2.4Ghz radio control

[leorcc]

you can buy them right now if you want from http://www.robbe.comwww.robbe.com but ive already contacted them and their system only does throttle cut, not our kind of failsaving needed on the receiver.

Ive sent an inquiry mail about the receiver failsafe settings of the extremelink at http://www.xtremepowersystems.net/http://www.xtremepowersystems.net/

quote:

I have seen the receivers on the website but I need a little more info.
I would like to know if the failsafe settings, are they programmable
on all channels, and not just €œhold in position€ with throttle cut?

Yes, each channel can have their own unique failsafe position. There is a failsafe map used to determine if the failsafe for each channel is USER DEFINED or HOLD LAST POSITION. Once the map is set, you set the actual failsafe position live, meaning that you put the receiver in learn mode and move the sticks/switches to where they need to be during a failsafe and a snapshot of those positions is taken and then used during a failsafe condition.

This makes the Xtremelink systems also usable for robotics.

Changed in what way?

Also to add, I am not aware of any changes to the regulations for use of the 2.4GHz spectrum.

The BIPT (The Belgian autority regardig RF use) has put an immediate stop on sales and use of 2,4GHz spread spectrum devices that transmit over 10mwatt for other purposes than Wireless lan application. As for Holland Ive not heard that it would apply here.

At the moment several import companies and retailers are looking to get this ban lifted again.

Ofcom have not announced anything to this effect.

Then we had better re-class the Specktrum as networking our robot to our fingers but seriously they must have a reason for it, This could affect robots going to your next event as most heaveyweights over here now use these at 100mW. Could we get away with pressing the range check button on the back permanently?

This is the document the BIPT (and apparently the dutch Agentschap Telecom is going to do the same) is making the basis of the ban from.

But that document allows the use of 100mW.

Spektrum is a wideband data transmission device.
The document covers wideband data transmission devices.
The type of modulation, etc. the spektrum uses is specifically allowed up to 100mW.

That document is no grounds to ban them.
