The control measurements listed above should give full aerobatic capability if your Spacewalker is properly balanced. Test
flights may indicate a need for more or less movement, depending on individual model performance and personal
preference.
NOTE: If you have built your Spacewalker with the short (4-bay) ailerons, increase the throws given above by another 3/8"
in both directions.
Balance your model somewhere in the C.G. (Center of Gravity) Range shown on the plans. For test flights it is better to
balance in the forward portion of the range than in the rearward portion. Add weight to the nose if necessary - trying to fly
with the C.G. too far back is much more dangerous than the slight increase in wing loading caused by adding lead to the
nose!
FLYING
The Spacewalker has proven to be one of the most exciting models that we've ever flown. Although it will perform the full
range of aerobatic maneuvers, it will settle down for slow, stable landing approaches and touchdowns. It's a fun and easy
aircraft to fly, but it is not a basic trainer. Do not attempt to fly your Spacewalker unless you've logged some flight time on
other low-wing aircraft. Have an experienced pilot assist you, particularly on test flights.
In the air, you will find the Spacewalker to be very smooth and stable. It's aerobatic capabilities will definitely please any
sport pilot. After the model has been trimmed and you are more familiar with its flying qualities, you may want to
experiment with slight changes in control surface travel and balance point until the model flies and reacts just the way you
like it. Advanced pilots who are striving for maximum realism and smoothness should "coordinate" their turns by adding a
small amount of rudder at the same time, and in the same direction, as the aileron. Many of the newer radio systems offer
a "coupling" feature which will automatically deflect the rudder slightly when you use the aileron stick. We have used this
feature successfully on our Spacewalkers. The proper amount of rudder movement is about 3/4" each direction with full
deflection of the ailerons.
When the time comes to land your Spacewalker, remember to keep your control inputs smooth and gentle to avoid
overcontrolling. When you are certain that the model will make it to the runway (even if the engine quits), bring the throttle
to full low and concentrate on keeping the wings level during final approach. Slow the model down during the entire
approach by slowly feeding in up elevator. Just before the model touches, flare the landing by carefully feeding in more up
elevator. Hold the model just inches off the ground until your elevator stick is pulled all the way back. The Spacewalker
should settle down to a perfect "threepoint" landing with a short rollout. Taxi back slowly and graciously accept all the
praise offered by onlookers. Your Spacewalker will surely be the hit of the flight line!
