According to the brushless motors list posted at Roarracing.com, the Trinity 13mm are at the very bottom of the list of approved rotors.

Thanks on everything else though.

So it's legal now?
Hell yeah!

I'm actually quite surprised no one caught it before now. Apparently it has been approved for a year and a half. So it was legal in the D3.5 days as well...

They are approved for R.O.A.R. competition, but not in spec class.
They do have the inner spec shaft, but max diameter for spec class is 12.5mm

As for "riding that horse", that is my job.

It is my job to make my drivers equipment as fast as legally possible.
I stay on top of the rules and updates to do so.

Legal in general, or legal for the 17.5 turn stock classes? The approved list has lots of modified stuff on it.

The rule book hasn't been updated to reflect a 13mm rotor being approved for the 17.5 class.

Current rule as published for reference.


8.5.4.4.2 ROAR Spec Motors: External shaft diameter must be 0.125 inches (3.175mm). Only one piece, two pole Neodymium sintered, or Ferrite (Ceramic) magnetic rotors are permitted. The magnet length shall be 25.0 +/- 1.00mm not including any nonmagnetic balancing material. The magnet outside diameter shall be a maximum of 12.51 mm, no tolerance, for the entire length of the magnet. The shaft outside diameter, where the magnet is mounted, shall be 7.25 +/- 0.150mm for the entire length of the magnet. This dimension must be measurable without destroying the rotor.

Sorry, I didn't mean that as an insult. I know a lot of people repeat the same information time and time again without doing research.

Thank you for the source. My question is this...

If you are in a class that is designated "Sportsman Modified Short Course" with no motor specifically called out, does that mean this 13mm rotor would be legal?

If not, in what instance would they be legal?

Indeed. I have only heard good things about Fantom Ion motors. When I bought my D4's, the Fantom Ion V5 was on the short list of motors I was going to get, but couldn't swing the difference in price considering I was buying 4 motors at once.

No worries, I just wanted to make sure you understood where I was coming from.

As for your sc class, it would be legal in a modified class.

The Fantom spec models are within a couple dollars of the base Trinity models.
We now offer a spec max version that includes the 12.5mm Ht rotor at a competitive price.
When you start adding tuning options is where the price goes up.

That is a question for the track you race at. Everyone around the world will not have the same answer.

I'm not up much on Short Course rules, but if we are talking ROAR I believe it depends if it's 2wd or 4wd class. 2wd is standard modified rules. 4wd can use the 550 sized 2 pole motors per section 8.6. As mentioned club tracks may have other rules.

Again all to the best of my admittedly limited knowledge about the classes. Hopefully someone will call me out if incorrect.

i'm 99% sure that the 13mm rotor would be fine. you're running modified which should mean that anything goes. if your track STRICTLY adheres to ROAR rules (which very few tracks do), then i'm not sure. it really wouldn't be much of an issue at a ROAR race. if you run a 10.5 and you think the 13mm rotor would be better, just throw in an 8.5 and call it a day.

Ok correct me if I'm wrong but is this motor designed for 1s oval cars?

D4 1s Short Stack Spec Maxilla

http://www.trinityrc.net/shop/index....product_id=705

If so how would it work in a 2wd b5m buggy? I have heard these motors are ridiculously fast. Other wise I was gonna get this certified motor

http://www.trinityrc.net/shop/index....product_id=677.

Just wondering as 150 is a lot for a motor but I know they are nice. Any info is appriciated

elex300 01-15-2015 05:44 PM

You can run it on 2s as well.

They have an optimal range in which it should fall in.

I never got any paper work with my d4 17.5 can someone post what it says or formula to figure timing or is it based off of fdr?

racer888 01-15-2015 06:28 PM

Any thing special i need to do if my timing screwswere left loose and came out to make sure timing is still reading correctly or am i just screwed and need new motor?
