Hi Ray
As Chris mentioned in a post above "Appearances can be deceptive!" The Bravo is not really HUGE, it was designed to be an approx size as the Alpha yoke.
I'm a Kickstarter backer of the Fulcrum One Throttle and I'm looking forward to it's development.
My only recommendations for it's development. Is for Chris to investigate, the feasibility of incorporating a Trim Wheel. Similar to the old Saitek style of Trim Wheel, this would make it more appealing and would make good use of the Non-contact GMR magnetic sensors for trimming accuracy. I would also recommend looking at the Throttle stick slot gaps to include some form of anti dust bristle strips run either side of the slot, to prevent dust from getting down inside the internal gearing mechanism of the Fulcrum One Throttle.
I'm eventually hoping one day in the future, like next year. To mount both the Fulcrum One Yoke and Throttle to the Yaw VR, Yaw 2 Motion Sim, Smart Chair another Kickstarter project from Yaw VR, that I backed last year.
I envisage mounting the Fulcrum One Yoke and Throttle would be similar to how Yaw VR have done it, in these demo pics of their Yaw 2 Motion Sim, Smart Chair with the Alpha Yoke and Bravo Throttle units which have been clamped to the chair mount desk plate.
So I'm not sure that the comment "a lot of empty space in order to make it visually compatible with the yoke." Is relevant, as it's very subjective to an individual's flight sim situational setup.
