I bit the bullet and ordered a 55 from Paul. It is an expensive engine, but I have high hopes for it. I saved a few bucks by getting it without a muffler. The 55 uses the same muffler as the 50, and I have a spare one. Not sure which plane it is going on. I have a couple of profiles that are without engines.

I'm tempted to put it on my Burrito since I have another one with a Webra 50 on it. Comparing the two might be interesting, but the 50 is more than enough engine for the Burrito. My beat up EF Edge might be more of a challenge for the 55. It has put on a few extra ounces from being patched together a couple of times.
