Personally I dont care about ROAR and if they approve LIPO or not. I am a basher not a racer and I am sure I am not in the minority.
I have a t4, lipo batteries, novak brushless 6.5, 7.5 and 10.5 with GTB- esc, and the fasst 2.4g radio w/reciever. I have a hell of a good time just running on the track, and I have no desire to race.
How ever I would like to see some improvements to the T4. With the motor and lipo the truck is very fast, but it breaks faster as well. I would like to see upgraded shocks, and with out a doubt stronger, more durable front A-Arms.
Just my .02 on the conversation.
