Idk if this will help or not but, for me, when jumping the 410.3, it's a feel and repetition thing because each jump is different. What I find works best is to hit the jump even throttle or maybe accelerating just a little and maintain a little throttle (not full throttle) until about the apex of the jump or a little beyond and then let off. Maintaining a little throttle usually keeps it a little nose up and then I let it turn over to hit the back-side of the jump. If I goose the throttle right before a jump, about anything can happen off the face of a jump. It's something that has taken me time to develop a feel for and it is definitely a different feel from my buggies and truggy.
