Jacob (12) on his left. This is the first plane
James has ever flown and he completely
soloed on his fourth flight. He thought he was
ready earlier, but Dad was nervous, not him. Do
you get a sense of how great this trainer is?
I have flown this as a glow model and was not
really that impressed. The ultra-light wing
loading produced an aircraft that wallowed through
the air and was no fun at all in Nebraska wind. As
an electric and with 20 cells of "ballast", this
thing flies absolutely beautifully. Very solid
handling yet light on its feet for landings. It
will do very large loops from level flight.

by my good friend Bob Roegge whom I worked with at
Offutt AFB. He said it was simple, but I say he's
a gifted builder. (Photos and text by

relative size. No shrink
helps cooling and allows the gaps between the
cells to seat on
triangle stock in the battery tray so you can
shift forward and aft for CG
adjustment. The Velcro then holds it down and
keeps it from shifting. I've
since gone to shrink wrapped 20 cell packs that
work very well.
