Ibu2 i had to change two sitches on the settings. Like i said i also set a dual rate on my radio to null down the throttle for battle engagement.
i will warn you a 12v battery takes up a ton of room. I built it from 5000mah C cells, normal rc car packs are sub C cells so its huge. If i were to start over and do it again I would remove the battery box, place one stick of 5 on each side with the ibu in the center, srap down the batteries and use the battery door to open for chargigng access. That would aolve a bunch of issues i encountered.
