Did you ever find a fix for this issue, I bought a used caliber 5 with EMS and I am seeing the same thing which you are seeing????

Yes I did find a solution to the problem ther is a couple of ways to go about it I think the best method is the one i used,all you have to do is buy some of thoes little servo spacers, or "plates" that come in a verity of colors, they even make them in carbon fiber,thats what I used. Useuly guys will mount them on top under the screws in place of washers and for added bling,you can also use them as a spacer under the servo and of course you have to use a little longer screws I would give you the link where I bought them but it's been a while but a lot of online stores carry them. I think this is the best and cleanest way to get the job done. if you dont want to do it the right way a friend of mine just removed the section of the wheel that was rubbing against the other servo wheel throught the amount of throw the wheel was rubbing against just a little section along the bottom edge not all the way around good luck I hope this helps! if you run into any other issues and you will ask I will see if I could help no time to spell check sorry good luck JFERA22.
