SimonClarke June 18, 2019 03:29 AM I don't understand why this and another couple of electric aircraft are mounting the motors at the wingtips. I do understand the aerodynamics around either a tip tank or winglet. I also understand asymmetric thrust. if this aircraft has just taken off and one of the motor computers has a slight glitch there could be enough thrust from one side to completely spin the aircraft. they might have this covered by monitoring the other motor but the last thing you want at take off is zero thrust. they would do far better mounting the props as close inboard as is practically possible. JimRD June 18, 2019 04:27 AM Great looking plane and actually being built. What happens if it has an electrical short and the motors quit? Is there redundancy - like three separate circuits and battery systems? Could it land on one motor. I would feel antsy getting into this one. paul314 June 18, 2019 10:09 AM How many under-10-passenger regional planes are currently in use? Corporate aircraft? riczero-b June 18, 2019 01:54 PM Yes Mr. Clarke, the wing must be an engineering marvel to cope with the motor weight, thrust and aerodynamic flex in such a thin profile. Good luck to them. ilya June 18, 2019 01:55 PM The plane looks cute. Let's revisit it once it actually flies. But looking at the shop it would be a very long stretch get it certified by 2022. vince June 18, 2019 02:05 PM The future of all continental flights is electric. Towerman June 18, 2019 02:21 PM @simonclarke Compared to ICE engines, electric motor systems are reliable beyond comparison, the chances of an electric motor/esc battery failing is very slim compared to an ICE. I do however find it a bit Odd mounting the motor at the tip so i agree with that, in addition, turbulence is more evident or rather amplified at the tips, so the motors will be bouncing about a lot more in turbulent air... it does look nice however. whats the clearance, from prop to ground at the tips. Towerman June 18, 2019 02:23 PM @jimRD Reliability wise you have nothing to fear, electric motors are beyond comparably reliable against ICE engines, the ESC's are solid state, if they are built by a trusted brand and if you look after it (keep them cool and operate them within standards) there is nothing to fear, much safer than current ICE aircraft. Towerman June 18, 2019 02:26 PM @ Vince indeed @ riczero-b Indeed as well, it just doesn't sit right with me having all that weight, bulkiness and power at wingtips. Again it does look nice.. but practically it hurts thinking about what the plane will feel when it flies like that. toyhouse June 18, 2019 07:02 PM The configuration with wingtip motor nacelles does seem odd at first glance, but that's because electric presents opportunities we're not used to seeing before. Perhaps they do it to create the cleanest thrust line possible for charge economy? Nothing behind to create turbulence or drag. Just guessing. As for outboard weight; once airborne, lift takes over some of the stress imposed by outboard weight. The power-pods may also weigh less than typical outboard fuel tanks when full and stress surely wouldn't be comparable to wing mounted jet engines, even out at the tips - the center third engine would balance that out as thrust would now be symmetrical? The size is curious though. Guess they need to cleanup the air going around whatever is inside. No details are given. Interesting design.
