I'm building a blimp. It'll be 2.5m long, approx 1m wide. flying altitude circa 1300m max, with remote control; i plan to fly it in visual range for starters; also I'm worried it'll be too heavy to actually fly; rough calcs indicate it should weigh 1000g and have 1060g of lift!
Struts are designed. Next: Nosecone + tailcone + control surfaces, then electronics and solar panel hangers and battery storage. Eventually: Software for the autopilot and a gas generator for extended duration flights.
