Sorry for the delay, just uploaded the new tracks and want to report my findings......FANTASTIC !! Just what I was hoping for. The grass field track and gates is simple to remember the pattern and seems very life like in the controller. Abandon building thats 3 floors makes ajusting my flying for the multi heights a real work out. I'm looking forward to trying these new tricks i'm trying to learn on my real quads once the snow clears[. Spring???] Hope not that long.. Thanks again FPV FR> well done! Stu
