The DX6i, help and upgrades

I just bought the DX6i.  I love the scroll wheel programing, very low power usages and features of this radio.  However, once you buy something it's easy to find things wrong with it.  There is no perfect radio in existence (listen to last show), so here is some basic help/fix/upgrades for the DX6i.

Fix for DX6i and Delta wings: (need 6Ch RX)
Broken trim switches: Fix yourself
Broken trim switches: Upgrade part
Wheel button upgrade: if the stock one breaks
