Posted by GrahamC on 24/12/2011 10:01:20: Oh... and FirstFlight... An idea I've had to think through. Having built the fuselage, I wonder whether it might be lighter and easier to insert formers and plank the top rear of the fuselage. [The turtledeck] rather than use the two laminations of thick balsa as per the plan. TN's way of doing it takes a lot of shaping and adds a lot of solid balsa to the rear of the CofG. You would have to decide for yourself of course, but It seems to me that the sides and bottom of the fuselage are plenty stiff enough to handle the flight loads, and as you are going electric, vibration shouldn't be too much of a problem. Just a thought Graham Hello again! I'm sharing your thoughts about the top-rear planking, but I made it he "quick and dirty” way... I cut two pieces of 10mm balsa, but skipped the formers. Instead I glued another piece of balsa above the formers: My fuselage has warped 2 degrees since I put it together, but I hope I can solve it when I mount the upper and lower planking. (Just noticed that I misspelled angle yesterday, I apologize for that. Better use a spellchecking tool from now on) /Mattias
