I own the T4, and have practiced on my track before it closed and I must say it's design and price FAR surpass the Losi. I can disassemble the entire truck and reassemble it within an hour and I'm slow. It is neutral and can be tuned to one extreme or another and anywhere in between. I love the simplicity, and I love the fact that ALL you need out of the box for the rtr is tires. Get the t4 and check this forum out
