Jon's EHelis - Piccornet UH-1 Huey Attack Helicopter

The Concept:

I'd been wanting to add a Vietnam Era Huey to my fleet for a long time. So in February 2004, I purchased the Ikarus UH-1 body kit.

Initally the machine was built up as stock standard with FUN mechanics, as a stock review item. (See the Piccolo UH-1 Huey page for details on that machine).

After I had completed that mission, the bird was returned to the workshop for a full re-work.

First up, I stripped out all the FUN Piccolo gear, and went about modifying a Piccornet set-up to fit. This involved some changes in both the Piccornet side, and the Ikarus Body, to accomodate the Hornet CCPM setup.

Having done that, I then added the minor scale details (pitot, antennae, door handles etc.) prior to a re-spray in good old olive drab.

After the re-spray (thanks Rob!) I then built and fitted the weapons systems. The final touch was the cration and application of the various graphics to give the machine the right look.

The machines first outing was not auspicious, on the final flight of the night, my ESC decided to shutdown in flight, resulting in a nasty crash, with the tailboom ending up in several pieces. I've since re-built, and am now working on an alternative motive source.

This machine is very much a work in progess, with one of the lates editions being a change to Hornet II rotor blades, which with their longer length, and paralell chord give a very nice scale look to the rotors (no photos yet sorry).

This page will be updated as new pics, and changes in configuration occur.
