esc question for a HV setup.. (no novak, HighVoltage...)

[Serum]

The 2240 thread of Promod got me thinking.

I am thinking about buying a low kv 2240 and a high voltage speedo.

now here is the question;

If i use a mechanical brake, instead of the motorbrake, is it possible to use a speedcontroller that is ment to be put in a plane/boat?

Something like the Master 135-O by hacker.. 135A with a maxx of 32 cells.

Or the Master 77-O (30 cells 77Amps..)

The braking is a big stress for the speedo, and i am going to use a mechanical brake..
