doing the "driveshaft mod"

[vdubbin21]

So some of you that have helped me out in my "help a noob" thread. Hear we go again. So im going to be attempting a version of the driveshaft mod. I know there are just a few screws on each end and the front and rear come apart. Is there more to it than that? i need to get the driveshaft out and im just nervous about getting the slipper gear lined back up. Or does that stuff just slip back together like it came apart and its just the motor and tranny gears that im thinking of? Any input would be great. I know i can get it apart but i want to make sure i dont screw up putting it back together. it would suck if i turned it on after to run it and stuff just strips out or something. Thanks again for any help it really is much appreciated.

It goes back together nicely. Just like you take it apart it goes together. Put the slipper in the motor mount and slide the rear end on. If it doesn't slide al the way down, you just hold one of the rear tires still and slowly turn the other until it slips into place. You can do it! I believe in you

What is the preferred mod for this? I am assuming you are talking about filling the front hole, preventing extra smash from getting in the drive shaft tube?

[vdubbin21]

Thanks El SOB. So no gear meshing or anything? just slides back in? Thats sweet. yeah Cameron that what im talking about. Im going to place a section of neoprene type stuff over the hole and make a puncture in it for the driveshaft to slide through.

[Cameron]

cool, the used slash 4x4 i bought had some tape wrapped around the drive shaft at the hole blocking it off. Not sure if thats a proper way of doing this so i just rebuilt the truck with no modification there yet. im diggin up some info on using a trex tail boom as a cover for it.

[grn_bstrd]

I would check gear mesh. just to be safe.

That is all it is! As grn said you might as well check your gear mesh just to be sure everything is ok. Generally its all good

[Cameron]

GRN - you did the carbon tail boom mod correct? What exactly did you have to do for that, is it as simple as cut to length and slide over the stock shaft? good idea to run the toyz slipper adjustment cover with that mod?

Here is a pic of what was done to mine. I would really like to improve on this with the sleeve mod. lol

I use the fuzzy side of velcrow. i wrap it around the driveshaft, and i use the adhesive kind, and i stick it on the chassis right where the shaft hole is. then i also use clear silicon to secure it in place for extra strength. this works perfect and doesnt interfere with the shaft at all, no extra weight or rotating mass. clean and simple

[grn_bstrd]

good idea to run the toyz slipper adjustment cover with that mod?

This cover is completely unnecessary if you use a full length tube to cover the shaft. Been running the CF tube for a while now and have experienced no rocks or debris inside the tube. I think it looks better than the stock clear cover as well. The CF tube is very very lite as opposed to an aluminium tube which also isn't very heavy. Its amazing how lite the CF tube is. I'm surprised it doesn't float away.

I upgraded my Velcro mod to the carbon fiber heli tail today. This should be on everyone's "First upgrades" list. I am extremely happy with it!

Can you post a pic of the rear portion? How far does the carbon shaft cover?

[syncrodoka]

Oddly I just ditched the makeshift cover that I had installed on the frame blocking rocks and installed the CF tube tonight. I was still getting sand and debris into the gears even though the cover was fitted tightly to the driveshaft. I am hitting the beach tomorrow so we will see how it does.

The CF cover covers the entire center driveshaft from drive hub to drive hub. I intentionally made the CF tube fit right to the drive hub and let it wear in until it was happy.

Yeah i would also love too see how you did this. what size tube did you use??

[dsanders337]

I did the velcro mod on mine and it works pretty good. Keeps out all the big stuff, but some dust still manages to get it. Maybe I did it it wrong?

[afol2524]

I found the CF tube mod

[rcDESTROYER]

I have mine set up to go all the way to the motor mount hole. I also leave the clear cover off.

Only downside there is extensive work to adjust the slipper if you need to. or are you running center diff?

[grn_bstrd]

That looks good I think I see some rit dye in my future

[Jeep75]

You can also use pipe cleaner. Seems to work pretty good. I just wrapped it around the drive shaft about 3 times and keep the original cover on.

[vdubbin21]

Success! I did the neoprene type fabric version of covering the drive shaft hole. Eventually id like to do the carbon tail boom version but not 100% on how to do it just yet. Everything seems good this way though. Hopefully the pic i posted below works.

[TCCustoms]

for those that did the CF tube mod...what was the bearing and o-ring for? not alot of explaining on the threads ive seen or shoot me the helpful thread that helped you! Thanks

[vdubbin21]

^i second that question

[rcDESTROYER]

I have the revo slipper and I have it locked down. Never need to adjust it

Here's what I did that seems to be holding up well:
I took plastic from a binder, cut it out to fit over the hole (on chassis and removing drive shaft)
Sized it up and cut it out, then took a hole punch and punched a hole out for the shaft.
The plastic will stretch around the shaft when you push it through, but remain snug around it
Then super glued and electrical taped the edges for added support

I only installed the tube, no bearing or o-ring.
I ran 3 2s batteries through my truck with paddles on the beach today and even with the outerwears cover off and sand piled up everywhere the truck never had any issues. Running through the sand box at a park would quickly get grinding noises out of the gear box with the velcro mod but with the CF tube I was mashing everything and never heard a noise.

[TCCustoms]

well my LHS ordered the wrong part but i got 2 tubes for $8 so not too bad of a deal and they were alum...Cut the tube to length and didnt have to do anything more than grind alittle off the motor mount plate as it swings down when setting mesh so here it is...Not real tight of a fit up front as shown in the pic but im happy with it for all that i had to do overall. It did also hit the steering but have yet to see how muc it hurt but i can turn down the EPA setting so it wont stress the servo

[Cameron]

regarding the contact on the servo bit there, how much would it muck the geometry up if you used the stampede horn from the kit? (the one that angles up a tad). That would lift the arm just enough to clean no issues i would think?

[grn_bstrd]

Grind a little bit of material off the arm of the bell crank and you'll loose no steering at all.

[new2bashing]

i recently did a similar mod to the pipe cleaner suggestion

i cut a donut shape from the type of foam they make pool noodles from

i put the driveshaft through my foam donut and jammed it underneath the clear cover right near where the shaft exits

seems to work pretty well and doesnt add much friction (or weight)

not sure how it would work in heavy water but i dont run there

[grn_bstrd]

doesnt add much friction (or weight)

The tube mod results in no extra friction. And if you go with the CF tube the weight gain is in the order of grams( its like a feather). Our lipos weigh as much as the whole helicopter that tube came off of.

[TCCustoms]

ok, the alum tubes keep bending so the 2 i got for 8 bux are toast now and got the CF one in...I had no issues and didnt have to grind anything as it slipped right though the motor mount bracket and pushed in par enough no to rub the bearing and it was actually alittle smaller in diameter than the alum tube but still held in place by the tabs in the chassis

[DSkjeie]

I used a jiffy maker tube. Cut the one end off then pulled the guts out. Then glued it in place. It does not run the length of the chaise but it cheaper then cheap.
