Gate post broken

Sun Aug 27, 2017 8:42 pm by Gary M Jones

Just in case anyone is not aware, the main gate post at the field entrance is broken at its base just at ground level. ( the bolt side post) The post is only supported by the fencing attached to it. If the fencing fails then the post will fall and …

2.4ghz regs

Post by Mark Barnes on Wed Jan 14, 2015 4:52 pm

This story is doing the rounds this week, does anyone have any more info



"This month new regulations come into force regarding the use of 2.4GHz r/c transmitters and receivers in the EU, titled EN 300 328 (v1.8.1).
Two things you really need to know
1) all your existing kit remains fully legal to use because of the grandfathering rules
2) all the different brands(and in some cases protocols within brands) are affected differently, or in many cases not at all.
Here is a summary of how it is affecting the major brands and their protocols:

Spektrum DSM2 – New Spektrum TXs sold from now on will not transmit DSM2, which is not compliant with the new regulations. Since all Spektrum RXs sold have been DSMX for some time, this should not have any effect on current users unless you have a stack of old DSM2 only RXs and want a new TX. Workaround – buy a Taranis and an OrangeRX DSM2/X module from Hobbyking.

Futaba FASST & FHSS – FASST definitely was not compliant; opinions vary on whether the S/T-FHSS protocols were or not. Either way, Futaba have released firmware updates for the two current FASST sets on sale in the UK (14SG and 18MZ), and documentation indicates changes were made to the RF firmware for all three protocols. These changes seem to work ok with genuine Futaba RXs, but the reverse engineered FASST RXs from FrSky and others now do not work with the upgraded TXs. FrSky have stated updated firmware will be released for their RXs very soon to address the issue.

FrSky ACCST – new firmware has been released for the X-series RXs, XJT module and Taranis TX. Existing X series will not work with an upgraded TX, and new X-series RXs will not work with a Taranis that has not been upgraded to the new firmware. D series and V8 (non telemetry) RXs seem unaffected and work with an upgraded TX without any changes; no D/V8 RX firmware updates released as yet.

Hitec AFHSS, Jeti Duplex, JR DMSS, Spektrum DSMX – already compliant with new regulations.

Graupner HoTT – Initially believed to be compliant, but now there are some question marks.

Multiplex M-Link – Unknown, but there seems to be little buzz online about non-compliance and Multiplex were deliberately late to launch their 2.4 offering due to uncertainty about the regulations, so likely to already comply."

Interesting info. that Mark, all in all all non compliant with the exeption of
Hitec AFHSS, Jeti Duplex, JR DMSS, Spektrum DSMX – already compliant with new regulations. Luckily I have all genuine Futaba receivers.

All I know is that the new protocol means the transmitter has to read the full band before transmitting at all whether it channel hops or not. Personally not bothered as it's not applicable to existing gear.

Updated 18MZ firmware, now fully compliant with current EU legislation it only effects, 7CH mode and S-FHSS as FASSTest was already compliant. 14SG V5 firmware is available from Ripmax, US website for 18MZ.

There's no need to update s/w. This standard only effects equipment sold new after the 1st Jan. Existing equipment only has to comply with what was in force at the time it was sold

Yes Gary.

I update on a regular basis anyway, it comes with other updates not just the LBT upgrade. I don't use copy receivers for futaba.
I have plenty of the orange using a DX6i.

Understood Allan, I read the doc as well.

Weatronic radio gear complied with these "New" regs as far back as 5 years ago.
Their system provides an output to a monitor, if you want and can show snaps of the  whole 2.4 spectrum.
DSM2 shows as a permanent pair if channels which stay fixed until the TX using DSM2  is switched off and back on for another flight. when it locks onto a new pair.
