few electronics manufacturers who PAY for Roar's blessing.
