The Superflea is an EPP delta parkflier. It is quick and easy to construct and virtually indestructible. http://www.superflyrc.com/images/Flea,small.jpg

Specifications

  • Wingspan: 22 inches
  • Length: 17 inches
  • Weight RTF: 5.3 - 5.6 ounces

Construction

The kit contains a big block of EPP, hot wired into two wing halves, two elevons and a flat sheet of EPP from which you cut the fins and motor mounts using templates in the excellent instructions. The canopy is a block of EPP that you sand to shape. EPP sands easily with coarse paper (80grit) - only sand in one direction for best results. It is supplied unpainted but is easy to paint because EPP is not attacked by most spray can paints.

Power

The kit is powered by two GWS IPS motors with direct drive 3x2 props. a 2s 450mah-730 mAh LiPoly is recommended. A 2s730mAh lipo gives 10-20 minute flights (10 if you don't have a lipo safe ESC and are timing the flight)

A ducted fan version used to be available. This is faster and louder, has shorter flight times but was withdrawn because the fan units were not as robust as the rest of the plane.

Flying

The superflea was not designed for high speeds, it will do about 40mph (outrunning dogs in the park) but it's not going to scare other park users. Ideal flying space is about half a football pitch but it can be flow in a gym.

It is very easy to launch and has a good climb rate but less thrust than weight, so it won't go vertical. It's 'special trick', in common with all the superfly deltas, is that it can be flown at an angle of attack of about 60 degrees, at walking speed or below. This makes it very easy to land at your feet and not too hard to catch.

Rolls are easy if you have enough speed and can be very fast, however as the speed drops off it can get 'stuck'. Inverted flight needs fine elevator control. Loops are possible but it's easy to loose too much speed pulling up too sharply.

This plane is tough enough to be given to a complete novice, although they will crash every few seconds! It's possible to break the props if you leave the throttle open and crash inverted, but otherwise it's almost impossible to break anything. A top speed nose dive results in a big bounce and some of the paint flaking off.

With the control deflections reduced to about 1/4" each way, it's easy to fly but it won't fly 'hands off' - it will gradually roll off one way or the other.

This plane would be good for:

The superflea makes a good aileron trainer for an adventurous pilot. It's good for messing around in the park, very agile and responsive and most importantly, almost indestructable. It encourages you to try silly stunts and laugh when you crash.

This plane is not:

  • A trainer, it won't sort itself out if you let go of the sticks.
  • A speed plane, it doesn't have the power.
  • A pattern aerobatic plane - it has no rudder, little side area, and looses too much speed in aerobatics.

Modifications

The standard motors can be replaced with a single centrally mounted cdrom motor, with the prop running in a slot. This can give signficantly more speed and power while still protecting the motor from a crash.
