Endpoints are not the problem, you need a stronger servo, like a 645 hitech. It doesn't matter what brand, but you really need a servo with a torque rating over 100oz.in I use a 620mg bluebird servo in my revo G2R and it has 140oz.in with a JR XS3 and so long as you set the endpoints right, it will be ok.
