I have no experience with the T3 or T4 so i cannot comment but I'm sure it can be made fast if done right. I would personally stay away from it since I don't like belt drive but to each his own.

I've never had a belt driven car and hence was wondering how it would do on speed runs. Any opinions on direct drive transmission? I intend to build a custom speed run car in the upcoming months and am trying to decide the transmission.

Would a direct drive transmission mean that the car would only be 2wd? I think 4wd is almost a must.

Yes, a direct drive would be 2wd like a pan car.

Did you touch ~120mph with the 7700kv motor on 4S. If you don't mind me asking, which ESC do you use?

I also have a direct drive dragster. its faster than the tc4. took me some time driving it but I like it. I've never had a belt drive speed car but i know they work. To me the most important part is good batteries.

TC4basher the leopard is a longer motor(more torque/power) would run cooler can go 5s and gear higher.

I kinda wanna stick to 4s for now. The NEU motor is also longer right? Did you have to cut the chassis?

That was amazing!

What length of Tarmac do you need to achieve such speeds? Is 1000 feet enough?

I'm really not sure but It was a pretty long distance as it was out of range of my Futaba radio by the time it fully stopped. I had to drive my SUV down to pick it up haha.
