Hello Trevor, thank you for responding so quickly.This information is most helpful, thank you.With reference to the C of G, from reading your earlier posts, bearing in mind I was only attempting a stand off scale project at best, I dispensed with the top rear fuselage planking in favour of an open structure finished in solartex, in an attempt to reduce the weight aft of the CG. Also I have fitted an ASP 80 Which as you Know is quite a heavy engine The result is that with about 6oz of ballast I have achieved the plan CG position.
I am quite pleased with the overall result and I hope you can re
