Well there is now an expensive solution of sorts for the failsafe on all channels for dsm2 users who run heavyweights. The AR7100 has an option to put all channels on pre-programmed failsafe settings (just as the BR6000 has).
quote:
Preset Failsafe
When the transmitter and receiver are turned on and after the receiver
connects to the transmitter and normal control of all channels occurs,
if loss of signal occurs preset failsafe drives all servos to their preset
failsafe positions. Some pilots prefer this method but normally
SmartSafe is recommended for helicopters. When the signal is
regained, the system immediately (less than 4 ms) regains control.
Programming Preset Failsafe
During the binding process the bind plug is inserted in the bind
port, and then the receiver is powered up. The LEDs in each receiver
should blink, indicating that the receiver is in bind mode. Now before
binding the receiver to the transmitter and with the receiver in bind
mode, remove the bind plug. The LEDs will continue to blink. With
the control sticks and switches in the desired failsafe positions, bind
the transmitter to the receiver by putting the transmitter/module into
bind mode. The system should connect in less than 15 seconds. The
receiver is now programmed for preset failsafe.
Note: Failsafe positions are stored via the stick and switch positions
on the transmitter during binding.
Before each flying session, and especially with a new model, it€™s
important to perform a range check.The downside to this solution is that the receiver itself is about as expensive as the DX6i transmitter, and way overkill for our purposes.
Well Peter Waller is testing the situation on his setup and so far he came up with this:

Leo I think my main problem was trying to bind three recievers on one model and that was causing the unbinding problem that I was experiencing even on the 6100.
I have now done about 40 on / off cycles on the BR6000 / DX6i and although connecting is sometimes slow I have not lost binding. I am testing at 6v in case it is a problem with the supply voltage as the 6000 cant go below 4.8v.
I have now done well in excess of fifty power cycles and although a couple of time the system failed to link up recycling the power eventually got link up showing the Bind was still intact.This on the Robotwars101 forum. http://www.robotwars101.org/phpBB/viewtopic.php?p=27576#27576http://www.robotwars101.org/phpBB/vi...?p=27576#27576
I have now completed over 75 on off cycles of my BR6000 the last 15 back down at 5V and still been unable to lose the bind. On a couple of occasions I thought it had happend when it failed to connect in 5 mins but after a couple more power cycles it was again connecting. These test are all done on a stabalised power supply with no large motors switching so it may be that dips in the power rails cause these problems. The time taken to connect means I will not be running my DX6i with a BR6000. As far as ants are concerned the failsafe on the throttle channel which we use for our weapon is enough. Having said I have modified the software in my speed controller to give failsafe on all three channels used. On Binding I not only set the throttle stick fully back but also full back trim then in normal operation set the trim back to centre. This means the failsafe pulse width of the throttle is out side the normal range and can be detected and used to shut down the two drive channels. Hope this is of some help.
Ive had enough with my DX6i now and am now saving up for a DX7. Spektrum should be ashamed of themselves for releasing what I can see is a product still in Beta testing and they should really offer full money back for anyone who has bought a DX6i who wanted to use it with the BR6000 Rxs
In fairness to Spektrum the DX6i works perfectly with the AR6100 and presumably other DSM2 receivers and only seems to fail in its backwards compatability with the older receivers. Having said that they are advertised as being compatible and Spektrum are not doing themselves any favours by their apparent lack of action or even interest.
we have spoken to them to try and get a DX7 transmitter and rx set so it would be cheaper(ie like the dx6i with no servos etc) but no uck so far. we will keep you posted.
After the system makes a connection, if loss of signal occurs, the AR500 failsafe drives the throttle servo only to its preset failsafe position (low throttle) that was set
during binding.
€ All other channels receive no output pulses/ commands,and are not active during failsafe.
Seems that the AR500 reciever operates differently to the AR6000 .... rather than outputting a valid signal in failsafe it removes the signal thus... IMO ...the AR500 should be compatible with a std plugin failsafe.
Hmmm, i wonder why they never mentioned it to us during one of our recent conversations about the DX6i compatability.
Well enquire about these on tuesday and try and give some a test!
