some question that need answered!
 

are the MX-3 receiver and the LRP AI AUTOMATIC Bullet Reverse esc compatible? if not, what will make them compatible? and one more question. what would be a good servo for my factory team TC4, i am not looking to spend more then 70 dollars.

Andy-The blue airtronics reciever that comes with the MX-3 will accept ANY esc.You may have to shave the plug a lil.Just make sure the colors are in the right spot is all.
Shaving the plug that goes into the reciever with an exacto may be the ONLY thing needed to make it fit.No issue's otherwise.

Good Servo for your TC4 is a # of servo's.If $70.00 is your budget then I would suggest buying used.
It's nice to get a $90.00-120.00 servo for $55.00-65.00

ok so give me a good example of an airtronics servo that would be in that price range. also do you know the size and the number of teeth on a team factory TC4 spur gear? i need to get a pinion for the car and i need to know what size to get!thanks

the FT TC4 comes with a 72 t 48 pitch spur gear

does anyone have a suggestion on a airtronics servo that would work good?

buy a good 2nd hand servo, 70$ -- not enough for a good vnew one

pinion and spur size will dpend on the motor you will use..

i have a 9 turn epic shock motor a 48P 72T spur, so what do i need to get for a pinion?What is the transmition ratio of the factory team TC4?

would this be a good choice for a servo-Airtronics 94738Z Servo-

TC4 transmission ratio is 2.5:1
