Wow that was a great deal! That's a good little trainer. Pretty easy to fly. I taught myself how to fly with that plane and it still survives. My son is learning on it now. Tough plane. Easy to repair. I've crashed it a lot. Gotten it stuck in trees. Broke the wings in half. Knocked the firewall out of it. I just glue it all back together and keep flying it.

That looks like an os 40 or 46 la. It's a good engine. Reliable and easy to tune. I have the 40 size on mine. Flys it fine. Have your instructor tune it good for you and once it's running good just leave it alone. I haven't touched my needle valve all year and it runs great.
