2.4Ghz radio control

Rob, I suggest you read Woodys link, doing this hack will almost certianly get you into trouble if found out, much better to just buy some higher capacity batteries that will more than double their life.

When first turned on, the AR6000 and BR6000 output no pulses until they have seen the transmitter. After which they will output a signal. When failsafing, the preset positions are determined by the position of the sticks when you bound the receiver to the transmitter. The AR6000 of course only failsafes on the throttle channel and other channels will hold their last know position. The BR6000 failsafes on all channels.

The AR6000 is not suitable for robotics unless precausions are taken.

Kanes post seems to be at odds with yours Matt...yours seems to imply that I must set the failsafe position every time I start up.....Kanes says once at binding.

I have the BR6000.
It was bound to the receiver with the sticks in their failsafe positions.

The BEC is a feed from the controller therefore I cant turn on the receiver seperately from the main drive.

Note:- The bot has yet to be driven in competition with the Spektrum setup.

Edit:-
Quote from Spektrum instruction manual...
Fail-safe positions are set during binding, and usually it is only
necessary to bind the receiver to the transmitter once. The only time it is necessary to rebind is if you wish to
use a different transmitter or to change the fail-safe positions

Matt thats the powerup sequence we used for the 40MHz PCM sets for our heavy but for different reasons, the transmitter stores the failsafes in this case, and transmits them a few seconds after it has been turned on and the receiver must be on first to do this, then the main robot power.

On one of our featherweights that uses the DX6 it uses a battery eliminator so we turn the transmitter on first and then plug in the link which powers the robots, both the weapon and speed controllers have thier own failsafes but I didnt know exactly how the DX6 systems work on power up but after the link is put in even moving the sticks does nothing for about 5 seconds so I guess it does not output anything until it sees the transmitter as Kane said, not sure if you have AR6000 receiver but we have the BR6000 and powering it up this way passes the tech check where they fire the weapon soilnoid to here the click, then turn off the transmitter and it clicks again, turning off, not sure what the channel is called but its the left & right movement on the right stick. Same happens on both channels on the left stick with the speed controller.

indeed, for my pcm setup i do the same, receiver first, transmitter second.

Richt stick left-right is AILE if im not mistaken.

This is a nice page over Spektrum in antweights, but this info is pretty much the same for all weightclasses.

Anybody seen these...

I visited that site about a year ago, when they were still selling hot air only.

Good to see there is a new player in the field, more choice for the consumer means better deals for us.

Thanks for the link, mate at work is after a module for his JR tx.

Futaba do the best modules for 2.4ghz that ive seen. They are out in America at the moment, and will be out here soon.
