About Me:

Got interested in multicopters with the WLToys V929/V949 mini-quad, jumped to the Turnigy 9XR radio and am now flying a homebuilt RCexplorer-style Tricopter on APM 2.5 with GPS and Telemetry link with 1.3GHz FPV video link.

Roger Nordin replied to Randy's discussion ArduCopter-3.2 beta testing
"Thanks Ravi, it was actually as at 2 by default (turn towards waypoint *except for RTL*). I changed it to 1."

"Here's the onboard recorded video of the flight. I love the smoothness of yaw movement with the spline waypoints.


That being said, in the initial part where the automated mission was executing, there are "jumps" in the motor RPM, that maybe are…"

Roger Nordin replied to Randy's discussion ArduCopter-3.2 beta testing
"I have made adjustments and recalibrations to my tricopter platform and done more testing with 3.2rc2. Hybrid is working very fine now, I really like it! One thing I've seen mentioned here somewhere, is that the tricopter does not spin down to armed…"

Roger Nordin replied to Randy's discussion ArduCopter-3.2 beta testing
"Hi, I was surprised at this first as well. But it seems the command line interface was removed in the APM 3.2 release due to flash memory constraints. Several critical functions, such as log management, motor test, compass motor calibration, etc…"

Roger Nordin replied to Randy's discussion ArduCopter-3.2 beta testing
"Here is the earlier day with a very slow Drift turn, and more Hybrid testing. Here the Hybrid mode is active longer, and you can see it whirling around at an ever increasing speed. Sure, this usually stems from a compass issue. But it still puzzles…"

Roger Nordin replied to Randy's discussion ArduCopter-3.2 beta testing
"Thanks for the quick reply! Here's a compass/mot calibration I did just now. Maybe not completely stellar, but well below the max 30% recommended value? Do you still believe this to explain the toilet bowling?
I have an external compass board on…"

"Have been testing 3.2rc2 on my Tricopter for a couple of flights. I can conclude following: Stabilize is just fine, AltHold as well! Hybrid and Drift mode is showing real promise, but
1. I have real problems with "toilet bowling" during Hybrid.…"

Roger Nordin replied to Roger Nordin's discussion Crash after rudder input during RTL operation
"Hi Andre and Oliver,
This morning I did a test flight using the Auto mode with planned waypoints. Yes, I understand trying out things a step at a time is the best way. Even though it was short, I did on my very first attempts Stabilize, then AltHold…"

Roger Nordin replied to Roger Nordin's discussion Crash after rudder input during RTL operation
"Thanks for the analysis of the logs! The APM is located in the center of the Y3, on the top plate, attached with velcro tape. I attached a picture of the build here. Btw, if I enable ACC and RCOUT logging, can I leave them enabled without any…"

Roger Nordin replied to Roger Nordin's discussion Crash after rudder input during RTL operation
"Sorry, I think I attached the wrong logs. It should have been yesterdays logs,
I used RTL on all three flights. I disarmed and disconnected the battery once in between. I found the two log sets for yesterday and attached them as "logs2.zip".
Here is…"

Roger Nordin replied to Roger Nordin's discussion Crash after rudder input during RTL operation
"Thank you for the reply. No but each one was just a minute or two, tops. When I got home, the charger charged 1019mAh in the pack, and it was a fully charged new 2200mAh Turnigy nano-pack pack to start with, so I think we can rule out low battery."

Hi everyone, here's a noob question! First, some background: I have just completed a build of a RCExplorer style TriCopter, and flashed ArduCopter firmware 3.1.3 on my APM 2.5 flight controller. I ran the Wizard and calibrated compass, gyro sensor,…
