Model Components
RD4 was built by Myself and My bro Duane (Bam Bam). He did a great deal of work on his "baby" This Octo has yet to fly but flight tests are coming soon. This UAV will be flying over and monitoring and filming the potential flood threats in the Hay River Delta during floodwatch this spring.
UPDATE: After working for considerable time on the UAVX platform, I have removed the UAVX flightcontroller and moved to an APM/OilpanH
UPDATE: A redseign to Coaxial Octo with Aeroquad put RD4 in the Air.
Currently an X quad
RD-04 test flight and crash
Well looks like the day I crash everything. I took Bams octo with APM running AQ 2.4 out to make sure it still flew ok ..... nope. Still has this crazy jerking thing it does, and this time it jerked into a tree , cut its own power (I was monitoring it with the telemetry on Bams Rado, a dx-8) and broke an arm off. Arg! Looks like I will be rebuilding this thing again into a smaller octo or quad, some thing that can at least stay in the air. This is no longer able to fly. Into the shop it goes.
RD-4 Undergoing dramatic rebuild
So today, I disassembled RD-4. After the big crash I decided to rebuild it as a quad with 12 inch props. I shortened each arm from 347mm to 180mm. this will significantly reduce arm breakage risk and still allow for a wide range of prop sizes. [PHOTOS TO BE ADDED HERE]
Bams Octo (RD-4) Becomes a Quad
The Model is coming along nicely and now we just need a flight controller and we are in business.
RD4 - new triblade props
Today RD-4 got a set of tri blade 9x7 props, smoothed the flying right out.
RD-4 Tuning Modification
- Set the arm length to 14 CM block to block
- Reset the rotational angle of the motor about the arm to 0 (level)
- Adjusted pid tuning for stabailze from 4.2 to 3.2 P on roll and Pitch.
- Testing flight required.
RD-4 Now has maxbotix sonar
I installed the maxbotics MB1260 (EZL0) and it seems to be working in the lab.
Model Flight Logs
Newest at the top, oldest at the bottom.
THis flight resulted in a succesful test of sonar, but ended in a crash that broke an arm, this frame breaks an arm every crash.
Testing sonar, it was working in the lab, but not in the flight, I think its the mode switch.
Flew till battery alarm was on full alert then took off again and it crashed when it ran out of battery.
Testing new pids in variable 15km winds. We have a winner, no wobble at all.
Just testing the effect on stability from 9x7 3 blade props.
Still wobbly but pretty good, need tuning. Kind if windy.
A timelapse video of my AeroQuad v2 shield build using a gopro. The music is by Apocalyptica. This flight controller was originally built for RD-4 but is now used in testing airframes.
Just a quick timelapse while I build the DIY Drones Ardupilot Mega 2650. This flight controller was built for RD-4
RD4 - Redesign AQ 2.4 Coax X 8 - Test flight with Alt-hold
In this video it has been rebuilt from a radial UAVX Octo to a Coaxial Octocopter, running Aeroquad 2.4 Flight Software on Arduino Mega with AQ shield V2

First air time with UAVX octocopter RD-4.
