Marty_d Posted October 11 Share Posted October 11 Look like a lot of fun. Bet farmers who currently use helicopters to muster stock are watching that video and wondering about costs. 1 1 Link to comment Share on other sites More sharing options...

Subject to duration, with that maneuverability, would make a very good mustering tool. Might be a little concerned about its reversing capacity - easily connect with a tree/shrub - situational awareness would be paramount. May be some sort of enhanced proximity sensing equipment, similar to automotive that would, inhibit backing inputs, to prevent contacting "stuff" behind aircraft. If duration an issue - could a petrol powered one be developed - as in petrol powered generator, supplying current to little pod motors?😈 Edited October 11 by skippydiesel 1 1 Link to comment Share on other sites More sharing options...
facthunter Posted October 11 Share Posted October 11 Just one? Then you've got drives and such. Unreliability and weight and how do you vary the speed of each blade? That's how it's controlled.. Is it manoeuvrable or twitchy? Nev Link to comment Share on other sites More sharing options...
onetrack Posted October 11 Share Posted October 11 Weight gain would make the addition of a small genset impractical. Even a camping genset is heavy for its size. No-one has yet been able to produce a very light generator. Link to comment Share on other sites More sharing options...
facthunter Posted October 11 Share Posted October 11 Some PARIS- DAKKAR vehicles work with a non stop generator powering a battery.. It's ALL very hi tech. Nev 1 Link to comment Share on other sites More sharing options...

Not even the turbine powered generators in large aircraft tails??😈 Added bonus, cold probably run on the diesel that almost all land users rely on.

onetrack Posted October 11 Share Posted October 11 Skippy, the lightest weight gas turbine APU I can find is the one on the Bombardier/DHC Dash-8 100 series, and it weighs 115lbs (52kgs). That's the basic twin turbine unit - add in accessories and a fuel supply, and you're probably looking at over 100kgs additional weight. Not exactly a practical proposition, I'd have to say.

Where there is a need there will be a solution - Why limit your search to existing CPU's, check out the RC world even a Wankel or 2/ might do the trick 1 Link to comment Share on other sites More sharing options...

onetrack Posted October 12 Share Posted October 12 A 12 rope-pull engine start, would make for an interesting takeoff experience! 1 Link to comment Share on other sites More sharing options...

I'm pretty sure the machine shown was basically an engineering exercise from someone with way too much time to waste. As onetrack implies, the start procedure must have been an interesting excercise in choreography😁 P.S. Just found pic I took of the description Placard, I have no idea what it says...anyone here that can read French? Edited October 12 by Red Link to comment Share on other sites More sharing options...

spacesailor Posted October 12 Share Posted October 12 There was a ' bicycle ' two motor copter, were the flight control was akin to cycling. Lean left to turn left, ect. I don't know if that gadgetman got it working or if he's still recovering. Australian T V . spacesailor Link to comment Share on other sites More sharing options...
onetrack Posted October 12 Share Posted October 12 Red, the placard is pretty fine print for my aging eyes - but the gist of it is, he's using 62cc Zenoah R/C engines (model G620PU-1) running Walbro carburettors, which are each driving the props through a RADNE centrifugal clutch and a gearbox with a 45mm primary pulley and a 180mm secondary pully, using poly V-belts. The engines use servomotors on the carbies for control. He says the engines produce "6 CV" ("Cheval-vapeur", the French word for HP) each - but that's at odds with Zenoahs website, which says the engine gross HP is 5.46. The French bloke also claims 8000RPM for his Zenoah engines, yet Zenoah say the maximum output is "around 7600RPM". He's really winding those little Zenoahs out! The Frenchman claims the engines produce 25kg of thrust each and therefore a combined total thrust of 300kgs. Not too bad I suppose, if they all keep going at maximum power! He outlines that 6 props runs clockwise and 6 run anti-clockwise, so thus negating any torque issues. He says the frame weighs less than 30kgs and the total mass is less than 100kgs - although above that, he has 105kgs, so some variation in his stats there. The engines are started by flipping the prop or by "an electric device" (type not known). All in all, not too much inherent strength or redundancy there, so I'm inclined to agree with Facthunters, "Pass"! http://www.hobbysupplies.com.au/Zenoah Engines.HTM 1 Link to comment Share on other sites More sharing options...

onetrack Posted October 12 Share Posted October 12 I like this part of the description - "The control is done by means of a radio control on a desk in front of the pilot (on the prototype)" Now, where have we seen this dodgy style of control setup before? 😞 Link to comment Share on other sites More sharing options...
