Razor and all:

First, let me say that I have only flown TT one time, on my son's Ugly Stick, and it worked very well indeed.

But years ago I bought a second handed Aero-Star with a Magnum XL 46 on it, and that engine pleased me so much that when I built my second twin I got another pair of XL 46s for it.

That pair of XL 46s has been on the same plane for eight years now, and in that time I have never had one go dead in flight. Not once. Except of course, for when I get rambunctious and just stay up too long, and run the tank dry. Tank, singular? Yep. I have Perry pumps on the engines, feeding from a single tank in the fuselage. Two clunks in the tank, with the right one just a hair shorter than the left - the right engine quits a few seconds before the left - safer that way.

The power is great, the reliability is second to none. And I've bought a pair of XLS engines, the OS FX copy.

And I have a real OS 46 FX on my Magic, the XLS engines are, in my opinion, every bit as good, and to repeat, $40 cheaper. That's $80 on the pair, almost enough to buy the third one.

For a final point, whether you like remote needles or having the needle up front, the only real difference between the 46 XL and the XLS 46, the Magnum version comes with the parts to set it up either way.

Bill.
