Steve, I laid a set of US 40 plans over the Hammer plans and both planes
have basically the same layout. The Hammer has a thinner airfoil but more
area, so it may fly about the same as the US 40. Just hope that someone here
can give some info on it’s ability.

As for which engine I may use. I’ve got this thing about adjustable engine
mounts, so I may move the firewall back some, install on of these mounts and
play the switch engine game. I may go with my old OS 50 FSR, a Magnum 53
or just for overkill a MDS 58. I have a couple 4 strokes I want to try also.

I was thinking the same as you, as soon as I looked the plans over. This
would be a good plane to up size or even rework into a new or older design.
As it is, with a little of this and that it could easily be modified into a number
of the older designs and stay with a 40-45 size engine. I was thinking about
something like a 45 size Tipo, a want to be Brushfire or one of the Phoenix
myself. Being that you said you had already enlarged the wing, I also laid a set
of Bridi Escape plans over the Hammer plans. You could come up something
real nice using the Escape measurements. But a 60 size Hammer with enclosed
pipe sound’s real good too.
