I had one of these planes,

I used a Saito 100 came out about 7lbs, fairly light for ARF.
It is quite well constucted and flies very well.
The landing gear a on the soft side though.

I used pull-pull for the rudder, easy to set this up instead of
using the wooden pushrods.

I would not recommend a 61 2 stroke though,
you want something which can swing a minimum 14" prop or so.

If I had to do it again I would put a 120 4 stroke for unlimited power.
