That four star 60 may not be bigger than your alpha, but it's about 3 pounds heavier and about 30 mph faster. Keep the rates low for the first few flights and enjoy! I just built my second, it's the plane that always makes the trip to the field!

What were you planning for an engine? If you can swing it $$, a .91 four stroke is a nice match. A 75 two stroker does a good job too.
