I fly mine completely stock, basically no mods. Flys awesome. But when you fly yours, remember to use throttle management especially with a hotter setup. At higher speeds, the tail starts to twist and bend, causing severe trim changes on mine. So be careful and remember it's a foamy and not a pylon racer.
On landings with the stock gear location you have to be careful about nosing over. I think in newer ones there is a sheet of paper with the manual that tells you where to put the LG so that it solves that problem.
