has anyone run both the FT slipper and V2 ball diff to compare what works best?

I'm running a home made ball diff in mine, works pretty good and is very consistent, truck stay's nice and straight under power, but it just needs a bit more power to the wheels, thinking about the FT slipper, or building the V2 ball diff.

Thoughts please, run on loose outdoor track.

You are having the same issue that my V1 had. V2 with 4 pins will be perfect.The Cdif will out perform the VTS on anything other than ultra high bite conditions and even then its a coin flip!

Marcus does not agree with the weights that I run, but to each his own.

I have ran the 2 stagers since about December and have settled with 35/30 to 40/35 outdoor/indoor. Never broke anything. I have even ran up to 50wt experimenting with my setup and nothing broke.

Don't expect Marcus to warranty the part if you break a piston trying out a 50wt as he said not to. I'm just saying that the pistons did not self destruct on me, so try different weights and set the truck up for your driving style and track conditions... every ones different.

I build from the top with ZERO rebound in the build.

The V2 pistons will have no issues with breakage and 35/30 is a decent combo. The main issue with the higher oils is that you lose the performance advantage. if you are on a track that is smooth with all backside landings you probably will not notice much but on hard landings they will hydro lock and the truck will bounce. One way to help with this is to drill a 1mm aux hole in the rebound piston . This will soften up the "hard pack" and give you quicker rebound at the same time. Even Cam doesnt feel the need to run oils that high and his home track is straight up glue!!:lol: but to each his own..

What exactly are the benefits of the 2stage pistons over the stock. I run on a med. size high bite indoor clay track and am trying to get the truck to land and stay stuck (have more pack)will these help?


this is exactly what the 2stg pistons do......STICK!

Race report:
Well I just got back from the ROAR points race in Shippensburg, PA at G's Raceway.


The off-road track is composed of hard packed clay with an array of obstacles. The outside dimension of this track is 185' by 85' with an average lane width of 12’. The track has various elevations changes in addition to a cross over feature that is about as close to the old hot wheels tracks that one can get in radio control.
The conditions were not very good 100+ degrees out and the track was suffering (however the crew there did an amazing job of keeping it clean!). Two people running 1/8 e-buggies had RX8s burst into flames. One guy temped his motor at 306° and his ESC at 215°. However my BH 120A ESC stayed under 120° even with a broken fan! Motor was 144°. I was however grossly outmatching in driver skill.

Got there early and run some practice with my newly CORRECTLY installed V2 center diff, just wow! I could actually control the truck. For the record none of my tires worked there and I wasn't about to spend $60 on a set to use once so I ran the whole day on Calibers, which weren't' bad but weren't great. I also tested out my new Method RC Hellcat. This body worked wonders for jumping. At the end of the days during the mains a storm was blowing in and the wind picked up. I was the one of only trucks not parachuting off the back triple. I can safely say that with the new body and V2 diff I can out jump losis. That leads me to my next problem though, I stripped my last V2 spur so I ran the day with a V1 diff! I figured I had to be doing something wrong so I asked one of the more experienced drivers to teach me how to set gear mesh. Well it took him 15min to do on my truck as every time he would tighten down the motor screws it would loosen the mesh. So at least I wasn't the only one who couldn't figure it out! I also changed my rear shock oil from AE 25 to losi 20 (about AE 22.5). I had so much more grip and it jumped so much better!

The first qualifier started and the truck was doing good with a tiny bit of push do to the V1 diff but I was getting destroyed due to the lack of talent and practice on this track. Ended up with 6 laps in 5:54 (TQ for the day was 7, 5:03).

I put the 8mm mod on for Q2 and thing were going much better as I was now getting hang of the track. I was on pace for 6 laps again but me rear drive shaft popped off causing me to lock up! I looked at it later and it was a shorter front one. Oops!

In Q3 with a new drive-shaft and now ready for the layout I was off. I was on pace for 7 laps but a couple laps in a rock got wedged between the wheel and rear hub locking the wheel. I lost two laps and ended up with 5 laps. I started 10th out of 10 in the a-main.

The amain started and in the first turn mayhem I shot up to fourth, however I didn't expect that to last. 10 minutes later I was in 6th exactly where I hopped and expected to be. There was no one else I could have possibly beaten with any truck and my skill level so I was happy. I also beat the only other Sc10 4x4 by 8 secs. The results are attached. I am Danny, William ran a stock SC10 4x4 FT.

Overall it was a ton of fun and the truck was perfect in practice with the V2 and still very good in the races with the V1. I am confident my truck can win now and I am going to focus on just driving and tires. I'll post my setup in a bit.

What was wrong with your original v2 configuration ? The 8 mm mod should only be done in high grip situations not low.

Driving time is the best mod you can do.

Evil Genius jr. 07-08-2012 11:04 AM

I had to pins installed in front of the balls so I lost all the effects of the V2 configuration.

8mm mod is for loose not high grip!! It tends to traction roll on high grip.

correct


Way More traction with the standard hub & camber link .....:nod:

note : If using the 8mm mod ? Can lower the inside stud 2 mm, brings more traction ..

cannot make a decision between the PL Tundra or the JC Hi-Flow...

Best looking body ever IMO. Doesn't hurt that it's the best handling either. although it is very thin. It tears not cracks.

I just finished my first heat. During practice I broke the 3/2 rear pivot block. Being cheap I put the 3/3 on and I really liked it. Seemed more stable. The 8 mm mod seems good. Nice rotation on a high bite track. Still a like twichy at high speeds.

twisted 07-08-2012 02:39 PM

so i installed a fan about 3 weeks ago onto my truck to cool down my motor. worked well.

but just as some questioned about it cracking it did. did some jerry rigging with some lexan and super glue. hopefully this will hold till i can get another fan. the fan helped ALOT to bring temps down.
