a very small osd at $36 with the gps module included... it was on backorder since some time but i managed to grab one... :) anxiously waiting for my parcel to come...
my first ground test with APv1 was full of problems. till last summer i am working on my hand made airframe. finished the plane and solar wing is connected and tested. system works well, i tested it for 55mins until my radio battery drained.system: 35 mhz 6 ch radio (because im planning to use 900mhz x-bees for telemetry and 2.4ghz video downlink), solar wing with ailerons, planned to use APv1 on throttle and rudder. stabilization on ailerons and elevator with a hand made system consisting of a Nunchuck accelerometer connected to another Arduino clone and a working software adapted from the work of Andrea Salvatore. first attempt with a Diecimila which worked well but clumsy and heavy. next try was with a Funnel IO which is very small but connections too weak, especially battery connector disconnects often. last try was with an old Ardupilot BetaV3 board used as an Arduino clone which proved as the best alternative.Apv1 connected, throttle on input1 rudder on input2 ctrl on ch5. APv1 software uploaded flawlessly by Arduino IDE.when ESC connected everything looks fine. power led is on, Mux led is ok when engaged via ch5, rudder moves when toggled, GPS lock led is solid within seconds.problem issues:1- when AP is engaged via ch5 rudder moves and throttle is on for a few turns and then spinner stops. when disengaged, problem persists, spinner stops after few turns although stick at full throttle position... possible cause: not enough power for brushless motor?.. although the solar panels are connected to support battery with 1.2Amps... not a problem when AP board was not in the system...2- loss of signal simulated by shutting off the radio. Mux led and status led is blinking. AP moves rudder and tries to apply some throttle, spinner is on for a few turns and stops. the elevator moves down immediately (that is weird because it is not connected to AP)... possible cause: rf intervention to receiver which has lost signal... thank god the plane is not in the air...any suggestions and help will be appreciated... i can provide some pics and video...
