Hi.

I crashed my Trex 600NSP...i'm telling u that heli is
an animal!

in about 5 miters above the ground the tail began to get crazy....
instincly i hit the Hold,the engine remined at high RPM.
Apparently the reciver(AR7000) lost it's binding....
even those i'm using a capacitor.

The dammage is about 140$ (not including blads)

Now i don't now what to do....I can't take the chance
that the lightning will hit twice...

**The small reciver is located 3 inch in front of the main reciver
and it's antenas located 90 degrees to the main reciver's antenas.

THX for helping...

I've never had an issues with DX7.

now what receivers are you using and what version.

earlier ones have been know to have issues. I only run v1.6s.

Yes, the DX7 is reliable, so are its receivers.

The tail went crazy and the engine remained at high RPM, and you're saying the RX lost its bind.

The capacitor is the wrong solution if you are seeing power supply problems. The correct fix is to use a suitable battery for your system, and/or a suitable regulator. The capacitor does not do anything with "binding", it tries to maintain a constant power supply voltage under load. However, if you're using the current crop of good digital servos, the cap will be next to useless, as the current demands of the higher-speed digitals can far exceed the ability of that little external capacitor to maintain its charge during a low voltage spike.

Did you have to re-bind the RX the next time you applied power to the receiver? If not, the RX didn't "lose its bind".

Generally the ONLY way to screw up a bound receiver is to accidentally press the TX bind button when you're applying power to the system. This is easy to do if you're one of those who lays the TX on its back on the ground, and turns it on. The TX bind button protrudes beyond the back of the TX case, and it's easily accidentally activated (also if you use a transmitter tray that doesn't have a cutout for that switch). If the TX bind switch gets pressed AFTER power has been applied, it functions to reduce the RF output of the transmitter for range-checking purposes. If you accidentally push the bind button while flying, you won't lose binding, but you will suddenly be flying at a greatly reduced output power level, and it is possible to fly out of transmitter range. In that case, however, the receiver would go into fail safe mode, and had you properly set up the throttle fail safe setting, the receiver would drive the throttle servo to its fail safe setting.

If you have CORRECTLY gone through the bind procedure to set the throttle fail-safe position, if the RX loses signal and goes into fail-safe, the throttle will go to your preset position.

If your receivers have newer firmware installed, the yellow LEDs on both receivers would most likely be blinking following a low voltage condition encountered while flying. Additionally, with the latest firmware version in your RX, if the power supply to the RX should momentarily drop below the safe minimum operating voltage and recover during flight, the receiver should re-boot and re-acquire the TX almost instantly, there is very little, if any, delay

First of all thx for helping.

I made the fail safe settings durring the binding and it works well.
Now...if it's not the radio ststem what could it be? :S
the regulator suplies very stable voltage of 5.8V
the battary was about 7/9 full.
Fist i thought it's the tail servo. but it's apparently working fine.
And what if it was the tail servo, why i was getting no control
of the heli? :S...and the throttle didn't get into hold...

I'm not talking about the throttle responce after the impact cause
there is an option that the rods became crooked.
P.s
How can i know what is the version of my AR700?

Thx again.

To check the version power up the transmitter then power up the reciever. They should connect after a few seconds and the lights should come on steady.

While leaving the transmitter on turn the reciever off and back on.

One of three things will happen.

It will take several seconds to connect, the lights will then come on steady. This is the oldest verison

It will connect instantly but the lights will stay on steady. This was the first firmware update and is one out of date.

It will connect instantly and the lights on both recievers will flash. This is the latest firmware version.

If by chance one flashes and one comes on steady that means the firmware is mismatched.

If you have anything but the latest firmware on both main and satilite recievers I'd reccomend upgrading them by sending them to the service center for your area.

I probebly have the lastest version.

When i turn the transmitter on than the RX it takes 1-2 second untill the system begen to work.

When i turns only the RX off,than back on it takes a few second
untill the RX getting to work.

I didn't understand....what does it means that after i'm shutting the
RX off than back on the main reciver's led is blinking, but the small reciver's led is stable.

It means you have a mismatch on the firmware and in that case I really reccomend you get everything updated.
