Firstflight

Congratulations, Graham! Nice to see that you finished your Spitfire. Where do you have your cg? I agree with Myron that it seems to be a bit tail heavy. My spitfire is now ready for paint, av hopefully I will be ready for maiden in a month or so. Do you think I can have cg as indicated on the plan? /Mattias   Edited By Firstflight on 25/03/2012 18:50:11 Edited By Chris Bott - Moderator on 25/03/2012 22:33:45

Hello again, Graham!I'm made my exhausts from heat-shrink tubing:   You can see some more pictures at http://www.svensktmodellflyg.se/forum1.asp?viewmode=1&msgid=267535   /Mattias

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

Thanks for your thoughts, Graham! I saw the comment from Tony regarding the incidence, and I'm using same angel as on the 72' blueprint. Here is Tony´s comment: http://www.modelflying.co.uk/forums/postings.asp?th=9948 Today I solved the linkage to the elevator as you can see in these pictures:    It was a lot of work to make the built-up tail, and it will probably be heavier than your solution. Here are my weights (excluding the rudder), 59g + 23g:   /Mattias Edited By Firstflight on 27/12/2011 18:17:43

Yes, very nice build! How have you solved the linkage to the elevator? On my spit I`m trying to make a internal linkage (like Denny Fenton did) but my lack of silver soldering skills makes me looking for other solutions.  You can see my building thread here: http://www.svensktmodellflyg.se /Mattias

What about this?   **LINK**     /Mattias Edited By Chris Bott - Moderator on 04/09/2012 17:20:59

Thanks for your inspiring build thread, Graham! I recently bought the plan and cowl to this lovely Spitfire from Tony and I'm planning to build it during the winter. As soon as I have finished my Arrow (designed by John Rutter) the balsa bashing will start. I’ve will be follow your thread with great interest. /Mattias
