Average Skills Needed

The Peregrine Jr. is a downscaled model of the

4” dual-deploy Peregrine. Being smaller, it is easier

to transport and y, and expands the fun by ying on

smaller elds. With the smooth curves of the origi-

nal, it provides an excellent base for whatever design

ideas you may have. Moreover, the Peregrine Jr. is

equipped with a payload bay that can be used for

ying altimeters, eggs, and any other experiments you

may come up with. With all this exibility, it can be

successfully own both as a moderate-size eld ier

on D class 24mm motors or a performance rocket –

going over 2000’ with larger F class motors.

Construction of the Peregrine Jr. is easy, even with

the two-part basswood ns, allowing you to get it into

the air quickly. And with the rugged construction, you

can stay there – ight after ight.

Assembly StepsAssembly Steps

1. Remove the ns from the n sheet by cutting the

tabs with a hobby knife. Do not sand yet. Also, cut

out the bulkhead supports from the same sheet and

place it to one side for later.

2. Assemble the two pieces of each n as shown.

Ensure that the pieces align with smooth curves along

the whole exterior. Glue with wood glue and allow to

dry on a at surface.

3. Remove the cardstock centering rings and bulkhead

from the sheet. Remove the central notch in one of

the two rings; this will be the forward ring. The notch

allows space for the shock cord. Also cut a notch into

the green CR-24/29 centering ring. Set the bulkhead

(with the small hole) aside for later assembly of the

payload bay.

4. Measure ½“ (13 mm) from both ends of the 24mm

motor mount tube and mark with a pencil. Apply glue

around the tube at one of the marks and slide the ring

without a notch into place. This will be the aft (rear)

end of the motor mount assembly.

5. Tie the shock cord around the middle of the motor

mount tube. Pass the shock cord through the other

cardstock centering ring and glue the ring into position

at the second mark as shown, with the shock cord

pulled tightly behind the ring. Next, glue the green

centering ring in front of the cardstock centering ring

with the shock cord passing through the notch.

6. Using scissors or a hobby knife, cut out the tube

marking guide. Wrap it around one end of the 18” long

(BT-70) body tube and tape it in place so that it does

not slide. Put a mark for the location of each n and

the launch lug. Using a door frame or aluminum an-

gle, extend the launch lug line along the entire length

of the tube, and each of the n lines a minimum of 5

½” from one end, which will be the back of the tube.

Additionally, mark 10” (25cm) from the back of the

tube for the position of the launch lug.

7. Temporarily, route the shock cord through the center

of the motor mount tube so that it exits from the rear

of the assembly. Glue the motor mount into the back

end of the marked tube with the back edge of the mo-

tor tube ush with the body tube. Set aside to dry.

8. Fill any gaps in the assembled ns using a wood

ller or modeling ller and sand smooth up to 320 grit

sandpaper. To make later nishing of the complet-

ed rocket easier, the ns should be smooth prior to

installing them on the body tube.

9. Mount the ns on the marked lines. The root of the

n should be ush with the back of the body tube.

Glue with wood glue, making sure that the ns are

perpendicular to the body tube and aligned with the

long axis of the rocket. Use of a n alignment guide, if

available, is recommended.

10. Using wood glue, attach the launch lug along the

line above the mark 10” (25cm) from the bottom of the

body tube.

11. Cut a length of the Kevlar shock cord (roughly 8”

long) to act as a loop on the payload section and tie

a loop in the middle of it. Then tie the remaining tails

around the center of the bulkhead support piece that

was set aside in the rst step. Pass the loop through

the hole in the center of the cardstock bulkhead, and

using wood glue, glue the loop and support to the

bulkhead (also set aside earlier).

12. Mark the red coupler tube at the centerpoint (2” /

50.8mm from one edge). Then install the bulkhead as-

sembly into the coupler tube, approximately ¼” (6mm)

from one end with the loop facing out and add llets of

wood glue on both sides of the bulkhead.

13. Glue the coupler assembly into the unmarked 7½”

(BT-70) tube inserted up to the mark, with the loop

facing out. Then set the payload section aside to dry.

14. Apply a bead of glue along the base of the ns and

launch lug and wipe it off with a nger to produce a

smooth rounded llet. Leave the rocket to dry horizon-

tally to avoid drips.

15. Thread the shock cord back through the motor tube

and out the front of the rocket. Optional Step: If using

a screw-on motor retainer (not included), glue on the

threaded portion of the retainer by applying thick CyA

glue to the outside of the motor tube and then sliding

the retainer on until it bottoms out on the tube. The

screw-on cap can be put on after the glue sets.

