Received my DX4R Pro today and its exactly what I wanted. I had a DX3R Pro but sold it off cuz times were tight and I've regretted it ever since. The DX4R is a nice step up, very adjustable and introducing AVC.

I have a SR300 and a SR3100 with a couple SR3100 clones and a SRS4210 on the way, I just need a couple more and all 9 trucks in my fleet will be controlled with the DX4R. Gonna sell my 2 TQi set ups (RX + TX) and Futaba 3pl + 2 RX to recoupe some of the cost.

Full system on my main Savage XR will be

DX4R - Dynamite LiPo - SRS4210 - Black Edition SC-1267SG & SC-1268SG - Racers Edge Glitch Buster

Should be strong enough to turn the truck and power for AVC to do its thing.

SR2000 is known to have issues when batteries get low. The high resolution puts a high demand for juice and the bigger the RC the bigger the servos and so demand on the batteries from the Servos and RX is increased. Running a smaller RC reduces the overall demand on the batteries so its not pushing the SR2000 too hard it glitches, while some truck glitch a lot with it and it gets worse as batery voltage drops.

They should say its more suited to 1/12 but its new so they might not of forseen issues with people running RC with electronics running the batt on the limits of its abilities. We now know to run it on a small RC or keep it suplied with enough power.
