RE: Inexpensive 2.4Ghz system compatibility
You may want to check the AMA regs on radios. If it is not type certified by the FCC it can't be used under the AMA regs. If you want to fly outside of the AMA then take your chances with the quility of the radio and your plane. Without the testing by the FCC you have no idea if the radio meets the standard or the safety of the system. The only things these cheap radios are good for are foamies. Dennis
