Blitzer Assembly Manual

FLYING:
Most companies will recommend that you test glide your model prior to attempting powered flight.
Unfortunately with most war birds such as the Blitzer, that is not a practical option.
Test flights should be made by an accomplished pilot with a good, firm toss. Grip the model behind the
wing at the bottom of the fuselage. The toss should be slightly upward with the wings level and full
power.
Depending upon the motor you selected, the plane may take a second or two before the prop bites, but it
has been successfully flown away from some really terrible launches. At low speed the ailerons are not as
effective as you might like, so it is very important to have a level-wing launch. The maiden flight of the
first prototype used a Mega 16/15/4 and a Graupner 6x3 folder. The plane almost jumped out of the
launcher’s hand!
As soon as the prop bites, the Blitzer will accelerate rapidly and will quickly climb to altitude. Trim the
plane for straight and level flight at full power, then reduce to ¾ power get a better feel. It should track
very well with little or no trim changes across the power range.
In flight, the plane is capable of loops from level flight and high-G turns. Rolls are predictably non-axial
due to the low wing, and the roll rate is impressive at full deflection. The elevator is very sensitive.
After you have several flights in, you may want to play with the expo settings and the propellers. A
variety of props have been used. My favorite is with a 6x3 or 6x4 folder, although props as small as
4.75x4.75 have been used with Speed 400 6V motors. Yes, it will fly on them and fly well!
Enjoy, and don’t forget to send us photos, videos, and e-mails about your Blitzer!
