Wow! Gary, even though I think the 46 has the best color scheme of the UCD's (sorry Barry but IMHO the giant has the worst of the Do's) I love your pinstriping job! That looks really cool!

Great job!
Yes, I wasn't quite sure about the fit in the cowl with the S 100. I was told by the guy at my LHS that it would, guess he was sort of wrong. However, it doesn't look bad with the valve cover openings, actually, it kinda adds to the beefed up look.
As to your power dilemma Barry, what a quandry! I have seen the "Gigante" and it is a lot bigger, but I had no idea the power requirement would be that much more intense! Were you talking about a YS 140 DZ or the Sport? What's the horsepower of them? They are both 33 oz. engines but the DZ can turn a 16x14 thru 18x10 and the sport only turns a 14x14 thru 16x11. Have you considered aSaito FA-125 or a FA-150? The 125 does 2.2 BHP (.1 HP less than 1/2 HP better than the 100) on a 15x7/17x6. The 150 does 2.5 BHP (.3 less than a full 1 hp stronger) turning a 16x8/18x6! As for weight, the 125 is 25 oz w/muffler (theres a 1/2 lb. better than the YS) and the 150 is 30 (this is w/o muffler, probably the same as the YS with it). Also the 125 is $339 and the 150 is $369. That savings would buy you about 6 gallons of good fuel or a great steak and lobster dinner for two, but who needs to eat right?!

I hope you can get something that would make you as thrilled to fly the giant as you are with the 46! You put all that investment in it to make it fly at least as good as the 46 right? Maybe you could sell me your Saito and help you defray the cost of the larger engine? Unless it's the 125, too much front end for the 46! Just a thought. Sorry I can't remember which size it is.
And Brian, stop thinking about it and get the U-Can-Do 46! Join the club. Worry about the details later and BUY THAT PLANE! You can't go wrong! There's one on Ebay right now for $139 and free shipping!!! What a great deal! Go get it at:
