I agree with Kirk. I have tried some of the so-called "best" micro receivers and they have trouble in the hostile radio enviroment of combat. What worked perfectly for me at the Fort Worth Texas Nationals in 2006 cannot even be used at my club field in Houston as there is just too much interference. I taped my full size Airtronics receiver to the side of the Ripper fuse and never had a problem with it being hit in a mid air.... might be something to consider doing.[8D]
