This is my "Keith Paskewitz" IFO. This
is my latest attempt to build a lighter plane. It is
all new with a lighter carbon fiber frame, cases taken off
the servos, carbon fiber servo arms, wire cut to exact
length to save weight etc. I also used 2mm Depron
instead of 3mm this time and used pull-pull system using
button thread which is strong and not very stretchy. I
used ink which I sprayed with an air-brush to paint the
plane. Ink has no fillers and colors with very little
My first IFO was 11 or 12 ounces. I later changed to
outrunner motors and lithium battery and cut the weigh to 8 oz.
I then put a controllable rudder on it. I later
redesigned the rudder two times. then I added a second
landing gear on the top so I could land up-side-down.
By going to lighter batteries etc. I managed to keep the
weight at 8oz.
I then took one of my two IFO's and stripped it to just the
bare frame with the ripstop covering still on it. I
went to lighter equipment. I used a 14 gram E-flite
250 motor, Spektrum Nanolite airborne with 2 gram receiver
and 6 gram digital servos, Dualsky 300 mah 25 C 21 gram
batteries and lighter weight GWS 8x4 prop. This
brought my weight down to 5 1/4 oz.
When I first started day-dreaming about building an IFO
substantially lighter than the 5 1/4 oz. one I didn't think
I could actually do it. I was really thrilled when it
came out at 4 oz.
I will now go thought a debugging process and fine tune it.
I just changed to heavier carbon fiber for the elevators
which added 2 1/2 grams. they where too
flexible before. I well have to move the servos forward since it
is tail heavy.
