E010 latency with T8SG

Hello !!

I have for some day a radio control T8SG.
Who serves me has to pilot my small quad:
E010 (Green)
H107D
FQ777-124

For the moment everything works fine.

Except that today I am to buy the second E010 (red) to go up it in fpv with a TX01.
And this E010 ( red) I wants not to work, or works very badly with my T8SG.
When I arrive in him bind, the Quad in a lot of latency. Command put between 0.5sec and 2sec to be taken into the quad.

Have you an idea where from can come the problem? Thank you!

Ok, but my first E010, the green one work perfectly.
I'm always in 30mW for indoor. (same problem in lower power)

this is accuracy of the crystal oscillators in the Tx and Rx too ?

I received my 3rd E010 ( a red one)

Impossible to bind -_-

Possible to have fine tuning for E010 ?

Ok, i buy a E011.
It's the updated version of the E010 ?
