At one time I did replace the Mag. 46 with a Mag. 52XLS for a while. Yes, the 52 made some crazy HP but I didn't care for the increase in weight at all in that plane. The ASP line from Hobby King is attractive too and same basic engines as the Magnum's.

Andy, if your OS carb is a rear needle version it might just be easier to see how you like the Mag. carb first. The OS 46 carb I used in my Mag. was an older, front needle carb which I like.

Don't baby your new 2-stroke when you break it in. Best to put it on the bench and crank it up to full throttle, slightly rich of course, but not blubbering or 4-cycling, just a rich 2-cycling setting. Let it run and then cool down a few times that way and it'll be ready to go. Do you know why not to run it slobbering rich or baby it?

Thanks,

Ernie Misner
