Cons:The ball link suspension sucks ass!! I have the misfortune of owning an Inferno TR-15 and once every 3-5 minutes or so I have to snap a lower control arm back onto the chassis. Hopup parts are non existant, the engine is available ONLY with the car (gs-15r) it has been discontinued. There is ABSOLUTELY NO aftermarket support. Crashes will always kill bulkheads, ruin fuel tanks and bend your chassis (at least that always happens to me that way) Some of my wrecks were at relatively low speeds (10-15 mph) and I still broke tanks.
Pros: Tuning on MY car is a breeze. It runs no matter where I take it to, cold, hot, high alt. it doesn't care. Pull the cord and it starts and runs. This was my first car, and I didnt know jack about tuning, aside from where the previous owner said to turn the dial. I left it there and away I went. For a little car with a pathetic looking motor (with even more pathetic internals) ths car scoots on dirt
In closing, if I had to do it over again, I would NOT buy another TR-15. Buy a truck that has parts IN-stock at the local hobby shop. I hate waiting a week for my order to arrive from tower hobbies.
