http://www.flixxy.com/personal-helicopter.htm > http://www.flixxy.com/personal-helicopter.htm Neat. Didn't the US Army play with that concept back in the 50's? Contra-rotating blades and attached to teh back of the trooper? p.s. I seem to recall seeing one at WPAFB and another at the air & space museum in 76' -- Keith > http://www.flixxy.com/personal-helicopter.htm But what a subject for a model!  SignatureTim Wescott Wescott Design Services http://www.wescottdesign.com Do you need to implement control loops in software? "Applied Control Theory for Embedded Systems" gives you just what it says.

A skill that I lack, sadly. 8^) I've similar one in mind I'd love to do. Always wanted to do a large scale Kaman Husky with turbine power. It's daunting enough I wont do anything but dream. -- Keith >> >http://www.flixxy.com/personal-helicopter.htm >> [quoted text clipped - 4 lines] > a large scale Kaman Husky with turbine power.

The rotor separation would be way too big, and there would be that big not-to- scale flybar, but it'd be _close_ SignatureTim Wescott Control systems and communications consulting http://www.wescottdesign.com Need to learn how to apply control theory in your embedded system?

The details might lack but I'd like it so you could stand back hold up an old aircraft ID flashcard up and it would be RIGHT...as in the silouettes would overlap perfectly. I'll leave stuff like perfectly scale interiors and rivet spacing to the obssesive compulsives. 8^) I still remember watching them fly on a regular basis at McConnel AFB. -- Keith > You could maybe do a close stand-off scale with one of the twin-rotor > almost-toy ARF mini helicopters that are showing up these days.

I meant this. http://www.aircraftresourcecenter.com/AWA1/201-300/walk252_HH34_Husky/walk252.htm http://en.wikipedia.org/wiki/HH-43_Huskie A nice turbine powered version. 8^) But not likely to happen...I am not skilled enough. -- Keith |
