Mechanical brakes - is it worth it??

[kalbien]

Hi there

I've been reading this forum for some time and there is a question of mechanical brakes appearing time to time.
I know conversions from Mike allow you to use mechanical brakes.

I am planning to use slipperential and Castle 2200 KV combo. and I am wondering, what are pros and cons about mechanical brakes.

Do you have any places to look for more info or some suggestions about this? I'm new to truggies so I really don't know if those are any good and worth the time to make them work...
