RE: A Bit Of Cox Nostalgia On The Tee Dee .010
That .010 IS a powerhouse. I bought one in 1963 and put it in a Top Flite Rascal 27 with an F&M Pioneer reciever and a citizenship SN escapement. As fast as I could handle back then, and great climb.. In fact, on the last flight, I realized too late that I had forgotten to rewind the escapement rubber, and the plane climbed out of sight.
I have one of the newer engines on an old Enterprise FF bipe. The plans show the plane flying on an old Spitzy 045. With the .010, the plane is a corkscrew under power, even running rich with the prop on backwards. I've seen this plane fly with the Pee Wee 020, with far less trouble.
