Hello All,

Most of our radios are made using Consumer Grade electronic components which means the max working range is -40C (-40F) to +85C (185F). The actual product operating temperature range would be much less than this for reliability . Just because a component spec sheet says its upper temp limit is 85C does not mean you will be able to realistically use it at that temp - take a resistor for example, it can be rated at 85C but if you look at the derating curve of its allowed power dissipation verses temperature you may see that at 85c is it is rated for Zero power dissipation - Not very useful.

Most of these temperature problems will go away if one ensures there is proper ventilation , moving air around the servo and receiver. The same is true of regulators, you can have as big a heat sink as you want but you have to provide a way to move the heat out, air flow!

For warm/Hot weather flying:

1. Provide a path for moving cooling air around your electronics.

2. Do not place your electronics where they would be in direct sun light.

3. If you are flying a Turbine place thermo insulation between heat source and electronics.

4. If you live in a hot place learn to like light colored aircraft.

5. try to create some kind of sun shade for your air craft while they are sitting on the ground.

6. If you are flying electrics the flow of cooling air is even more important.

7. If anyone tells you these precautions are not important - Don't Listen to Them!

Happy Flying,
Cherokee Jim
