Not for F3B any more...doesn't even have a tow hook!! The recently DS strengthened STRATOS DS is the the 6 molds, with redeisgned control surfaces, and serious carbon throughout (the empty airframe weighs 90 to110 oz) The STRATOS DS is an excellent choice for low speed DS and if you want to light DS and tear up the front side the Stratos 5 or 6 will probably be your plane. GREAT ACRO DS PLANE!!!
