This is my second build... Wanted to try a build with the F4 Magnum 6 in 1 stack from Emax. Also loved this frame, so they became one. The Magnum stack is super easy, but has a few challenges. Soldering... the contacts are so close together that you need to be careful soldering. Go slow. I would like to have a little more protection on the sides too. I would make sure you add a 3d print or zip tie the battery wires. A little crash and if your battery ejects, it can rip right off the pdb.
The build comes in at 358g without battery.
This bird is super quick, very touchy with stock pids. Still working on those to find the right fit.
