"I hit the Stop Following button on my last reply a couple of minutes ago thinking it would toggle but it doesn't and I can't figure out how to undo that action. So this post hopefully will allow me to follow this thread that I…"
"I am working on an autopilot for a 40 foot sailboat. Last summer it steered my boat 40 miles. It does not have cross track error handling and I am trying to add it. I was looking at ARDUPilot cross track error handling and…"
"Alex thanks for your input ! Follow along this is going to be like nothing you ever seen before. The 1/8 aluminum on the fuselage is going to be a inverted U to attach the wings to going half way down the fuselage an exoskeleton…"
"Yes the absence of RF communications and navigation makes things more difficult under the water. This vehicle appears to have at least two acoustic transducers on the top. One is likely an acoustic communications modem, the other may be…"
"@JoeRe: interleaving, the CH-47 has interleaved rotors, so it's at least feasible. Perhaps the turbulence and vibration would make it an undesireable solution. I'll admit I haven't done my homework on that…"
"I'm very interested to see this fly! I've thought of building a variable pitch quad as a means to improving the actuation bandwidth of the rotor thrust, as you mentioned. I had assumed I'd drive the props via driveshafts…"
"I got around to doing some testing today.
I'm still having trouble tuning my nav_roll, it seems to twitch every few seconds for unknown reasons. It's not oscillating, just twitching. I didn't bring my netbook home with me so I…"
"At this point I have implemented and will soon be testing a PID for track following in the 2.26 code. However, I don't yet have any code that resets the integrator, though I don't think it should be a huge deal for an aggressively tuned…"
"I'm glad to hear about the ability to include GPS data in the DCM calculation, but I hadn't seen any reference to that capability in the posted documentation. That makes me wonder what other undocumented features the chip has.
Alex thanks for your input ! Follow along this is going to be like nothing you ever seen before. The 1/8 aluminum on the fuselage is going to be a inverted U to attach the wings to going half way down the fuselage an exoskeleton of sorts the bottom half is going to be foam and fiberglass the inverted U will have lightening holes in it of course about 1 1/2 lbs and go from forward of the wing 2/3 of the way to the front of the plane from the wing back the inverted u will taper up from the bottom and in on the sides and the horizontal stabilizer and vertical fin will be attached to it there will be a angle of incidence wedge between the wing and the fuselage depending on what gets put in the plane camera etc the wing can be moved forward or back if the COG changes the reason the bottom half of the plane is foam and fiber glass is because the antennas are going to be located inside there I am going to finish building the wing then I will draw it up Thanks again Carl
