REQUIRES: Park Flyer Aircraft
          A .050" hex wrench to tighten the pinion set screw.
          A 1.5mm hex wrench to tighten the prop adapter set screw.
          Small phillips screwdriver

SPECS:    See individual item descriptions for further information.

COMMENTS: This same system is also available with-out the electronic speed
            control, use GPMG0415.
          Instruction sheet includes a cross-sell ad for the Hobbico C5 nano
            servos. This is JUST A CROSS SELL.
            Fundango, the model around which this package was designed,
            DOES NOT use C5 nano servos. It uses mini servos such as the CS35.

   TECH NOTICE FUNDANGO/FUNDANGO POWER SYSTEM USING the 1.7:1 Gear Box:
Improving the performance and preventing damage to your system.
1) The gear mesh is Critical. Set the gear mesh by running a sheet of notebook
     paper between the gears. It should and will feel sloppy. If the gear mesh
     is tighter than this the motor will OVERHEAT (60 degrees hotter!) and
     immediately lose performance. If you have already run your motor with
     this tight gear mesh and performance is lacking, please send us the
     problem motor with a copy of this tech note and we will replace it at
     no charge.

2) Oiling the motor's shaft: This is a part of normal service of most
     electrical motor components which was accidentally left out of the
     instructions for your power package.
   Please apply one drop of lubricating oil to each end of the shaft. This will
      also dramatically increase the motor's performance.

3) Balance the prop and centering the prop are CRITICAL. Being off even 1/16"
      will cause a wobble which robs nearly half the available thrust from your
      motor combination.

If options 1 through 3 did not solve your performance concerns (acceptable
  being flight times of 3-5 minutes with sufficient power for the model to
  climb comfortably at a 45 degree angle). please consider:

4) Prop/Gear box match. The 1.7:1 gearbox works well on the Fundango for most
      modelers as is, but for some, the performance is increased by using a
      9x6 prop. The 3:1 ball bearing gearbox, GPMG0225, does also offer an
      increase in performance when using the 10x7 prop already provided with
      the power system you previously purchased, or an 11x7 with even more
      power system you previously purchased, or an 11x7 with even more power
      but shorter run time.

  If you have tried options 1 through 4 and performance remains unacceptable,
    please mail us your motor/gearbox combination for warranty consideration.
