so if a couple of clubs allowed the EX 13.5 novaks, or the Dragon nosram Bonded motors or even the NEW lrp budget setup's to race in the same class as brushed 27t
there be no problem with comparison ,bonded motors are a fair equivilent to brushed 27t ???
not looking for a perfecr match coz there's no such thing
even 27t brushed motors are vastly different to each other aswell as 19t
BL will get a much closer match between unit's then brushed motors could ever get

I have been running 13.5 pro at brentwood. (sintered) in a tc4 with older 3700's . granted i am probably not top 5 anyway and still working on car setup as well.
my speed is not far away from most others. so no great advantage. have not tried with really decent cells.
i think to insist that people only run bonded rotor is a bad road to take. asking for trouble. the idea of the ex series is to get your foot in the door of brushless, cheaper. the motor is then upgradeable to pro-spec (sintered) when your ready i.e. after your bonded rotor drops off in performance due to heat. the price of a sintered rotor will be less than a complete motor. so the financial outlay has been spread.
if you found yourself ballistic in comparison to the stock brigade the sportsman-like thing to do would be adjust gearing or batts to suit.
the advantage of the 13.5 brushless (sintered) is no skimming, heat issues,
if you need faster then there are plenty of faster motors and faster classes to run in!

another few question's 
will a 4.5t sintered Novak rotor fit in a 13.5 can ???
or fit in a 10.5 can
same with LRPx11 10.5t fit in a x11 3.5t can
reason
i could just buy one complete 13.5 motor & then buy different rotors to fit
IE;;10.5t & a 6.5t (cheaper this way
also why are the car BL motor's really expensive compared to airplane or helicopter BL sensored motors

its the can that determins the wind of the motor in brushless so you would have to buy one sintered rotor and the different cans to get the effect you want i think.

Okay
will a sintered rotor from a 3.5t fit into a 7.5t can & perform

It will fit as long as your 7.5T V. can has an oversized front bearing.

Well alocal club (WKRCC ) just had there comittee meeting & they have allowed 13.5 BL (sintered or bonded) in with 27t brushed
seperate Championship for both calss's but we all run together
19t brushed class has allowed the 10.5 BL in with them
so there are still 2 class's but with 4 championship's
this is not bad ,just to get the BL foot in the door to see what's what in the flesh & work on it from there
all class's are still 6 cell
some guy's are getting the novak EX range for like £150.00 speedo/motor
nosram budget motors @£35.00 one's are being looked at as is the LRP A.I speedo @£85.00 & £112.00 respectivley
see how it goes
thanks for the INfo
we now have 5 local clubs taking in Bl 13.5 to race
next step Li-Po
