To answer your question:

1. We use Jet-Tronics value and sequencer most of time, since it very easy to set up. Sorry, I don't have too much experience with UP calve.

2. The plane come with wing fences. No extra charge.

3. P-120 will be fine, since this plane have large wing area. The first prototype tested in factory was P-120, no problem at all. Just for your information, if you decide go Titan or P-160, the tail pipe come with combo (in AirPac) is designed up to P-180.

4. Under wing tank available.

5. The plane come out slightly tail heavy. It will just balance with cockpit.
