- Instructional video demonstrating the setup of a helicopter using APM:Copter 3.3 using Mission Planner's Full Parameter List.
Another video showing usage of the Helicopter Setup page to follow.
Thank you Robert for an informative, clear setup video this will help a lot of people using APM Pixhawk FC in their Traditional Helicopters.
Thanks Robert, this is a great video, informative and well paced. I'm familiar with APM and Pixhawk for fixed wing and quadcopter, the next step for me is to put a Pixhawk on a helicopter. I searched around the web and found your video; I appreciate that it is a few years old but it will greatly assist my understanding of helicopter parameter setup.

Nice video!
..and after 3+ years, I now know how to pronounce your last name.
Thank you Rob, ever so much. Looking forward to the new video with the updated MP.
Great video Rob! Thank you for the updates. Only thing to note I believe is in the first part, the servo's should be set to 90 degree's then the mechanical linkages should be adjusted to get the swash level to ensure equal positive and negative pitch throughout the range of motion. Unless this is not required?

I didn't want to get into mechanical setup too much here. I might do something like that but it would require a video series as it would become quite long.
However, I actually don't normally play with linkages like that anyway. Typically when building a heli, I use calipers to adjust the linkage length to exactly the same length. And using LH/RH threaded turnbuckles if available. Also notice the Goblin 380 has single piece molded linkages that aren't adjustable. So, with servo linkages being the same length, the swash plate leveling tool *becomes* the servo trim adjustment indicator. I believe this method is more precise than any human can do by peering at servo arms unassisted.
So my process becomes like:
- Adjust linkages to equal length. I use a tool that actually picks up on the ID of the ball link for extra precision.
- Center all servos on 1500 PWM signal. Install servo horns so that they are as close to level as possible. It can never be perfect.
- Install linkages, and use swash leveling tool to center servos.
Beyond that, the Arducopter helicopter algorithm doesn't care about where the center PWM is. So infinitely-adjustable servo horns serve no benefit at all. As long as the servos aren't running out of range on 1000-2000 PWM across their full range, it's fine. Note however, this is exactly what's happening on my Goblin, is that the maximum negative collective combined with maximum cyclic is summing to drive the PWM's outside 1000-2000 range, which is why you see that bouncing effect when the swash is rolling around in the servo test.
hi Rob great video so much help thankyou also have you done video on the heli setup in mission pilot yet
The RCLogger 2 is the best pitch gauge I've ever used, it like technician quality, it shows pitch and roll at the same time.
Great Video Robert, can you help with this issue? Using mission planner, After completing swash set up a final check revealed that when tilting the heli fwd and aft and left and right the swash is not correcting pitch and roll in the correct direction, no matter what i try i cannot correct this problem! Is there a setting in Mission Planner that i have missed? If i set the collective setting at ccpm settings 12&3 to normal the collective works in reverse and pitch and roll corrections are correct so then i have to turn the blade grips over and all works as advertised and i have flown the model successfully! This model is a Blade 270 with 120 degree ccpm set to 0 +120 and -120.the same lay out as your Goblin can you please advise. I see other people have had the same problem!
Is a non governor esc can be used for arduheli? Or its mandatory to used governor esc?
Hey man thanks alote for your help but i ready need to ask something I am installing a Pixhawk on a nitro class 30 hirobo shuttle plus but I was lost on where to plug my throttle servo and where to plug my collective pitch servo.. can you help ?
Hi I am more into scale models rather than acro type . is it possible to use pixhawk cube to control a flybarless head instead of a dedicated gyro. I am thinking of flying auto missions using Arducopter heli with a four blade rotor.
Yep, absolutely. It's great for that. I have an air wolf that I will be setting up soon.
@@rlefebvre42 Great, i'm looking forward to seeing that
hi Rob, Is it possible to use an APM with my T-rex 600 with flybar setup?
+Bruno Lourenço Yes, there is a setting for flybar mode. This part of the code is less commonly used, however. Andrew Tridgell recently used that function and fixed it up.
+Robert Lefebvre thank you!
what is rotor type, rigid or teetering ?
Semi-rigid teetering.
@@rlefebvre42 Thanks sir, i asked because i can't see the teetering hinge. I think I can model it with the rotor dynamics in the literature without making any assumptions.
Is there an update for 3.5?
David Bitton no sorry. Not yet anyway.
thanks.
