I agree with what you say about the different Ultimates except for the comment that the DP Ultimate is overpriced. The Goldberg ARF Ultimate is around $330 at most shops and the DP Ultimate ARF is $400. I've owned and flown both the kit AND the ARF versions of the CG Ultimate and still own and fly a DP Ultimate. The Goldberg ARF has some great improvements over the kit version of the plane, but the Patrick Ultimate is MORE than worth the $70 difference in price both in the quality and design of the plane. There's just no comparison in the handling qualities of the two aircraft as the Patrick plane is definitely superior. Now this is in no way knocking the CG Ultimate as it is still my second favorite plane after the DP!

I just put a YS 1.40FZ Sport engine in my DP Ultimate and it swings a Pro Zinger 18x6 prop at 8700 rpm which is more than enough power for the plane. It now hovers at 1/4 throttle with ease and can pull out at 1/2 throttle. I previously had a YS 120FZ in the plane which would give it decent vertical, but would require around 1/2 throttle to hover and would only pull out vertically at a bit over 3/4 throttle. In my various CG Ultimates, my favorite engines that I'd tried were the OS 1.08 2-stroke and the YS 120FZ 4-stroke.
