Diagram #14
Use medium CA to glue the scale details, the exhausts, oil cooler and canopy top the fuselage.
Diagrams #15 CONTROL THROWS
*The suggested control throws are more than adequate for spirited roll rates, loops, and performance in
general. For less experienced pilots, we suggest that you set these on the “high rate” switches of your radio,
and do your first flights on “low rate” with the switches set for about 65~75% of max throws. Also some
exponential (30% or so) on elevator and aileron make it less sensitive.
Diagrams #15 - Center of Gravity (CG)
*The recommended starting CG is 90mm (3.54”) from the LE at the root. Do not fly the plane with the CG any
farther back than 95mm (3.74”). For first flight, 85mm may be best (3.34”).
*Keep in mind that the BF109 is a scale model, with higher wing loading than “park fliers” and many sport
electric aircraft. As such, maintain good airspeed at all times, and be sure that your landing zone is long
enough for approaches at 22~25 miles per hour. The BF109 is a real sweetheart to fly though, with excellent
low-speed handling and no bad habits…so don’t be nervous.
FINAL SETUP
*Install your receiver, motor, controller and battery as recommended by the manufacturers.
•
See Setting, Control Throws, and CG sections for recommended setup. Also check that the model is
balanced Right/Left (roll axis) and add lead weight to one wingtip if necessary.
•
Set your DUAL RATE LOW Switches for Elevator and Aileron to 60%~75% of recommended throws, and
use DUAL RATE LOW for the first flights.
•
Range Check your radio system before flight.
•
Have an experienced pilot confirm correct deflection of all control surfaces and proper CG before flight.
•
We’ve found it best to fly off of hard packed dirt, asphalt, or closely cropped grass.
