Yes, UPS should deliver it tomorrow! Sorry for the delay responding, things have been quite busy lately and I haven't had much time for sitting at the computer.
One small piece of bad news, while cleaning some things off the bench I found the charger for the radio that should have gone in the box with the rest of the 550...
The good news is the nimh pack in the TX was fully charged before it went in the box so you can at least get started and watch the voltage on the display to make sure it still has plenty of juice before flying. I'll get the charger in a box and over to the Post Office tomorrow or Saturday so you should have it in hand early in the week.
If you have any problems reassembling the landing gear setup, lett me know and we'll get it sorted. It's not really complicated and I marked the things that need to be marked for orientation during assembly so you should be OK. The gain settings are tuned for it to fly with the LG on and I didn't try it afterward with the gear off although I don't think it would do anything nasty without it attached. The C/G does change but I don't think significantly enough to cause instability flying just the bare 550, might be a bit stiff on the controls though.
Good luck, keep us updated.
