Well, I can give a few points of advice. The first problem I can see is practicing with a magic for beginning 3d. Those planes are absolutely horrible to learn on for 3d. 40 size airplanes are just not good to learn on. If you have to learn on one the only one to me that I have ever seen do decent 3d is a pizzaz.

If you want to make your magic better though move the cg as far back as possible but to where you can still land it. That will help alot. Also for harriers if you put in reflex in your ailerons it will help some to. But like I said it is still going to be a hard airplane to learn to do 3d on.

As far as realflight, if you have adons 3 and 4. They have the perfect airplanes on them. They have an extra and a sukhoi and an edge all already set up perfectly for 3d. If you use those setups, They are great for learning 3d. But if you just want to get pathetically easy you can go to the G2 homepage and download the aeroworks profile extra setup for the 3d and that is absolutley pathetic it is so easy. But it helps with confidence and with timing when it comes to learning. If neither of those work out let me know and I will give you a couple of other options
