Sig Hummer

Archie “Lynn” Sipes (1948-2004)

The following pictures are of a Sig Hummer built for the late Lynn Sipes of Bolivar, TN. If you ever visited the 1/2A forum at RCUniverse you would surely have run into Lynn. I never met him personally but had the fortune of building several of his airplanes for him. He was a pleasure to deal with and will be missed. The Hummer was the first of three planes that I built for Lynn, the other two being a 1/2A SST (pictured above left) and a Stinger 10. The Hummer is a joy to build and only takes about three evenings to get into the air. As you can see in the pictures, I used monokote hinges for the control surfaces. Monokote hinges are my favorite for aircraft up to about .40 size. They are tough as nails and provide an automatic hinge gap seal. If you have any questions or comments concerning the construction of the Sig Hummer please feel free to email me.
