JR is compatable with Airtronics. Same frequency shift. Futaba & Hitec are on the other shift.
Frequency Shift is only an issue with radio gear designed for North America (72Mhz). I don't know what frequencies are used in Isreal, but if it's 72Mhz, you have to watch your "shift".
Having said that, many newer radios (computerized) are capable of using either shift, by either flipping a switch, or changing the programming. If you are using a computerized 72Mhz Tx, check your manual. It will probably support both Positive and Negative shift receivers.
