RE: help me program my tx
yeah sure. expo is used to soften the response around neutral, without reducign the total throw.
most people swear by it, i can't stand it. i have a bare minimum 20% on high rates on my foamy and 0 on low.
High/Low rates. this is so that you can have low travel for landing/takeoff and high travel for aerobatics/3d. some high end radios support triple rates
hope that helped.
