View Full Version : Backyard bashing overheating
01-17-2001, 01:16 PM
my rustler does the same thing, as does my t-maxx. it is the extra drag on the truck causing it. what interest me are those cooling fans ou can buy...i am considering rigging one up on the maxx so it doesn't have to be run as rich.

Your T-Maxx also runs too hot in the backyard?? I am planning on getting a T-Maxx soon and assumed the really low gearing on it would prevent the overheating .... tell me more ....

has the weather changed at all? if it's realy hot or realy cold out your engin will do strang things like run realy hot or have poor eceleration.

Nope ... was the same day .... about 15 minutes apart.

How do you know it's running too hot? I think I may have the same problem...when I run it seems fine, but when I'm done sometimes i notice smoke coming out the back. Also, my exhaust (stock) is burning holes in the body!
I cut out the windshield and cut a hole in the back. That helps with the smoke, but the exhaust is still burning the body...

Good point ... and w/o a temperature guage tough to quantify. I was comparing it to how hot it seemed after running 8 tanks of fuel w/o much cooling down, to running one tank in the backyard. In the backyard it was hot, smoked, discolored the lexan near the exhaust, heated up the bottom plate of the truck, etc. I do have cooling holes. And we did run it harder in the backyard http://www.traxxas.com/ubb/smile.gif I just hate to ruin the engine by stressing it too much.

Well its because its taking too much dragand its revving higher constantly and thats making it getting hotter much faster than such as on the pavement
Dude lay off the 60 percent!

Nitro Rustler ... properly tuned. Runs GREAT on pavement, mixture properly set (on the rich side), cooling holes in body (front, side, back) ...
Normally the engine appears to run at a normal temperature. In the backyard (grass, weeds (cut low), dirt, etc.) the Rustler runs VERY hot ... tried making the mixture a bit richer, no help. The truck runs great back there ... wheelies, etc., but I'm suprised how HOT it gets .... and on only one tank of gas! I dont have a temperature guage to measure the temp, but it is higher than it should be.
I would expect this truck to do some good backyard bashing w/o overheating. I could try to change the gearing, but suprised I'd have to. Comments?

use a fuel with higher oil content and if it still overheats then richen the low end
you can't say can't

Well Traxxas does clearly state that their engines have a high heat characteristic. I do notice smoking sometimes from the engine...I know i'm running hard and I'm also using 20%. And the side stock exhaust burned a hole through the paint job on the lexan body. I did cut out the entire winshield and the upsidown triangular rear windshield. That seemed to help a little...But I dont think i'm running it that lean to worry about ruining the engine.
