I'm not letting off the throttle in the air.

As I said, I've tried accelerating.

That leaves suspension, as I first guessed, and as you said, ADZY.

Now that we have that narrowed down , could someone experienced with this car give some info about suspension setup? What springs are you using? What oil? Which holes are they plugged into?

Thanks!

Hi, try releasing the throttle before you leave the jump, this allows you to change the pitch of the car while in the air. As said before you can blip the throttle to raise the nose or hit brake for a split sec to lower it. BTw im using novak 5800 brushless motor and when you run full throttel on any jump, you will raise the nose so high.

Ride height is very important here, I'm using stock springs (green frnt, pink rears). Try dog bone level on all four wheels. Anything higher makes the car very hard to control.

I know a cure for the opposite problem. If you always go nose high comming off the jump it can be an indicator that the motor is over geared. Makes a certain amount of sense, the motor is bogged down comming into the jump and once the car leaves the ground the motor can spool up in the air. Just like accelerating up the face of the jump.

One question for ya HVAC: Does your car have the wing attached? I own both the XX-4 and the XXX-4 and the XXX-4 seems to be more dependant on having that wing.

My car does not coast well. If I release the throttle right before the lip, it will be just like putting the brakes on. Ask me how I know!

I have the wing on it, although it's a flimsy piece of trash. I plan on buying a new body/wing set soon and beefing both up. I'm thinking what would really be neat is make some fiberglass/carbon fibre molds, actually. And unbelievably durable too.

Today I purchased Orange and Red springs for rear, and Green and Silver for front, so I have lots of choices now. It seems the only cheap part for this car is extra springs.

Guess I'll see how it turns out tomorrow, if it's not raining still

I liken it to living in London, or Seattle, lol.


Everything I read says to have the CVDs level. I put softer springs (silver front and pink rear) than what other people are putting, and my car still sits far above level in the front, and a little above it in the rear. Everything is in it, servo, esc, reciever, motor, batteries. Why does my car look like one of those cars the Mexican guys drive around in all day?

Anyone know how to stop the batteries from getting scratched up on the bottom? All I can think of is screwing a piece of lexan to the bottom of the car, but I wanted to check and see if anyone has a better idea.

Thanks!

I had the same ride height problem, it seems that some xxx-4s came with these blue shock cup things that are considerable larger than normal ones, i run green 35 red in front and pink 32.5 black .160 in the rear, i have no ride height problems but i do have nose diving problems, even tapping the brakes on a wheeler brings the front so far down ive had it go upside down and still land the jump with a little throttle control, the hotter the motor the farther down it will go. to solve it if you have enough room just tap the brake and even it out with throttle.

Instead of screwing it on, associated make a sticky backed plastic chassis protector sheet for the job

Because the Associated stuff is 8 dollars and the sticky stuff will probably go bad and it will fall apart (just like everything else Associated makes (jk lol), and in my world lexan and screws are free

Default BK Bones

I was wondering if anyone could list the advantages/disadvantages of BK bones on the XXX4, and when to use them in the front (Pudge worlds setup) and rear of the car?

My XXX4 is grossly over weight, 160 grams over. It needs a diet, so want to know what the graphite parts weigh to see if they are worth buying. Already have the graphite front arms and have the G+ front and rear shock towers and rear arms coming.

Weighs in at 1749grams and weight limit is 1588.
