Default Gyro Menu question!

Hi friends...
Got a question on dx7se gyro menus. You can asign the gyro channel to get a GYRO SENSE MENU OR TRAVEL ADJUST MENU. I just want to understand which menu is giving easily the correct gain input. Are they both the same or?

Rudder servos are getting hot(61 degC...ambient temp 41degC!). Am tryng to look for what is causing the heating. I changed the bl9188 to bl251 still the same issue

Thanks for the reply

Ok thats what i have always been using but i just wanted to comfirm the best way and then try to understand further why are the servos getting very hot. What gyro,tail servo are you using on your 700?

Would you mind to share on how you setup your tail for hard 3d?

i use the mks 980 with the gp790 ....
and i order beastx....(flybarless system)
check your limits and the pulse....
i use 760 us for the mks.
most of the servos use 1520.
here one of my flights with all stock

Very nice flyng
The frame rate is correct with my settup but am not sure about the gain issue. Please see my vid below you might pin point the problem from the tail. There is a strange sound on the tail when i make tail stops. I cant understand also how to determine if the stops are reasonable or too much or less. Can these stops cause servos to over heat?

Check your boom brace
and the brings of the rear tube.
I had it too and find that the
Barings was out they place
And so the boom brace was free.

Yap am aware about the brace issue but mines are intact. The problem is when the servo gets hot, the tail start to get loose waging slightly, i mean you start to fight to keep it straight.

Here the outside temperature is 41degC and above in summer. It might be the reason the electronics to get hot and starts to mulfunction.

It would be nice if we get an expert on electronics to veryfy this. I believe these Rc electronics are never tested in reall life of such weathers but they are just rated to certain lab test temp ranges.
