I would swap receivers with a friend first to see what the problem is and from there it would be much easier to know if the receiver is bad. For the servo do the same thing and swap with another one.

I could tell that when I got closer to the car, the revs became more lively and spontaneous as compared to when I was about 150 feet away with the PCM receiver.

Yeah, I was also thinking some kind of noise is interfering in between the Rx and servos and that the HRS is a little less prone to noise compared to PCM. I'll change my servo extender plug and see if that does anything. Thanks.

Young friend?
or a gullible friend 
Maybe one who wants your precious
All the more now I think the RING is a fake.

Now that you mention, I actually had a problem in the earlier days (when I did not have the RING
) when the antenna connection on the Tx got loose. I thought I had that fixed already by tightening the connection. I remember that at a certain distance, I could not get to control the car anymore. But when that happened, you could see that the steering and throttle servos were acting weird on their own. I'll just check that connection too to make sure.

better yet, put on a new fresh S710 as well

To me traction roll is a very good sign. It would means this particular car has more than enough traction compared to those that did not flip. My first priority would be lowering ride height to avoid traction roll (which is very effective); thus will still give me that tremendous tracktion that other cars dying to have! Next step would have been too easy parts to do.. get rid off those extra traction you do not need. Higher roll center as mentioned by miester D is one way to go, cutting inside front tires 2mm by, I believe, Art C is also the other way to go. Anyway, it is easier task then if I were needing to make more tracktion.

By the way, too much traction doesn't always produce faster lap times you know. it also happens on Formula 1 racing
And yes indeed, lowering your ride height from 5 (front) and 6 (rear) to 4.5 (front) and 5 (rear) will make a HUGE effects. Ready for race in Bandung next week?
From my experience, Bandung chicks are far more better than Jakarta's

Yeah, one who also thinks that I have the PRECIOUS.
