If that's the case Rodney, I guess we should all just pay $28 for GWS single conversion, 4 channel receivers (crystal included). Why spend $70 (plus $10 for the crystal) on a dual conversion?

There is only ONE single conversion receiver that I would trust a plane to at a crowded field, and that one is made by Berg. While it may be POSSIBLE to get similar performance from a single conversion receiver, please don't mislead people into thinking that all single conversion receivers will perform as well as any dual conversion. Doing that is both misleading and dangerous.
