This year we are returning to removable rollhoop braces so that we can remove our engine. I remember being at competition the last couple of years and being dumbfounded at how most teams remove the engine(Wollongong comes to mind). Does anyone remove it through the cockpit? I toyed with the idea this year, but it would have required a removable seat belt brace on my frame. I think the easiest way would be to have some sytem that allows it to be dropped in and out of the bottom. Just curious as to see if any of you have some slick sytem.
