The 12 x 14-in deck at right proves a 'bridge too far' when it comes to ergonomics, hence:
(a) 18-in (ply) version an ideal balance between protection, weight and propeller-clearance.
(b) square outline better than rectangular (which required two spars to be foreshortened).
(c) the operator's cut-out is better set back to provide adequate margin for manual controls.
The latter will pitch the C of G rearwards and to compensate I shall ballast with fixed battery-packs plus a swing-seat that will pitch the operator's legs forward and hopefully centre the trim for the cruise.
The picture shows the 18-in ply outline overlaying the 20-in alloy version ~ which must now be modified to suit ~ while the smallest embodiment appears at right minus its rotor-arms.
The dummy propeller parked at the end of one of the (39-in) rotor-arms measures 36-in to suit the one selected for the prototype.
The cut-out is enlarged to 14-in wide and 10-in deep, hopefully providing investors a chance to squeeze in themselves in order to get the 'look and feel'.
I've sat in myriad cockpits during a long life, and frankly this one's up there with them if only for its novelty.
