Great point Denjones. I'd forgotten about that but totally agree.

Here's the one I used. Notice the raised section that the wheel is on. I placed thin plywood on the tail to strengthen the gear mount since the existing balsa is fairly weak in that location.

This type of tail wheel handles bumps better and won't dislodge your rudder if it catches on something.

I also changed the main gear wheels to 3" ultra-light Dubro's. Since I fly off of somewhat bumpy grass the larger wheels help prevent tipping forward.
