Installed the 28T in the GTP that runs on 4s. I jumped from 23T to the 28T. I had no room for the 30T. Estimated speed is about 68MPH with the 47T spur. No bad for 4s. I'm hoping to push close to 80MPH with 4s and 1.5D 1515. Maybe more if someone can make me a smaller spool mount. Pletty was at 159F after a few runs, Acepow was just chilling and RX8 had 3 led on.
