Hey Etienne 1,
I've got this kit in 1999 and the buildingtime was round about 2 years, within several stop-and-go's ! Now I've decided to restore my good old Cessna and try to make a glow to electric conversion. BTW I tried to add more scale details, but making the doors functional seems to be very difficult to me, it needs to reinforce the fuselage ! The cut in the bottom of the fuse looks very weak now, you should reinforce that with a plywood frame inside !
Will your plane be glassed ? What kind of trim-sheme will you chose?

greetings
Martin
