At long last the weather has been calm enough to get the office plane outstide and yes, without that 8' ceiling, the radio version of the office plane, with LiPoly cell and carbon prop, will loop in a scruffy polyhedral sort of way!.
Heres some video footage of Graham having some fun at the Nottingham meeting (1.6M)
Well I guess Mark Aeronutz would "turn on is lathe" but here we are, totally non-scale 2-cell office stick planes!!
The defence:
Of cause a office has a low ceiling (395K) and jutting out walls walls (229K) so you need a plane that is tough and maneuverable (685K)
Dave slightly larger and heaver direct drive version also looks promising shown here landing (503K)
The construction is 2mm depron wings, 1mm tail with Aeronutz style actuators. All mounted on a 2mm carbon fibre rod.
Best performance is with a geared KP00 fitted with one of Gordons excellent carbon fibre props, the picture show the standard KP00 folding prop, quite useful in the office!
The latest planes are fitted with single LiPoly cells from Grahams site http://www.indoor.flyer.co.uk Each have a 5V dc-dc
The 14" wingspan now uses the Potensky reciever modified to drive coils with elevator it still comes in at 24grams as opposed to its 12" 18gram infra red little brother.
Heres are some quick snaps, note the dints on the wings, these planes really take a bashing being flow nearly every day in a 20' by 40' by 8' space!
I've still not worked out a reliable short antenna for the Potensky, so for now its just wrapped round the wing.
Oh and by the way the elevator coil is 112R driven directly from the PIC (and still working!) enough power to get vertical.
The next experiment a 'proper' actuator that can be fitted in the fuselage of a scale plane?
This is made of a 3mm strip of card soaked in cyno and wrapped round the magnet. two .5mm pin are the drilled into it and the all thing mounted on a piece of brass shim.
