Uncontrollable Leftward Yaw.

Hi, guys. I have a problem with my hexacopter yawing constantly to the left. I've tried trimming it out on the Transmitter but apparently I can't get enough trim from that alone.It has an Arducopter Flight controller running the latest 2.x firmware (apparently the board is retired and cannot be updated to 3.x). Set up in Hexa-X configuration.The copter will lift off and attempt to fly if I let it but the yawing to the left makes it impossible to control, I've maxed out my transmitter trim…See More

"ContraRotation on a flat Hexa or Octa is for Yaw control. Developpers choose to have contrarotatings motors on Y6 then Octo-Quad X config for thrust distribution staying even during Yaw. As 12 motors control card are not common on the market, your…"

"I mean I understand where you're coming from, having the motors turn the same way for each pair would be the simplest way to achieve results. But normally the contra-rotate for a reason, right?"

Darius replied to Darius's discussion Coax dodeca-copter on Arducopter 2.x
"if it's that simple then why doesn't everyone just have the motor-pair for each arm rotating in the same direction on any coaxial setup 6, 8, 12, 16 or what have you? What's the point at all for contra-rotation?"

keith mann replied to Darius's discussion Coax dodeca-copter on Arducopter 2.x
"Why counter rotate the pair on each arm ? My X8 does this but the flight controller knows what an X8 is. I do not believe any flight controller can operate 12 independant motors. But you dont have to, use the Y slpitter as you mentioned and run it ,…"

Coax dodeca-copter on Arducopter 2.x

Hi guys, I've been grounded for a while (due to a motor that I was too lazy to fix) but I'm back now, and I have questions.I'd like to eventually make my current hexa-copter, into a coaxial 12 rotor machine; a dodeca-copter. I was wondering if anyone else had done this, and how it's done.My current frame is a Tarot FY690s, modified with longer arms to be 800mm from the hub of one motor to the one directly across from it.Currently mounted on each of it's 6 motor mounts is one of these (…See More

Motors spin immediately upon arming.

Hi guys, I had to reset all my parameters to default due to something getting changed while trying to get retractable landing gear installed. I've forgotten exactly what got changed, but I've gotten it mostly back to normal. Except i don't know how to make my motors not spin while armed and throttle at 0%. All trims are centered, and trimming doesn't stop them. The ESCs have been calibrated as well as the radio. I've gone through all of the initial setup steps.See More

"I have a dual BEC arriving tomorrow, I got one with two separate outputs, because I need to power a transmitter for my FPV cam too. How is it all set up? Signal lead to channel 9 on the receiver, and radio 9 on the Tx to operate it?"

"I run my retracts from the receiver on Channel 9  just like you would a servo.  I also power the retracts from a separate BEC.  This arrangement is much easier to implement, and the separate power source eliminates the possibility of…"
