Hi Ron,...

I had the same thoughts as you,... I wanted to use a Hammer 40 (or even enlarge it to 60 size) for pattern competition. A fellow club member had the Hammer 40 and raved about how nice it flew. Having never flown the plane myself I had to take his raving with a grain of salt. Don't get me wrong,... I have no doubt the plane flew nice; however could it be competitive in pattern??

In any case,... I enlarged the plans to a 68 inch wing span and I was planning to stretch the fuselage six inches or so to balance the weight of the OS 91 Surpass that I was going to install in the front. However the project never materialized.

Let me know how you make out with your Hammer 40. What engine are you planning to use?

Sincerely,
Steve T.
