Twin pushers eh!
Motors in the engine nacelles? How would you achieve sufficient prop diameter?

Don't forget that McDonnell Douglas did put a prop fan on their 'demonstrator' MD80 .
It required the nacelle to stick out quite a bit further, indeed they had plans to actually sell planes with them so it would still be 'scale'.

You would at least need extension shafts and gearing behind the tail and multi bladed props .Would look very odd even if it could be done
Anything will fly given enough power

Hooray! It worked. Incidentally the chap on the left of picture is a certain Mr Ken Sheppard organiser of the various model flying events at Old Warden.
