Yep, you can always count on Brad (Glacier ) to mod the crap out of stuff. He's an excellent guy, and will do anything for you to help anyone out. Keep in mind, he mods the heck out of Parkzone stuff. He has a Stryker that has a top speed of 146 mph, and a brushless J3 Cub with its own camo style paint job.
With retracts you will break more on hard landings, but to some it is worth it. I'm thinking about outfitting a Stryker with some retracts because the thick slab of foam that they call the wing on that thing seems perfect to carve out holes into.
