I have the Hobbico Superstar 60 with an OS 65LA in it.


The plane flies very well with this combination, it will get up to speed and take off from grass at just over 1/2 throttle.

OS recommend a 12x6 for break in and a 12x7 for general use. I'm still using the 12x6 with good results.

These ARF trainers are very solid with ply fuselages. Although the plane has more than enough power for its intended use, I wouldn't even consider flying this plane on a 40 or 46....

Besides, there's the balance issue.... If you put a small light engine up front, you might end up making up the difference in lead weight....
