Number of channels

Started May 9, 2016 0 Replies

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

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…Continue

"Possibly the most energy efficient way of doing this is V-22 type tilt-rotors, anything else reduces gravimetric energy density of the system. The DHL delivery drone is maybe the best current alternative at the moment ?  The Zelator could…"

Duffy replied to Randy's discussion Copter-3.3 beta testing
"Could you post your PARAM file.  AUTO-tune should create the right values for your copter. If after autotune it feels too aggressive you need to adjust the RC-feel value. in your case lower quite a bit the RC feel, have another flight and…"

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

"To increase 20 min more flightime over the 35 min you will need to add 28A more battery capacity, if your coptere can handle the new weight.  "

A demanding project for the platform in delivering maximum efficiency, and after some lamination schedule and power setup optimizations the Raptor E1 by RaptorUAS delivered the first ever hydrogen pellet powered drone flight.…

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…
