You can replace the gear with anything you want just lay a little lite ply in the fues bottom and go with it. IMO the laser 3D fues is designed great. I have built a couple of them. The tail is the only weakness of this airplane. The counterbalances are a bit large and the wood is a bit weak so it can cause a massive problem. But I never really had a problem with the gear on any of my lasers and I too fly off grass. Its an easy solution, hand launch and catch when in a hover to land.
