This is a report of my first scratch build UAV.Great News, i just finish the maiden flight tonight! Everything went well. Aileron controll is litte too less, as expected with just one aileron! ;)I have to move COG and enlage the single aileron before the next few testflights.BASICSStep1: (Still under work)/b>-Build a RC plane with at least 300g of cargo capacity.-The cargo compartment shall be located at the COG, size about 100x100x150mm.-Two smaller cargo bays. Located front and aft of the COG. Sizes are 60x60x120mm each <-- Updated-The plane should be flying stable, with a low wingloading and good flight characteristicsStep2:-FMA Co-Pilot stabalized flight-Arduino-Auto-Pilot controling ot the rudder for simple maneuvers-Autopilot can be switched during flight (remote controlled)Step3:-Installation of the GPS Sensor-Autopilot controls throttle and HeightStep4:-Waypoint navigationStep5:-Autopilot controlled (throw) launches-Autopilot controlled landings.Design GOALI like the KISS prinziple. So everything should be cheap, but good.My ideas:-Use a single Aileron on left wing only-Mount the FMA-Sensor on a movable platform for advanced Aircraft control (see Forum)-Use the standard aproach with a Adruino Board-Materials:-6mm Depron-CF wing spar-2.5mm Balsa for reinforcement-Lots of hotglue, some tape and a minimum amount of epoxyPart List:-Arduino 10000 Board for Autopilot-FMA Co-Pilot-Cheap 150W Outrunner-25A ESC-Graupner 8Ch Syntesizer RX-3s 1000mAh LiPo Battery-Cheapo 10g Servos for about everything (Aileron, Rudder, Elevator, Sensor-Tilt)
