I'd would suggest that you get an OS or Thunder Tiger engine. As a new pilot most likely you will find them extremely user friendly. Any of the engines these 2 companies make in the recommended range would be fine for that plane, so you can compare pricing and decide what you can afford. Both OS and Thunder Tiger engines will last for years. While I have nothing against ST engines, I see novices all the time having great difficulty or needing a lot of assistance getting them to run right, a frustration you don't need just starting out. Get an OS or Thunder Tiger and you'll be up and running easily.
