I was thinking about getting a Mamba 25/Sidewinder brushless combo and was wondering which motor would work best on our cars. 5400k, 6800k or 8000k, which is best? I'll be running on a 1/10 scale parking lot track most of the time.

5400 if you want to be safe and 6800 if you think you can keep up with the car. Both are scary fast in the MRS4 with 7volts.

MikeR, is your website having trouble? I can not get on.

Hello All,

This is the official announcement that the EXO3 pre order has begun! This is a very limited chassis release so get them while they are in stock!

Thanks,

Just poked around the pages and seems to be ok for me. You using firefox or the latest IE?

I am using IE.

You know what- my site is hosted by godaddy and it is down right now along with godaddy.com great!

Oh boy!!! I'm assuming that 150mm is better for longer tracks right?

Most cases yes. That's what I used at the HPI challenge. Only problem is 150mm bodies are hard to come by when you're talking about having to run an HPI body at a HPI event. The 140 bodies are so much better looking too but that's your call.

Hey Mike - so this new chassis cannot be switched back & forth between 140mm & 150mm??

Ya, I ended up butchering up a 140mm body to run in the challenge. I forgot that the wheel wells were pre cut and ended up with really big wheel wells.

Anybody using a 6800 mamba? I need help with pinion size, this is my first brushless motor.

I'll look at my motor tomorrow when I get into my Hobby pile - I was using a Tekin 6800 in my micro the last time, and I think I was plenty fast with my gearing

Just make sure you add some ballast on the chassis if you're planning on Lipo as well the mRS4 gets all "floaty" running the BL/Lipo combo

Start with a 10t and adjust from there by how hot the motor is.

thanks!
