Ive been flying the supercub in temps down to around 10 below, and have had no problems, I want to take up the nexstar tomorrow, (new steel clevisis and better horns are installed!) Temp to be around 15 above, but supposed to be dead calm and clear, Usually dont get many days like this around here in the middle of january! Is it too cold for the glow engine? will it have trouble staying lit? I use 15% glow fuel with 18% oil. The last flight was at around 32 degrees and the engine ran fine. (just not the clevisis lol) Any and all input is welcome! Thanks all!
