iii) In addition, the CD has the discretion to allow the following:
(a) An aftermarket motor that is a re-labeled and exact copy of any
approved motor.
(b) Any generational change of an approved motor, or a motor that
is used in a Ready To Run (RTR) offering from a manufacturer
that produces over 100 units of said offering, as long as there is
no more than a 5% increase in any of the following
manufacturers specifications as compared to any single
approved motor: Kv, maximum constant amperage rating,
mass, and MSRP.
(c) The race flyer shall list additional allowed motors for the event
By my reading of the rules, if the motor isn't on the "approved" list of motors, then it must meet A, B,
OR C...
The new Dynamite motors in the Pro Boat RTRs are new, and clearly don't meet "A".
The new Dynamite motors in the Pro Boat RTRs are also 61mm long, which exceeds the 5% rule for length, so they also don't meet "B".
Now, while I believe the INTENT was for "C" to be more of a "note" in regards to A and B, it READs as the third bullet; A third criteria to consider for allowance. As such, the CD of whatever "event" you are running must print a flyer identifying any additional motor allowances.
So, if your club has an upcoming race, and in the announcement (E-mail, etc.) for the race lists the additional motor allowances, then you would be allowed to run these, per the NAMBA rules as they are written.
