Does the GPS (and compass) need to be entirely out from under the main blades?

Hello.  I am beginning the process of taking a Century Swift 16 (a bit vintage but light and strong - about 550 rotor diameter) and converting it, with a Pixhawk, to an autonomous machine.  I feel…Continue

Trex 700L Dominator DFC powered by PixHawk. 

Having issues arming by the Tx but no trouble arming with my laptop. any group thoughts. I have checked and double checked tx. direction and re calibrated  RC. Channel 8 on and channel 8 off. no luck.

Hi, I am experimenting with the AC code and need some help pointing me to a correct library responsible for mixing pitch/roll/collective pitch into the 3 servo outputs for the swash plate? also, please excuse me if this is common knowledge is there a wiki of the ac code itself, i.e. libraries, control logic?

This is my Heli actualy flying (not autonomous)

I have been watching this project for the past few years. I am waiting for a stable release for my UAV platform.

Here is a pic from the manufacture, not sure where mine are.

  • Height (m): 0.711
  • Main rotor diameter (m): 2.146
  • Tail rotor diameter (m): 0.403
  • Empty weight (kg): 16.5
  • Payload (kg): 13
  • Max take-off weight (kg): 35
  • Max speed (km/h): 90
  • Cruise speed (km/h): 65
  • Rate of climb (m/s): 4
  • Ceiling (km): 2.5
  • Power plant: 80 cc air cooled twin cylinder gasoline engine
  • Fuel (L): 10
  • Fuel consumption (L/h): 4
  • Endurance (min): 120
  • Operating temperature (°C): -20 to 50

@R_Lefebvre: Thanks Rob, as you said 10kg is much more reasonable, do you have some suggestion which heli frame I can use for this 10kg payload. we can use it to make trial first. how much could it cost ?

Comment by Rob_Lefebvre on January 21, 2014 at 2:51pm

Nate, we need to talk. ;)

that Rotor Buzz... looks like a modified Yamaha RMax?

Comment by flyingdragon on January 21, 2014 at 2:46pm

I would love to see an RC helicopter flying 2.5 hours that  big and can carry 30 KG plus it's load will be real hack!

but again the bigger the helicopter is the bigger the blades and the components,

I had Bergen helicopter few years a go I build it for 10 days, here is it, but alas my friend crashed before I even tried to do the first hover:)

We did our work on APM 2.0 - 2.5. Haven't gotten my hands on a 2.6 yet, but they're all nearly the same.

The Rotor Buzz comes with a really low quality autopilot. If you put an APM on it as far as I know that'll be the first.

Comment by kevin zhou on January 21, 2014 at 2:33pm

Thanks all the experience from your guys. 

@Nate Miller:  So you have make all the function you mention below ? quite commercialized stuffs. Do you make these optimazations base on APM 2.6 or base on pixhawk? I am interesting in pixhawk for it realtime system and hardware recovery design, but I have no idea these already implemented or just a plan and hardware ready for it.  Roto Buzz looks really cool, but the price is really hot. I just wondering if they implemented it by APM 2.6 hardware ?

Nate,  I think the latest code has come along way.  I am running 3.0.1 and have had no problems with it.  Flying 1 meter off the ground in loiter without enabling the sonar is no problem.  If I did it for 10 minutes then yes the barometer would most likely give a false altitude.  I think version 2.9 was the initial breakthrough in TRAD HELI.  Try the new versions I think you will be impressed.  My APM sits below the heli frame and my only real issue is my vibes on the Y-axis are about +-.2.  I think it's just a little to far below the center of gravity. I have never seen ground effect turbulence disrupt a extremely slow landing in any of the automodes.
