You bet

Trimming soft grasses with your tail rotor won't strip gears, but if you try to make a trench with it, chances are you will strip a gear. Much depends on how much energy is released in the tail strike and how much is absorbed. Variables such as rotor speed, how tight you have your tail blades in the grips, the material the blades are made from, and the pitch angle when they hit are all factors that can be the difference between a survivable tail strike or one that strips out gear teeth. A slightly longer tail fin might help or aftermarket angled landing struts so there is more clearance between your tail rotor and terra firma. Also, belt driven tails are able to withstand tail strikes better than torque tube driven tails - the trade off is efficiency loss.

Replace the pitch slider assembly would be my recommendation. If you're in a bind, you could use medium CA glue on the threads of the pitch ball to glue it into the slider collar which should get you back in the air but hard to know how long the repair will last.

Yes, any slop can certainly cause tail wag.

@@Rchelicopterfun pretty funny cause my last crash was the result of a screw in the tail coming out

There are pros and cons to both. Shafts (normally called torque tubes - TT), are more efficient, don't stretch or wear thus less maintenance is usually required. TTs don't create static potential, are generally easier to fit/replace the boom, and allow for customized boom length modification. Downsides to TTs is they are slightly heavier, cost more, and are easier to strip out the TT drive gears if you have a tail strike. Belts on the other hand are lighter and less expensive. They tend to produce less vibration and are more forgiving to tail strike. Static mitigation practices are something to be aware of with them.

Link slide bushings not long enough. Bad parts 😄

Yes a great idea👌🏻
