RE: Need a kit for an .061 engine
The answers you are getting are covering a broad range.
I really like the DARE shoestring kit for the 061. I think it would be quick but still nimble.
I own this kit, but have yet to build it.
An old ace pacer or GLH kit would also work well for the 061. The possibilities are endless.
and lastly, there are countless new eletric arfs that would convert nicely to an .061 from warbirrds to aerobatic.
please let us know what you choose.
