Drogon is a beast. I've flown her with EMAX RSII 2206 2700kvs and the RCX LS2207 2700kvs. Either way she rocks. I have had her over 140km/h, but I'm sure she will do more if I put on some more aggresive props and give her a bit more space to get up to speed.

i designed and printed all of thr extras with freecad and cura. The hump on the top holds a matek gps.
