Ive found that the truck and 2wd are the most sensitive to throttle control/nose attitude relation and the 4wd to be the least.
If you could post a video of your or other cars in this problem double jump I could help further.

well....I was running in stock so I could't really film while racing :P ....wait...I have filmed one stock B qualifying, only that I don1t have the dvd. Have to get it somehow.

If you adjust the springs a bit and then hold the throttle a little while in the air they fly straight, the buggy seems to fly straight better than the truck but both are doable on any sensible sized jump

Could you explane a little the spring setup? and what about weights? how should I set up the weight distribution? I have seen somewhere several setups, but don't know where they were.

OOOOOO YESSS!!!!! I have found pictures :D
I will update this message with the link and some pictures with comments

Here is a link to the album: http://s6.photobucket.com/albums/y20...lo/fxracing_2/

We habe been actually 32 in total :)
And that is the double ramp which previously was closer, one right near the other. (that's the B44 I've tried after the race)

Looks like your running in mud, well that explains a bit. Its hard to get enough speed up in tacky conditions as it looks in that pic. I dont know what advice to give you for those conditions.

One question. Who is here from the Netherlands or Belgium ?

Otherwise, I have cleaned today ma MadRat :) It was full of mud. I've washed even the tires :) Today I've run it for the first time with lipo, with this brushed system. I have to say again, I am really pleased with the stock Clash motor :) Does anyone to donate his? :D
BTW. What happens? Everybody is working? Too much quiet here :)

Everyone is watching the pretty cathedrals in Belgium on the Tour of France :) and the Soccer too when the cycling is over

BTW.... what do you say guys? How good are the stock MadRat tires? I am asking because I couldn't make a comparison(this is my first buggy and second ever RC car)

Stock tires are VERY good for bashing on a grippy ground. For the track, they're crap.

Well, I sometime use stock front tire when the track is very grippy, to have less streering but believe me, try good competition tire and your mad rat will thanks you !

I put the Jconcepts goosebumps on mine and the traction was twice as good on dirt as it was with the stock tyres, seriously saves you seconds a lap and twice as easy to drive. You gain more with good tyres than with any motor or battery or anything else you can think of. I didn't think front tyres would make much difference but once I had good back tyres the front didn't have enough turning anymore so I changed those also to green compound ribs and even though the looked identical to the stock tyres they made it heaps faster again

And in the front?
What do you say guys? Should I buy these shocks?...

I added some more about the front :), worry about tyres first then shocks: )

I do have now rear tires. Would have to find some good front tires too....

Look to buy ansmann shocks (x pro version), or the big bore ansmann if you whant.
The are very good and price too.

After if you would like to have some set-up they will comme with the ansmann shocks

HA! my order from Hexcrew heads arrived, now I have 3 full sets of awesome quality bolts and nuts. No more bendy, stripable bolts for me :). I even got 5 diff screw bolts to get rid of that stupid philips screw that's been driving me insane, they didn't have a 2.5 mm nut tho :S but I can get them from other places, until then I'll put some locktite on the stock one and hope that stops it from spinning undone all the time. But overall it's a good day today since the major flaw with the cars will be cured :)

About tires, elod, take :
front :
losi 7202 red
or
proline 4 rib M3
or
Jconcept rounder green

rear :
big shot losi red
or
gosse bump/flip out jconcept green
or
proline bow tie/hole shot M3

Find those tires on a US online shop (A main Hobby, Losi part house or Tower Hobbie) and take the shocks you need (asso, Losi, Kyosho) Take some rim too
Make an order with all those item, not very expensive and you'll get all what you need.

First run with my truck the other day......went about as lousy as the 2wd did. Snapped the t plate like nothing.......landed a little nose high off a big jump. Broke right inline with the screws. Im hoping it was one of the first batch of t plate(s) and my spares are the newer ones. It broke quite easily. Almost glad no one else was at the track as Id sure have been teased about it....the whole rear end spilled on the track like gutting a fish....lol.
So far its not handling as well as my old T4, it feels like its too short of wheelbase.
The rear and was handling the bumps real well, Im running 30wt with an extra 2 holes in the stock piston, holes are #57 or 1.09mm. Front is stock piston with 30wt as well.
Out of the box the 4wd is way better then both the 2wd and truck. Not sure why this is, they did more homework on the 4wd..? The 2wd and truck are good, just need more work to get things sorted, and with my kits they seem to have a few brittle parts.
I bought the rtr tires for the truck, they seem to work ok on our track, weird thing is the fronts make a strange skidding sound in the corners. They both fit the rims perfectly, unlike the losi's. Tires were coated with some unruly goo-gunk which needed an abrasive cleaner to remove.

end of ramblings...

zagonielod -> you can adjust the way the car jumps by adjusting the spring preload collar, tighten the front collar to make the nose go higher, tighten the back to make the back go higher. Loosening them has the opposite effect.

Have a play with it and see if that helps.

thanks! I'll try. the weather is good now, so I might go out and build a ramp or something, and start practicing
