Question:Determining equivalent brushed vs brushless motors for stock class.

[sam the man]

Hi guys

At our club we currently race a 23t stock class and are looking at introducing brushless to run alongside the brushed motors for the next year as a sort of integration period, thereafter we would like to make it a brushless only class.

Our dilemna comes in where what "stock" bl equipment to run now which will be on a par with it's brushed counterparts which can still be used the next year with "stock" settings switched off.

We currently run the tamiya 23t RZ/TZ motors and have been advised by one of the local importers to run any esc so long as it has "sprtsman" mode but to limit the kv of the motor as a tool to level out performance rather than going the "one make system" route, although he isn't against it. The other thing is, some of our racers already have esc's that have "sportsman" mode and don't want to spend extra cash on another esc.

Another question that keeps popping up is:
1. ""I would think a ESC locked would then limit the Kv rating to a certain value on the motor???

....so if someone has a fancy motor rated at 2600 compared to a 1900, under stock conditions the Kv value of 2600 is governed surely, the motor cant perform to its max. I mean its related to revs and that's what provides the performance???

If not....what then makes the sport mode equal across the board ??""

2. ""So...and I am sorry for a few dof Q's but I am doing some serious homework at the moment re Brushless....

If any set up is restricted to Sportsmode with light to indicate, does this mean is alters the Kv output of the motor??

If so...then does all, meaning different brands, have the same Kv rating when restricted.""

Any and all help will be greatly appreciated.
