Funky stuff here and I can't figure out whats going on. All sunday we were hitting the ramps pretty hard and occasionally my car would nose up real bad so i'd hit the brakes to bring the nose down. At full brake the nose simply doesn't go down...

I checked the front and rear brakes and both binders are working just fine, I can hall it down from 50mph or so in about 10 ft. I checked it while holding the car up in the air and all 4 wheels stop when I hit the brakes. The cams move freely, and the brake bias is close set so that when I hit the brakes its nearly equal brake bias front and back.

Any other reasons why I'm having trouble getting the nose down? I've had problems before on my other buggy when the front brakes weren't working, or the rear brakes not working. But both front and rear brakes work fine.

Funky stuff. Anyone have some ideas as to what else to look at? The wing is set to normal downforce, so its not putting massive downforce on it.

Naa that's about how my buggy is too, the tires aren't that heavy so there's not much impact slowing them down is going to have on the overall pitch of the buggy...Like MT's, they have alot of meat on the tires, and that's why with most MT's, b-flips are easy. Buggies, you try to do a backflip and it's a very very close call and most of the time you won't make it around in time. If you threw some 17mm trug tires on your buggy I bet you that you could get that thing to nose-down in an instant.

The solution; get off the gas either right when you touch the ramp or about 1/2 way up.

set the front brakes tighter than the rears and it will go nose down better,

I race with like no front brake so its a pain in the ass trying to adjust the car in the air lol

I didn't quite explain myself. A few weeks ago if I hit the brakes it would practically nose dive into the ground. Now hitting the brakes as little to no affect on the attitude of the car.


I'll have to try that, currently I have it set so that the rears are a little stronger, I like oversteer way more than understeer during braking.

This is what I was going to type as a resolution

"The solution; get off the gas either right when you touch the ramp or about 1/2 way up."

I usually get off the gas as soon as I clear the ramp, we are going for maximum height and distance here.

I used to have complete control of the car, I could bring it back level from a fully inverted position before landing. Now though its sluggish to bring the nose down even from a 45* angle.

The only other thing I can think of is that i recently changed out to a much thicker fluid in the center diff because running on pavement and general bashing was killing the front tires. I switched to 30k center and that really helped tire wear. But I ran 30k center in my old Ultra Comp 2 buggy and it had no problems nose diving if I laid into the brakes while in the air. And if I hit the gas it brought the nose up very quickly as well.

try turning ur idle down or atleast check it, if u have a bad tune or it is off, ur car may idle high right after coming off of full throttle

But i'm fully on the brakes and it won't nose down, the wheels aren't even moving anymore. As it the wheels are locked and not moving in the air, which used to be enough to get a nose dive out of the car if I wanted it.

The idle is fine, comes right down.

If your wheels are locking up in air, and the nose still isn't going down, there's nothing you can do but get off the gas earlier on the ramp.

ya once the wheels lock up its over, try tapping the brakes instead of holding them on, if u hold them on it will just start to fall like a brick lol

But thats not quite hitting the real reason I made this post. I'm fully aware of what needs to be done to control the car in the air and I've never had problems with it.

However, what could change to cause such a drastic difference in the way it handles in the air BESIDES the driveline. I haven't relocated any components rearward, I haven't increased rear downforce or switched to a different body.

The car used to nose dive on command, and now it wont. See what I'm trying to get at? I'm looking for solutions other than lay off the gas earlier. I used to be able to right the car from an inverted position as in lid down, wheels up completely to landing on my wheels just by locking the brakes.

I'm looking for other causes besides the wheels centrifugal force. its not reacting the same in the air as it used to and thats what I'm trying to figure out.

you didnt switch battery packs?

Nothing has changed. The only minor change has been that I dropped 30k in the center diff instead of the 10k that was in there. However, when the wheels are locked under full brake then the center diff isn't even moving so that would n't affect the flight attitude unless it was spinning.

The last major change was dropping the OS 30vg in there, but that was weeks ago and it just changed from last week to this week.

did you have the ramp in a slightly different location, maybe a different angle?
