This will help some but not much, ask me how I know!

The PT19 will get you dialed into going around though. After you get used to that you can use that product engine in may 1/2A CL planes built from kits or plans. 20/30% nitro and 20% oil some or all of it castor oil is the ticket for these engins.

As for flying ability of a plastic plane those Cox PT 19 were among the better fliers.
I agree the PT19 actualy flew. One of the best Cox fliers was the ME109 super stunter IMO
