I have been having a ton of fun building foam board planes with my 7 year old son. Just got all the electronics so we can actually fly one. I have an AR620 receiver with a DX6e transmitter and am using power pack A from the flite test store. I can't find anything that shows which servo goes to which number. From playing around it looks like the ESC plugs into "1/Data" and the servos for the tail should go to 3 and 4 with nothing on 2. Is this right? The DX6e has two V-tail verisons on it "A" and "B", what is the difference between them and which should i be using? Thanks for any help.
