The Superfly is an EPP delta park flier. It is quick and easy to construct and very tough. http://www.superflyrc.com/images/Superfly,small.jpg

Specifications

  • Wingspan: 27 inches
  • Length: 22 inches
  • Weight RTF: 10.9 - 11.2 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 using templates in the excellent instructions. The canopy is now hot-wire cut EPP that can be used as it is in the picture or sanded to a more rounded shape. The kit is supplied unpainted but is easy to paint because EPP is not attacked by most spray can paints. Hot glue is recommended for constructing this kit because it's very fast and tough. Contact adhesives can also be used but need to be left for a while to reach full strength.

Elevon hinges are made from a smeared bead of hot glue. Superfly developed this technique and it works extremely well, although a little practice is recommended.

Power

The kit is powered by a 2408-21 bell motor with a GWS 8x6 prop. 2 cell 1200-1500 mAh LiPoly is recommended for 10-20 minute flights. A 3 cell battery and 8x4 prop are a great upgrade, giving plenty of thrust for vertical flight and great 'punch' out of high-alpha flight.

Various brushed versions used to be available but were withdrawn because the brushless version is better in nearly every way (the exception being that it can't scoot along the floor).

Flying

The SuperFly was not designed for high speeds or for precision aerobatics but it's great fun. Ideal flying space is about a football pitch but it can be flow in a gym.

It is very easy to launch and has a good climb rate. 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 or below walking speed. This makes it very easy to land at your feet or to 'hover' against a light wind.

The SuperFly is a great plane to fly on a windy day, relatively unaffected by gusts, fast enough to overcome most winds and tough enough to handle bad landings.

Rolls are easy if you have enough speed and can be very fast. Inverted flight needs fine elevator control. Loops are possible but it's easy to loose too much speed pulling up too sharply. The extra power of the 3s battery makes large loops easy and rolls are less likely to get 'stuck'.

This plane is not as quite as tough as the SuperFlea but it's still extremely tough. Most crashes just result in a bounce, but with higher power it's possible to break the nose off - this can be fixed with hot glue in minutes.

With the control deflections reduced to about 1/2" 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 superfly is ideal for messing around in the park, very agile and responsive and most importantly, tough. 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, even with the 3s battery the motor and prop produce more thrust than speed.
  • A pattern aerobatic plane, it's hard to fly large accurate figures.
  • A 3D plane - even though there's enough power to hover it has no rudder and little side area, so it won't fly knife edge.

Modifications

You can run strapping tape along the leading edge to make it even tougher.

You can add a rudder - twin rudders on the stock fins don't do much but a single central rudder helps steering at low speed.

Velcro straps are a useful extra for securing the battery, which can rip the canopy off.
