Hey John did you get to run your E4 back to back against your Photon? If so how do they compare in handling for you?
I haven't gotten my Photon yet, still waiting ...
But I have driven the TRF416WE and the Dave Erlich E4 and I have to say the E4 was better balanced and more predictable. It has a faster polar moment and really likes to rotate. With the double steering setup and the one way it drives very nice. The Tamiya on the other hand I think needs a better servo saver and is a bit loose when pushed too hard .
