The Cat sounds like fun...a T-34 driver once told me that if a track breaks, it takes 4-4 1/2 hrs to get it back on. American tanks have it much better and a good crew of 4 can get a track repaired on back running in 30-45 minutes...replacing a bad block about 15-20 minutes. (Mine damage is another problem.) Have done it in hot sands, in frozen ice and in 2-3 feet of gooey mud.
A 1;6 scale can't really be that bad, even alone. Even at 350 lbs, you let the sprocket do the work and guide the track in place with a bar in where the pin would go. Get it tight, lock it and couple the tracks links between the sprocket and 1st road wheel. Track jacks are a must in cases of the track being so heavy. I changed and worked on my 1;1 scale T-16A1 for 4-5 yrs and often broke and reconnected the track by myself using a pair of home made track jacks, a long pry bar and a 10 lb hammer. Those tracks were lot heavier. 1;6 can't be that bad if you have the right tools.
