Practice crash rebuild practice some more crash rebuild practice crash rebuild practice etc. I did a harrier landing one time with my Eratix. Came in fairly low 20ft. and came down runway trying to do a harrier and it was pretty stable and kept getting lower and slower and finally touched down and stopped. Was great have not been able to do it again however. I have torn the plane up a couple three four time trying. But i know that i can do it it is just getting it right and everthing i try it with has wing wobbel effect on me. But the bigger the plane the less there seems to be.
