I turn in the direction I want to go . At our track there is a double with an immediate left so I turn in the air hold it when I land then it helps rotate my cars through the turn.

Steering in the air could help setting your car up correctly for the next section or to balance out the car while in the air. A very good example was seen at the 2009 Off-Road Gas Nats at Leisure Hours, where there was a double between 2 left hand turns. If you did not counter steer the car in the air to flatten out the car, you would land on the outside wheels. By counter steering in a section like that and using the throttle a little bit, you can bring the inside of the car down to land on 4 wheels instead of 2. It's counter intuitive, as you steer (in this specific example) right, while you are between two left hand turns.... For sure takes practice to get it down!

Just my 2 cents
I agree scub in mx is way diffrent from rc scrub. In rc scrub you want to get low to save some time, and you dont really whip the car. The fastest scrub in rc i see is carry speed then at nose tap brake and u should scrub and perfectly nose the jump allowing you to gas it smootly on the landing for more momenom. Or when ur a lil to far nose down hit gas and straighten the car. Not real hard to do also steering in air is easy. Its like a reflex to me, and you know how the car should react to what ur doing, most just twist back and forth for looks. Also turning can pitch the car a diffrent way for like i said before to line up for a turn. Also like rider said, Rider is spot on imo!

here is a good video of the suspension unloading at an angle and not rebounding up for a motocross scrub. showing its not possible with an RC car.

+ YouTube Video
ERROR: If you can see this, then YouTube is down or you don't have Flash installed.


Yes its an old vid but it shows the suspension movement best.

not always true. there is TONS of ways to scrub in MX. you dont have to lay the bike over on the take off to stay low. i could stay lower than most people that lay it over and i didnt, you can turn the bars at the last second, take feet off the pegs and brake up the face and stay much lower with less effort... but this isnt a MX lesson .... but same goes for RC if you flip the wheel at the last sec or brake up the face you can stay far lower than anyone else so its like scrubbing ... scrubbing came from scrubbing speed, its not always like the MX video of Stewart.

Whipping the car in the air is certainly not just for show. It is very useful when setting up for a corner right after a jump, or to flatten the car out after a bad takeoff or even to correct the car side to side on a landing. It takes some practice to get it right, but it can be very useful when you do.

What you describing is soaking up a jump to not launch as high and you will loose a major amount of speed doing that. When a scrub is preformed properly you are going way faster at the face of the jump then you would if you were to not scrub it. But like you stated this is not an MX lesson. If you want those and live in MN PM me and i will be glad to help you out.

THanks guys! This slowmo video is perfect. It appears he turns opposite of the direction he wants the car to rotate and hits the gas. He turns to the left and hits the gas and the car appears to simultaniously rotate back, pitch to the right, and spin to the right. It seems that pitch happens more at first and more spinning the longer he holds it. THen he turns back to the right to pitch the car back to level before landing....what do you guys think?

It's the same concept as Motocross. If you turn off of a jump, you can approach is much faster and not overshoot it like someone above said. You can also do it to set-up for a corner that is right after the jump.

If you were jumping into a right hand turn, turn the wheels to the left. this will make the car fly so that the right wheels are lower, this setting it up to turn right. right before you land turn back to the right and accellerate through the corner. As a retired mx guy there are ways to stay lower on jumps with an rc car, mostly brakeing or letting off on the jump face and letting the chassis drag.

I'm sorry but there is no way to "scrub" the way James does it on a motorcycle. Try to find an atv racer "scrubbing" a jump like james does, it has more to do with the number of wheels than anything else.
