My Twister panels are about 14.5 oz RTF, and that is with a 9351 which is about 2.1 oz. Foam/balsa, covered with Ultracote.

The fuse after painting (still no firewall installed but everything else in place) was 34.2 oz.

With 5300's, the Pletty (which is a bit lighter than the Hacker) and the Schulze 32.80 which is a heavy beast (4 oz)....I am educated guessing...10.5-10.7....so I think you will be alright even with those panels.
