According to the instructions, the battery tray may be installed forward or rearward of where indicated, in order to achieve proper balance with a battery pack. It looks like I'll have to move the tray forward by a few inches.

Other than that, basic assembly/construction is finished. Wiring, radio, stabilization, etc. installation, fine-tuning and programming is next, and maybe a bit of decoration before a maiden flight.

Wiring complete, some white paint, some black paint, dual rates set up, stabilizer set up, and balanced.

Ready for a maiden flight.

I recommend a bit of paint on the tip tanks and rudder before flight. The visual aid has saved my Albatross from lost orientation.
