I disagree - you haven't had any usable input on this forum for the past 4 or 5 days, unless your goal was to troll Mantis. A reasonable argument can be made that you haven't done it in months; and maybe ever. IMO George wins races in spite of that he believes he knows, not because of it.
And so this is completely clear and transparent to all users on this forum - I'm not attempting to get at you, or show you up, or one up you, or anything of the sort.

I win races cus I have access to good advise from Ae Team drivers ..
I do my best to share this info with everyone , not dissing anyone or their products, ect ....

Alright so this brings up something that I have been thinking about over the last few pages of this thread.
Jumping.
Generally speaking, I haven't found many setup changes that will single-handedly solve a trucks jumping problem. Alot of the issue has to do with approach.
If your truck/buggy/short course/etc is jumping nose high or nose down consistently, there's a good chance its bottoming out on the face of the jump and rebounding too soon. Every jump is different and with that each requires a different approach. Some jumps require you to roll up to the face and accelerate up the face. Some jumps require you to accelerate to the face of the jump and let off going up the face.
If you have tried multiple approaches and it still isn't working, try walking the track and walk the line that you normally run. Check for rocks, holes, etc on the run up and make sure you are hitting a smooth part of the face. If you are hitting a section that has a massive rut or bump in it before the actual takeoff, the suspension will unload and cause the vehicle to jump incorrectly. It is even more pronounced if you only hit the obstacle with one side of your truck.
If all else fails, then its time to look at your setup. If your truck is jumping nose down (on every jump every lap) then you might have too soft of a front suspension package compared to your rear suspension. If your truck is jumping nose high then you might have too stiff of a front suspension package compared to the rear suspension.
I can tell you that, there are times when I am hitting a jump perfectly with the right suspension and i will want to bring the nose up with the throttle but it just doesnt come up. And I'm not talking SC10 4x4, all vehicles.
As for the jump in the video. That thing is MASSIVE! There is no way I'd be hitting that thing with anything other than an 1/8. Granted I would definitely try it with a 4x4 but I doubt I'd even think about it in racing.
There is more to add, but this is all I can comprehend this morning!
BTW, not saying you guys are hitting jumps wrong or your ideas are wrong! Just trying to help people with their jumping technique!

Chris Jarosz: In your opinion, is the SC104x4 harder to adjust in the air than what you have scene for 1/8 buggies and other brand SCT 4x4s?
I am going to be doing a tear down to install a new servo, so i figured I would give the car the full rebuild treatment.
So here is my question, anyone have a link on how to properly mix diff fluid to get the say 15K weight?
Anything in particular I should look for wear wise during my rebuild?

off the wall
Hey Marcus , off the wall thought is that it could just be plain aero issue with the body just causing to much drag for the lightweight truck to carry its momentum consistantly
Maybe we should be looking at the flight limitations of our body vs mechanical corrections.
From what I have been reading and from what I have learned from you and all your track time I think you are solid enough in your tuning skillls to dial in this particular truck for any situations. We might have just reached it aero limitations in this particular jump and spped combination.
Just like a formula one, nascar , outlaw car all the suspension tweaks and motor can do so much then it all becomes aero with wings and vents and tunnels to properly control the airflow around the chassis
Have you tried running without a body .... what did that yeild.

However, yes it is harder to adjust the attitude compared to an 1/8 but really it should be. The bodies on these things are massive and up high in the air. That combined with the lack of a rear wing make them tougher to adjust. Nine times outta ten, it's not an issue as long as you have the correct approach though.

I've never driven another brand SC 4x4 so I can't comment on that.
