PROBLEM

Spektrum DX6,7,8
( May 2011 )

           
The following has been reported as a result of various different problems with the new DSM-X versions of these radios :-

"DSMX transmitters operating in DSM2 mode "

"The Spektrum Team has been investigating sporadic reports from DSMX transmitter owners using their products in DSM2 mode. We have discovered that in some rare instances, DSMX equipped transmitters with the Product ID (PID) within this bulletin, may have a backwards compatibility issue that could cause a "hold" with the following superseded DSM2 receivers: AR500, AR6100, AR6100E, AR6110, AR6110E, AR6200 and AR6300."

Note: This bulletin does not apply to DSM2 ONLY transmitters.     

The PID is located in the battery compartment of your transmitter.

DX6i/DX5e/DX4e: 
PID: HS010, HS011, HH011, HT011, HT012, HE012, HE101, HA101, HA102, HA103, HA104, HA105

DX7: 
PID: HA103, HA104, HA105

DX8: 
PID: HS008, HS009, HH009, HH010, HT010, HE010, HE011, HA011, HA012, HA101, HO102, HO103, HO104, HO105
  

Spektrum DX8
( April 2011 )

           
The following has been reported as a result of various different problems with this particular radio :-

"If you update your DX8 using a download from the Internet or it goes back to Horizon Hobby for service you MUST REBIND ALL models before using them. Failure to do this may result in reduced range. Obviously a range check must be carried out after rebinding and before flying. 

Apparently Horizon Hobby are going to start including this info in all future DX8s and with returns after service."
     

Interceptor 400

      
If you purchase a kit and the bolts that hold the tail blades to the grips only just fit through the grips you MUST replace them with longer 2mm bolts that extend all the way through both sides of the blade grip to avoid tail blades flying off.
     

Interceptor 400

    
To stop the tail gearbox from rotating, you need to fit longer 21mm bolts and also use nuts on the other side of these to lock the tail gearbox securely onto the boom. 
          
Gyros on many larger helicopters         
Quite often reports are seen in the forums on poor gyro performance, with random twitching etc making tail control difficult, even with "good" gyros.

The most common cause for this is static electricity building up at the tail due to friction from the rubber drive belt etc. It is therefore a good idea to ground the tail to the motor or engine frame, and also to mount the gyro on two foam stickies with a thin metal sheet between them to absorb this unwanted static electricity.

The other way to cure it is to convert your helicopter to Torque tube tail drive if that is possible.
