Two consecutive days with two fatal wrecks with the Iris. Tuesday running mission with landing due to loss of radio into a tree in Harris Riverfront Park, with a subsequent 10 meter fall onto a concrete walkway. Broken arm, motor damage.
New arm and motor, calibrated ESCs, radio, but unable to calibrate accelerometers with DroidPlanner 2. Drift to starboard in any auto mode. Caught long leg on ground, twisted arm to breaking.
