Paul over at RCWARBIRDS, the sister site of RCU http://www.rcwarbirds.com/ asked me to build and reveiw the first B-17 arf that I know of. Tough job, but someone has to do it!! And I thought twins were neat..This really stops the crowd at the field..of course betting on crash sites IS IN POOR TASTE!!! Actually was a big surprise how well it did fly for my first four engine project.
You can find the build and flight review there.
Good Luck,
Twinman

I still have one of the original prototypes that required one fuel tank for four engines.
Considering cheating and using .60 or .90 size in the nose and dummies on the wings. Even with wing engines at .25 would be insane over powered with much else. Need to move the cockpit back for scale look.
Still thinking.

twinman,
A little food for thought: those four "dummy" props spinning will create a lot of drag. I read an article several years ago about a Ford Tri-Motor model, I think, that had one engine in the nose and 2 dummies. The author mentioned, the power had to much larger than needed for a single of same size, due to the drag of the dummies. I can't remember how much or any of the details, except that it was significant.

Hummmm..Ok a ST 90 it is..but thanks for the warning. I would have thought, wrongly I guess, that the free spinning props would not cause any real drag.
Thanks again,
Twinman

No pressure there!!,,but I did not know about the big radial...and IT HAS A THREE BLADED PROP!! The turbing has a four blade and that is hard to find!!! Now it gets more scale!! Great!!
If I could finish this by Bomber Field B-17 flyin...wonder how many funny looks I would get??? Not that this issue ever comes up for a guy who flies two or more engine planes!! Down in the twins forum..we call this TwinSanity!!
Thanks for the good information.
