advice on moving from highend brushed to brushless motor market.

[B3.is.King]

Basically I am toying with the idea of moving over to brushless system.

I am use to racing an running checkpoint 9t off road motors (or similar epic motors) with the blue and red springs on a 1/10th 2wd buggy. And to be honest with the check point motors they don’t normally need much maintenance until the 35 run mark, plus I quite enjoy the whole machining of the comms and such.

If I was in the future to move over to brushless in the future what type of spec motor would I need to match the performance of my checkpoints??
Also can you adjust the timings on the brushless systems?
Dose the braking compare to brushed motors?
Whereas on a tight and winey track if I had a fast motor I would just change silver brushes for copper ones to compensate... what can be done with brushless systems as I wouldn’t really want to be changing motors at every different track due to costs.

Any advice would be appreciated
