Yes it will.
The DX3R and DX3R Pro will work with both the DSM surface receivers like the SR3500 and the DSM2 ones like the SR3100 and SR3520.

That's what I thought but Im having trouble binding them. My sr3100 is pretty quick to bind but this sr3500 just doesn't want to. Its so simple to bind can I do something wrong!!!

Hmm. Strange.
I've bound other DSM1 receivers to my DX3R without any issues but there are a couple of things to possibly be aware of.

1) The DSM1 receivers like the Sr3500 will take longer to bind than the DSM2 ones - DSM2 is faster - so I would expect it to take a bit longer - maybe even upto 1.5s

2) I've experienced occasions when the Tx appears to be too close to the Rx and moving further away from the Rx results in a successful bind. Cant really explain why other than perhaps the 'shape' of the 2.4GHz signal results in a blind spot when very close to the model

3) Lastly, try binding it whilst the Rx is being powered directly from a separate receiver pack with the Esc unplugged. This can make a difference during an initial bind process when the Rx is new - especially if the ESC is also new and not calibrated to the Tx. It seems that some cases, power can be interrupted to the Rx if it doesn't receive a known Tx signal within a time-frame. This appears to be ESC specific - can't explain why but it could be that if the bind is taking too long, that the Rx power feed is being shut off - either by the Rx itself going into a fail-safe condition or by the Esc having not been sent a recognizable position signal from the Rx. Difficult to explain but something that I did experience with the Castle ESC and something that I resolved by binding the Rx whilst powering it with a separate rx pack with the Esc unplugged.

I've never had an SR3500 but the DSM signal is no different to the other DSM1 receivers like the SR300 so I wouldn't expect an issue.

Failing that - can you bind the Rx with any other Spektrum DSM Tx? Is it a brand new Rx or a known one? If you're still stuck after trying the above, try contacting Horizon Hobby UK and talking to one of the guys in service there. They really are top notch
