Decision made:  I will start with the B-25 and will start on the weekend.

Approach:
- build the fuse first to see how much room the fuse has for batteries and the radio
- build the wing per plan but move each rib outboard one position so one wing bay is added to each wing half (1.5"). Add two new ribs in the center.  That will increase the span 3" wider from 26.5" to 29.5".  I may attempt to add a wider chord to the wing-tips for stability.  As well, lots of wash-out for safety.
- make each wingtip plug in outboard of the engine nacelles.  Permanently attach the motors/wing centres/nacelles to the fuselage.
- leave decision on the motors until the bones are built, then do the weight calculations and decide on the motors.  Prop diameter will help determine the motor as well.
- diplomatically build in all the requests (Simon's turret, Andy baling out of the bomb bay doors, etc.)

Fingers crossed

Frank

Opened the box.  Need to get registered for the nuthouse!!!  This is going to be a challenge.

Ordered the motors today.  Want to try the E-flite 180's first because they are 3S-able.  This plane is not that large.

Houston.... we have a problem!!!

I started cutting and the fuse formers and then realized there are no wing ribs!!!!!!!   The balsa is missing.
The package was factory sealed yet I cannot find them anywhere.

Will have to fake it.
