Just another 5 hour endurance full electric VTOL

Started this discussion. Last reply by Dale Greer Oct 10. 18 Replies

We VTOLized the Raptor E1, at the same time we further optimized the power plant to achieve 50-80 Watt power consumption at cruise speed at 16.5 m/s with 3.5 Kg payload. All in all very happy with…Continue

Number of channels

I am operating the 433 MHz radios at a narrower range ~2MHz. I was wondering what was the right way to choose the number of channels based on frequency width of transmission Thanks Continue

Arduplane with second pixhawk

Would like to setup a second pixhawk that would crash the plane (full down elevator) if for whatever reason the plane has deviated more than 100 m buffer from the geofence set on the main pixhawk. This is for additional safety and would also ensure that if the 1st (master AP)  goes bonkers could still command the plane to crash. Would anyone know if this is possible to implement. ThanksSee More

Big thanks to the Team!

Just wanted to say thanks to the developers bringing this product out. I love it.

 Today I felt lucky and went to the field for my second ever flight with ardupilot wired to a custom made fixed wing platform for some testing. Since the first flight I connected the pitot and the Xbee at 2.4 GHz for telemetry.

 I was feeling that lucky that decided to try the auto take off, On my previous only flight I only tried manual, circle mode and RTL which seemed to work…
