Crt.5 ext. pics

I already had the Mamba 5700 and Mike designed the chassis to fit the 4200 2s2p perfectly with the Max behind it. He did, however, put two nice long lines of mounting holes to make it an easy swap to other battery configurations; just won't have alot of room left behind standard size 4-6000 mah cells. I don't think I would want the added wieght of 3s for racing purposes but it would'nt hurt my feelings if there was an L motor available with a kv around 5500; the mamba gets a pretty good workout.

That looks awesome. I can't wait to see it.

We're heading down tomorrow (Wednesday) afternoon... just going to chill and help out with the track and get some practice in for a few days before the race. Looks like we'll be running in the same class (Open).. I think that's a first, right? Maybe not. Anyway, looks good, man. See you in the valley.

How are the temps with the 5700? I tried both the 4600 and 5700 and both (and the ESC) got too hot for me, even on 2s geared 12T. An L motor with a kv of 5500 would be around 4 turn. That would pull quite a bit of current! 3s lets you use a lower kv motor to get the same speed and is easier to get the total power...

I agree Brian. It might cost you a little weight on the truck to go 3s, but I think the amp draw reduction would be worth it. My CRT.5 is running on 3s and a 3019kv Hacker 8L and the MM and running really hard nothing even gets more than warm. Maybe 110 on the motor and esc.

looks great, i will be getting a chassis as well

I have'nt run with the Chassis and Truck tires yet. With the buggy rears and a 14 tooth pinion it would run upper 130s/motor, mid 140s to mid 150s/esc when I was really pushing it in 90 degree weather. With a little better throttle management and/or mid 70s evening temperatures I could keep both motor and esc 10-15 degrees cooler. I have a 13 on the new setup; hopefully it won't run too much hotter.
I certainly don't disagree with you or Hautz about the 3s/L motor being a better choice. It's a matter of what I had vs. how much more I could('nt) afford to spend.

So is this extended chassis availble throught RC monster now or is it coming soon?
Thanks,
