Mr.RC-Cam 129 Posted February 15, 2009 Report Share Posted February 15, 2009 Here's a video that is making its way around the net that shows a commercially made Quad Rotor model, price tag $30K USD. It seems to fly just as nicely as the DiY Mikrokpter (~$1K USD). Video: Click Me. Quote Link to post Share on other sites
W3FJW-Ron 0 Posted February 16, 2009 Report Share Posted February 16, 2009 (edited) Cute! Wonder if anyone has ever worked on a small gas engine/generator to charge the batteries and power the electrics in these things ? Never seem to hear much about the payloads.

Kilrah 2 Posted February 19, 2009 Report Share Posted February 19, 2009 (edited) Cute! Wonder if anyone has ever worked on a small gas engine/generator to charge the batteries and power the electrics in these things ? I have, but came to the conclusion it was too heavy and would just kill all payload capability. Weight of fuel for a decent flight time warranting the effort is at least as much as a common battery, and there's still the generator unit to add...

W3FJW-Ron 0 Posted February 19, 2009 Report Share Posted February 19, 2009 (edited) A gas engine powering a plane and also driving a generator might be a possibility but would probably approach a 1/4 scale size. Interesting tid bit for thought. Any one ever run across a 2 cycle gas under 26cc engine? Preferably around .40 to .60 in size..

Terry 5 Posted February 19, 2009 Report Share Posted February 19, 2009 Yes a few years back I was looking at a conversion kit that could turn any glow to petrol. Terry Quote Link to post Share on other sites
W3FJW-Ron 0 Posted February 19, 2009 Report Share Posted February 19, 2009 You're jogging my mind Terry. I'm starting to recall a nitro engine with a belt (I think. Could be gear) driven generator offered by one of the bigger hobby stores. Sometime around the time the onboard electric starters for nitros became available. I gotta think more about this just for the heck of it. Quote Link to post Share on other sites
Mr.RC-Cam 129 Posted February 19, 2009 Author Report Share Posted February 19, 2009 Yes a few years back I was looking at a conversion kit that could turn any glow to petrol. And even further back petrol model engines were being converted to glow. Quote Link to post Share on other sites
W3FJW-Ron 0 Posted February 19, 2009 Report Share Posted February 19, 2009 (edited) And Diesel.... Planing heads or machining new heads and making contra pistons... Gawd I'm old...... Edited February 19, 2009 by W3FJW-Ron Quote Link to post Share on other sites
Terry 5 Posted February 20, 2009 Report Share Posted February 20, 2009 Hmm, I'm a bit of a fan of diesel, very good on fuel. I learned to fly on a 1cc diesel 2 channel glider of my own design. It only had a tiny tank but would climb to a speck in the sky before the engine cut and I had about 10 min play before working out my landing. It would of been easier to join a club and get someone to teach me but it was great fun Terry Quote Link to post Share on other sites
