I've outgrown a cheap sub 249g "throw-away" learner drone. I'm interested in buying or building my next aircraft. I'm an engineer and Ham Radio operator, fully capable of ordering parts, following directions, soldering. etc. I would like to be able to lift a 1-2kg payload (max) (for carrying my radio equipment) and would like some decent flight time (30min-1hr)?. I'm also currently taking a training course for my Part107 license so that I can fly commercially. I have ambitions of building a VTOL in the future, but do want to learn how to fly fixed-wing aircraft or perfect my drone flying skills. Any recommendations?
