1/5th Brushless out of the box?!

[What's_nitro?]

I think this just became a serious conversation.

[Obeast44]

Heres a pic of the Redcat 1/5 Brushless 4wd Buggy thats in the works. Testing has already began, and I should have a proto in the coming months. I dont have alot of specifics like weight, battery compartment size or anything just yet. Roller weight should be in the 5-6kg range at most, I just hope they offer rollers to everyone. I PMed Patrick at CC about getting the mounting dimensions of the MMMXL so I could possibly have the buggy prepared for it to drop right in.



If you want more pics I can post them.

You guys can have the wheelies, id rather have on track performance :)

Badass, I want one. Looks like my lst just bigger. I am sure whith normal driving it will do fine, but have the power to do the fun tricks and stunts. I wonder what power system they are using...

Honestly you dont wanna know....HW 150a esc on 6s with a 1050kv motor...geared to the moon(55mph by the speed calc) so they fried it! Im begging them to sell it as a roller, considering ESC mounting, motor mounting and all that is easy as pie. Not to mention 90% of the people interested will already have the lipos, charger, motor, and ESC in mind that they wanna use, and just chuck the RTR stuff.

its all in how you drive it , those guys were just grabbing handfuls of throttle to show off we can all do that, i commend them though would like to see the price tag, i think i am going to do a 1/6 scale of my e-maxx why not everybody else is going big

If you read his post at the top of page 2 he seems to have some insider info or knows someone involved...

Lots of load on that motor, seems like they were trying to run it at lower rpms to match the gas motor's rpm band.

I think higher motor speed (30k plus) and some addl reduction is a must for 1/5 scale stuff. Unless you plan to run a 2230 neu you need the lower gearing to drop the crazy load and amp draw on the smaller motors. I can see a 1527 working nicely, running 10 or 12s and spinning 35k max with the truck geared for about 45mph. Some 5k 40c lipos would give decent runtimes at 10s or more.

Sounds like the new MMM hv ice omgwtfbbq esc with 4whl mech brakes running 12s lipo would be a nice setup, with a 700-800kv 1527. Might have to add some gear reduction, like what Dan Kershaw did with his baja conversion.

HV would be a requirement with 1/5 4wd, and a ligher electric specific chassis would be nice.

Lots of info in this thread, and a few more pics and vids :)

Plus I have a few pics that show the ESC and motor. I also have alot more pics in an album on my user profile on that site.
I dont see a way to have a mech brake setup without doing some custom modifications. I think 10s with ESC braking using the MMMXL omfgwtfbbq CC ESC will be very effective. I understand you wont have a front/rear bias, but it has a center spool instead of a diff. So its kind of a moot point :)
Im considering using a 2215 @ 750KV on 10s and gear it appropriately of course. If anyone has any questions regarding it, please feel free to PM me and I will try my best to get the answer for you. Bear in mind im just a regular guy like everyone else so they might not be willing to share all of the juicy details just yet.

That thing is amazing .. I'm going to order me a 120A ESC with a 5000KV motor on 4S ... and put it in my 1:1 !!
