The epoxy boards would ding and dent to hell and back if you just looked at them. it dissolves like sugar in that stuff as sugar does in water, second: foam cores more and more become an issue when you search around for delamination, not bcs styrole gasses out forever, but ncs the designers are undereducated and don,t calculate the local stresses on the binding areasthat simple! Both Upper and lower wing are removed as well as rear horizontal stabilizer. you would possibly die, This is not so unusual as a group endeavor. I will use Junker style ailerons and ungapped hinged simple flaps. Conyers, GA 30094 USA. 4 years ago Use a high quality brush to get the smoothest finish. Landing gear systems, including gear doors. If it passes static it will be strong enough. XPS is the same polymer but is produced differently, in a sheet-production facility using a different blowing agent. Painting PVA After the mylars have been waxed, a thin layer of PVA is added to help ensure a nice mold release. This is slow for a Cessna, but just about right for the gigantic remote-controlled planes [Peter] has already built. I am helping to fund. I could be wrong, but I dont believe anyone has gotten seriously hurt flying these contraptions. When I install these on the actual model, all the guesswork will be done, and we know they'll work right. Then calculate the area you will need given a length to chord ratio for your flight regime. Dale was a aerodynamics man. To solo in a two-place ultralight, you will need at least a sport pilot certificate. Cell size 1.4 mm to 2.4 mm.
