Hello, I am a second generation control line flyer, my dad flew control line for years, he always built Top Flight Nobler and Top Flight Combat Streak his favorites, he flew for stunt. I grew up with Sterling Ringmaster and Sterling Mustang and Fox 35 motors I flew for years too. I got out control line flying for a few years and in 1982 I went to the hobby shop one day and asked for a Ringmaster and Mustang kits he said that Sterling had gone out of business. I asked the owner of the hobby shop what had for control line kits. He said he had two kits they were Sig Twister and Sig Banshee I still have those kits today. I use those kits for templates and plans to build my planes I still fly today. I use OS motors now LA40 and LA46. I am thinking about getting in electric planes with my Twister and Banshee. It is hard to get glow fuel down New Brunswick, Canada. Not many any hobby shops here, all mail orders for control line flying. You cannot get glow fuel in the mail here. Thanks.
