Great work. How did you do the interior, pilots etc?

The pilots were from Parkflyer Plastics, which appears to now be out of business - you can check for 3D printed warbird pilots on the interwebs.
As to the cockpit, you can find lots of images on the interwebs of every warbird there is. I use those pictures to create with cardstock (thick paper), balsa scraps, and wire or cold solder the cockpit floors and walls, seats and panels, yokes and pedals I need to
detail the model.

The propellers are impressive. How did you build them or are they aftermarket?

the Mitchell out of the box and built to spec. would not be heavy for RB power. I imagine you would leave the rear section of each nacelle open and string the rubber motors to hooks installed in the horizontal stabilizer (similar to the way Dumas has set up their Widgeon)...?
The real challenge is incorporating all of the plastic details - I would instead omit most of them and probably use the solid nose (mounted with magnets) omit the top turret, maybe the waist gun ports, and so on.
You would need to lighten a lot of the balsa parts and since this one is mainly a display model it uses and you are supplied with 3/32" stringers for the construction. You might want to use 1/16" instead ?

I've done 2, 3, and 4 motor rubber powered models. The Guillow's B-25 is a little small for a full scale models with rubber power since the prop diameter is limited. It would work better if it were 30 to 36 inch span or larger. I have made multi motor models as small as 16 inch span but they were NoCals and the flat fuselage left room for the props. The trick is to keep them light with sufficient strength, design a winding stooge that works, and trim carefully. What is surprising about multi motor models is that even without opposite rotating propellers the parallel thrust lines cancel each other out and the trick is getting them to turn. The other thing is that with multiple motors a very little thrust line adjustment goes a long way.

This display B-25 is looking very good!

@ Lawlor - the props were made according to the plan using the provided prop hubs and balsa. It's the shaping and sanding of the blades that makes a difference.
There are a few videos about the process on my YT channel 'Heywood Planes'
Here is the first of a series on prop fabrication for the Flyline YPT-9 Cloudboy

Great info, thanks.

Great job! I don't have that kind of patience!

the whole purpose of my channel and my postings here and elsewhere is to give something back to the aviation modeling community if I can and to inspire folks to work on or complete projects of their own in some way.
Yes the work can be tedious and time consuming but that's the case anytime you're doing actual physical work with your hands. The beauty of this sport is that you can take it to any level you're comfortable with.
IF the information or videos I am providing give someone insight, or ideas on how to approach or solve a problem - or if someone is inspired to take up a project, or complete a project of their own, that for me is the entire ballgame.
I hope to continue doing this for as long as I can, hell or high water.
