The new EADS cri cri has 4 motors, 4 props with what look like model aircraft props less than 2ft diameter (presumably in this twinned push/pull configuration that is effectively the same as four individual motor/prop combos ?).
Does anyone therefore have any better stats re. THRUST, or is able to help make a comparison based on 4 separate similarly rated brushless motors, driving similarly sized and pitched propellors?
Alternatively if we know the AUW & the cruise speed, can we perhaps work it out from these, or is something more required?
(Im thinking too that the static thrust might be relatively poor say compared to the Fishman Electraflyer using a SINGLE relatively large prop/ motor combo, not geared down by the way, & that in flight and at speed that the model aircraft prop/motor combos 'in MULTIPLES' are actually more efficient??) I suspect they each have different 'characteristics'
