I'm starting trike build #6 officially tomorrow with the arrival of a couple of hundred in steel and a Karman Ghia disc frond end.
Heres what I'm thinking:
I'm looking for 100 mile range. I live in an area of Florida where anything worthwhile is 40 miles away.
I'm looking for 70mph top speed.
Design goal for the trike is 850 pounds with 24 100ah thunderskys
2f1r rear wheel drive.
alltrax 7245 (unpurchased, but fairly certain of the choice.)
D&D ES-15-6 Series Motor (comments on motor / controller choice?)
Heres my first question. Ive included a primitive sketch of the body design, very clean and spartan, the only compound curve on the whole trike is the massive canopy itself. I found a canopy guy who can do a 55" wide x 96" long canopy so the idea is to slope it downward at the nose and use the "bottom" 6 to 8" as the headlight and directional lenses.
I only know enough about aerodynamics to be truly dangerous and realize that (in my mind) the sharpish slope of the rear as seen in the top view looks good, but is it too sharp to adequately fair the air, would I be better off aerodynamically with a wider tail?
Ive settled on the balance issues, know where the batteries will go to get optimum balance irrespective of how heavy / how many riders. Outer dimensions:
108" overall length
55" overall width at front wheels
6" ground clearance
42" overall height (I need to make a new pencil sketch, ive subsequently moved the seat down and divided the batts to one bank ahead of the riders feet and one bank behind the seat.
Anyone here want to do a "mercy drawing" on cad so I can save the forum from these hideous drawings?
