1. Mark the forward and aft C.G. limits on both sides of
the bottom of the wing 2" and 2-1/2" [51mm and 64 mm]
back from the leading edge where shown—using narrow
strips of tape will allow you to feel the marks when lifting
the model with your fi ngertips to balance.
2. Install the battery, battery hatch and cabin hatch. At
this point the Beaver must be in ready-to-fl y condition with
everything attached and installed including the fl oats or
wheels and battery and propeller.

4. Lift the model by your fi ngers between the lines
indicating the balance range. As long as the Beaver sits level
with your fi ngers on the forward or aft lines or anywhere
between the lines it is properly balanced and ready to
fl y. If you have to move your fi ngertips outside the lines
the Beaver is out of balance and should not be fl own. If
necessary, add squares of stick-on lead to the nose or tail
to get the Beaver to balance within the specifi ed range.
When powering up, make sure the throttle stick is in
the minimum (0%) position. Always turn the transmitter
ON before plugging the battery into the plane.
The Beaver fl ies mostly the same as any similar-type, high-
wing airplane, but you may fi nd that the roll rate is a little
slower. This suits the Beaver well as it is a scale-like, STOL
(Short TakeOff and Landing) craft. Just give yourself more
time and altitude before trying your fi rst full roll.
The only peculiarity arises when the fl aps are extended—if
you extend the fl aps too soon before the Beaver has lost
enough fl ying speed the nose will pitch up. The way to avoid
this is fi rst by making sure you have given the Beaver enough
time to slow after cutting the throttle. You can also roll in
the fl aps gradually. If you have a computer radio you could
also mix in some down elevator with fl aps. In any regard,
once the Beaver reaches "equilibrium" and has initiated a
gliding descent the nose will resume a normal, downward
glide angle. Similarly, when powering up the throttle with
the fl aps extended the nose will pitch up, so be ready to
counter with down elevator.
Taken verbatim from our fl ight log book... "Flying the Beaver
from water with fl oats can be described with many adjectives
including astonishing, easy, fun, smooth, remarkable, etc."
Unless weather conditions are poor, you should have no
trouble fl ying the Beaver from either rough or calm water.
The water rudders direct the Beaver well and they don't have
to be perfectly centered to be effective (so don't spend an
exorbitant amount of time on the work bench working on
them!). The Beaver turns more tightly at idle speeds, so if
you need to do a U-turn throttle back to bring the Beaver
around. At higher speeds during a takeoff run the water
rudders have the correct amount of effectiveness to steer
the Beaver on its intended path. Takeoffs can be long and
graceful or short and steep—either way the fl oats handle