16. Tie the shock cord onto the loop on the payload

section and insert the nose cone into the open end of

the payload bay. Ensure that the nose cone ts tightly

into the payload tube so that it cannot come off during

ight. Wrap the shoulder with tape as necessary to

achieve a tight t.

17. Cut out the plastic parachute using scissors or a

hobby knife at the 24” size (following the inner lines).

Then place one reinforcement ring on each of the

corners and poke a hole in the center of each using a

sharp knife or other pointy instrument.

18. Cut the provided string into four equal lengths by

folding in half twice (as shown). Tie the shroud lines

through adjacent ring holes. Place a small amount of

glue on each of the knots and set the parachute aside

to dry.

19. After the glue has dried, place the parachute top-

side down and lift the shroud lines one at a time near

their center, stacking them over a nger. To ensure

orderly deployment of the parachute, keep the shroud

lines well organized. Pull from the center of the para-

chute to even out the lines. Thread the four looped

ends through the loop on the payload bay, pass the

top of the parachute through the loops in the shroud

lines and then pull the parachute to tighten the knot.

20. When all the glue has dried completely, the rocket

can be painted.

21. Allow the nal coat of paint to harden for at least a

full day (24 hours) before applying the vinyl decals. Af-

ter removing from the paper backing, dip the decals in

water with a little dish soap added to allow the decals

to be slid around the rocket. Keep the decal wet until

positioned, then press down rmly and squeegee out

the water beneath it. Once completely dry, the decal

will be permanently attached.

22. And that’s it, your Peregrine Jr. rocket is ready

to y!

Display Stand AssemblyDisplay Stand Assembly

Remove the display stand pieces from the laser-cut

sheet. Assemble the three leg pieces by sliding the

tabs into the matching slots to engage all of them at

the same time. Place the small disk on the bottom.

Then make the assembly permanent with a thin bead

of glue along all the joints. The stand can be painted

once the glue dries.

To launch your rocket you will need:

●A launch pad with a ¼” (6mm) launch rod and a launch

controller that can handle the selected motors

●Recovery Wadding

●Engines such as those recommended in the motor

chart.*

Jr#motors

 A. Crumple and insert 5 or 6 sheets of recovery

wadding into the tube, push them to the bottom with a

long dowel.

 B. Fold the parachute so that the shroud lines all

come together, then place the shroud lines onto the

parachute in a loop and fold the parachute in half long

ways to surround the shroud lines. Fold the para-

chute again – this time the other way – to shorten the

whole package and insert rst the shock cord and

then the folded parachute into the rocket. Slide on the

payload bay.

 C. If you are launching with Estes engines, create a

thrust ring by wrapping 5 layers of tape over about ¼”

(6mm) of the end of the motor. Trim the excess tape

off with a hobby knife.

D. Install the motor by sliding it into the motor mount

tube and wrapping tape around the thrust ring to

prevent the motor from blowing out. Optionally, if a

screw-on retainer was used, screw the outer retainer

cap into place.

E. Insert and secure the igniters as directed in the

engine’s instructions. Place on the launch pad and

connect the clips to the igniter.

At this point the assembly of the rocket is complete

and the rocket is ready for ight. Continue to follow

the countdown and launch procedures.

Countdown and Launch ProcedureCountdown and Launch Procedure

Misre ProcedureMisre Procedure

The Peregrine Jr. is a light rocket that can y to impressive heights with D and E class motors. The rst ight should be

done at a large eld and in light winds to reduce the chances of losing it. The area around the launch pad should be

free from dry grass and other re hazards, and the pad should be as far from trees, powerlines and low-ying planes as

possible.

7. Remove the safety key from the launch controller.

6. Place the rocket on the launch pad. The rocket should slide freely along the rod.

5. Attach the clips to the igniter wires. The clips must not touch either each other or the metal blast deector.

Otherwise, a misre is likely.

4. Stand back from the rocket as far as the launch wire allows (a minimum of 40 feet for motors E or larger).

3. Insert the safety key to arm the launch system.

2. Give a loud countdown! 5… 4… 3… 2… 1… LAUNCH!

1. Press and hold the button until the engine ignites. Once the rocket is away, remove the safety key.

A misre is when an engine does not light after the launch button is pressed. This is sometimes a result of the igniter burn-

ing but failing to light the engine. At other times, the igniter will not burn at all (this is often indicative of a short between the

clips). To deal with a misre safely, remove the safety key from the launch controller and wait a full minute (60 seconds)

prior to approaching the pad. Check that the igniter wires or clips were not shorted together. If they were, the short can be

corrected and a launch attempted again. If the engine simply failed to light, remove the old and install a new one. Make

sure that the igniter is installed all the way into the engine and that it is in contact with the propellant. Always follow the NAR

(National Association of Rocketry) Model Rocket Safety Code when launching model rockets.
