View Full Version : Ballast Bag Upgrade

08-14-2012, 02:22 PM
Hey everyone,

Last year we replaced the gravity III bags with 750's in the rear. We are thinking of upgrading once again to the 1100's in the rear. Have any of you put 1100's in the rear cabs? Did you have to do any sort of reinforcement/mods or did you just drop them in? We also have 400 in the center (came with Grav III) as well as the integrated bow sack (650 lbs)

Also we would most likely sell the 750s, any recommendations on price?

Just let me know.

Thank you!

Have you tried taking the original g iii bags and placing them under the seats in the cockpit?

Had not thought of that one, I can give that a try! Thanks!

The 1100's take up al of the space and then some... I reinforced mine using this method and it has held up great... no deflection of the starboard at all...
I would recommend it for sure

If your going to run the 1100's, you'll want to reinforce the panels


another way of doing it, this is the way I will be
