I have a small update on the SMD SRX2 (And I'd presume others using this case as I highly doubt they are different inside)
I've had cases of the car loosing connection to the transmitter (Exzes X) and running away at two tracks. Both of these have metal link fencing in close proximity to the track (i.e 2 ish car withs from the edge)
Unfortunaly I do not own a genuine Sanwa internal antena reciver to compare to but I think it might be a limit of the internal antena recivers in general rather than these specific ones and the cars have worked fine with a pair of Sanwa recivers with wire antenas

How is your receiver mounted?

Post a pic.

It's been positioned between the servo and ESC with the high side of the reciver facing the outside of the car. I've always had my recivers in more or less the same spot in a touring car and the SRX2 has shown no issues positoned here indoors
(Will update with Image once I'm back home. For now this is close to how mine is

Sanwa compatible receiver can also be found on Amazon.

Please, help needed !
I cannot bind my M17 transmitter with my RX491 receiver.
I'm following the procedure : led of the receiver is rapidly flashing when it is connected with the transmitter on bind mode selection, but even after 5 minutes, the light of the receiver never get glows and bind is not done.
I tried several time but still the same..

Receiver connection :
CH1 : steering
CH2 : ESC
SSL : bing plug

Transmitter selection :
RF Mode : FH5
Response mode : SHR (with a SRT BH9027 servo)

Is there something I have missed or doing wrong ?

Thank you for your help.

Please ask in the M17 Thread please: https://www.rctech.net/forum/radio-e...tl-pistol.html

This is the thread for non Sanwa branded (Sanwa Compatible) receivers.

Thank you
