42 inch wingspan

36 inch wingspan

Distinguishing features

Best for beginners.  Multi purpose flight including fun flying and slope soaring.

For pilots with intermediate experience. Offers aerobatic control and good low speed stable behavior.

For expert pilots. Highest performance aerobatic flight. Higher top speed, and considerably faster rolls and loops.

Additional required components and supplies

The following items are not included in the standard Unicorn offerings and must be purchased separately. Use this list as a shopping checklist. 

Qty

Item

1

Radio Transmitter with at least 3 channels; elevon mixing feature recommended (without elevon mixing, you will need to purchase an elevon mixer that you must install in the plane).  Transmitter “Exponential servo control” capability is desirable, but not required, for higher performance flight handling.  A new product from Hitec (www.hitecrcd.com), the Neon, offers promise as an inexpensive yet reliable transmitter.

1

Light weight receiver, dual conversion style recommended. Some recommended dual conversion receivers are:

2

Hitec HS81 Micro servos are recommended (approximately .65 ounces) or Hitec HS81MG (metal gears instead of plastic gears for impact damage resistance)

1

Battery pack peak charger.  You should choose one that can accommodate NiMH and NiCad battery packs, capacities from 600maH to 1650maH, and can recharge at least 8 cells.

An example is the Dymond Super Turbo Charger available at http://www.rc-dymond.com .
