Can anyone tell me what I'm doing wrong here?

It's hard to get the car to stay flat on the first jump and it keeps nose diving, but I can get it to stay flat on the other three jumps ok. I'm trying to quickly blip the throttle to keep the car flat just as I hit the ramp.

The first ramp/bump seems to have a much sharper angle than the other three jumps and it's much shorter too. So I'm not sure if it's my bad timing with the throttle or whether it's just a hard jump to tackle smoothly. ...listening to the sound of the car in the video, I'm wondering if my timing is just too early. Or should I just reduce my speed?

The car is a (probably 5-year-old) Associated B5M with 400cst oil in standard set-up: white springs at the front, green at the rear, 24mm ride height.

EDIT: Hmm...guessing I should have posted this under 1/10th off-road. If there's an admin around, feel free to move it.
