Materials

Section One - Airframe/Motor Section balsa - three pieces 4" x 36" x V'. hardwood dowel - 1/8" x 36').

spiral wound paper tube - two p'ieces 3 7/8" diameter x

16V long available from Estes. motors - 8 " 0 " motors by Estes. ignitors - 4 Estes "solar ignitors". fireproof wadding - 1 piece Estes.

Section Two - Guidance Unit

R/C receiver, two servo units and an on board battery for missile. Compatable transmitter for ground direction. These units are available from numerous suppliers of R/C gear. Only two channels are needed. The two channel setups are available complete for as little as $75. Several frequencies are available. Any frequency will work but those within the CB radio range (27 MHz) should be avoided to eliminate the possibility of outside interference.

As a backup to the impact detonation system, a third channel may be added to allow manual firing of the missile. This type of system is known as C0M4AND DETONATION. NOTE: #2

If an airburst fragmentation charge is used, it will be necessary to use a command detonator type of system. NOTE: #3

A variation of this missile can be built without the control mechanism or movable trim tabs. Launch angle and point of impact can be figured with the tables and related information contained

In The Handbook of Model Rocketry by Stine or with the artillery range calculation tables available in many military publications. Trial and error will also be a factor in achieving accuracy.

• CONSTRUCTION INFORMATION

Section One - A1rframe/Motor Wings:

A. Glue two pieces of balsa, 36"x4"xVl together to 7orm a piece 36"x8MxJ«".

B. Cut this piece in half to obtain two pieces ^"xSW.

C. Cut these two pieces as shown in Fig.1. Note that one wing should have a 2V slot from point A to point B, while the other wing's slot is cut from point C

to B. The two wings will then fit together as shown in Fig.2. Test fit and disassemble for step D.

D. Cut a slot in each wing for the l/8"xl3M (Towel hinge. Note that the slot in one wing is offset 1/8" to allow the dowels to cross each other when the wings are assembled. See Fig.3.

E. Glue the four trim tabs to the two dowels and in-
