When we were changing the cone gear on the Trex Helicopters, we found that it's quite difficult to remove the bearing on the cone gear, so we made this tool. You get to remove that bearing and put it on much more easier and accurate, we made different size of this tool for 450 to 700 class. Recommend for all Trex owners.
