Good plan. Keep going faster in stages, eventually you'll know enough to deal with That fast because afaik, it aint easy. If it was easy, everyone could do it.
I just wanted to glide, actually, but found out I need to build up a lot more skills and gather some odd electronics and materials, which I'm still collecting. So the new plan is to build what I can, lol. Speed is not an issue — I thought a good choice would be to get something with room to play with if I build a bulky plane to start with. Even the ESC, since I don't have a tester, made me go for a 40A so I wouldn't have to worry about it.
