Running hot? And loosing cont

[Billyboyx]

My nitro rs4 seems to run hot? I put spit on exhaust and it sizzles off.
Also it seems like engine keeps stalling sometimes it stalls , sometimes it sounds like its about to stall but doesn't.

Also when car goes a bit far away say 5 car lenghts i lose control of it evem tho i have a 2.4ghz control?

You should be spitting on the cooling head, not the exhaust. The exhaust will always be hotter than the head when the engine is up to operating temp. The spit should start to sizzle on the head after a few seconds, if it sizzles immediately it’s too hot, no sizzle too cool.
If loosing signal that soon with a 2.4ghz system it sounds like an antenna problem on the receiver. Make sure the batt’s are fully charged also (both the RX and TX).

What about the stalling

Is it stalling when you put the brakes on?

My guess is if you're using the spit method on the exhaust header,
not the cooling head, you're getting a false "hot" reading and you're too
rich
Pinch test the fuel line leading into the carb while you're at it.
Engine should stall about 3 seconds after the fuel line is pinched shut.
If it dies before the 3-5 seconds then your too lean.
If it dies after the 3-5 seconds then your too rich.

For the HSN, just make sure you have good smoke at WOT, and the motor runs consistent.
If the HSN is too lean, it'll be fast as hell at first, then start to
loose power later in the tank, richen it up if this happens.
