FUTABA 2.4GHz NOTICE

Following reports from members of problems with a few Futaba radio sets on 2.4GHz, we contacted Ripmax,who are the UK importers for these sets, to see if they could give the BMFA any information on the situation.Below is the official statement that has just been issued by Ripmax on this matter.

We recommend, that before further use, owners of the 2.4Ghz sets or modules referred to in the Ripmax Press Release seek clarification, as indicated by Ripmax,as to whether their particular set or module is likely to be affected by this problem. There are obvious safety implications that must not be ignored.

Ripmax Press Release

It has come to our attention that a very small number of incorrectly coded 2.4GHz Futaba 6EX transmitters and TM-7 modules have been manufactured, and that some of these have been sold prior to Ripmax becoming aware of the situation. It appears that these faulty units transmit using a default serial code, and that if two or more of these units are in operation at the same time, they may cause interference with each other, however they cannot affect correctly coded units. At the time of writing, the problem had only just been identified and Ripmax, together with Futaba, are investigating the situation, the very latest information will be available on our website, at www.ripmax.com, or via your local model shop, / Hobby corner

SPEKTRUM 2.4Ghz

QuickConnect Voltage Recovery System for DSM2 Air receivers

Performance modelers have known for some time that care must be taken to assure adequate power supplies for their airborne system. It’s true for all radio systems, but it’s doubly important when using high-performance servos, flying harder maneuvers, and trying to save weight with inadequate batteries and/or regulators.

Spektrum systems are designed with an operating threshold of 3.5 volts, and lower voltages cause the system to shut down. When adequate power is regained (usually the drop is momentary), earlier Spektrum systems re-boot and rescan for two previous channels before control is restored – a process usually requiring two to five seconds.

The new QuickConnect feature, however, eliminates the scanning delay and restores control almost instantly. We have been integrating this upgrade into receivers in a running change. Here’s how to identify if your receiver has QuickConnect:

With the system operating normally, simply switch the airborne power off, then on. If your system shows virtually no delay in regaining control, your receiver includes the QuickConnect feature.

Flashing LEDs indicate low voltage alert

QuickConnect allows most flyers to fly through common low-voltage situations caused by insufficient battery "headroom" – in many cases, without knowing a problem ever occurred. As a result, Spektrum engineers decided to program the system so that the receiver LEDs would flash, should the QuickConnect feature be triggered in flight. This can also be demonstrated on the bench, by toggling the airborne power.

If your receiver is missing one or both of these features, first off, it's important to recognize that the vast majority of flyers using "normal" servos with "normal" properly charged batteries will be unaffected by low-voltage issues. The best fix, however, remains assuring adequate power supply to the airborne system with sufficient voltage headroom.

SPEKTRUM DX 6i Service Bulletin

DX6i Evaluation and Product Inspection Request
UK customers
This product bulletin has been provided for consumers who have DX6i radios with particular attention
to those radios with date codes of 809E, 810E, 811E, 812E. Please check your radio using the
evaluation process below. If you find a irregularity with your radio, please return it by completing the DX6i Product Inspection Request Form provided within this document.
How to know if your product needs to be checked?
We would suggest all radios should be checked but radios with a date codes of 809E, 810E, 811E, 812E should be carefully checked.
