Jack shared his technique for glazing the cockpit panes on his Bv 141.
Blohm und Voss Bv 141
by Gene Smith
Jack Kacian’s Blohm und Voss Bv 141 was built from Al Lidberg plans that Jack acquired roughly 20 years
ago. I have a 20-year-old set of those
plans myself! Jack found out that Al was
offering a short kit of the laser-cut parts
he needed to get started.
Jack said the greenhouse crew
compartment was definitely the toughest
part. The structure itself wasn’t bad, but
the glazing took several tries to achieve
satisfactory results. It was one of those
“if I had known then what I know now”
Jack started with regular plastic food
wrap adhered with glue stick, but could not get all of the wrinkles out. He settled
on a method that allowed him to cover several sections of canopy with folded clear
Jack used Glad Press’n Seal, a plastic wrap with a mild adhesive on one side, to
make a pattern. First pressing a piece over an area that could be glazed in one piece,
he marked all of the corners and creases on the Press’n Seal. He then peeled it off
of the model and pressed it onto the clear plastic sheet using the marks to cut and
crease the plastic sheet as needed. This should result in pieces that fit perfectly!
Jack attached the glazing with small dots of CA glue. The tissue used to simulate
the framing was painted and preglued with glue stick on a sheet. The framing strips
were cut from that sheet then attached by activating the adhesive with isopropyl
The covering was painted with the splinter camouflage, markings, and control
surface outlines before being applied to the model, except for the motor fuselage.
That was painted after covering in order to align the camouflage lines. Jack used
airbrushed Tamiya acrylic paint.
The model’s empty weight is 60 grams. The motor and ballast, at approximately
75 to 80 grams flying weight, brings it to approximately . 5 grams per square inch
Bill Schmidt has an interesting approach to freewheeling propellers. I had not
noticed until recently that his freewheeling propellers are set up like folding
More than 20 years ago, Bill watched Jim Lehrman’s Gollywock land on a hard
runway. As it touched down, it broke off one blade. The model bounced up off the
pavement, descended again, and broke off the other blade. Bill decided that the
only time he would ever have a rigid propeller was if the model required a Peck-Polymers propeller.
When he first started using folders on freewheeler models, he put 1/2-inch modeler’s
pins on both propeller blades and put small rubber bands across the two pins to
maintain the propeller in the forward position, but with shock-absorbing qualities.
He found that this rig was unnecessary because the propeller remained
dynamically in the forward position
throughout the glide. Bill discovered
that as long as there wasn’t a stop on
the back of the noseblock, the propeller
blades would stay extended during the
glide as if they were rigid, one-piece
The Long Flight
Bob Clemons wrote a great story
about his Baka Bomb No-Cal’s final
flight. Near the end of the first day of a
past Great Grape Gathering contest in
Geneseo, New York, Bob debated about
which event he might be able to squeeze
in before the meet closed at 5 p.m.
He decided to fly his No-Cal, a 16-
inch wingspan Japanese Ohka he built
from George Bredehoft plans. Originally
built for Indoor flying, it was slightly
heavy to be competitive, but was still a
bit light for outdoor use where a more
robust airframe would be needed. Bob
beefed it up so it could better cope
outdoors in all but a strong breeze.
At this point in the meet, Vic Nippert
had a commanding three-flight lead “in
the clubhouse” with a 462-second total.
There is no max in this Flying Aces Club
event, which calls for a three-flight total
for scoring. Bob thought he might sneak
in for a second or third flight and win a
bottle of wine.
