It would be best to put the 7000 in the arrow. I have that exact setup... The only thing I would add is that youshould take dental floss and tie the switch and battery plugs together. The delay you are talking about is the 3 sec reboot in the receiver and if the battery ever comes loose, even momentarily, it will reboot the receiver letting the plane do as it will for about 3 seconds. I got lucky when this happened to me and it went straight and level... but there was still some pucker factor there. My instructor was not all that happy with me either.[X(] I love the arrow especially with the OS 46 ax in it and the dx7 is phenominal. The arrow will take you so far and then you'll want something more advanced and need the 7000 any way.
