E-Sky EK2-0705B 4 in 1 Controller

Remember Me Forgot Password? Mar 24, I didn’t use it for a long, long time and when I tried to use it, I follow the routine of turning on transmitter, then plugging in battery.

It goes red, then green, then starts to randomly spin the rotors and servos and starts blinking red and green – a very dangerous situation. The transmitter appears to still have some control as the servos partially respond to commands they swing back and forth to extreme ek2-0705n in response to small changes in the stick.

Moving the throttle moves the servos sometimes. It just seems very confused and glitching out like crazy. I’ve changed the TX batteries, check my heli batteries and used a spare. Is my EKB hopelessly busted or is there anything else I can check? What is confusing is that I do have partial control, it’s just seems it has crossed channels or responsing to some random input.


It sounds like bad connections in the crystals. Take them out and re-seat them a couple of times. Even spreading the pins very slightly outwards will give them better contact.

Mar 25, I tried reseating the crystals, but it still behaves erratically. It is behaving like it is getting a signal, but everything is mixed up.

What are the chances that something is wrong with the transmitter instead of the receiver? Could some other signal interfere? I turned off my Wifi router and that didn’t have any effect. I have DECT panasonic phones. This is 72 Mhz, so I don’t think I have anything to interfere.

Not that it means the same thing is happening to you, but I have an Esky RX that does something very similar. ELE works as it should. AIL is stuck full L.

THR is random, so much that it will not initialize. The same TX still works with another aircraft. I am having the same issue with Esky 4in1 unit FM35Mhz,i.

Mar 26, Exky for the suggestions. I took a look at the TX crystal socket, I can see the sleeves inside of the sockets, so it looks ok. None ek2-0075b my controls work consistently.

It does appear to arm as it goes green if I manipulate the controls, but it just wildly spins the propeller at random times and speeds. Unfortunately, there seems to be no way to pinpoint whether the TX or RX is bad. Maybe I can send my RX to somebody to try out??? Return to Coaxial Helicopters. Posting Quick Reply – Please Wait.
