On the negative side:
The park is a bad option for flying a glow trainer; an AMA sanctioned club is the best option.
Why? Because you have free experienced help and training not only about piloting, but about safety, proper engine tunning, aerodynamics, field etiquette and comradely.

On the positive side:
Congratulations on your first flight; it seems that you have natural skills.

You need to richen the high needle a little, so the engine is cool and happy at full throttle.

At the end of the day, clean the oil over the wing with Windex and a rag; it is normal.

Best luck!
