Remembering our physics we know that a = F/m.With that in mind, I figured one of the best ways to reduce vibration (which is proportional to a), would be to increase the mass of the APM. To that…Continue
I believe I received a defective motor from 3DR.I ordered the Quad kit, full electronics, with the 850kv motors.When I apply throttle, all of the motors start up (no props!), but one of the motors…Continue
One of the weak spots of the current 3DR frames is that the aluminum walls of the arms are very thin. The motors mount directly to the arm and in the event of a "landing anomaly" the aluminum wall is easily deformed by forces on the motor.
My solution was to construct "backing plates" for the motors. The plates fit inside the arms and slightly longer screws are used to attach the motors through the plates. The plates are simple 1/16" aluminum sheet drilled to match…Continue
I found a low cost, easy way to fabricate an electronics stack cover for your ArduCopter. You will need:
1 Ziploc Brand Container, Medium Square size
4 Rubber Bands, 1"-1.5" diameter
Modify the container by cutting 8 "posts" in the lip for fastening the rubber bands.…Continue
