It's hard to be sure, but a Norvel 0.061 is probably pretty close
(probably erring on the side of more power). With the lower weight
(no big battery), it will probably perform even better than the
electric motor. You could probably do a 0.09 easily enough, and that
would have *plenty*
of extra power.
I can't tell what the plane is covered with -- make sure it's fuel
proof, and don't forget to fuel proof any exposed balsa. And beef up
the firewall -- the stock firewall probably isn't going to handle a
glow engine well.
It might require some weight to balance after the conversion -- you
won't be able to really move the battery around like you could before.
Well you can, but it's a lot smaller, so the effect is less.
Personally, I'd leave it electric. If you need more power, get more
cells, a li-poly battery and/or a better motor ... but a glow engine
could work too.
