Range is only the result of the wanted signal to noise ratio. Local noise emitters are the most common way to ruin good receiver’s capabilities to pick up weak signals at long range. The system got a transmitter to receiver calculated line of sight range of over 100km. We know at least one customer who actually performed a full flight over 100km out and back. To be able to get the full possible range this system can deliver, you need to be very sure nothing on your plane emit noise in the used frequency band, if it does it will affect the range. This means also it is very easy to detect using range checks.
Can be done just like any conventional RC systems and please follow the following steps:
Landscape variations and noise pollution in the flight area is known to shorten the range of any wireless link. Use at least 1/10 of the distance as height. For example at 3 km/1.8mile, distance stays 300 meters/984 feet up, to get full range.
Tx700Pro will provide you with a signal to 100km/62 miles range depending on power selection and on which receiver is used.
Tx700Lite will provide you with a signal to 25 km/15.5 miles range depending on which receiver is used.
