Eight carbon‑composite propellers (four tilt‑rotor front, four lift‑only rear) enable vertical takeoff & transition to efficient wing‑borne cruise at ~240 km/h
High power-to-weight prototype
Latest full-scale VX4 prototype features a 20% better power-to-weight ratio than its predecessor, enabling its top cruise speed of ~240 km/h
Proprietary battery + next-gen propulsion
First aircraft to use Vertical’s in-house developed aerospace-grade battery pack and new propeller tech—rapid-charging, high output, with multiple backups
Wingspan 15m from: https://evtol.news/vertical-aerospace-VA-1X
So prop-rotors likely 3.3m scaling from front image.
My own calculations suggest 710kW to 770kW hover power.
With 1000kg of 243Wh/kg cells, Molicel P45B, that gives 2.9C to 3.16C.
Initial calculation ignores resistance, but Molicel P50B has more energy density.
So 19 to 20min of hover time, which will be <15min with adequate reserves.
Cruise at 52m/s estimated at 200kW, so 0.82C, or 1.22hrs.
Allow 5 mins VTOL, gives 0.91hrs level flight. So 170km (106miles) range with no reserves.
All figures are estimates only.
It would be useful to have edit access to posted comments that have been accepted. I often revise numbers once I’ve refined/debugged the method. Edit access also allows revisit of assumptions in response to later comments or data by other users – better discussion…
CAA portal G-INFO shows 3910kg MTOW.

then type “EVTA” in the registration box.
Also shows ballistic recovery parachute fitted.

Thanks for these calcs

I cannot see that functionality unfortunately to enable here. I will check again
