Just about got the hang of hovering my Ikarus
ECO Piccolo electric model helicopter. Designed for indoor use, or outside if
VERY calm. Flies for about 4 mins on the standard pack of seven AAA NiCads, though you can get
Tadiran Lithium Manganese Dioxide cells that do up to 17 mins. They're lighter too. The Tadiran cells and the special
chargers required are available from WES-Technik
and RCS Technik
The clever bit. One side of the electronics board consists of a standard mini
4 channel receiver (for main motor, tail and cyclics) and the side that we see
here has a little board with the piezoelectric gyro, two speed controllers (for
the main and tail motors) and a mixer. All straight rods and tubes are carbon
fibre. The blades are glass-filled Nylon.
Video (700KB, Quicktime) of me flying it in the bedroom. It's quite tricky in a small room
because you soon run into your own prop wash.
Fortunately it's been quite calm recently and I've been flying it quite a lot in the garden.
