.049 Multi Engine Plane
 

With all the .049 engines I have, I am considering a multi with .049s. Besides not being able to control the throttle, it should work, right?

Yes, it should work fine. Keep it light, place the engines close together as possible with out-thrust in both and use a large-ish vertical stab. This will help with assymetrical thrust when 1 engine runs out of fuel before the other.

If you're using Cox integral tank engines, you could drill a hole in the tanks, run a fuel line out to external tanks with fixed pick-ups. When you've flown long enough, roll inverted, push down elevator gently and both engines will starve and die at almost the same time....roll back upright and glide back in for a landing.
