RS Concept

Hello Everybody.

Me and my friends using the mentioned radio gear (3 identic 7XC radios).

Some use SFHSS some TFHSS or FASST way of modulation.
All of us noted in the last 2 months RANDOM but serious signal lost for seconds.
In most cases it's like that....
I move the steering stick to side and after a second the servo move. Then I move the stick in neutral and after a second or even later the servo moves back. If I do in the opposite side, sometimes the servo even not react.
We did everything, different servos, different receivers etc..
We frankly thing, the RF module of the transmitters has same serious problem...

Anybody noted on Futabas similar issue?

Many thanks.

BR

Peter

have you tried plugging a power cap into a spare slot on the receiver ?
it may be a power hungry receiver

I'm using a T4GRS and had exactly this with one of my models - bizarrely the smallest of the fleet - a micro! Genuine R202GF RX and it would completely brown out the signal when using the steering servo. A home made powercap completely cured it.

I've got the same RX in a few others from a SCT with big servo to a 4WD and 1/8th and never had any issues. Just the micro.
