1/5 Scale Brushless MCD RR V4 Prototype
 

Saw this and having an MCD gasser here, was very intrigued since at heart, I am an electric man. :whistle:

Had contacted MCD awhile ago and from what they said looks like end of 2012 they are thinking of having something ready.

Since the MCD is not heavy like the Losi, they probably don't need as much to get stuff moving around sufficiently, probably an 8S lipo setup at most and that Castle XL ESC could work out, current shown setup is dual 3S lipos.

Hopefully they don't go with a killer price.

here are some pics:

I doubt MCD is going to stick with that dual motor, dual esc setup. When that setup was shown Castle had just taken the wraps off of their XL esc and 2028 motor. Theyre probably developing a single motor setup and gauging interest hence the delay. I'd contact Mike to see if he could use your MCD as a prototype or make a one off for you.

Another option is making something yourself. Search rc-m for Redcat conversions. They use a similar drivetrain layout and it might give you some ideas.

not sure, this was shown again at a recent toy fair using Tekin electronics.

Dual brushless set up will always get the WOW factor.

I have an MCD too, I've been waiting for this for ever....

If Mike is up for making a setup for an MCD, I'm willing to have him use my car for a template.

Are you up for it Mike?

I would be interested for sure. I am quite sure his conversion would come in at a price significantly less than what MCD will charge, which usually is an arm, leg, first born ... :)

Do want. Though I could use a single motor setup just as easily.

With how the current layout is of the gas version:

It could potentially be more involved than just a simple motor mount.

I really wonder how much RCMonster-Mike could run with it though, a nice clean chassis, and do his trick layout for 8S setup (dual 4S).

People think we are crazy for wanting 1/5 gassers as electrics, but I think it could help bring even more people into the scale just because you can now run the vehicles in areas where the noise isn't welcome.


I also wonder based on how they have the MCD conversion layout if they are thinking of doing a fluid filled center diff as there is a lot of room there with that gear in the pics.

A conversion for that does not look hard at all. Looks almost the same as the RedCat Rampage MTs. The hardest thing to make is the collet that connects the motor to the shaft.
Someone with good machining skills could definitely make a much nicer looking one that I made..

Very nice aqwut, that is exactly what I need!!! :)

Do you think the singel bearing is enough for the top gear?

Have you ran it yet?

If there is any design , I hope its a simple spur and pinion combo , exactly whats in 1/8 scale e-buggys. I converted my redcat like this and the simplicy makes it worth it . However my metal work is frigging ugly . Waiting for Mike to hook a sick piece. I gather the mcd and the redcat part would be exactly the same .

I would like the simpler design too. What MCD is doing on there setup other than the dual motor thing looks like it will put a center diff / pinion combo there.

i hope it made for a castle 2028 not dual motor

A simple center diff (or spool) and motor mount is the way to go. No offense to your fine work Aqwut, but the extra gears used to install a gasser just don't seem necessary for electric use.

In the photo at the start of this thread, looks like MCD is going with a center spool. The Redcat Rampage XBE also uses a spool. I'm curious to see how converted Losi 5ive-Ts make out with center diff temperatures in the long run.

Mike was also going to look at a CD conversion for the XBE...

Intent was to use a Baja diff.

I agree with the diff temps, my brushless 5ive diff gets pretty warm on 12s and the end of my drive shafts are turning blue!!

^^ Exactly what I was concerned about with such a large vehicle being hauled around with an electric motor and the inherent torque involved. All of my larger vehicles that use center diffs have this issue. To keep the diff from unloading, almost putty-like fluid is necessary. At the same time, grinding that stuff around in a diff causes incredible heat build-up.

Arct1k: I'll be curious to see what the outcome with that proposal. Stronger gears (from a baja rear diff, I presume) while more durable to withstand the stresses and heat involved, isn't exactly a solution in my opinion.

Non taken, I like to keep things stock as possible for ease of parts replacement. Plus, using a big motor you would need support for back end bell as well. If I had the machining skills, I would have done it different. :neutral:

Xb-e mount and a rampage mount would be welcomed .

The Losi gets hot largely due to the angle on the shafts - same thing happens on the 1/8 buggy and truggy. The diff helps handling on a track, though.
I do plan on making a mount and CD setup for the rampage xb-e in the near future. I will likely use a 3rd rampage stock diff with a custom gear and rear shaft. The Baja diff is a possibility as well, but would require custom diff outputs and spur as well.

Mike,

Any interest in making a set up for the MCD?

I would gladly make a conversion for the MCD.

What is the best way to contact you to get this project going?

You can use my truck if you wish for a template.

Email or PM for contact. I will definately need a vehicle to convert. :)

I think this is the best motor mount ever made, i'm biased of course:lol: http://i578.photobucket.com/albums/s...a/DSC01337.jpg http://i578.photobucket.com/albums/s...a/DSC01348.jpg

Shipped off the MCD roller to Mike.

:)

looking forward to what you come up with.

+1^^^

any interest in making other parts as well?

So, did it get there? Excited to see what he can come up with.

Yes, the truck made it to Mike. He has a couple of projects ahead of this one, but I'm sure he will keep us all posted.

good stuff. I actually got some lipos coming that i may just use for this based on what he is able to come up with.

forgot to ask this, but what kind of lipo setup were you looking to use?

open to suggestions regarding the battery box - drawing some on this now and hopefully can have something cut next week. :-)

I think for me personally, the main thing I like is if the trays have a sufficiently high front potion of the wall so that softcased packs don't shift as much. For hardcase I though I liked your previous trays I used in 1/8 electric.

Do you have any preliminary info on the layout you are going with?

Excited to see what you come up with!

Heck, would love to see more parts from you for the MCD in general as the standard MCD hop up parts are super expensive.

I dont see mike changing his basic tray design - A little velcro in the bottom stops the soft case batteries sliding.

not so much the actual battery sliding (i had no issues with that used weather stripping to snug everything up), but the individual cells in the shrinkwrap. What I saw was the basically it doing one of these:
_____
FRONT \ _____ \ REAR

it never really affected anything, and the conversion I had from him was good (RC8T). I just noticed how I liked the Hyper 9E tray I had when I got one in as the front wall was high enough to prevent this and figured I'd throw that out there if he was taking suggestions.

My battery trays are machined, not molded - height is limited by material thickness and tool length. That said, it is fairly easy to install a stop in the front of the tray for tall batteries.

Ahh I've never had cells slide over themselves...
