iskess replied to Bert's discussion Skywalker 1900 , gridmission skipping patch and not following waypoints correct
"I still believe the answer is in the rudder. Just try trimming a ton of rudder in next time you fly the grid and I bet it will slide back onto the line."

"If you are using the Skywalker 1880 then 15m/s is appropriate, however Bert is using the 1900 which has an undercambered wing. I use 13 m/s as a trim speed on my 1900’s.  Antonie Kruger said:

"Ay is what I use when graphing in real time using the Tuning window in MP. 
I’m not near a computer so I can’t tell you what to look for in the logs. Both logs should have accelerometer data. You are looking for lateral (side to side) acceleration. "

"How do you know that you don’t need rudder? The plane will fly in a straight line of the ailerons are compensating for the rudder. Check the lateral acceleration in the logs to be sure.   Bert said:
Hi,

Thanks for your suggestions

"I’ve seen this before, especially with the Skywalker. I suspect that your plane is flying in a slip due to the spiraling slipstream from the big pusher prop hitting the tail and creating a yaw.  You can see the plane flying in a slip (crooked) while…"

"The HUD? I don't know what clutter you are referring to. You mean the map? How about a screen shot?"

iskess replied to William Tolbirt's discussion Home altitude issues in PIXHAWK
"No, Absolute Alt is above sea level. When you create a mission be certain to use Relative Alt, not Absolute. Relative Alt will automatically be set to Zero when you Arm the aircraft."

iskess replied to Marshall Cant's discussion Autonomous "Vertical" Missions In Mission Planner?
"Has anyone figured out a good way to map a vertical surface? Ideally we could use a lidar range finder to maintain a constant distance from the cliff wall."

iskess replied to Mira's discussion Skywalker x8 weaving during flight in AUTO mode
"My guess is that your NAVL1_PERIOD is too high. Try lowering it incrementally. I think you'll end up somewhere between 15 and 18."

"A BEC is just another name for a voltage regulator. You will need an additional one whether you use the main battery or not."

"FBWB is the same as Cruise minus heading hold. Not good for landing. Use FBWA or Stabilize

@M Awais, it's not a good idea to use Cruise mode for landing because you don't have good control. In Cruise mode throttle controls airspeed,…"
