This build is another apex with all the same spec as my other 2 apex builds. Only an most important difference is this one has the kiss ultra fcfc in it. an a falkor fpv cam. my other apex's have predator v4 cam. Other then thst every single part , bolt, tpu prints etc are the same. that way I really got to feel how the ultra felt coming from betaflight on all 12 of my quads. I hsve to say when I 1st flew it i hought it really don't feel much different to betaflight tune I have. but the feel is what I noticed the biggest difference. But when this quad was on the bench for a few days with osd problems. I went back to my daily apex betaflight tuned an boy I hated it lol. For real that's when I realized how different the ultra really is an didn't want to fly till I got my ultra apex back in the air. Now I hsve to get 2 more ultra to put in my other apex's.
