Trouble with Video Signal After Electonics Hacking
Started this discussion. Last reply by Chris Khosravi Apr 25. 6 Replies 0 Likes
I've been working on building a nice ground control station including a Tx, and a video monitor, into a Pelican case. So far it's gone well, but last night I tried to get the video working. I've…Continue
All Aluminum Welded MultiRotor Frame. Use Frame As Ground?

I'm currently dreaming up a super simple, square aluminum tube, welded H-Octo airframe. Since it's made of aluminum, and welded, the electric path should be pretty good.Any electronic gurus have any…Continue

Starting a new thread for this, because I have an important warning for users.2.9.1 fixes an important bug for helis and quads, it prevents an uncommanded RTL. However, there's a risk you need to…Continue
Helicopter Avionics Power Supply

I wanted to open up a discussion about how we are powering our avionics, meaning servos and APM, on helicopters as they present a unique challenge in the APM world, and must be treated carefully.…Continue

"Excellent, thanks."
DeveloperR_Lefebvre replied to Dave Smith's discussion N00B Questions
"Yup, looks right to me.
I usually build a little board, or a 4x3 section of 3 pin header rail, and use that to distribute the power, ground and signal connections to the servos. That way you don't have to splice any servo…"
DeveloperR_Lefebvre commented on Jason Hilton's blog post StabilGo Camera Gimbal
"I think that patent won't hold. It specifically describes a see-saw roll mechanism, which is different than the roll-axis most of these new gimbals use, and which are clearly superior for our application. Also, it uses 1 gyro sensor…"
DeveloperR_Lefebvre replied to Dave Smith's discussion N00B Questions
"I'd never accuse CC of knowing what they're doing. ;)
As long as the ground level of the servos, is the same as the APM, ie they're linked through the servo power system, then it should be fine. However, there have been cases…"

"Yeah, bigger one was a 600, but it's a 700 now!
Still a work in progress. It's evolving from a hacked acrobatic heli, to a purpose built UAV heli.
The colour scheme is pretty basic. I just used plain white unpainted…"
DeveloperR_Lefebvre replied to Dave Smith's discussion N00B Questions
"Is he suggesting to run a ground from each servo, back to the APM? No, I disagree with that."
DeveloperR_Lefebvre replied to Dave Smith's discussion N00B Questions
"There is no "circuit" for the signal wire, as there really isn't any current flow. But, the ground level must be the same, which is why the ground/negative sides must all be tied together."

"Thanks for the report on the S100. I'll probably pick it up and give it a shot instead of the SX260.
One question I have left is if you can use that hacked USB cable to trigger it like you can with the SX260?"

"Randy, did you guys get the auto acceleration parameter in RC6?"
"I am using a DX 8. I havent had time to check out where that is coming out, the gyro channel, or the rest of the wiring.
I am not using the CCPM in the radio."
DeveloperR_Lefebvre replied to R_Lefebvre's discussion Arducopter 2.9 for TradHeli Discussion
"Are you using CCPM? Or 8 wires, and then where do you have them plugged?
The Spektrum system makes it difficult to set up for Arducopter, because the Gyro channel comes out of a fixed channel output, and I don't know where that is coming…"

Arducopter TradHeli Development: Full Auto Landing
Posted on April 21, 2013 at 1:39pm 13 Comments 4 Likes
I have been working on improving the TradHeli slowly but surely over the past few months. One major aspect I've been working on is the ability to use full Pitch and Roll I-term. Currently in 2.9.1 these are "Leaky" which limits their build-up to avoid tip-overs on the ground. I have created a robust Take-off detection scheme that allows us to switch over…

Dear Mr. Lefebvre,
I saw some videos from your heli in Loiter Mode and thought wow this heli is standing rigid in the air.
I'm using a TREX 700E and want to fly this heli with apm 2.5 version 2.91 autonomously.
Currently I want to adjust the PID parameter. The stabilize and the Altitude Hold Mode is working perfect, but I have some problems with the Loiter values.
So would it be possible to send me your PID values of the loiter mode? I think they have to be very similar.
Thanks.
Nice Greets from Austria
