B-25 Mitchell DTFB Build

[Blackbeltrrf]

I just started a B-25 DTFB Scratch build that I would share the progress as I am proceeding through the build. This is a design by Phoenix1962 who has an article on the FT site on this build as well.

Wing span will be 59.9"
Length will br 46"

Wow! That is pretty intricate construction for DTFB. Nice work. What methods of construction are you planning on using?

I'm hoping to start on a 101," span, fan fold B-25 soon. My thought is to make a "box spar" fuselage with formers attached to get the proper contours. The formers will be wrapped with FFF for the skin. Should be very strong when finished.

I am using typical standard FT build procedures. This B-25 is patterned after the FT Cruiser as far as the same electronics and similar size.
Here is a picture of the belly pattern that I am yet to cut from DTFB. The skin here will be durable and look really nice for the scale like look.
Thank you for the input. More to come as I progress on this.

Here is a video of how I did my Bombay doors using two servos. Door speed can be adjusted to any speed I want them to be.
