*** Andy Steere's Gee Bee Y Refit Weights Page ***
Below is a table of weights of the old RCS-140 installation and a new table for the ZDZ-40. A little over a pound difference in the engines+accessories. Removing the choke servo and 0.5oz of lead from the nose accounts for the difference in final flying weight, compared to the engine totals. Refer to the original weights page for more weight data.
