Got 8 or 10 of the Oranges, none of the Spektrums. But frankly I bought the Spektrum FOR the orange receivers and foamies. You can have a lot of fun cheap with foam. Sometimes it's the building thats the fun part of the hobby. Makin something new, something not seen before or recently. I've got 5 looking at me now. The Twirl, it flies weird but the sight of two rotors spinning is really cool. The bloody wonder just flys fantastic. I don't have my blender all the way sorted out yet but it looks so sweet. My Old Lazy (fogey ripoff) just floats and puts around so nice just like my LzB used too and that F-22, man, something about that long nose as it's scootin by. I always thought the Blue Angels looked like they flew on glass and I know they're great pilots, but its that nose that is far out in front that gives it that solid look in the air. Awesome.
I wouldn't cancel your order, just remember, you could have had 4 receivers OR 2 receivers and another ESC/Motor combo for another airplane.
Then again, you wife may not let you hang airplanes on your bedroom wall. But we have seperate bedrooms so mine doesn't have much say in the matter. I'm 50 and I snore. The least I could do is take my noisy rear somewhere else for her to get a good night sleep. She knows where I am, the walls are vibrating in my direction!
