I also have the V2 of the Tundra. I bought a newish DX6e so I could set up the flaps. (definitely not required). Nothing but problems with the flaps. Could not get them to deploy evenly. Bought some $32 metal-geared servos for the flaps and still have problems. Took it to Alliance Rc, in Mesa, AZ, and Steve spent quite some time helping figure out the flap thing. As it turns out, the flaps on the left wing tend to have sticky hinges. I tried loosening the hinge screws and lubricating them and still sticky movement. So, I'm about to give up on the flaps. Didn't contact Hobby King to try to get a new set of hinges. So, probably I'll glue on some popcicle sticks on the wing bottom to hold the flaps flush with the wings. Maybe then I can get the plane to trim up and fly straight & level. Also, I bought the AR637T receiver to get the AS3X to help stability. Well, I must first download upgrades from Spektrum to get the DX6e to work with that stuff. So, I put in the required micro chip into the computer and downloaded 2 upgrades. However.....they are .saw programs and my computer will not open them. Seems everyone is having trouble opening the .saw stuff. So....short answer to long problem.....forget the flaps and AS3X and fly it like a 4 channel plane. End of story.
