| Hs.{Lord Ernest Hives - Chair} X53 CONDOR IV TYPE TEST In making our next attempt at a type test on the Condor IV, will you please for the duration test use only 20% Benzol mixture, and arrange a separate tank for 50% Benzol for full throttle running. We believe that different percentages of Benzol are bad for gumming, and expect to find that the 20% would give us the benefit. Rg.{Mr Rowledge} | ||
