"I have worked through the documentation of for the SI1000 and the firmware and I think from the tables that they hardcode to always run wideband FM modulation with H>2

Stephan Hiltenkamp replied to Hadrien's discussion Can't connect apm2.5 / got stuck during read params"Looks fine to me - that is what happens when you reset from the CLI. Can you flash firmware from APM and does the verify-run report success?

Stephan Hiltenkamp replied to Craig Elder's discussion APM Copter 2.9.1.b has been released"Hi Craig, thanks for your reply.
I figured the multipathing was responsible for the GPS variations. What I didn't expect was that the GPS relative motion would show in the HUD.
If I understand things correctly, Arducopter is now doing…"
Stephan Hiltenkamp replied to Craig Elder's discussion APM Copter 2.9.1.b has been released"Hello all,
I just ran into some strange effects.
Setup: APM2.0, Arducopter 2.9.1b self compile (due to my flashing issue with APM).
Story so far: After the initial update to 2.9.1, Hexa flies quite nicely in Stabilize and Alt-Hold - better than ever…"
Stephan Hiltenkamp commented on Stephen Gienow's blog post Watch Out! Udrones ARFs need threadlock."A - yes, threadlock belongs on all threads where metal touches metal.

Hi all,after an externally induced break I am getting back to putting my APM in the air aboard my Hexacopter.As an OS X user, I have had my share of trouble with Mission planner in a VM and precompiled ArduCopters, so I needed to go native to OS X anyways.Questions:1. I cannot get the Arduino 1.0.3 from the Wiki to compile Arudcopter 2.9.1 (or any other one) on OS X 10.7.5. Arduino IDE 1.0.4 from arduino.cc does work though and the board flies OK. Judging from the comments in teh Wiki I am not…See More

I did erase the EEPROM manually…"

- About Me:
- Electrical Engineer (mostly automation theses days)
- Tell us a bit about your UAV interest
- I want an aerial Photo platform and since I rapidly understood that learning and mastering single rotor CP helis will take a while I decided to go parallel with a multicopter and while flying the heli with paddles and as unstabilized as possible, pour all the electronics into the multicopter.
Just building my debut: a 3DR hexa
