FrSKY ACCST technology is proven, approved by many model associations, tested and reviewed as the leading Chinese 2.4Ghz R/C Technology. If you think DSM2 or FASST is the best, think again!
New FrSKY ACCST (Advanced Continuous Channel Shifting Technology) gives you secure radio communicatios in 2.4Ghz band. ACCST 2.4GHz system shifts 80 channels around hundred times per second in the 2.4GHz band. This means that the system is completely resistant to interference in that band.
Features: Advanced Continuous Channel Shifting Technology (ACCST is our advanced tecnology it shifts channel hundred times per second and there is no signal conflicts and interruptions) robust frequency agility. Easy to bind and very fast link-up. Excellent reboot time. True Diversity with two antennas. All channels can be programmed with Failsafe, quickly and easily. Quick and extremely stable in performance. Precise and smooth servo response. Extended range (1.5km-2.5km).
Receiver Specification: Operating voltage: 3.5v~10v Power consumption: 50mA Resolution: 3072 Latency: 18ms (FS) 9ms (HS) Number of channels: 6 Range: 1.5km Dimensions: 42x22x11mm Weight: 7.1g
Included; 1 x 6-channel receiver D6FR
Compatible with FrSky 2 way telemetry modules: DFT, DJY, DHT, DHT-U
...not sure what you mean by wrong channels but channel mapping to stick position is settable on the TH9X and Turnigy 9X under system menu "stick set"
the small numbers above and to the left of the circles indicate which channel is associated with which stick movement
This receiver includes 2 antennas. They seem to be the same as FRANT15. They are connected by pushing the connectors together (similar to laptop wifi antennas). No need to solder them. Unless you have damaged the original antennas, no need for the 15 cms replacements.
After buying two of these receivers I have found that the specifications listed in the manual are not correct for the analog inputs. The manual states a 1:1 ratio for the AD2 input but it actually has a 6:1 divider hardwired internally. This means existing accessories like the FrSky voltage monitor cable or Flytron display will give different readings with the D6FR compared to the original D8R 8 channel version.
It is possible to work around these differences but it means the D6FR can not be considered a direct replacement for the D8R for smaller aircraft. Apart from this issue, it still represents a great value receiver capable of sending telemetry data back to the ground.
One final point: note that unlike the D8R 8 channel version this D6FR has no serial data link for telemetry and is also not firmware upgradeable by the customer.
