Well i will tell you. flying my E7 my belt broke and I brought it down then hit HOLD dam it. Rang churchy from EXTREME HELIS he said bring it round we will sort it out. An hour later i was there, churchy and Stu helped me repair the damage a couple of hours later we were test hovering it. I was amazed more the interaction of 2 or more people's forces combined become a greater effect thus creating SYNERGY. Thanks churcy and stu from EXTREME HELIS.
