Wing construction almost equal between built-up foam construction methods foam wing provides solid airfoil easy finish giving oil can result some built-up wings traditional wood wing probably provides lighter airplane However wing must have plenty strength sustain shutdowns being caught pit man model should weigh approximately 40 ounces have seen some airplanes weigh three pounds Some have successful top speed may suffer takes longer airplanes reach maximum speed will also take longer slow airplanes down reasonable pit speed next wave technology may coming Slow Rat development composite wing construction Steve Wilk Dave Fischer experimenting vacuum-bagging composite wings new models Initial reports concept quite favorable report wing stronger lighter hope see set near future will pass along information becomes available problem plagues Slow Rats slow response controls Most airplanes too nose heavy have marginal elevator sections results stable airplane require lap lead time adequately respond elevator input Moving balance point back and/or increasing elevator area could help condition balance can checked during construction simple method determine correct balance point temporarily attach engine wing fuselage section place elevator assembly various points determine best location may surprised what moving tail section small amount will handling airplane Something else consider during construction adjustable leadouts would great benefit after hard work simple leadout-position change would make so-so airplane good Fuel system Some airplanes suffer marginal fuel
