Thanks but it seems a little bit on the high side which is 167 Degrees Fahrenheit This temperature all the wires are melted .I did not have my telemetry temperature on Before but I will switch it on and monitor it next Time.

No way! That is well below the boiling point of water so if your wires melt at that temp they must be made of wax!

Interesting. I was a long-time Futaba user and recall this coming up before when the 6014 receiver was new. When exposed to direct sunlight as in the current CB discussion, it got hot enough to shut down. There was a lengthy discussion here Futaba 6014 receiver heat issue

Some good info in that thread and all the usual sillyness.

As I recall it was a voltage regulator inside the RX that was not spec'd to operate at a high enough temp .. e.g. 60C vs 75C. Other Futaba gear and other mfgs seemed not to be affected. If that 15C delta is what protects a plane, it seems risky to me .. we simply should not put our electronics in direct sunlight inside the plane. Easy enough to fix.

Always surprises me how hot things can get in direct sunlight .. not at all uncommon for iPhones left in the sun on a car seat to shut themselves down when they get too hot .. I've had it happen.

I left the Futaba family only because of their lack of innovation, and their primitive telemetry .. I am a happy Jeti user now so I really appreciate this info. Never ever had a link reliability issue with my Futaba .. nor have I with the Jeti.

So, while it is always good to investigate further and do a little "NTSB" work to understand the issue, my conclusion from this is to add to our list of best practices on installs to not put our electronics, of whatever brand, in direct sunlight.

Default Temp problems

I would advocate either placing the aircraft in the sun to see if you can duplicate the issue , and if so make a note of the telemetry temp of the CB 200. Or, alternatively use a heat gun and gradually raise the temperature on bench to see if you can cause a similar problem.
you could set an alarm on the temp to not fly.



it might not be temperature,

just sayin,

I always keep a couple white towels in the van to throw over the cockpit. I've seen canopies melt even on cool sunny days and some dark parts of my planes get too hot to touch.

Got few phone calls and emails from guys who need more than 15 servos with they Jeti Central Box 210/220
Here is configuration that uses power from Port 9/10 (2x7A) from CB220 for Central Box 100, this way you can have up to 20 high power servos connected to the system. If you connect Telemetry to the CB100 and use CB100 only for nonessential functions you can get away with single power lead and go up to 22 servos.
