I will try to put it in a different hole, I tried putting it in the last hole but I could not get the gear on.

Thats because the hole in the firewall is in the wrong place. Yes I am aware that it may be where the factory placed it but regardless its in the wrong place. It needs to be directly lined up with the end of the arm and that is usually clear over to the side or close to it. The pushrod needs to all the way in the last hole out at the steering arm and at the servo always start with the pushrod at the closest hole in.

If your firewall outlet is aligned with the end of the steering arm and hole is drilled oversized with any rod housing if used floating free you will be rewarded with an almost friction free steering and that will make a big differance.

If a housing is used it can be glued at the the first cabin bulkhead to prevent it from sliding fore and aft, this when the housing floats free in the firewall.

The reason for this is the fire wall is always to close to the steering arm and as the pushrod moves it swings sideways and jams aginst the bulkhead actually trying to bend the pushrod.

The Fults is a wonderful gear for a heavy airplane but very much overkill here but worse it will not cure your problems which apparently are the flopovers and propstrikes. Fixing you linkage will cure the problem however.

Excessive nosewheel throws and or binding pushrods are a recipe for poor ground handing i.e. flopovers.
