I build from plans and always {except the plane I want to build again} get two extra copies of the plans, one to cut up, one to build over and I save the original. On kits I know I want more then one of I make up templates on chip board or see temp, chip board is free. Saving money?? I built 8 Up-Roars and the kit sells for about $45.00, by buying wood in bulk from Lone Star Balsa these kits/planes cost almost nothing. When I build a bigger plane like my 80 inch Sukhoi 29 the plane came out at about 1/3 the price of an ARF of the same size. {Guess what plane got the plans destroyed?} The CG Extra and Sukhoi are no longer made, I would really like a set of plans and templates for both of these planes but I never kept the plans or made templates for them. Hind site!! Right now I'm building the Daddy Rabbit from my left over wood pile from other builds, Free Plane!! I may even have enough wood to build the Sun Fli or Drity Birdy. Lone Star is back up and running so down the line I may get the wood to finish up the Giant Hots I started just before there fire? Yes, you can save money, a lot of money but it depends on the plane and the size. One time small planes that are still kitted, not really but you may hurt the plane some day and want to fix that wing, templates tacked to the wall will be a lot of help!!
