I get where you are coming from but could there be a flipside to this. What I mean is you could go in the opposite direction with this and make a really low wound motor in mass (To get the cost down, economies of scale etc..) and use the software to soften it to matching charateristics of softer motors. Then everyone would only need to buy one speed contoller and motor and use the software to define class or power requirment. Just a thought.

here's another one to throw in the pot we run the smallest pinions we can get on our 410s 17t and 18t pinions yet we are quicker down the straight than most cars so do pinions make a difference any more with these escs?:confused:

Tish - Thats quite common. Brushless has so much torque it can pull really big gearings and everything looks good, but if you drop the gearing and let the motor rev instead you get just as much performance.
Pinions aren't quite irrelevant, but the power band for a good brushless is so big that you can run a range of sizes without much difference.

Actually thats the real message here - modern systems can offer all the power you'll ever want in a single package and you can tune to your needs. How you get there doesn't matter because when we can only use 80% of the potential anyway you don't need the most efficient way.....

Oomph
 
If anyone is finding they are lacking oomph with boosted motors I would recommend to try out running with no turbo at all on the esc as the quickest way to heat everything up is for the unit to be applying turbo in an unsuitable rev range ( think flooring your real life road car in 4th gear at 10mph) and run lot's of boost only ,an example for 13.5 ...
Boost start rpm 4000rpm
Turbo timing 0deg
Boost 40deg of a possible 64deg
Fdr 6.00fdr
Don't forget brushless is opposite to brushed , you will get more oomph out the corners with a bigger pinion not smaller
I have been playing with the hobbywing stuff for a few years now but it was not until I speed ran it off track that I saw how far it could go
The latest hobbywing download is now out, ver 3.2 which contains supercharged,mod and blinky,
