Nose up means your spoiler is to high or the angel is to steep
Cut it out lower and set it more flat.
If it rotates in the air. The left right weight balance is off or the spring/tention left /right in not set the same
Also look at your rebound L/R that can also make your car rotate in the air by already pusing the car at launch off
Also the tm2 is a light car. So wind conditions can be a factor to(only outdoor)
Side wind makes it rotate. So you need to counter steer
Hope this helps
Most times the tm2 is a great jumping car.
