Top Flite TOPA0220 - Manual (Page 5)

Radio installation
The radio installation can be as simple as five standard
servos - or as challenging as seven servos that must be
fitted in a confined space. Pay very close attention to the
instructions and it will all fit easily. Drift off on your own
if you want, but be prepared to spend a lot of time
getting things to fit properly.
Nose heavy/Tail heavy
Most models require some nose weight to balance
properly. This one requires tail weight! The built up
tail feathers are light yet very strong. The tail is also
very short, resulting in a model that is slightly nose
heavy. If you power the model with a .46 size glow
engine you will need about 1 oz of lead on the tail.
Engine size
This model can be flown on a .25 size engine, but -
why. With an O.S. .46 FX, nine servos and retracts
the model weighs close to 5-1/2 lbs. That gives a
wing loading of 23.0 oz/sq ft. The engine will produce
more than six lbs of thrust if it is properly broken-in.
Think about those numbers for a minute.
Start building! Build light!!
