Tail Servo

Started this discussion. Last reply by Rob_Lefebvre 22 hours ago. 2 Replies

Curious if the Pixhawk can only support servos at 1520μs? When I look at most tail servos they are usually running at 760μs. Will the Pixhawk support 760μs? If not what Tail servo would you suggest?…Continue

I was able to get 5 flights in today mostly in loiter and it's pretty rock solid. I am curious what it will do with a little wind. Here are my params for a Trex 550 stretched to a 700 running 1500…Continue

A little confused on setup. 1) Can I run Helicopter mode H1 on the my transmitter? I like the menu options with Helicopter mode on my transmitter rather than Airplane mode. 2) Hooking up the ESC to…Continue

TBS Discovery Down

This was probably my fault but just want someone else to look at this.Before taking off I noticed my HUD was canted to the right about 10 degrees. While airborne watching my HUD leaning farther and farther to the right. The quad thought it was leaning right which it was not. I tried to land before it got any worse but it was to late I was giving it full left input on the stick to land but it took off right. fortunately it hit a tree and fell down from there. I honestly think my old tired APM2.5…See More

"Thanks for posting. These helis, in my experience,are very resistant to wind. I have flown my helis in gusty winds up to 30mph. At those winds the pixhawk handled pretty well. They fly just as well as in calm winds. I like the braided wire covers.…"

"KDE motors are a must have for these helicopters they very reliable.  Yes I 3D printed the GPS mount. I also printed the plate that the Pixhawk sits on and the battery tray. I can send you the files if you want them?  "

"Thanks for the reply.  great flight time.  I did not know of any low Kv motors that were that small in diameter.  Thinking of stretching my 550 to a 600. If I do my stock Align 1220Kv has got to go. Regards David R. Boulanger"

"David, Yes my frames are the stock width. My motor is a little outdated but still works very well. I was running 2 7s 7800 MAH batteries and getting 30-35 minute flight times.  Motor Specs  http://kdedirect.com/KDE600XF530.html "

"I have been using the supplied APM power module that comes with the Pixhawk so that gets a constant power from an external battery then I use a BEC to the servos. "

Dear Sean Whitney,

I saw a video from your Trex 550 in Loiter Mode. The heli is staying very 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

Manuel
