When I talk about that it is the power band and efficiency. That power band is to suit the track, car and your driving style. Most indoor carpet tracks require more torque and top speed is usually only important on a single long straight (I build a lot of layouts and this is common). So having the car jump corner to corner is the goal. Make up .5 in the infield and give up .1 on the long straight is a win. Try to get both. Trying to build for max power and efficiency is a balancing act. Yesterday I ran in WGTR which uses open ROAR 17.5. Our track is a 90x40 box. Between the two motors I ran the highest timing was 35 deg. The car wasn't the fastest on the straight but close. It was a rocket thru the infield. TQ by a lap and the win by the same.
A outdoor track would probably set up a motor with a higher power band but maybe I would just gear and set the esc for less punch, not sure as I haven't done that in years.

I will add a comment to that statement. I can't tell you how many times I have heard "they are killing me on the straightaway". Might be a slight gauge, but how does it feel in the infield!

They pass tech because the are legal. Per Robk (Roar Technical Director) "Since it's basically impossible to identify a "premium" motor once you take it out of the box, they are legal. As you said, they just use top percentage legal parts. The only problem is some companies are going beyond the legal MSRP, but that is a ROAR problem, not a racer problem."
Certified Trinities are no different than buying a motor with a "tuning" service such a rotorRon.

Certified Trinity motors have a different endbell which is clearly recognisable.

Which can easily be swapped. Black, blue, orange, pink. It has no bearing on performance.

And yet it has the word "certified" stamped on it, making it clear it was from a motor that breaks the price rule. That's why one of the clubs near me will fail a motor at Tech if it has a certified endbell. If you replace the endbell with a standard one then it'll pass.

What a bunch of Baloney. One certified - rotor Rotor or any motor guy! You guys are funny complaining about nothing you can't do yourself with little effort. Each batch of motors are different. Your driving ablility - chassis set up and finely driving ability and consentration The only time the straightaway is important is Drag racing.
Plus the biggest problem now is ROAR has NOT UPDATED there rulebook on anything for YEARS! .

I think I will follow the rules clarification of the ROAR Technical Director over local rules at a track in a country that ROAR has no jurisdiction. It makes no sense to ban a motor for costing too much, when you can pay even more (new end bell and steel screws) to make it legal.

It's literally written in the ROAR rule book that a motor is not legal if it costs too much.

There's no ambiguity here. Trinity released a version of a specific motor above the maximum listed value. According to this clause, that means the approval for that motor should be revoked. The only reason ROAR haven't done so is because the last time they revoked a Trinity motor (D3.5 I believe), Trinity sued them. In lieu of ROAR explicitly revoking approval, this club is enforcing this clause themselves.

Where is the clarification from the ROAR technical director? It's not published on their rule book or website.

so buy a certified and change the endbell with the stock one lol, until roar decides to enforce all rules like the charging amp rating why bother with a price tag , either enforce all rules or none at all

Does your track ban every rotor ron tuned motor? Or any motor with upgrades that exceeds the max MSRP?


It's not posted anywhere .. But how often does ROAR update things?

Well, Rob's clarification got it wrong because it's not just cherry picked top percentage parts, it uses different parts that are easily identifiable. As that's a private message with factual errors, it's not a published clarification from the ROAR organisation.

The only part that is different is the color of the end plate. If your organization is literally banning motors with a different color end plate they need to get a life.
From the ROAR rules

THERE IS NO PERFORMANCE BENEFIT FROM THE COLOR OF END-PLATE.

Here is the thing. You can

1. Have your own track rules. Who cares but they are home rules so they do not apply elsewhere.
2. Have your country's governing RC body have there own rules
3. Follow the ROAR rules... which have NOT revoked the legality of the motor. It is up to ROAR to determine if the motor is legal. They know there is a variant out there that cost more than the arbitrary $150 and they have chosen NOT to revoke it. Therefore it is legal.

I really don't understand what your track is trying to accomplish. They are trying to ban a motor that cost too much? But it is perfectly OK to buy a $499 Motolyser and a $325 Magnalyser Rotor Checker and 10 Team SPEC motors $1149.90 and cherry pick the best Stators, rotors and sensor boards. Then throw in another $20+ on ceramic bearings. But I can't pay Trinity an extra $50 to do the same service (Which comes with the legal ceramic bearings) So it's really only $30
The other screwy thing is that your track would have been fine with a certified motor if they just would have not included the ceramic bearings and charged $15 less.

Generally one should not write/create rules that you are unable or unwilling to enforce.

I would think that the cost of the standard version of any motor would come into play with any motor. Not tuned/select part versions which is all these "Certified" are. Doesn't matter if it is the supplier or someone after market that does it. That situation can't be policed.
