Practical Experience with PID tuning
Started Jun 26, 2011 0 Replies 3 Likes
I am in the process of tuning an APM equipped Parkzone T-28. I have tried the "Easystar default parameters" and found it just lackidaisically wandering around off course, and uncaring about its…Continue

Parkzone T-28 Trojan autopilot platform
Started this discussion. Last reply by Bill B yesterday. 4 Replies 1 Like
I decided to use the Parkzone T-28 as the initial plane for my APM. I picked it beacause it is a straight forward 4 channel foam plane that fits in my trunk assembled and it has a huge removable…Continue

John Hestness commented on Stefan Gofferje's blog post This guy can fly!"I remember a thread about this from way back. I was under the impression that this ability was inherent in all quadcopters, maybe all multicopters? Anybody willing and able to go out and try it?"
John Hestness replied to John Hestness's discussion Parkzone T-28 Trojan autopilot platform"Bill B, the Park zone T28 is a great all around plane. I am on my third one. My first T28 was my second RC airplane, I slowly wore it out, while learning to fly. Number 2 is the one posted here, I built it specifically to use with the APM 1. It flew…"

Thank you"
Bill B replied to John Hestness's discussion Parkzone T-28 Trojan autopilot platform"I have almost an hour flight time on this new T28 build and it is working very well. I initially had the 3DR Radio mounted in the space between the wing and fuselage but that caused interference resulting in aileron jitter. working great…"
John Hestness replied to Ben Boughton's discussion Sabertooth 2x60 setup & configuration in the group ArduRover User Group"Ben, maybe it would help to post a picture of the vehicle and some more stats about it. I recently had a maybe similar issue that was improved by changing the "D" to zero on the heading2steer and servo2steer parameters. John"
John Hestness commented on Thomas J Coyle III's group ArduRover User Group"@MV,
Unfortunately I did not save my parameters, but I believe they are the default parameters except the heading2steer and servo2steer, the "D" I changed to zero. I have some other experience with tuning and it seems that the D…"
John Hestness commented on Thomas J Coyle III's group ArduRover User Group"I have been testing my slash based rover for a few weeks now. One issue that I had was significant oscillation in the steering control (turning quickly left and right). Today I tried setting the D (derivative) of the two steering PID…"

- I just finished assembling an APM. I want to try it in an airplane, helicopter, quadcopter, and a snow sled that I made last winter. I would like to automate my yard work and house work. Some day I want a light speed star ship, with an autopilot of course.

kludge "to improvise with a kludge or kludges" and kludgemanship "skill in designing or applying kludges".
A crock that works.
An ill-assorted collection of poorly matching parts, forming a distressing whole.
Something that works for the wrong reason.
A kludge is often used to fix an unanticipated problem in an earlier kludge; this is essentially a kind of cruft.

In between aircraft I built this rover. It is a Traxxas Slash frame with a piece of 1/8" aircraft plywood on top for an electronics platform. The plywood measures 16.5" x 6.5". It was super easy to build. In the next few days I will finish configuring the electronics, update and confirgure the software and test it out. …
Free AI class possibly has Drone applications
Posted on December 16, 2011 at 5:00pm 1 Comment 5 Likes
I am just finishing the Intro to Artificial Intelligence free on-line class from Stanford. There are probably many helpful things in this wonderful class taught by Peter Norvig and Sebastian Thrun. But I have to mention the Particle filter algorithm that can locate a vehicle in a previously mapped environment quickly and with minimal computation. …

Sorry if this is a stupid question but have you decided the missions you want your planes to perform? Its the missions that will dictate the PID loops you need.
If your question relates more to PID gain values, I'll need a dimensioned 3-view sketch of the plane to begin with.

- George, I am using Ardupilot Mega. The mission is just to fly the plane to the waypoints, assuming wind of 0-12 MPH (0-19 KPH). My question is about the gains, and I have linked to a 3 view below. The wingspan is 44 inches (112 cm) AUW is 39 ounces (1.1 kg) Thank you, John
