I've got both a 450 & Dx6i check with Helifreak & you tube if you can not find what you need e-mail me at
[email protected] & I'll see if I can walk you through the set up, but yopu got to be at least a little familier with your transmitter. so you'll know where to look for the settings to plug in. Look over the basic menu's & screens
