Friends..Colleagues..here i am sharing my new craft..is the SlowSprint...Slow..Sprint..? ..yes..you can fly her at walking speed..or can pump her as a rocket..i am thanking to two of the ever experienced persons, in to Aero modeling, veterans of kerala..Mr Vinod, and Aeronautical Engineer Mr Nikhin..for some guidance and test and routine flights, as i cant walk..actually, i got some extra balsa sheets of 3 and 4 mm, after the completion of a competition..so i decided to go with..
at first she was powered by a 1000 Rpm /Volt motor, but later replaced with even more powerful motor with high rated battery..so

you can see how simple is to make a craft..it spans in to 62 inches, and the wing is made of thermocol..

Nice! What the wing made off?

[Netleyned]

I think in another pseudonym he told us thermocol is another name for expanded polystyrene
If this is the case keep acetone well away

Sir, the wing is made out of thermocol..(EXPANDED POLYSTYRENE)..and laminated with poor quality tissue, with acrylic emulsion, to get a high stiff wing..shape was achieved by sanding with hand, while keeping a template in hand, made of scraped paper...it was reinforced with fishing lines, from inside, and painted with water based exterior wall emulsion..my intention was to fix this wing on a craft with 46 engine, from OS. but it is flying like a dream with a simple 1000 RPM /Volt ECM.very stable and forgiving..the wing structure is far stiffer than balsa, or plywood construction, and absorbing loads of hits without any major breakage..and can repair simply..spans in to 64 inches..thickness 1.7 inches..i laminated two 1 inch sheets ..and total cost of this craft, except electronics is mere 5 dollars..took five, because i used balsa for fuselage..if it was by thermocol, the expense will be in 2 dollars...but she behaves cool all the while, and will land even without motor power...i am happy that at last i made a flyer that in my dream...so have some nice crafts to you all...and HAPPY X MAS to you all....
