Maxxslash (could use some RCM direction)

http://www.youtube.com/watch?v=mxm7M3lKU1Y The last video, from my first runs.



After that success, I Broke the shocktower at the upper mounting link. It just couldn't take the strain. I was bashing it with my buddy at the park, and his E-revo, mine didn't make it But it lasted longer then my stock 3905 did when I first slapped brushless in it, so I think I'm on the right track. But I'm happy enough with it to know I'm willing to drop the money on the shocktower it takes to make this work. I think all it would take is for the shock tower to be about 3 times wider then what this one is.

Great job!! I hope alot of people attempt this! Have you posted on TRX? I see what you mean about the lack of pulsh in the front. Still its great! I know you'll get the shock tower worked out. I guess a medusa 50mm would be fine like you said on 3s might be okay. I would really love for you to weigh it. You know you lack about one or two specifications for EVERY race class with this truck? LOL. I would love to see it with a orignal Maxx body on this! You might want to make the shock towers out of Full Force.com's carbon fiber. It would really free you up on what you could do. I just bought and built some of it for my Maxx.

Thanks. It really is a pretty straight forward mod. If someone were to make a shock tower that would just work, it might become popular. I'll be getting a weight soon. But by feel, with batteries and all RTR it feels about 1-2 lbs lighter them a E-revo with no batteries. It's funny about the race class, I've been thinking about this lately. I've got 3 vehicles based on Slashes, that IMO handle way better then stock ones do, and would be fun racing. But none of them fit into any class that I could race. Maybe a Ten-T class would let me race my ST Slash with them. I've never worked with carbon fiber, would it be easy to make a shocktower out of it?

So I got some weights today. With a 4s 3900 lipo, the one I plan on running, it was 7lbs 8oz , RTR. By comparison, my E-revo with MMM combo, and 8000mah 4s, with Mashers, was 10lbs 14oz. Throw in the 9000's, and Big Joe's it was 12lb 8oz

I also got an initial reply from Mike, and am waiting to hear back so I can get the shock tower going. I can't wait.

It's up and running again. Got a few packs through it, and so far so good. I just went with a New Era tower, and tweaked things some, and it seems to be working. I put a Xerun 80a combo in it, and it seems to be a good system. I need some lower gearing to run it on 4s, but surprisingly it does good on 2s, geared 16/54. I also threw an old Revo body on it, and some truggy tires.

That is amazing! I wish you could have gotten better pictures of the tower though. What happens to the front upper arm when you go to wot? Does it twist?

Thanks.
I didn't do anything to the tower. With the last tower I dremeled some of the bottom off, to clear the driveshaft, this time I dremeled the driveshaft. I then adjusted the spacers, so that if they move back, the nut will hit the chassis. I also used the link brackets off the old tower as a spacer, hopefully the additional surface area will add some strength there.



The front end seems to be pretty stable , it's kinda hard to know what's happening at WOT, but generally the front end is skyward. :) Lifting the truck up, and blipping on the throttle expands the tires like crazy, but has no visible effect on the front. For all intensive purposes, it seems to be just as strong as the rear.

But, real bashing has not been done. A few jumps off smaller ramps, lot's of wheelies and grass, is great, but until I get some good air, and this thing walks away unscathed, I can't call it a success.

ramp it!! ramp it!! ramp it!! ramp it!! ramp it!! ramp it!! looks great asheck...you need to launch it a few times on video. i wanna see that thing earn it's wings.

Thanks man. I actually already made a couple little vids. Not a big ramp, buy I'm trying to ease into it. BTW I pulled a backflip off the rock, right before I left, of course the batteries in the camrea were dead by then. Max temps after 30 minutes was 110 on the motor, 95 on the esc, doing 35mph on 2s. Never would have thought it would work .

LOL I think it is a success already. Those shocks really don't support that weight adaquately lol time for some super shocks I liked hearing the helle

[Kcaz25]

THe second vid at like 35 seconds you hit that rock pretty good with the front suspension, and it didn't seem to flinch!

If I was planning on more heavy bashing or track then it would be to soft but I like the shocks set up very light, to allow some good flex. I like to let the suspension move good, but it actually suspends nicely, I'm pretty happy with this setup. Though I'm sure at some point my front shocks, to match the rears, will find their way on.

Uhh, yeah, I did that on purpose to show it's durability :0

Some harder bashing vids. Still no breakage. Put the 1/8 shocks on the front, they do work a little better, but bottom out before the chassis does, so some adjustment is still needed. :D http://www.youtube.com/watch?v=NLXtwx_DDbI

The back flips are awesome! Great job asheck!! When are you gonna call it a success? Because the test are in and they are positive. Traxxas would be wise to market such a truck. I'm glad to see you use 1/8th scale shocks. What brand are they?

Thanks. I would call this a success, however I'm not ready to make it my beater. I've had about 3-4 hours of runtime , and only had 1 nut loosen, and did rip a shock screw out of the rear RPM arm. That's better then my 3905 did, by far, and comes in at under 7.5lbs. But I think the main thing is it works on a handling, and fun factor, and while I'm sure it's not the strongest thing out there, it is the only one.

It took a couple jumps to get the hang of this truck. Being that it is still running on 2s, it has very little braking force, and is not near as easy to control in the air, as my E-revo. The shocks are just like the rear, Hyper 7 fronts. They work pretty good as mounted in the stock points, but a better multi-postion tower would be nice.
Speaking of 2s, I can't believe how good 2s is doing. I'm running right at 35mph, have very good torque, and have yet to see temps go above 120 on the motor. I'm getting an easy 45 minutes of runtime , before hitting lvc, this with 2 Blue lipos 5000mah 20c paralleled.
