Hangar 9 P-51 PTS Mk II Assembly Manual
Once the flaps have been set, slide the clevis retainer onto
the clevis to keep the clevis from opening accidentally.
Graduate
Once you are comfortable soloing your P-51 PTS Mustang
in this configuration, you’re ready to graduate to advanced
flight and aerobatics. The last step is to remove the clear
anti-spin NACA Droops. This is done by simply removing the
clear tape on the top and bottom that holds them in place on
the wing. With the Droops removed, your P-51 PTS Mustang
is now an all-out aerobatic warbird. Have your instructor
nearby for the first few flights.
The P-51 PTS Mustang will now descend more quickly and
land faster like a sport model. In the air, you can now do a
variety of aerobatics such as rolls, loops, spins and snap
rolls.
The droops are held on with clear tape. Simply pulling the
tape will allow you to remove the droops. Save the wing
droops in case you may want to use them for training a
budding fellow pilot in the future.
Hint
: The glue residue from the clear tape can be
removed with isopropyl alcohol or CA accelerator or
paint thinner. Always test solvents in an inconspicuous
place to make sure they will not damage the covering of
your model.
After you have graduated from the Progressing Training
System and are enjoying your P-51 PTS Mustang in its
aerobatic mode, you can take it even a step further and add
functional flaps. To do this, you’ll need to purchase two
additional servos from your local hobby shop such as the JR
SPORT ST-47 servo and a Y-harness. Then, simply remove
the cover over the flap servo in the bottom of the wing
and install the servos. Hook up the linkages to the servos
following the directions and you have a scale P-51 PTS
Mustang complete with functioning landing flaps.
