I'm glad, although theres a few things I should let you know that you'll be need with a T4....being the owner of an $800 one...
That associated motor is cheap and will burn out quick. Even with the stock gearing that thing will be smoking after just about five minutes, literally everyone would smell mine burning the first time I raced it on carpet....Do me a favor and go brushless! The t4 is so versitile that you can race it anywhere on anything basically and you'll go through comm and brushes asap trust me the T4/B4 rise to another level with brushless, better performance, no maintenance(possibly a little bearing lube at the beginning), and even slightly better battery life.
If you are racing offroad, keep those shocks nice and dust/dirt/rock free with some cheap covers before you need a rebuild
The body mount design on the T4 is not exactly flawed but liable to break upon direct impact, due to how they protrude outward away from the tower...I broke both rear ones in one flip over with my stock motor, not about force just the angle of impact can ruin them quick, alum. I broke both body mounts, a front knuckle, and servo all in my driveway lol
Ebay is a great place to look for T4 bodies, surprisingly theres a lot of custom painted bodies on ebay for this car, far more than other cars typically are for sale for the T4. If you race the stocker body, it's almost a big neon sign that says T4 noobie, learned this the hard way and I raced some guy who had the same blue one...not cool
Full metal geared servo for any car basically, JR has metal gears throughout the whole servo I know for a fact.
This car tends to weigh a lot more in the back compared to some others. You want to try to lighten the back, and weigh the front down a little bit more, because when you jump it goes basically vertical, but a simple tap on the reverse sends it back, but a bad nose dive equals broken parts, just happened to me the other day on a big jump on my offroad track.
Those stocker tires are okay, but not for everything obviously. I changed my front tires for offroading because I felt they were losing grip on me, and with a fast motor they don't bite good at all in even slightly loose dirt.
for aluminum, I find ebay is a fast cheap and easy way because this truck is so popular, tower isn't even necessary. for shock covers, www.badhorsie.com
has high quality low priced and fast shipping covers for this truck. You may want to have back up plastics instead atleast for racing such as knuckles or mounts, I lost ten dollars and three heats because I didn't do this lol
Not trying to make you look stupid, you most likely know all this, but this is a general stadium truck thread, just throwing it out there.
