Ongoing problem with Hybrid output shafts... - Page 2 - RC-Monster Forums

ThaMule · 11.25.2008, 07:55 AM

I am running Traxxas CVd's and twisted a set of Hybrid output shafts as well. I checked for binding in the rest of my drive train as well. There was none. I just chalked it up as they couldnt handle the power being put to the ground. A slipperential would indeed help the problem but that is like a steering stabilizer. It just mask the real problem. I have not ran it again since getting the new shafts. Time will tell.

I'm also running a set of Traxxas CVD's and snapped my hybrid V2 output shafts.

Does anyone the part number of the revo shafts I can chop down to get me going? Arct1k?

Also has any thought of or tried the genuine Hot Bodies Out drive Shafts and cups? Removing the traxxas cups all together? I assume the dog bone will slight straight in.

Part number HBSC8064

Would these be compatible with the Traxxas cvd's? I wonder how big the ball is on the end of the HB cvd?

the ball is 7.92mm

the pin is 3mm in diameter and 13.9mm long.

im pretty sure the hb cups will be to short for the traxxas cvd's

on mikey84's emaxx that we modded in lst2 diffs, we had to make hybrid cvds with mip revo 3.3 bones. since the maxx uses shorter bones than the revo im pretty sure you will need even longer bones on the revo.

some of the old ofna buggys used longer diff cups, i will see if i can find some

So will the Traxxas cvd fit the hole in the cup? How much is the traxxas cvd gonna come up short?

Here is an alternative set of cvd's for the Revo. They have bigger balls.

Would they work with the HotBodies cups?

I'm having the same problem as Arct1k.

I REALLY want to bullet proof the drivetrain on my E Revo using the RCM diffs I have.

Ofna diff outdrives. I have bunch of these during my experimentation.

Here are some pics:

Ofna mutilator outdrive:

Here's a picture if it helps. It appears to me the THS set might work fine. IIRC, the THS set has 8mm balls.

This shaft is toast. First the hole elongates, then it starts to crack.

As far as the lst diff swap into a maxx goes, I run modded revo stub shafts as outputs and use the 3.3/revo slider shafts. I try not to run large diameter or heavy wheels/tires on the revos or maxx, as they are not strong enough to handle it...

I have a feeling that the summit cvd sliders will be the best solution. I plan to swap my bpp chassis out for a 3905 chassis and beat on the lst diffs some more. I will most likely just run talons, I will balance them first though.

I have said this before, while the lst/hybrid diff solutions make revos and maxxs better, they are still 10th scale MTs. If you want to run big power and big tires or a heavy truck you need to step up to an 1/8 scale truck, such as the savvy or lst.

I am also thinking that my erevo will go back together and be sold as a roller... I am starting the muggy conversion and should have the stretched lst and 6x6 lst based truck done in 3-4weeks... I think one of my 3905 maxx trucks will go too...

I still like the maxx and revo platforms, but they are looking mighty weak compared to the lst. There is just too much that has to be done to make them truly bash worthy. At least the e-tranny is good, and the center driveshafts seem to hold up. But the diffs, arms, shocks, towers and hubs are not that great...

If you really want to make your own outdrives, just buy the revo stub axle shaft and cut the threaded portion off. I had used it before too.

George16 thanks man I just was thinking about this idea.

Thanks George16 - Do you have a part number for these?

below is a pic of the the traxxas cup paired with the hybrid outters

I also brought a set of UE drive cups with shafts off ebay - will let you all know how it goes with the traxxas CVDs- however George16 said it should be fine - so hopefully I wouldn't have to buy the OFNA mutilator outdrives :-)

George16 · 03.22.2009, 05:31 AM

The UE ones you just bought works best. I think I have 5 sets those for my diffs. UE does not make them anymore.

I don't have part numbers for the Ofna outdrives. They came with the diffs I bought.

I see you bought them from Scott(Billytrucks).

XSKAPE · 03.22.2009, 06:16 AM

yeap grabbed them off billytrucks :-)

The part number for the OFNA ones are 40006

Since I'm waiting for the UE cups to arrive, I decided to install the genuine Hot Bodies Out drive Shafts, just to see how off they were. Dunno if you can see it in the pics

Dang, Tower is already sold out of the Ofna Mutilator cups.

Where you from George?
