I just put together a TC4 I have both the mamba Max 5700 and 7700 motors. I am running the stock Spur gear and switch between a 19 pinion and 21 pinion. I use SMC 5000 2C lipos.
The car is extremely fast with the 5700 motor and close to uncontrollably fast with the 7700.
My 100 foot speed calculation on the 5700 with the 19 tooth gave me est 44 MPH
On the 7700 it was 51 MPH.
I used some agressive ESC settings through. A bit more timing and punch( an aweome feature with the Mamba)
The 21 tooth would make both a bit faster, although a slower start
I wanted a fast car to, but in reality, these speeds are so fast when you are actually driving the car it is hard to comprehend and it takes a LOT of skill. To enjoy this speed you can only go to empty Home Depot// Costo//Walmart lots...anything else and the car is so fast you risk hitting something.
All of this is easily in your budget, Although you have the pricing swapped, the ESC shoud be the more expensive componant. The kit is 180.00 to 200.00 new on ebay for the 7700 and 125-140 for the 5700.. just make sure you get the castle link
