I realized that all these engines are made in Taiwan, except the high end ones, which are Japanese or Italian.
In fact, I wonder whether they all come from the same factory, but are slapped with different heatsinks and labels.
The other day, I pulled a Kyosho GX15 engine apart, only to realize...
Dude, brand new engine from Jenny RC is less than a $100 usd.
Rip that engine out, save it for spare parts, and break in a new one.
They run great when properly broken in, I have 5 and they all vary in running temp, but so far I have never had to replace a TRX.
Oh, and for a bit extra, you might...
So the engine cuts out when its hot and will not restart until it cools down? This is a typical sign of a worn engine (piston & sleeve).
If the temps were around 180C or thereabouts on your previous runs, that's what killed it.
If it were me, as the guys said I would check for air leaks around...
Hi Paul
I had the exact same issue when I was starting with nitros and it turned out to be my tuning.
I now have about 5 TRX 3.3 and they ALL RUN HOT but after years of experience I realized that these engines just like to run hot.
I stopped paying attention to temps long time ago, and will now...
