Donald Brown 1 Posted July 27, 2010 Share Posted July 27, 2010 Hi All I am from the good old RSA and just love flying and more so building things that fly. I have been at it for 2 years now. Started with a 40 size stick, which came to a very untimely end while comming in to land, to slowly, stalled and well the rest is history. I am very interrested in building with depron so the smaller electric planes are what I do. Just recently finished a 44" wing span tiger moth. My hanger consists of 2 SE5a's, the tiger, an EDF Hawk (RTF), a twin boom plane made from scrap foam (flys awsome), a flying wing. and another own desine I call a PD Special, it is what I did most of my learning with. It can do everything you want while learning and just floats in to come and land (has a full profile wing and fuse) Quote Link to comment Share on other sites More sharing options...

Donald Brown 1 Posted July 27, 2010 Author Share Posted July 27, 2010 Thanks David BTW where can I find foamy plans featured in RCM&E like the Bristol F2B that I have? Quote Link to comment Share on other sites More sharing options...

David Ashby - Moderator Posted July 27, 2010 Share Posted July 27, 2010 Don The plans service is here. Not sure there's a foamy category but you could try putting the designer 'Cyril Carr' into the search box? Quote Link to comment Share on other sites More sharing options...

Donald Brown 1 Posted July 27, 2010 Author Share Posted July 27, 2010 Thanks Robin and Dusty I am from Bloemfontein and fly with Bloemfontein Model Aircraft Club. Also love war birds and plan soon to build a foam version of the Tony Spitfire which was a free plan in Aeromodler earlier this year Quote Link to comment Share on other sites More sharing options...
Simon Chaddock Posted July 27, 2010 Share Posted July 27, 2010 DonaldLike you I found Depron a fascinating material that you really can "build" with and is well suited to "leccy" flight. It is of course much lighter than balsa but Its actual strength to weight ratio is similar although a bit more flexible, which can be good thing!I found that a moncoque type structure works well as it keeps the stresses low and spread throughout the material.My initial "built up" all Depron wing using 4mm sheet. The completed wing and aileron. The only balsa in the structure is the leading edge.Where higher stresses are unavoidable I found simple balsa works well as it can be glued very effectively to the Depron so the loads fully transferred.The composite balsa/depron/balsa spar used in the thin (9% t/c ratio) version wing.Although everything is glued I found that ordinary Sellotape significantly reinforces any joint. The leading edge on this wing is 6mm Depron sanded to profile and covered with Sellotape, in this case really for strength but to provide a smooth surface.The completed 40" span wing weighs just over 2oz and that includes the two aileron servos yet is easily supports a 14oz plane pulling the tightest loop! I hope this helps. Depron rules ok! Quote Link to comment Share on other sites More sharing options...
Kappie Posted July 27, 2010 Share Posted July 27, 2010 Hi Donald, Have a look at this website: RCFOAM.COM They have free plans for foamies and some links to additional plans websites. Cheers Quote Link to comment Share on other sites More sharing options...
