It is an issue,although it does widen the tripod base for the rig.The Sylph won't tip,is very stable as reported and at Cd 0.10-11 ( windtunnel at JPL I think ) approaches the lower limit for Cd in ground-effect.------------------------------------------------------------------- I'm running an old air-cooled VW torsion-bar double-tube setup on my Frankensteinian mini-Hypercar project.I'll pay a penalty in Af,but it will also stand up to the monster pot-holes around here,and if I get slammed at the front in a wreck,may save my bacon.-------------------------------------- You've got the right idea with the two-up front,single rear trike,as it provides the greatest potential for drag reduction.-------------------------------------------------- I like your graphics,keep us up-dated.
