I haven't seen nor touched his controller, so I do not know yet.
I thought we did the estimate with you before.

Thank's artur for the heatsink update. Whats your opinion on the heat spreader for the quark, copper or aluminum ?. Artur how have you been ?.

You welcome!
For Quark:
- use stock alum housing as external heatsink
- replace both alum internal plates with brass

Challenge:
- very tight inside
- galvanics, is it a problem? :)
- soldering...

I just heard from the engineer and he is having some trouble with the software. This is what he asked me: "We need to know when the brake apply. For example, to what exactly position you turn the trigger will just free the motor and to what position you turn the trigger will apply the brake." I told him that the brake has to be proportional with the trigger and it should not be applied when the throttle is at neutral. I know there is the "ms" things and I have no clue what they mean and if they could help them at all. Any inputs will be appreciated.

My guess for "ms" is milliseconds. The transmitter sends out throttle pulses of 0-2ms long, depending upon the position of the trigger. 1ms is neutral. For airplane radios, I believe 0ms is neutral (since they don't have reverse).
