threaded end of the pushrod. With the elevator servo
centered, mark the location for the required

"Z-bend" in the pushrod. Make the "Z-bend", attach

the output arm to the pushrod and then to the servo.

4. As shown on the plans, the throttle pushrod is

plastic tubing with a 6" threaded wire and "Z-bend"
at the throttle servo end and a 1" threaded stud and
kwik-link at the carb end.

5. There is a gauge fixture provided on die-cut sheet

RC-34-2. This gauge, as shown on the plans, is used

to set the flight surfaces for neutral trim. DO NOT AT-

TEMPT TO SET NEUTRAL TRIM ON THIS AIRPLANE

USING ANY OTHER METHOD. With your radio on,
use this gauge and the adjustments available to you

through the clevises to set the ailerons and elevator
to neutral. Adjustments should be made either
mechanically or electronically (through your radio)

for the following flight surface movements:

Ailerons.. .... 3/8" up

3/8"down

Elevators. .....3/4" up

3/4" down

Remember what was said earlier about the use of
Monokote hinges—they will make the flight sur-

faces about 25% more effective.

6. Note on the cross-section of the landing skid that

the skid itself is bent back at an angle. You should do
this now. The angle should be about 20 to 25
degrees. You should also bend the ends of these to a

"half-round". You might consider adding small

wheels to these skids by bending out an axle at the
ends, slipping on the wheel (1/2" to 3/4 "dia. would do)
and soldering a washer in place as a retainer. If you
fly off of a hard surface, wheels might be easier on
your ears. Mount the skids in place on the bottom of
the wing.

7. Adjust the nose gear steering arm and/or clevises for

neutral.

8. Install the fuel tank, fuel tubing, engine and muffler.

Make all necessary fuel connections and throttle

hook-ups.

9. We have found it convenient to install both the

receiver's switch harness and charging receptacle

directly to the radio hatch cover. Wrap the reciever
and battery pack in foam and install in the radio com-

partment. Button-up the hatch cover and, assuming

that you have already mounted your 2-1/4" dia. nose
wheel, you should be ready to balance the airplane.

10. Balancing this airplane at the point shown on the

plans is very important and should not be.
underestimated. The design is very pitch stable

when balanced at this point. Much can be done to

move the Center of Gravity fore or aft; a plastic spin-
ner is lighter than a metal one and no spinner is
lighter than both, battery packs can be moved as far
back as W-10 and the throttle servo could be reposi-

tioned next to the aileron servo, etc., etc. Once the

balance has been achieved and your engine com-
pletely broken-in and reliable, you can head for the

flying field.

FLYING

This is the part all of us love and fear at the same time.
The Holy Smoke 40 is not too much different than most
aircraft in that all of the homework must be done before

lift-off. Since it isn't reasonable to ask you to test-glide

this airplane over tall grass, we're going to assume that
you did indeed follow the fore-going instructions.

Because if you did, then the test flights should be almost
routine.

We say "almost" because unless you are told ahead of
time, like right now, you could be in for a surprise or two.

First of all, the take-off. The take-off will be quick; be

ready for it. There is some tendency for the airplane to

torque a bit to the left due to its high power-to-size ratio;
be ready for it. For first flights we would suggest that you
have a helper hold the airplane on the ground, pointed in-
to the wind while you apply full power. Have the helper
release the airplane at your command. In this situation,

the airplane is "flying" in less than a few feet. Now that
you're up there and have things pretty well under control
you might be interested in observing the airplanes roll-

rate. Next you might want to observe the roll-rate while

climbing vertically—neat, huh? Our Enya CX powered

H.S. 40's will climb and roll out of sight, a maneuver

guaranteed to make you an instant "club pro"!

All good things must come to an end, even eight ounces
of fuel—time to land. Delta's can fly slowly with their
noses up just so long. At some point all of the up elevator
available will peter-out and at that point a stall is achiev-
ed. As mentioned earlier, deltas tend to stall straight
ahead and gently. Gently, however, is a relative term. At

200 feet, gentle is one thing, but at 10 feet gentle can be
something else. All of this is telling you to keep the
speed up on your approach to a landing. Our best lan-
dings have been done by maintaining about 1/3rd throt-
tle throughout the entire approach while steadily decen-
ding to the field. As soon as field threshold has been
reached, lower the throttle to full idle and flair to touch-

down. Don't worry that your first few attempts are a bit

bouncy; you'll get the hang of it soon enough.

The stunt repertoire of the Holy Smoke 40 is just about
endless. Even without rudder input, we've been able to

knife-edge from one end of the field to the other on sheer
speed.

We sincerely hope that you've enjoyed this project and
that your Holy Smoke 4 0 will indeed become your perfect

"other airplane".
