Fine by me if I am the only one that runs them. Not good for RCShox sales but good for me.



I agree if one guy can do it you better do it to or your not going to win. Last layout we had a triple and to double single was .5 sec a lap slower easily.
Hey Cam. i added 1mm shim under the rear camber link and also went 1 hole shorter on the hub and it rotates beautifully on entry.

I had the same problem when I ordered my boca bearings set. I sent them an email and they sent me the right bearings the next day. Just look at the part numbers you received and compare them to the kit on the website.

curious, do the losi's get that weight transfer and if so in your opinion what gives them that better throttle control. Trying to understand the difference.

[QUOTE=MantisWorx;10276930

The layout was awesome and at first i thought it would be advantageous for the AE. There is a set of quads and also a 35' set of triples that had a 30' straight run up to them. For the first three rounds of SC practice i was turning the quickest laps and my truck seemed to be dialed but i knew as grip came up i would need to make some changes and the track would get faster. What i didnt expect was the Losi's to start jumping the quads and the triples! This caused issues , me and every other SC10 couldnt either one with consistency so this forced me to once again go to drastic changes. Every Sc10 out there seemed to have the same characteristics in big air. The inability to bring the front end down and/or up wreaked havoc and inconsistency. I could do it but not comfortably or even twice in a row...... Sym and I were the only ones there with centerdifs so that had nothing to do with it, not all of us had 2 stage so that wasnt it. I think its a combo of design and weight, maybe some sort of gyro effect from the belt/motor? I THINK I JUST ANSWERED MY OWN QUESTION!THE TRUCK JUMPS LIKE MY RM4 DURANGO DEX21O.......

WHAT A DAY[/QUOTE]

Was it an air control issue or lack of power for the run up? I regularly hit the bmx track with my SC104x4 which has jumps bigger than I could imagine at any RC race track. My 4x4 seems to jump a bit nose heavy anyway so I've never really had a problem with the nose standing up. Also are you using some type of flowtek body to fight the parachuting effect?

But right now I think all of the change you get in flight is from the weight of the wheels.
I dont think a bench test is a fair assumption. You have more variables in the air, if you could somehow balance the truck on strings and do it there would be a difference. It definitely works on 2w buggies , 1:1 fwd vehicles and shaft driven TC's (Tq steer). what else can it be? thats the only difference between our trucks. i can t feel the difference on my 2w buggy on the bench either but it has insane rear grip on the track compared to RM3.

Plenty of run up power distance is not the issue attitude is and like i keep saying EVERY SC10 THIS WEEKEND HAD THE SAME PROBLEM NONE OF US COULD MAKE THE TRIPLES OR QUADS both jumps are full speed jumps. the previous track has some good size triples but it didnt have 30+mph take offs.
I was using the new Jconcepts hiflow body but tried all three of my bodies and it didnt matter. Once again all of us were having the same problem, some worse than others.

Thanks, I did not get enough runs to try the hub yet. I normally like the inside hole but have been running the middle lately. I did add 2mm to the rear I knew I was going in the right direction.

I agree it does! X-factory proved it and their buggies got better by changing the motor rotation. BUT we are talking about a buggy that weighs half of an SC 4w truck with the same power plant.

The losi's jump like an Ebuggy simple as that you can do whatever you want in the air with them including twisting them which is impossible with the SC10. It is not news that motor placement changes handling in one way or another, thats just physics. How much it changes I cant say but with the motor sitting lateral it will either push the front down or pull it down and it will also effect rear traction. Anything spinning 25+k RPMS has to effect something even if its just a little bit!

Cam think about the rotational mass of anything spinning that fast and the fact that while you are in the air 20g of static weight will make a difference we all know that. The truck is not 6lbs while floating in the air , if that makes sense.

The set-up is not mind again , the team develop it and Cody use it with great success at the Spektrum race.

That track is quite a bit bigger than TRCR ....

Sorry to reiterate, posted before reading the rest of the thread while catching up. Do you have video of the track? Are they relatively small jumps that kick hard, or huge mounds of dirty with a long smooth take off? That may be the difference from my experience at the BMX track. Something I've recently learned with my SC10 swd which has more of a nose-high problem is when I'm gassing it all the way to the lip to nail the breaks as soon as the back wheels leave the ground. If I wait until I think I have a problem it's too late to fix.

It may not be as fast on one section of the track but faster on a different section.
Great advise ...

got a link to a vid showing the team drivers dropping the nose off of jumps at will?

For the heck of it, this week, i will put the ryans setup on my truck and try it, and see what kind of laptimes i put down. One thing I noticed on their setup is that they added more droop by unscrewing the shock ends(maybe this will let my truck soar like an e buggy). That is about the only thing I have not tried.

symmetricon

no unscrewing with the latest set-up I posted ...

Cain

at Trcr right now we have a little double coming off the sweeper .It proves to be undoing for most ...
if you don't land by bringing the nose down on the slope of the jump ?

your in trouble ...

you won't crash or turn over ,rather just push out a little wide or worst slap on landing .That s all it takes to get a slower lap time .

okay. But are there any vids to see how the SC10 4x4's handle this?
