intermediate 402 rolling suggestions

[rcaerobob at cox.net]

Another way I've practiced, and help others with this, is to start doing medium rate SLOW rolls...get one slow roll like you want it, then add a second one.  As your recognition of the stick inputs and responses sharpens, you start speeding up the "Slow Roll", until you have two rolls connected, that use the amount of the box you want...This can be very effective at sharpening all the "v-tail" subtleties that a great SLOW roll teaches...
