this brings back a lot of old memories, first kit i built was a pair of lil satins ,then voodoos, sneakers ,nemasis,the engines were fox combat specials and super tiger G21,35, babby pasifiers for fuel tanks,thes planes would run around 100 mph to 110 mph,then foam wings cam into the picture, engines fox mark 6 combat special with a lot of modifactions could reach speeds of low 130s mph,surgical tubing worked for fuel tanks,and pressure regulators helped to needle the high pressure of the surgical tubing for a fuel tank, the planes were 450sq in wings to 500 sq in wings, if you were a good builder you could keep the weight around 18 to 19 oz with engine, we use to carv or on props, then apc came into the picture. and arrow shafts for booms, the last planes i built were a cross between rich brashes rotation station and allen devues arrow plane, guys like rich brasher and norm mcfadden were ahead of there time, norm was a great engine guy and flew a plane called a cream sicle. i got to fly against the best, like mike wilcox and his dad, the stubblefields howard rush, rich lopez, mike petri, I learned a lot from a couple guys i flew with, bruce coffee and jim womack , the last year i flew control combat i built 106 planes between fast combat and 1/2 combat THANKS FOR THE WALK DOWN MEMORY LANE.
