Micro Sagitta XC


Well i decided to do another micro after i built reds micro wanderer and settled on doing a micro Sagitta XC. i scaled it down to 26% it gives me a 17" long fuse and a 47" wing span with a 3 1/2" root. With the ribs being so small i opted for the cracked-rib method of building this should also help reduce some weight. here is a pic of the wing model hopefully i will have my plans by the weekend so i can actually start building it.

Love this! But what's the cracked rib method?

Thread OP
the cracked rib wing building method in which a balsa stick is cracked at the spar and the ends glued to the leading and trailing edges to form the upper surface of a rib. A turbulator spar is then glued about half way between the leading edge and the spar. The three straight lines approximate a curve. There was a p-30 free flight rubber design called the Hot Box that was built this way. it gets used a lot in rubber free flight and it will save a ton of time and weight over cutting out individual ribs if my solid-works model is correct it should weight about 8 grams less than a full rib build. i will photo it and share this building technique for micro light builds.

Would a micro Sagitta xc just be a Sagitta 600?

Well if a 40 oz sagitta 600 is your idea of micro then ok this would be a sub micro my goal is to be in the 2 to 2.5 oz range

Ah got you now. I saw the "XC" and being old school that means Cross Country to me thus 16 plus feet of wing and to big to fit in my truck.
