I've been racing the TA05MS in Mod for the last few months. In the most recent leg of the Drivers champ at my club I finished 1st and I also came 3rd in the Winter Champs - this was against a field of mostly late model or current XRays (in fact there is only 1 other Tamiya chassis being used).
The kit I am running includes..
Spektrum SR3000 Rx + DX3.0 Tx
Futaba 9551 servo
LRP Sphere Comp TC Spec ESC
LRP Vector x11 3.5T BL (with ceramic bearings)
Titanium screws throughout
Titanium turnbuckles throught
Square aluminium front uprights (5 degree caster) and C-hubs (note: this may mean lower arms break easier!)
5 cell Intellect 4600 packs
All bearings replaced with Acer Racing ceramic nitride bearings (and some JAAD racing ones for inside the diffs etc).
My car weighs in around 1480gms and is balanced perfectly left to right without using any additional weights. Front to rear balance is about 55% weight on the rear and 45% weight on the front.
The main points of wear would be the aluminium outdrives on the diffs (which I use in both the front and rear). The plastic swing shaft protectors wear fairly quickly and then the outdrives start to have a groove worn in them.
The holes in the steel wheel axles where the universal cross joint pins go through wear larger over a period of time giving slop in the wheels. Combined with the diff outdrive wear this makes for a fairly sloppy wheel unless these are replaced (I havent replaced either of these yet, but suspect that the outdrives/wheel axles should be replaced maybe every 3-6mths depending on your budget and carefactor).
Diffs last about 2-4wks without needing a rebuild and I'd be doing this once a month and replacing the steel diff balls (and either replacing the diff plates or flipping them) if you use them to keep the diff smooth. I am now using ceramic diff balls from JAAD racing and find that the length of time between diff rebuilds is about twice that when using the standard diff balls.
Centre pulleys wear fair quickly with the wrong tension on the belts, which ultimately leads to belts slipping and stripping teeth on the belts (same experience both front and rear belts for me).
Universals need playing with a fair bit too as the grub screws in the cross joints come loose fairly easily. Use a combination of threadlock on the grub screws and notch the pin half way down where the grub screw bites in and you'll stop having issues with the pin coming loose and locking the swingshafts (which in my experience can lead to stripping centre pulleys and belts, but is only really of an issue when using the spool as there is no diff action so this forces the belts to slip on the pulleys).
More power = more speed = more wear and more serious damage during crashes etc. Get yourself some replacement front and rear damper stays and the D parts sets (for the front and rear lower arms).
I'm sure there's more that I could babble but thats a good start
