Sean,
All the stupid questions...was it a good RX before you put in in the bar? With all the rough handling of installation (plugs in/plugs out..drop it a couple of times when it falls out of the fuse etc it may be broken) Just ask me how I know these things. Another thing that I didnt know until recently is the dual conversion rx's require a special crystal, if you've changed crystals check that. I always range check with the TX antenna installed but down with the RX antenna and the TX antenna pointed at each other (the worst possible case). After I get a good check there I do a antenna up and walk as far away as it will work.(Thats why Seguin is a good place to test fly..you can walk all the way to Gonzales for your range check. Then I start all over again with the motor running and compare. My idea is if I cant see my airplane any more it is a good check. For this one I place the running motor between me and the RX antenna to get the worst case, again with the RX antenna pointed at the TX. If you dont get a good check with the ecu/pump/motor off I would call it your Rx, especially with the antenna out of the airplane. Another thing is set the plane on a plastic box,table etc to get it away from the ground for the motor off checks. I suspect a broken/loose crystal in the RX. For my Hawk I'm trying a Revolution antenna mounted inside the fuse, no range check yet though, gotta get my motor back and installed first.
