Center section dry layup of skin. Tail section glued in with added web pieces under rear spar. Need to work out wire and airline locations and system before I glue this up.

Satellite receivers installed and bound to the Elite radio. I think on the next build I will use Xbus rather than the two radios and PWM. Problem I see is the wire size to handle the multiple servos current draw to the receiver. If you go to digital servos, you can draw 4-5 amps per servo causing a 50 amp or more flow through the receiver. I need to find out which receiver handles that amount of current. Xbus costs need to be compared as well.

Leading edge and hatches installed but hatches not screwed in. I am considering another hatch at the wing root for access to the connectors.

Dry install of front skin on center section. Will leave center section in the middle open for access to fuselage for air lines and servo leads.

Receivers, Smart fly boards, test batteries and one test servo. I use the Smart fly switch which has worked flawlessly for many years.

Center section is next to be closed. I wonder if I should leave the center under the fuselage open for connections. I don't think I need the skin there for strength.

Flew with it on Monday and it feels very strong and smooth. It is a real pleasure to fly with this radio. It is smooth as silk.

Nice radio. Took several days to learn programming and setup to use on my testbed 83" Stik. JR has some work to do to get the manual and the radio to match, hopefully soon.

Installed the receiver/servo batteries as far forward as possible. I hope to keep the amount of lead shot at a minimum. These are 4 LIFE 3200 batteries, 2 per receiver for redundancy.

Dry fit of skin, however, have more internal things to get done before I glue it up. I am looking forward to close up the wing.

This shows where I changed the plan (flexibility) to feed in the wire. Now the servos will use the new wire tubes (white) and the nav. and landing lights will use the front wire tube (brown). Now will use 2 lead connecters.

installing access hatch bass wood structures. Stiffened some ribs which were cut. I added more glue area for the shin around the access structures. Access hatches will be 3/32" plywood and screwed down to the hatch structure.

The B-25B has nav lights flush on the top and bottom of the wing as shown (arrow points to the location). Note, the location of the landing light, which is located in both wings.
