Maybe we all need a refresher on how ROAR works:
Some company needs to submit a comprehensive, written proposal to ROAR. In the situation of changing the mod brushless rules, that proposal would then be sent to the entire brushless motor committee--consisting of reps from all the companies who manufacture or market BL motors aimed at ROAR-type racing.
Then all of those companies are given an opportunity to comment on the new proposal. At some point, the reps are required to vote and agree on the changes. Those changes are presented to the EXCOM of ROAR which then decides to accept, or reject the suggestions from the BL motor committee. If the new rule is accepted, then it is published by ROAR and included in the next rule-book.
On its own, ROAR does not just make random, new rules whenever it feels like it.
As far as I know, all BL companies that wanted to offer approved motors---even Trinity, Hacker and SpeedPassion---tooled up motors that would conform to the rules. Feigao, OEM motor maker to the world
, managed to convert whatever motors they were selling to approved versions.
