Another CORR conversion - RC-Monster Forums

Shark413 · **Another CORR conversion -** 11.06.2008, 05:46 PM

Well I just finished my Slayer to PE Revo brushless conversion so it was time to move on to something new. I owned both a Slash and Slayer, and I really liked the CORR truck concept. The Slash was fun but a little too slow for my taste, the Slayer was faster, but didn't handle as well as it should and it was nitro. The new Associated SC8 looks better but I already had a spare 1/8 scale roller sitting on the shelf so I decided that I would build a CORR style truck based on a 1/8 Kyosho Kanai nitro buggy. This buggy was previous converted to brushless, so the motor mount/battery tray was already in place. I bought a Proline Hardcore body and trimmed it to fit on the buggy chassis. I removed the 10mm offset hubs and replaced with standard no offset hubs. I added Ofna wheels/tires. Since the truck no longer had a rear wing and most of the impacts would be absorbed thru the body I wanted to retain the wide mounting of the Slash body mounts, plus they were made of some pretty tough plastic which would help the body absorb any crash damage. I wanted to mount them to the shock towers for a good strong mount, so I made some simple aluminum brackets, attached the Slash mounts to them and bolted them to the shock towers. The body mounts are both adjustable for height and pretty cheap to replace if they break. Next step, I will start work on the front bumper and nerf bars.

NICE!!!...i was going to convert my other 8ight roller (which i just converted into a MT or mini muggy type truck) into a CORR truck but decided to get the sc8 and convert it to brushless instead...Your CORR truck is going to look nice though..

Hootie, thanks. The SC8 looks really nice but it is pretty pricey. I do hope to get some of those associated wheel/tires to use on my conversion. It's really hard right now to find CORR style wheels/tires that fit on a 1/8 buggy (17mm hub).

That does look nice! Any plans to add bumpers?

Also, when I made my CORR, I was concerned about attaching the body mounts to the towers. I reluctantly used the tower in the rear, but it attaches fairly low to help reduce the strain. I am curious how the towers stand up to crashes. But, I suppose not too many are as bad a driver as I am. Yes, I've taken large jumps just to land smack dab on the lid!

lol, I guess I missed that.

on horizonhobby.com they have the wheels and body on back order and i think it says mid-november so at least you won't have to wait too long however, the pre-painted and decaled body costs $63.00 but the clear body costs $45 and for 4 wheels it costs $50 a pair....so its either going to be $163 dollars spent or $145....I think the wheels and body are waaaaaay overpriced..

Great looking conversion so far! I look forward to completion. I feel converting a Jammin x1-cr in my future, unless my 18t sells soon. :)

BrianG, yes I do plan on adding bumpers. I have custom skids on the bottom of the chassis front and back which bolt on using the diff screws. Right now those skids end right at the front of the chassis, I plan making another set and extending them about an inch and angling them up slightly. The Slash bumper can then be mounted to this extenstion. I will provide pictures when I actually start working on it. As far as the body mounting to the shock towers, well they are after market towers and much stronger than stock. I feel that between the extra strength, the additional flex from the stock Slash plastic body mounts and the larger lexan Corr body should help absorb any crash damage. I also picked the shock tower as a mount because the stock buggy mount consist of a single small point on top of the steering plate. I could have used this as a mount point but I felt a single small point, which ok for a smaller/lighter buggy body would not be strong enough for the larger Corr body. We will see, still a work in progress..

Actually after looking at the mounts I am not sure the Slash parts will hold up. The Slash is a much lighter vehicle. I will run it with the Slash mounts to see how they hold up, and if they break too easily I may have to make some custom mounts.

Looks very nice.

I was going to work on the front bumper but I found out I was out of the aluminum stock I needed so I worked on the chassis and battery tray instead. I cut a short piece of aluminum stock and drilled and countersunk the holes. This attaches to the center diff mount and serves as a brace and a place to hold the rx and ESC. I was going to run it without the mud guards, but decided to install them anyways. The battery tray is one that I have been using in all my conversions and has worked very well. It is pretty simple but effective, I have never lost a battery and it can hold the longer packs with no problem. I use either CF or aluminum as the base, cut to fit on the chassis. I then add a small stop on the side near the spur, this keeps the battery from contacting the gear in a hard crash. I will add heavy duty straps and most importantly HD velcro on the tray/battery. The straps hold the battery inplace and the velcro keeps the battery from sliding around. Since there are no walls many types of batteries will fit. I need to add padding to the stop and install the straps. The tray is then bolted to the chassis with two M4 screws, I try to use the exisiting holes in the chassis. Either rubber washers or a small rubber pad rest under the tray to raise it slightly to clear the chassis curve and also acts as padding.

mmmmm carbon fiber :)

Well I got a little more done tonight. Finished the battery tray, added the straps, padding, velcro and bolted the tray to the chassis. The straps are held down using steel washers that have a rubber pad bonded to it, this setup holds the strap but the rubber pad prevents the washer from cutting into the velcro. I have a picture showing how a 4S NeuEnergy lipo fits and another showing how a Zippy 4S also fits, with the Neu being fatter and the Zippy being much longer. They both fit with no problems.

3M dual lock Velcro on the battery and tray keeps the battery from sliding around.

Very Nice! Great looking build.
