Any tips on buying a RC car?

You have batts for the controller, and on the truck but stock the truck probably has a double a pack. But there should be a "Easy Start" controller thingy that plugs into the back and it turns the motor over.

Yehh so is that what uses the 7.2 batt packk.....i still havent read

i think it is a valid point... will there be catastrophic failure? prob not, but there could be a premature wear.

if you heat up the head to get the sleeve to expand it is far less wear than a cold start...they dont even recomend a heat gun..

7.2v battery pack goes inside it after its charged of course.





then it plugs in like this and hit the button

still need to charge up the glow plug though . when you are ready to start it it locks in the center top of the engine. basically it just heats up the plug

i would get a temp! gun



as long as the engine is running at 185-240 degrees it should be happy run it colder the piston and sleeve will wear run it too hot it can fail.

No....should i?
Guy says follow the book....says like 1/4 throttle for first tank, 1/2 next....etc

Like 5 tanks it says.....think i should buy more glow plugs for that?

for warranties sake i would follow the book. i just read my manual which has a disclaimer in it. i had my revo though before my other nitro buggies and broke it in by the book. as you get more into it and if you run with guys at the local shop they can show you a few tricks or two about tuning. gotta be carefull though my old man about set us on fire with the heat gun before yappin at a guy at the track about football and pointing the heat gun at my fuel bottle LOL so i would just get used to stuff first

Yes, a temp gun is absolutely vital to tuning and keeping it tuned.

Vital!!!! Get one!!! Now!!!!!

There is a lot of misinformation here... The EZ-Start will heat the glow plug, the Revo has a rechargeable pack for the truck (for servos), temp gun is good the prevent overheating the engine but you should tune for performance (acquired with time).

OP,

You need to read the directions a couple times and watch the tuning DVD a couple of times as well. Maybe you can have someone with experience help you during break-in.

1) Exactly

2) I think thats the whole point of "tuning" any motor, your not "tuning" to decrease performance? The problem with tuning is people tend to tune too lean resulting in better performance but then the motor runs far too hot.

With a heat gun you can monitor the temperature of the engine while tuning to get the best performance possible out of it. Otherwise you have no idea what temperature your running the motor at and can severely damage it if you overheat it.

These tiny little motors are sooo touchy. A small change in temperature, or even elevation can drastically affect the tune....

You can get a infrared temp gun for $32.

I killed my first motor tuning for performance without a temp gun. . .

Do what the manual says with the first 4 tanks of gas, and you will be fine. Run the motor around 260-280 degrees and it will last a long time. My last t-maxx was on the 4th gallon of fuel and still running strong.
