Edit 2019.0420 Uploades Version 2, which is basically a new construction. V2 is longer, so the COX TeeDee fits with muffler. No more melting because of the hot oil spray and exhaust gases. Also, theres a cavity with two holes on the side for insertig ballast lead. Edit 2019.03.24 It flies: https://www.youtube.com/watch?v=3yRmCxZqdEQ Important: After a few flights, the hot exhaust gases and oil spray melted a hole into the fireall as the exhaust port of my teedee is pointed directly to the firewall. I suggest using an small aluminum or wooden sheet in front of the firewall or flying the cox with muffler. I will modify the Adapter so that a muffler fits. Edit 2019.03.11 Here is the fuel tank that I use 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 of the COX engine beeing lighter than an electric motor with battery, the plane turned out to be slightly tailheavy. I has do add 30g right behind the firewall. AUW is 380g now which is ok - should be no 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, you fit the lower part into the fuselage and glue it in place. Then, push the upper part from behind in it's place and also glue it by using 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 away after printing but it's much more convinient to just cut 30mm away in your slicer. You might have to activate brim to get sufficient bed adhesion.
