Like a long wheelbase recumbent bike the leg position lends itself better to pushing backwards than forward. With the foot throttle and body work you are essentially in a two wheel car. Ideally there needs to be some speed sensitive landing gear with small wheels.
Time how long does it takes your compressor to fill the reserve tank to working pressure (90 psi is common). Calculate the volume of the reserve tank and the volume of the cylinder stroke. This will tell how often the cylinders can be used. With you in the seat, measure the ground clearance and determine how much lean is comfortable at a stop or getting out. The vertical center of mass is just above your belt line when in the seated position. Measure that height and it will the same as the distance from the vehicle center line to the contact point at a 45 degree angle.
