Parkzone T-28 Trojan autopilot platform

Started this discussion. Last reply by Henk Jul 12, 2013. 7 Replies

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

About Me:
I started building robots and control panels in grade school. Now I upgrade and maintain industrial control systems. I started flying RC about a year ago and I mentor in the FIRST robotics program.
Please tell us a bit about your UAV interest
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. …

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
