I own the Ultimate as well. Most are coming in at 15lbs. Too bad you are not closer. I'd meet up with you and let you have at both of them.
Mine started life on the same 43 that the Cap did and it came in at 16lbs. It flew it but you had no power left over to get yourself out of anything bad. I could do a complete loop if I left it build speed first.
Most everyone is sticking a 50cc engine in that bird and having a blast. Mine has a Brison 3.2 and it's at 15.5lbs and I love it. The Cap and Ultimate are two of my favorite planes. My other is the new WH 33% Edge540 and most likely my next favorite will be the 3 meter Comp-Arf 260 my kids just got me for christmas.
In any case, both planes are big puddy tat's. Here is how I describe the Ultimate.
Big puddy tat on low rates
Big puddy tat with an attitude on high rates
The cool thing is you can switch the rates at anytime on both planes and they will respond instantly. Both are so well setup that if you follow the manual, you will have no problems at all. We have a huge Ultimate thread over here. There is a current concern about one of the wing spars. I have one from the batch that some people are talking about and I have not had any problems with mine. The fix is quite easy and that brings up one more thing. Both the Cap and Ultiamte require very few "fixes" In fact, so far, I have not seen anything on the Cap except for adding some wood at the wing mount saddle to keep it from seperating at the side if you tend to really crank down on the wing bolts.
The Ultimate has a issue on some of them using CA hinges so most everyone is replacing them with pinned hinges. Or than the CA and now 2 planes blowing the top wings off and 3 planes very early on (mine was one of them) having main gear issues, there has been no other problems with it
