Edit 2019.0420 Upload Version 2, a brand new construction, is now available. This version is longer and can fit with the COX TeeDee muffler. The hot oil spray and exhaust gases are no longer causing any problems due to melting. Additionally, there's a cavity on the side with two holes where you can insert ballast lead. Edit 2019.03.24 It flies: https://www.youtube.com/watch?v=3yRmCxZqdEQ Important: After several flights, the hot exhaust gases and oil spray melted a hole in the firewall due to the exhaust port being directly pointed at it. I recommend placing an aluminum or wooden sheet in front of the firewall or using a COX engine with muffler. The adapter will be modified so that a muffler fits. Edit 2019.03.11 Here's the fuel tank used in my Nucking Futs: It fits perfectly into the fuselage: https://coxengines.ca/1oz-fuel-tank-for-cox-engine-round.html Edit 2019.03.03: Because the COX engine is lighter than an electric motor with battery, the plane turned out to be slightly tail-heavy. To fix this, I added 30g right behind the firewall. AUW is now 380g, which should not be a big deal for the COX TeeDee. 2019.03.01: COX TeeDee and Medaillon mounting bracket for the Nucking Futs 400 class pylon racer. This one: https://www.thingiverse.com/thing:3358880 The bracket consists of two parts. First, fit the lower part into the fuselage and glue it in place. Then, push the upper part from behind into its position and also glue it with thin CA-glue. Important: Print the fuselage with exactly 30mm cut away from the nose! You can also cut the firewall and 30mm of the fuselage after printing but it's much more convenient to just cut 30mm away in your slicer.
