I'm NOT this guy:


The powertrain spec is similar to what most of the VC-450 setups on the RC Groups thread have, but I suspect that (on 3S lipos) those motors/ESCs will be slightly under-propped (wasted weight). My main concern is that the controllers won't be fast enough, expect I may need to replace them with something better. The props feel a little flimsy and I will certainly be balancing them well before I use them.

I still need to acquire a DSM2 transmitter. Either a Spectrum/JR module for a Turnigy 9X (open source firmware, it's just an AVR with the right inputs), or borrow my friends spare Spectrum 5i. I'll find out if the 5i has a 3 position switch, I'll check it out before buying the Spectrum module.


My plan is to build a robust and strait-forward quad, then learn to fly it. After that, I'd like to switch to 36 MHz PPM control (like my planes) or fly by joystick to free up 2.4 GHz for analog video.
I mostly fly fixed-wing planes and am slowly moving to STM32, but mostly still LPC.

Project notes: Raspberry Pi ground control station

I want a cheap headless GCS that speaks to me (possibly via CB radio), keeps logs, and provides a convenient place for me to tinker with agents and such (development time) with a maximally simple setup at the field. I will probably want a build system (for reflashing firmware at the field) and integration with FPV video, but those jobs are for later.

I started with a Raspberry pi (rpi) running debian squeeze, which is what I run on my field laptop, but that was a dead end. Ocaml on squeeze is 3.11.2 (with no backport available), and that version doesn't support ocamlopt on ARM architectures. So far I've learned that I should be on a wheeze-based distribution (ocaml > 3.11, supporting ocamlopt on ARM), and I probably want to utilise the hardware float so that means I'll move to raspbian next.

My plan is to mudde through and get it working, then publish an install script that makes the install process repeatable. After that I might look into packaging, but I don't know much about that (yet).
