Report New OSD from RangeVideo in R/C Telemetry, FPV, RPV, and UAV Projects Posted June 7, 2008 Very tempting! The screen displays look dynamite! Still, alot of unanswered questions. There is no picture of the OSD and even the actual weight and dimensions are undecided. The specs put the autopilot and return to home on the same line, raising the question can it actually follow waypoints or is it just a failsafe feature. The specs show a vario function, would that be from gps altitude alone? Most are not accurate enough to do that. There seems to be an arificial horizon, how is that supposed to work without IR sensors or an IMU? In theory bank angle can be calculated knowing speed and turn radius but I've never seen it done for an artificial horizon. Will there be options for sensors, IMU, data logging, Google Earth mapping and waypoints? It does look promising, and the price is right. -Dave The dimensions of the board is 9x5cm - weight is still unknown. Vova says the board will have full waypoint capabilities before the end of july. The variometer is only based on GPS readings. A GPS is pretty accurate on relative vertical movement, but not absolute. As said, there is no AHI. Optional sensors has not been announced, and will most probably never be.
