I have been Reading Chris Olsen posts and watching his videos on Arducopter with traditional Helis using a Pixhawk.
I have inherited an older Trex 450 heli with the old Align 3G FBL hardware. The FBL controller appears to be bad. So I have an old APM 2.5 without a compass or GPS on board. I just want to replace the failed Align 3G FBL system with the APM.
Now I have to mount the APM under the skids on the heli so the APM will be upside down.
I have Two questions.
1) Is the AHRS_ORIENTATION=8 Parameter supported in Arducopter 3.2.1 (the APM board will not support a higher rev of Arducopter)
2) Do I have to have an 8 channel xmtr and receiver to build this system? Chris Olsen indicated that throttle control on Arducopter MUST be on channel 8. Is this correct? I only have 7 channel radio gear. Am I out of luck?
Thanks in advance for replies and comments.
