I had Tinyhawk II before and i found micros just right for me but I want something that can record in 4k and with more punch, so i decided to build a quad myself. Can someone tell if it's a good combination?
It sounds reasonablish to me, couple of comments. The runcam 4k is kinda big for a small quad, it has a 20x20 board instead of 30x30 which is nice for small things but not sure how much extra weight the second lens assembly and sensor adds on there. Suggest checking out CiottiFPV vids on YouTube regarding building your own micro him and NurkFPV are the only ones I know who focus in on doing customs this size (sure there are others, but know these two guys have done quite a bit of research and testing with things around this size so would trust their opinion more than my own). If haven't already suggest using eclac.ch or something similar to calculate the expected flight time and thrust to weight ratio etc. to make sure it will do what you're expecting at least in theory (generally if you put good data in you get good data out on ecalc.ch from what I've experienced)
