Default Driving Style / Throttle Control

This is kind of hard to explain.

When hitting a jump almost always the nose of my buggy is coming down first. I understand that while in the air if its going down nose first to hit the throttle to pull it up and if wing is coming down first to hit the break to bring it back level.

So is it a feel type thing when you drive or is it technical before you hit the jump. Depending how I come out of a turn sometimes the throttle is pressed later than sooner when hitting the jump.

How do you know how much throttle to give and when to give it.

Well it is kind of ahrd to explain, as it was kind of confusing to read. Are you talking about when to give throttle in the air? Thats easy.....try different ways and see what you liek best. I prefer to accelrate a while before the jump then let off when coming up the face and give it a little blip at the top. This way, it stays pretty evenly and you dont go way over the backside.

You also want to make sure your brakes are not dragging. That will cause the nose to come down when you let off the throttle while you jump.

I am with jrwoodchuck on this one but I like to get the front of my car coming down pretty quick when jumping. I try to enter the jump with speed and then just give the throttle a slight blip and try and backside the jump, if everything is going my way.

Like it was said above, practice.

However, when you practice the most common way to do a jump is to

1) Accelerate to the base of the jump
2) Let off the throttle while the vehicle transitions onto the face of the jump
3) Accelerate again up the face to the appropriate speed to downside the jump
4) Let off the throttle just before the vehicle leaves the top of the jump.

The basic strategy above is done to strategically compress your springs then let them rebound while leaving the top of the jump to supply a farther jump with less power required.

As you said in the air you can wait to see how it's reacting and the give it the appropriate throttle input. I like to wait until just after I've reached the pinnacle of my jump before applying adjustment throttle input.

How do you know how much throttle to give and when to give it.
Also check your rear down travel. Keep in mind too much rear down travel can allow the rear of your car to rise too much off jumps.

Just a thought...

also a good speed throttle servo helps too. allows you to make your mid-air adjustments faster

X-Ray Freaks I swear. You know I didnt become a Losi guy because of the brand. In fact I went into my LHS to buy an associated RC8 and left with a Losi cause the owner talked me into it. I didnt even know what a Losi was until I stumbled across these forums.

I am using a hitec 7955 for throttle and steering.

Thanks for all of the info. It makes sense to accelerate to the jump, roll up the jump an hit the throttle right before the crest of the jump. I have been accelerating all the way through the jump and letting off right when it hits the air. The problem I have is my track has a set up where the jump comes after a complete U turn with little space before the tripple and then another U turn immidately after the jump.

Like said above make sure to "preload" your suspension on the face of the jump.

Oh, and are you SURE you have enough torque for your brakes with that servo! LOL

one way to hit the jump correctly without crowding your mind with procedural how-to's is to jump in a way where the engine is at low rpm in the air, preferrably near idle. if you come off the lip with the engine singing then you used too much macho with the throttle finger.

The beginning of the jump doesnt start at the base of the ramp. It starts way back from there with the setup and line you use to get to the jump.

If you find yourself forcing the car to jump due to a bad line leading up to it or because of last second correction or poor traction then you are better off rolling it and hoping for better luck next time around.
