Ok yall, The manual says. Move the yaw stick to the left or right. The tail should move in the same direction (and about the same amount) as when you are in manual mode.
Unfortunately My tail rotor servo does not move unless it is in manual mode. When it is in manual mode the rotor slider moves right when I press right on the left stick and left when I press left on the left stick. Radio calibration shows the "YAW" command going in the same directions. Left = left right= right.
Tried a bench test (outside in the driveway) last night with the rotor at 0 pitch the tail servo did nothing to correct torque rotation and it would not manually rotate the Heli. It was as if I had a fixed tail rotor pitch.
When in the Heli configuration screen when I select manual control it works just fine. Granted I started set up on a laptop that my 2yo killed over the weekend and had to start radio setup over on the desktop.
I think I may have missed a setting somewhere. Setup is simalar to the http://diydrones.com/forum/topics/turnigy-9x-what-goes-where
with the only devience being that after manual swash set up I have a simple throttle pitch curve of
0 throttle = 0 Blade Pitch
25% throttle = +4* Blade Pitch
50% throttle = +6.5* blade pitch
75% throttle = + 9* blade pitch
100% throttle = +11* blade pitch.
Idle up 1 and 2 are set up as described above in the 9x configuration Thread.
I've heard this kind of thing before and normally it's been because the stabilize yaw P value is too low. You can set this from the mission planner's Configuration screen (green button on the top)..then select ArduCopter Config on the left side. You should see "stabilize Yaw" somewhere on the upper left-ish side of the screen...try increasing the "P" value..maybe double it.
yep that is it, increasing the P value gave me some manual control, Now it is time to work on PIDS and mechanical tuning. I can manually stop it from yawing now i just need to get it stable enough to lift off.
Which heli is this again? I just posted my latest parameters in "the big heli thread", have a look at those, it should give you a good starting point.
I think your pitch curve is going to be a problem. Are you saying that the minimum pitch is 0°. You will have trouble landing if there's a wind. You should have about -3° at the bottom. -1° at the absolute minimum.
It is a trex 450 clone with the HK FBL head. I am thinking that I am just gonig to scrap this project as the quad is doing everything I wanted the heli to do. That and I just got a suprise in the mail of a FPV raptor from Cheap Drones. So instead of smashing a 450 I think I am just going to move the electronics to the Raptor and fly.
