Title: Frsky v Spectrum
Post by: pcnukem on December 09, 2011, 06:21:02 PM
Hi all
Does anyone know much about frsky? Im using spectrum 2.4 at the mo but thinking about getting a frsky module to plug into my Futaba 9c.
Are they as good as Spectrum and as good range.
Thanks in advance for any info.
Paul.

Hiya Paul
               Frsky walks all over spektrum as i have sold every last bit of there stuff and it's Frsky all the way for me

The range is nearly double that of spektrum depending on your surroundings and tbh i would put futaba at the top frky and then spektrum
Out of all the major manufacturers i think spektrum where the last to come out with fhss and accst  with their DSMx which was very flawed and thats why the where left behind just resting on a brand name whilst everyone else knew dsm2 was so over rated
As for pricing i don't think they where too happy when HobbyKing came out with the orange brand which must have hit there sales hard when you can buy a simular unit at a fraction of the price which is just as good BUT i do think Futaba are one of the worst for this as you put the word fasst on something then think of a figure then double it  :D
If you where starting over i would say get a Turnigy 9x (better get a preorder in) and a frsky module or the new screen with version 2 software on as it's  spot on
The one BIG NEGATIVE thing i will slate frsky for is they bring things out and the manuals may be weeks later or they will update the whole unit so it's a fast moving but it does now seem to be slowing down a bit the manuals are still not very clear as they are written in chinlish BUT the are up there when it comes to sorting out any issues you may have and very quick

For LOS I use Spektrum.

It is crap, yes. However, you can use all the BNF and micro models and such. You can't do that with anything else.

True enough Sheldon, unless you change out the cack Rx and speed controller in favour of something more compatible... e.g. 4 channel Rx, etc.

End of the day, Spectrum is a marketing tool.  Once you have a spectrum Tx, you are basically stick and carrot towards buying more of HobbyZone's stuff, like over priced BNF planes, etc.

Just a thought ;)

The plus side to all this is in the past you where stuck with having to either buy a Spektrum unit or module But the good news it come March time Hobbyking are releasing their own unit  :D

DSM2 (old speck) isnt frequency hopping therefore you get some strong interfernce on one channel and the system will lock out (happened to me a few times flying fpv)  

DSMX is slightly better as it is frequency hopping but the receivers are bloody expensive compared to frsky
(frsky 20 pounds for a 8channel long range one and spektrum >50 if you want range over 500metres)

Frsky is cheap,frequency hopping and has good range (1-2km, some have been 6km on the patch antenna for the module)

I would buy a 9x from hobbyking or the old 9x called flysky as they both have module slots.

In the past months i have been deciding and i know spektrum isnt right for fpv. I brought a frsky diy kit (£20) and a 8channel receiver to install into the dx6i but I happened to see a graupner mx-12 (4km range) transmitter going for cheap (150 euros) if you want the link -http://shop.lindinger.at/product_info.php?cPath=1703_1705&products_id=90200

Hope this helps :)

Sheldon is right- Spektrum for parkflyers and mircos
Frsky for more range and reliable rf link

Paul.

I have used FrSky modules to move from 35 MHz to 2.4 GHz this summer. I used the DHT module for my Futaba 6EXA Tx and the D8-R(2) for the receiver.

It has two useful features among others.

1) The receiver transmits data back to the Tx. Initially this is usd to send RSSI info. The transmitter module will sound an audible warning when the RSSI is low in the receiver. Now I dont think I would like to fly without it!

2) You can set it to reduce the range artificially so that you can test your range and the warning system.

Beyond that it is also possible to send other data to the transmitter from the receiver (and vice versa)
I envisaged using that to provide a OSD at the Vrx end from the model. Alternatively you could record the gps data. There is also telemetry stuff available.

Looking at frsky site now there is a wide range of other receivers and other goodies.A couple outputs all rx signal data on one line... which makes grabbing that info by a microcontroller much easier and is AFAIK useful for quadcopters etc.

As its the only 2.4 GHz system I used I cannot offer comparison but I am very happy with it.

regards
Andy

As you now, I be keeping my Spectrum DX6i for the BNF minis I have.
and converting the rest of my LOS plans and for my close rang FPV, Futaba compatible FrSky RX.
Hail PK and DPS Dave for pointing me in the right direction. :notworthy:

Thanks everyone fo your replys, I'v got myself an Frsky V8FT module to plug into my Futaba 9C and 3 Frsky V8FR recievers all delivered for £61 so well chuffed.
Im thinking about getting a Hobbyking Bixler EPO 1400mm and was woundering if this would be a good model to start me off and give me confidance in the air.
