Hi, I came from a nitro background so I was looking for a mech brake setup. When I started there were no kits that allowed mech brakes so I converted a Kyosho ST-RR myself and retained the mech brakes. The truggy was great and for me the mech brakes is what I felt comfortable with. This year I decided to try a Losi 8igth-T 2.0 and at first I went with the Losi kit and motor brake. The motor brakes worked great and it felt comparable to my Kyosho, lap times were almost identical. After a few months with the motor brake setup I decided I wanted to go back to mech brakes to reduce the load on my electronics and to allow brake bias. So I picked up an Tekno kit, which I have been using for about a month. The Tekno kit is great, the bias control is a plus and hopefully my electronics will hold up better when summer comes around and I see 100+ temps here in SoCal. So I have used motor and mech brakes and they both work fine, both setups have pros and cons, it's all about preference and what works for you.
