Sig Senior mods, upgrades
I just built a Senior from plans for a good friend of mine. I did most if not all of the mods mentioned above. He will be powering it with a TT PRO46. If you want to make some serious mods to the Senior do like I did and build it for floats. I built my second Senior for use as a float plane. Unfortueatly I havn't gotten to use it yet. I may have to take the 91 off and find a nother project if I don't get to float fly this year.
I built my original Senior stock and powered it with a TT GP42 like Tom. I really enjoy that plane. It is truly a relaxing plane to fly. I would guess that since I built it in Sept 2001 I probably have well over 150 flights on it and I tought my son to fly with it. I;m considering swaping out the 42 for the extra PRO46 I have sitting in my shop so that I can fly off grass a little easier.
Another neat mod would be to make it a twin with 2 gp42's sitting on the wing.
Happy building.
