BLITZ
Sport $22.00
Extra Wing $10.00
36"
wingspan, 8" Chord with Ailerons, 25-30 oz. flying
weight. 2 to 6 hours to build this low cost, high excitement
kit! This foam kit uses a proven design and a great symmetrical
wing (SD8000 airfoil). Excellent for a R/C pilots who are
buying their 2nd plane, although experts will love the zippiness
of this kit. Lots of thrust when equipped with Colbalt or
Mega Brushless. The Blitz will fly with direct drive or
gear box. Our most fun so far has been direct drive with
a 6 x 5 APC prop. Requires a 3 or 4-channel radio for ailerons,
elevator, rudder and throttle. Rudder is optional, so a
low cost 3 channel radio would work great. Our sample planes
use generic 9 gram servos, but could use larger HS-81 class
servos.
Nearly
idential to the regular Blitz except the fuselage is a bit
taller, giving more room for the battery, esc, and receiver.
(We liked they extra space). Easier battery insertion and
removal. There is a slight increase in material costs, so
this plane is $2 more. Requires a 3 or 4-channel radio for
ailerons, elevatorand throttle (optional rudder). Rudder
is optional, so a low cost 3 channel radio would work great.
Our sample planes use generic 9 gram servos, but larger
HS-81 class servos are the best all around servo.
Wattage
Cobalt works well, but we wanted to try the Kyosho Magnetic
Meyham (Forward rotation version) for this kit. This motor
is heavier, but makes up for it with more RPMs and a higher
top speed. Receiver and ESC mounted under cockpit windows.
Battery pack located after of that position.

This
is a Semi-Kit. These are the materials you will need to
complete this kit and must be purchased separately
Radio: 3 or 4 Channel, 2 to 4 servos depending
on builder preference. HS 81 size servos. Best method is
to use 2 aileron servos mounted in the wing, and one elevator
servo mounted near tail.
Wood: 1/8 sheeting for control surfaces.
A hardwood spar is need to stiffen the wing. Use 1/4"
x 1/2" x 36" Spruce stick. Optinally, 1/16"
balsa sheeting to glue on sides of the fuselage.
.
Motor: Wattage 400 Cobalt works will direct
drive with 6x5 APC prop. Some builders have used Speed 400
motors, geared 480s, and Mega brushless. Colbalt 400 is
about $35.00 and is a reasonable balance between performance
and cost.
Battery Pack: 8 Cell, 1700+ NIMH AA cells that can deliver
25 amps +. Sanyo 4/5 AUP 1700NIMH are perfect for this plane.
Controller (ESC): Depending upon motor.
For Colbalt 400, need at least 25 amps.
Covering:
Fiberglass strapping tape (about 10 feet), 2 rolls of different
colors of 2 mil packing tape OR 2 different colors/rolls
of iron-on covering. Econokote and Towerkote work well.
Ultracoat is heavier but is supposed to work as well.
Misc hardware: Control Horns, and Linkage
for the Servos. Try to use 1/2 A or Micro hardware as full
sized hardware is unnecessarily heavy.
1/16 balsa sheeting to glue on sides of the fuselage.
Adhesive:
Many glues workwell, these are some of the more popular:
Elmer's White Glue, 5-6 minute epoxy, Gorilla Glue, Hot
glue gun
Misc tools: Yardstick, Extra soldering
iron for cutting hatches in the foam fuselage.
