However as Jonesy said he has had a few problems with his.

There is a tail wag on my HK450GT, but that has something to do with the newer HK401B gyros and the DX6i. I will perhaps try the LHGY520, but I will need to figure out how to set that thing up!

Just to be clear, these are the issues I had with my Tarot kits:

- both had the one way bearing pushed into the hub slightly off centre.  Cound have fixed this but did not have the tool.  Replaced with Align Hub and main Gear
- both had slightly bent torque tube - replaced with Align tubes that break the ends off in a strike.
- Only one had some wierd ass hex size in between m2 and m2.5 for the self tapping screws to hold the battery try in.  T6 torques bit fits them perfect so no big deal.
- Second one had the canopy slightly moulded a little too low on the left side closer the the main gear than I would like so I sanded about 2mm off it so it would never hit the main gear.

Apart from those hickups they both fly fantastic.  I spent about $25 in addition to the kits to replace the suspect parts.  Mainshafts and feathing shafts were perfectly straight


It's a shame that Align do not do a barbones kit with out 3gx and electronics..... basically taking the combo out of super combo so we can fit whatever we want.  I gave align servos a good go only to be bitten so I will never a buy a super combo if it comes with Align Servos.  If I did I would flog them off and replace them with something else.

Speaking of servos, I'm really happy with the TGY-306G from hobby king on the tail.  I think this servo would also be great as a cyclic servo.  They are a bit heaver than a normal servo and I think they are going to become a very popluar standard good quality servo as there are a lot of compaies rebadging them now including tarot.

If you want to know the best way to change your one way bearing look no further than here. Its pays to have the correct tools.

As for TX's, it takes some history and I may be missing a few points or even be wrong.

Initially lower freq was used and a dedicated channel was needed since there was no encoding with the signal commands.  Therefore you could loose control because something operated on the same freq. 

Hence the move from 29 mhz to 72 mhz, more channels and less potential for someone operating on the same frequency, but still unencoded.

Fast forward to spread spectrum (frequency hopping).  JR and Spektrum are the same and are made by JR. Original DSM was frequency hopping on the 2.4 ghz band but it did not use multiple channels simultaneously.  DSM2 brought 2 channels simultaneously and DSMX brought true (opinion) spread spektrum.  Futaba used fasst which always used multiple frequencies simultaneously.  All of these are encoded which makes it unlikely to to get channel interference as the TX/RX communicate a good freq on power up.

However there are issues with 2.4 ghz.  Line of sight is best and in reality you should always have line of sight. Reflections of the signal can cause strange things to happen, i.e potential loss of control so best to be away from building etc and this shouldn't be a problem.  2.4 ghz in an urban area is very noisy (everything uses it!) but ideally you shouldn't be flying in a crowed urban area and those devices (routers, phones, video, microwaves...) don't check for what channel they will be using.  2.4 ghz is also more attenuated (weaker signal and less distance) from environmental factors but shouldn't be an issue if you can see your bird.

 Now there are UHF systems that use spread spectrum and improve many of these issues.  However, they have a longer antenna and technically you may require a license to operate on those frequencies.

 For the most part this is not relevant to most folks and is partially my research/needs into FPV.  But I have had some unexplained spektrum things happen as I think a few of you have also.

 So, with a TX that is modular, you can put in many different modules that operate at different frequencies to satisfy your different needs (if you have diverse needs).

 But your doing the right thing, researching

 Hope I haven't sounded like a git from another site...

Someones been spending time on Google

Spektrum is a brand of 2.4Ghz radio designed and manufactured by Horizon Hobby...the same people that in an ideal world would have you binding your spektrum based radio straight up with their spektrum equiped BNF helis lol...... umm guilty

JR Radios used to be Spektrum based using DSM but they have gone away from this and are now using their own protocol based on DMSS which is totally not compatible with Spektrum, DSM or DSMX.  One of their radios from memory the x12 can take a DSMX module.

Your correct about the 2.4Ghz band being noisy.  I do a lot ot RF and WAN installations and this is a constant issue now that there are so many things using RF.

You would probably be surprised that flurescent bulbs emit 2.4Ghz noise accross most of the WLAN frequencies, microwave ovens do the same.  However if your running multiple different WLANS on the same channel or frequency they will happy co-exists and share the bandwidth.  Most of the new wireless routers and access points (including home units) will run on 5Ghz and use the 802.11n specification.  This is one of the first things I do when I suspect a noisy RF environment.

I'm not really interested in FPV but Im interested to see how long its going to take before governments shut it down.  In Australia, last time I checked, if your operating a RC aircraft and it is not under your control using line of sight it's classed as a UAV and is therefore illegal to operate without prior permission and permit etc.

Thats interesting.
The other day when I was at the hospital I got my tablet out to check my email using one of these.  www.telstra.com.au/online-shop/mobile-broadband-product.cfm
Connected ok but after a couple of minutes it stopped connecting and nothing I did would get the connection back even though it had full signal.
Guess there were so many signals at the hospital that it couldnt cope. Ended up swapping the sim to a usb modem and it all worked again.

Thanks for all the input on the radios ken.....your knowledge is vast o' wise one..... .....lol.....seriously though i am torn.....i did have a dx6i that went the way of the doedoe thanks to pilot error and concrete steps.....not the fault of the radio although i did not like the cheap plastic feel if ya know what i mean....but it handled e erything with my nano cpx great.....i really like the futaba.....will let yall know
