Another MBX6T Race Build.

[itbvolks]

Well, based on the current performance and recent development of brushless setups along with the quality conversions being offered today I decided it was time to get back to racing. I've been away from racing for several years now (~5'ish) so it was refreshing to see where things have come. Coming from a custom hyper7 extended, UE VBS/Racer-X setup years ago it was also nice to see the quality kit Mugen has put together. Very impressive indeed.

So based on my plans to build a racer I went with the mbx6t, RCM brushless conversion, Slipperential, Tekin RX8/1700kw truggy setup, lightweight driveline components, AKA's (cityblocks), etc.

Right now I'm trying to decide on batts. Planning on going with Hyperions but not sure on capacity or cell count. Originally I based the motor size on a 5S app for racing. I'd like smooth power with something in reserve without really overpowering the chassis/track. I'm thinking 5S is where I want to be for this app (shooting for 9'ish lb truck rtr).

The other concern is capacity. For a race setup, 2x-things to consider. Capacity and weight (for me anyway). I'm planning on having to run with the Nitro guys so a batt change will be in the cards for me. That being said, I don't want to stuff 6k worth of capacity into the truck due to weight.

Thinking 3000-4000 is where I want to be. Based on the specs from Hyperion, looks like roughly a 4.86oz savings from the 5k to the 4200mah setup (5S). Going down to the 3300mah setup saves me an additional 3.56oz and the 3000mah setup is another 1.41oz lighter still. Assuming the heats are ~5min plus warm up and additional lap and mains are in the 15-20min range, what are you guys who race running?

Pics to come tonight.
