Not sure what you're referring to - but Roar has not banned sensorless systems. Sensorless motors and controllers are completely roar legal assuming they fall in to their other restrictions (rotor diameter, solder points, company name stamped on endbell, and most of all, rebuildable).

I'd be surprised if they came out with any "pro" 1/10th motors unless you considered castle-style neu 1509/1506 motors to fit that category. Though, who knows.

Yeah, because after 10,000 hours of running, I'm going to need some new bearings.

haha. Go brushless. Still, though... If you're serving your motor any kind of justice it's bound to get a little dirty once in a while. It''s nice to be able to flush any grime and extra oil away.

wrong, for example Tekin motor are rebuildable, with solde tabs and engraved endbell, they still failed ROAR approval why ?
They are delta wound,

ROAR legal motor must be Y wound motor, which is obviously more difficult to drive sensorless :/ ...

Why is Y obviously more difficult to drive sensorless?

You guys want to know a strange thing and why I don't like ROAR at all. The Trinity N60 and N40 are both Feigaos 380C and they seem to be Delta wound and they both are approved by ROAR. ROAR to me is like the FIA, but ROAR board seems to be getting their hands wet $$$$$$$ if you kow what I mean.

Thats quite a claim, If its true, thats a heck of a conspiracy towards other brushless manufacturers. Because its in the rules that Y winds are the only ones legal.

I just checked the roar rules and trinity, the only brushless motors trinity is saying are legal are the duo 10.5 and 17.5 motors

Look at the bottom and it says they are ROAR legal http://www.superiorhobbies.com/istar...&id=TRI0201!SH.

I opened my Feigao 380C http://www.rc-monster.com/proddetail...AO_380C&cat=20 and my Trinity N60 and they look the same. You guys be the judge. I can't find my camera and once I do I'll show you guys the inside of both.

You can't always tell if a motor is wye or delta by looking at the inside. The lehner 19xx series for example can be switched from wye to delta only by resoldering a few connections on the rear endbell. You don't need to alter the coils.

Yes and that's a plus for Lehner, but the minus is the price and that takes the 19xx out of it. It would be awesome to see a 19xx competing with the weak 200-300 watts motors. Man Lehner is missing a big share of the market if one stops to think about it.

Rotor is probably too big and MOST of the redline motors are probably delta wound (since most, but not all, are whole turns and do not have "half turns"). There's a few things that need to be met.

This is why I don't race... Too much politics and BS.
