Hey Jason,
Great job on the UB! Looks like you chose all the right equipment to outfit your #1 bird!
The powerjack looks like a neat new (new to me since I hadn't seen one before) concept.
Good call on the fuel system, that motor will take all you can give to it for sure.
Keep an eye on the canopy hoop as you'll tend to remove and install the giant canopy hatch by grabbing the clear plastic, with higher speeds the lone hoop can tend to cause alittle vibration, I used some silicone on mine (prior to its spectacular demise) to secure it to the clear plastic.
Best of luck with it all, I'm sure it will quickly become your favorite.
