Thanks again for all the help, guys! It's about a day from being in flying shape. I still have to solder the Y-pushrod for the flaps (which is currently held in place by a wheel collar as suggested earlier), but I got the camera mount placed today. It's considerably tighter than I had thought under the canopy, but fortunately the plastic adds very little distortion. I did a little taxi/runup with the camera in place today. The video's in HD, but that's going to take several hours to upload with my connection, so I've a much lower-res version as well. I'll update the video link when the HD one's up.
EDIT: HD video is up.
