Q-Tee new power plant

So after i have tried 3 different .049 cox engines in this little great flyer, (last one was black widow with throttle sleeve) i just installed a Tee Dee series engine. I put an aluminum crank inlet case with carburetor and everything is pretty tight inside. Unfortunately Greece is under lock down due to this stupid Covid thing so test flight will take some time.
I have also design and print this blue engine mount ''standard cox to Tee Dee adapter ring'' so i can use the standard cox mounting holes without the need to modify firewall. It fits exactly to those Tee Dee engine mounts you can find online.
