Maybe Typhon is different, but it might be worth it to check the servo saver adjustment. The rep.from the warranty dept. told me some Typhons had shipped with it way to tight, as was mine. My stock servo died after about 10 relaxed runs, not any thrashing. After loosening it my servo has lasted many months of near daily use. While waiting for the replacement, I bought a Savox SW-0230MG and it is fine for my Typhon...maybe not enough nut for the Granite? HTH
