Newbie here I'm thinking of buying a brushless system I just what an opinion about the LRP AI Pro System pros and Cons

I have the 13.5 installed in my MF2. It's been very reliable with the only downside being no reverse lockout.

With no reverse lockout how is the braking and is there any accidental reverse on the tracks.

i dont own them but my buddies do have some problem with it. it kind of depend on type of radio. types of problem, it eliminates brake function when using AM and PCM FM.but it works well with at least FM HRS mode.

I don't think the braking is very consistent. Part of the time it feels like the rear tires are locked up and it gets a little squirrelly. Reverse can be used accidentally pretty easy if you're not careful. You just have to try to remember not to use it. It can be awful tempting though when you're nosed up against the pipe.

All in all, I think its a good system for bashing around, but not the best choice for racing.
