New RC and no more range or loss of link

[Burgerman]

Have you ever suffered from flying too far, out of range (as I do with FPV and a big glider regularly last year) or have suffered from interference, or lost the radio link for whatever reason, you might be interested in my new system.

It uses the usual 2.4hgz signal, and is frequency hopping, encrypted and all the usual. It has the same or a bit better range at between 1.5 and 2.5km claimed or better depending on reciever choosen. These recievers all have 2 antennas for polerisation and multipath null spot protection. And are pretty reliable. These systems are all between 50 and 100mW power output.

So all good then? Well no. not really. As any quadcopter or FPV pilot will tell you, or anyone thats tried using 2.4ghz reliably for ground vehicles or wheelchairs the signal gets blocked by walls, cars, and even shrubbery or trees unless pretty close to you. In the air, a very damp day can reduce your 2km range to half.

Well my NEW radio control system, has the ability to also use 900mhz. And selectable 10, 25, 100, or 500mW. It also has a setting that selects from 10mW up to 1000mW automatically as conditions require it. Automatically based on its own returned RSSI (Recieved Signal Strength Indication) as you fly or drive. And this system has a claimed 10km or greater range. 5x better than the best 2.4ghz. And then some! Theres many people on the internet demonstrating that 40km or 30 miles out is quite easy and reliable in open line of site airbourne use. The other thing is that 900mhz allows the signal to go through walls, and trees and around cars and such. It bounces about, rather than being absorbed by the planet and everything it hits. And is less affected by a damp day as it is not a frequency thats absorbed by water (heavy clouds, high humidity, trees etc.

So thats great. Better still it allows redundency. So my glider now has 2 recievers on board. A 2.4ghz one, and a 900ghz one. Both on totally different parts of the RF spectrum. And both frequency hopping agile on totally seperate bands. And they link together as one, with a short cable. So while flying I have the advantage of a system using both at the same time. And if one gets blocked by something or runs out of range the other takes over. Its almost impossible to be shot down by anything. And you have 40km range! So on with the FPV goggles, and you can fly quite safely 30 miles away from your flying site, above the clouds. In the sunshine. Or miles away at relatively low level and admire the scenery, And not worry.

Damned clever these chinese!

Both these recievers also have 3 axis gyros and accelerometers built in. And they can fly your plane. You program them. So on a transmitter switch, your plane can become directionally, and wing leveling, and pitch stable. So you can forget about flying it and worry about maps, filming, etc. And flip aother switch and it stays at whatever angle you choose. Making it fly like a flight simulator and unaffected by turbulence etc. Makes for smoother FPV video too.

A bomb proof long range radio link and smoother flights.

A 900mhz reciever
Link the 2 and you have the benefits of both simultaniously...
