When you say charge connector...are you planning on charging a lipo in your model?

I want to allow for it to be charged inside the model, but most of the time, I'll take the battery out to charge it.

I know of the general rule not to charge inside the model, but I charge very lightly (only 1A out of the 1C 4.5A normal charge current) and also the compartment where the battery lies is well ventilated so heat should not build. But of course, time will tell. I guess when you charge inside the model, you should assume that everything can catch fire, and place the model in such a way that it would not burn down your house or garage if that happens.


Best regards,
Stein :-)

Test digging gravel and also testing the audio and the smoke generator. The engine sound will be replaced with an excavator sound and both the sound and the smoke will be made to adjust according to the power output of the machine when it's working.

The smoke generator was the surprise that I promised earlier :-)

It works quite well as you can see on the video above. I mounted it so that the output is at the same location as the exhaust on the original CAT 390 F.

I have the 12V, "standard NON ESC" version with red color. I control the variable output with the first channel on the fourth motor controller.
