I am flying a Fun-Key 600 size MD 500. The fuse did not come with any side windows. I am running a 12s electric setup. Any idea if I could install side windows without overheating the electronics?

Thanks

What headspeed, kV, gearing, etc.?

E820, Raptor G4N, X50F/E, E620, Forza 450, and some planks.

Although not as large as your Ranger, I have just done the same thing with my Canadian Forces training version (550 size). It had completely open side windows and now they are closed in. I have flown it in 90 degree+ temps and no issues so far. It is a 6s system with everything in the exact same spot as it was when it was a pod and boom helicopter. If you have a logging ESC, have a look at it while running now and then close the windows in and fly it a couple of times to get an average. I did make the sliding windows work in the front doors but didn't do it with the rear doors. If I had ever hit a high temp (fingers do work good for getting an idea of how hot it is), I would have opened up the rear sliders. Have fun with it.

PS: You can always use screen in place of the plastic if you do hit high temperatures. It's amazing how well screen simulates the window when you see it in flight.

You might look for the 118t spur and then increase your motor rpm to give you the same head speed (if you find it not too fast) and that will help reduce the heat made by the ESC. Mind you, it should not be pushed too much anyway, as it is a fairly light helicopter, higher than usual head speed, and well within the range that the ESC is comfortable working at. Take care.
