Spektrum DX6i / BR6000s

well we were testing the BR6000 fur use in an antweight robot and wanted to see how far we could push it. As it turns out, the receiver can take a lot more than 6V (at 8V the BR6000 is still fine even), so we could run servos at a higher voltage as well. But when we had it on a steady 5V lab power supply we measured the current draw of the receiver in rest and during servo activity. now we expected with the S75 servo for a drastic increase in current draw. But even in rest the 145mA is quite a lot, over 3 times what my GWS RX did.

Putting a capacitor on receivers is always a good idea in RC branches where a lot of current is pulled. Its worth checking into if it is the problem in Andys case.

Any ideas how the receiver voltage is monitored?

As I said in the DX6i manual it says 4.8V is the minimum. It doesnt mention it in the DX6 manual.

If its monitored from the Tx as part of the software then.................

Out of interest Woody, where did the 3.5V figure come from?

Well we monitored the voltage during our tests by looking at the gauge on the lab PSU. current we measured with an oscilloscope.

Of course that is more problematic in the field. Still any well charged RX battery (5 cel preferred) should suffice. In a heavy a lot of roboteers used those 6V SLA blocks.

At only 7 grams, the AR6000 receiver is specifically designed for lightweight, electric powered planes and helis. Better yet, it will deliver reliable range exceeding that of any other receiver sold specifically for parkflyers.


Specs
Type:Park Flyer Only
# of Channels:6 Channels
ModulationSM
Band:2.4GHz
Dimensions (WxLxH):39 x 39 x 9mm
Weight:7 grams
Voltage Range:3.5V-9.6V
Antenna Length:3.75 in (2)

I assume the BR6000 is exactly the same specs.

It is indeed.

Does anyone have a list of their events how many people use 2.4GHz in their robots and how many are on 40MHz?

Leo,
As I recall, at the UK Champs there were only 3 machines on 40Mhz. (and 2 of those were feathers)

does that mean storm force was the only heavy on 40mhz

yes

your lacking in technology lol

Wasnt edgehog on 40MHz as well?

[botmad]

Spektrum DX6i / BR6000s

yes it was

It was only 3 or 4 machines using 40mhz, rest on 2.4ghz. I think transmitter control might turn into removable link control. As there is no need to keep the TXs to stop freq clashes, but maybe just links to stop too many live robots testing in the pits?

I disagree, most of us have spare links anyway. The best way to keep people safe is to have transmitters handed in.

[leorcc]

Spektrum DX6i / BR6000s

I agree on handing in the TX. I was asking to find out what the ratio 2.4GHz/40MHz is nowadays.
