can you make a video showing us how the 454's do on this rig? please?

my dad has some 7t cobalt's on his killer krawler...it just plain RIPS!!!! it's a power house for sure! nice smooth, slow start-ups...but will ride a wheelie if you punch it...amazing motors!

it's making me think some 454's like what you have would really really be nice on a 2.2?

I'm really liking your build..nice job.

So I headed for my favorite local spot--a place I have spent countless hours with my shafty. So this gave me something to guage the rig on. Well I was indeed impressed--but its going to take some getting used to with the clod stall. But I was able to make every line I had with my shafty, granted a couple I had to work harder--but that might have been because I do indeed have too much weight in my wheels..

I will have to say I am impressed with the wheel speed I am getting with the 2 cell lipos I am running..

Now one thing I did notice and I am not 100% sure this is normal. But when you are in dig--you don't have the power you do when in 4 wheel drive..

Well I had to quit when I found one screw missing from my knuckle and put a slight kink in my servo horn and also the bolt that holds the tire rod/draglink on.

But I did shoot some video and will try and get something thrown together.

They are VERY smooth motors. I have not had a brushed motor in a long time (novak goat fan) and I was really impressed with not only how smooth they are--but how fast they zinged up with a 2 cell lipo. I think you should do em. I do have some video to do tonight if I get time.

How warm did they get Mike?

I didn't have my heat gun--but I could still touch them. They did get warm--but I think the motor on my goat used to get hotter..

Good to know.
Getting used to the stall is gonna be fun, after being used to having all 4 pulling until you engage dig for so long.

But, I'm sure you'll figure out how to use it to your advantage soon enough....

After watching you drive yours--I am sure I can learn --granted your a hard act to follow

I threw a little video of the rigs first trip out

Definately, lose some weight in the wheels. I'm running VP Pro Comps with no weights in the rear and 4 bullet weights in each front. So far this weight balance has give me the best results.

As for the knuckle bolt coming loose, thread lock is your friend. Did you locktite everything before assembling the rig? If not, I highly recommend taking the axles completely apart and thread lock every screw. The knuckles need particular attention. I used blue for everything, but I still check the knuckle screwes after every run, applying thread lock if they are loose at all. You may even want to use red locktite on the knuckle screws.

can you load a version of that vid with no sound?

I wanna hear those motors...not soft hits from the 80's.....

thanks

crawlinghulls · 08-02-2009, 03:10 PM

Wondering what the wheel speed is with those motors? Could be just the ticket.

crash · 08-02-2009, 05:35 PM

ok ok--how about I make a video with some wheelo speed

Ya ya. I can always bring mine out to compare. I am runnin HH 35 turns on 3 cell. But I wanna check those out 2. Nice job so far. Lookin good.

I have gotten a bunch of requests for how much wheel speed you can get out of these motors.

2 cell lipo, front pinion 13t and rear 11t

crash · 08-03-2009, 02:55 PM

Ok so I am still tweeking it. I knew I had too much weight in my wheels. Here is how much I pulled out of all 4.

11.7 oz

The rears are now at 7.8oz

The fronts are now at 11.4oz

crash · 08-03-2009, 03:03 PM

So one thing I wanted to do was give some motor protection. Well I looked at lonewolfs axle shield--but I just don't feel you need to have a full skid on the axle--plus you loose ground clearance and I have seen these axles just slide over rocks anyways.... So I had gotten a few ideas from RCC. Well the wife came home with a new container and I was sitting here looking at the lid--well I got a ll ninja like and swiped it,lol

Well the material feels perfect....

Now came the hard part--making it round and of course I aint got no heat gun. But I do have a torch nozzel for sweating copper pipe.

So I cut it into 2" wide strips and 3" long. So all I did was start out with a larger diameter piece of tube than the motor dia and started heating it and closing the zip ties.

crash · 08-03-2009, 03:08 PM

So it started to take some shape..

So next step was to repeat the process on a piece of 1" dia tube. Here is what I finally came up with.

I decided to drill holes and loop small zip ties thru the holes to hold it into place. Will see how well this holds up.

But here is the end result

EvilTwin v2 · 08-03-2009, 06:21 PM

That's an interesting idea with the motor sheilds. Keep an eye on the motor temps, and report back whether they stay cool or get hot. (I'm curious)

I ran pack on my course and I could still touch the motors. Heading out in a few to meet a buddy and do some more testing

Thanks for the vid. Those little motors can get up and go!
