now, they list the 2stroke range as ".35 to .50", but I think a sixty twostroke would be appropriate.
Good luck,

My mistake, When I looked it up, sig's website was down, so I got the info from another.

There is another significant difference though Mike, the Citabria had a flat bottom wing while the SD had a semi-symmetrical wing for better aerobatics.
True, and the Sig has a flat bottom wing, while the Midwest has a Semi-Symmetrical wing.
Another reason to go with the Midwest.
Plus (and I am just guessing here) the Sig is one of their older kits. Many of their older kits are "Builder's kits" which, in my book, is another reason to avoid this one (unless you LIKE builder's kits)
