FPV with OSD

Went out to fly with the fully integrated OSD Pro and eLogger v3 this morning. Had 3 major problems. First, the weight was too far forward in the plane and caused an immediate nose-in on first launch. This caused a second problem, which was I stripped the tilt servo on the camera, so it was locked in place. Third problem was again with the video goggles (no video out and it refused to function AGAIN). I suspect having the cable partly out of the socket doesn't help, and I need to get the right cable from Gordon (sigh...I really want to fly first person). Also looks like the TempA sensor was not properly zeroed or something. I managed to download the data from the eLogger to the computer and get GPS locations and plots.

The motor lipo was again very puffy, and never saw much over 20A on the logger, and these are 20-30C 2200mAh, so should be good for peaks up to 40A. Seems like one cell is really suffering and I'm not getting full charge out of the packs. I may have damaged these at one point in some of the other planes. One more good reason to begin flying with at least an elogger in the plane to evaluate max/average current draw. I also was unable to engage the RTH function for some reason. It should have been setup properly last night, but it didn't engage when switching off the Tx. Have to play with that more. It was impossible to really navigate the displays from the LCD on the camcorder, so couldn't really do much. Need to order some new LIPOs from Hobby City.

I also really have to figure out my camera exposure settings. Too much red. I'm really not happy with the display I'm getting. Need to get some ferrite coils to try to clean up some of the interference too. I tried to get the RtH (Return to Home) feature to work, but it appears that while I went through the safety menu and set everything up, I failed to enable RtH mode. LOL. Spent some time tonight getting the bum striped servo swapped out and resetting a lot of the features on the OSD. I need to get the right cable for the glasses.

Oh, and if you haven't seen this video of two guys flying out 4000m and back. Pretty cool. Notice the long radio wire antenna he is dragging about 49s into the video.

  1. Got another cable that seems to work with the Myvu goggles that Gordon let me borrow. Had to ohm out what was shorted to what on the cable and found one that had video on the top position (actually, it works with my cam-corder cord, just have to put video into red and audio into white). Now, if the damn rain would just stop!!!!
