OK, I am thinking about a 1/4 scale B17G !
I will use the electrical system from 2 ford hybrids and substitute the
nicads for LyPos and place them in the bomb-bay. If they ignite I can eject them.
Thinking 2 washing machine motors geared to provide power , one for inboard engines, other outboard ( I'm partial to whirlpool dryers ).
If one circuit fails there will be two engines left on opposite wings.
For a failsafe in case of radio troubles a small trained monkey should
fit nicely in the cockpit.
Yes, this is a joke....although the wingspan would be aprox. 25.75
feet-Hmmm, anybody ?
