sweet so mugen springs the main problem ive heard with the stock servos is they are slower then molasses on a cold day lol but Im no pro so they may work for me not to mention I can always set the radio to have more of a direct feel by adjusting my subtrim up till its right before its on throttle I love having my radio I understand completely why people suggest having an upgraded radio I use a 3pmFS I just wish futaba digital servos werent so expensive so I can use high res mode
