Hi all

As I fly my glider far and high, I was wondering if the 2.4g is having a shorter range than 72? Not that I can see it 1km away but just wanted to know as I just move to 12FG 2.4 from my 9C.

Theoretically yes.

Practically, no.

They both work beyond visual range.

The 72mhz band permits more transmitted power but to compare the range you need to know the measured signal to noise ratio of the receiver.
Maybe someone that reads this will know and respond to this post.

Apparently range tests have shown the 2.4 system to have better range than systems on 72mhz.That said, the 2.4 system is more line of sight than the 72mhz system i.e range reduces considerably if there is an object obstructing its line of transmission. Output power required is also lower than the 72mhz system.

Hello

Her are some good info on the subject

I am also a glider pilot flying 3-3.4M gliders.

If you look at the World Champinship for F3J world competition. About 10% were flying 2.4. Those guys go out as far as they need to find lift.

I fly in a sailplane competition league. Again, about 10% of the active pilots are flying 2.4.

No range problems. Of course if you install it badly, your mileage will vary.

I have an aerial photography business flying a fixed wing electric Rascal 110 with an Eagle Tree Telemetry system on board, one of my flight files which I have downloaded have shown my plane to be at 1480 feet altitude and downrange 2140 feet from the the radio. I fly with the Futaba 14 MZ radio. The plane also has a 5.8 video downlink system onboard as well as the 900 MHZ Eagle Tree all operating together at the same time. One flight file showed the plane to be at 3150' but that was directly overhead. It was to say the least specked out.

Hope this information helps

aeajr,
how are you guys getting on with 2.4 and moulded gliders? Any problems with high carbon fibre fuselages and range?
Just interested.

Thanks all for the info.

Im in a dilemma too however over at rcgroup/ezone with more glider/hotliner flyers, the feedback was no issues as long as the antennae is outside, I kind of like them look like whisker 90 degree apart in v config.

The biggest issue is heat inside the tight glider fuse. Need to ensure its ventilated.
