I have been using the Velocity build manual as reference for a Locost build & set the spacer washers as suggested which gives 2-3 deg neg, I measured mine and its about right.

Can anyone with a SVA'd Locost or Velocity and on the road OK that setting for the castor angle, does it self centre OK

2-3 degrees of caster sounds a bit low i think the Locost design aims for 5 degrees , which still seems a bit low on mine ,could do with more self centering .........

ive got loads on mine and it only just shows signs of self-centering, ive had to modify the bottom bones on mine to give me more. phew

i think the book chassis is supposed to have 5.5, but depends on wishone design as Billy says. Lower pressure in the tyres helps at SVA time as does a bit of toe out..
