Well what I would do is to stop it from nosing over, Take off the gear and bend the part that sticks into the wing so the gear is bent forward, It sounds like the gear is too close to the CG thus nosing over easy, My US40+ had retracts so I ended up opening up the bays a little and shimming them to lean forward to move the wheels forward when down and it almost never nosed over and I have only flown off grass fields.
