    Quis on F1 Pro Engine Displacement

    morning All, had a Quis on this, was searching in the rules for this class maybe I’m searching in the wrong place, so correct me if I’m wrong, 80cc modified on glow fuel, or 120cc STOCK on gas mix, my Quis is can I run any Brand 120cc or a bit smaller like 116cc? And be ok with your rules? Also is it ok to run Straight/Radius Down pipes . Thank you for your time .

    You can run any brand 120cc stock motor I’m unsure of being able to run a 116cc. As far as the exhaust goes you can run a straight pipe down and if it’s exposed can only be a total length of 8 inches long from the flange to the end of the exhaust tube. I’ve tried looking for more rules on the exhaust can’t find any. On my F1-GT my exhaust is short. It’s straight down and just long enough to clear the bottom of the plane. Hope this helps!
