2.4 or 35?

[Flypoppa]

I have at present 2 spectrum TXs, a DX6 for my park flyers and a DX6i for my FPV and the rest.
I am looking for better range.
If I want to stay 'legal', would I be better off with some 35mhz kit.
From what I am reading, am I correct in thinking that 35mhz can now be with these duel conversion synthensized RXs free from interference from other 35mhz useing the same frequencys?
Not that there are many other flyers at my flying field.
If I were to think of going illegal with more power on my 2.4 (as if I would. :P) Such as one of these power amps. Are they that easy to fit? (Yes I can solder and know what end of a screwdriver to use.)
I know that I could increase the range via the RX on 35mhz, but could it be done on the 2.4 RXs?

35mHz
Single conversion with a tight IF is OK for adjacent channel rejection but can be affected by out of band image transmissions.
Dual conversion deals with the out of band image tranmissions but if someboby else is on your spot frequency, especialy at another location that you may be flying towards, then its plastic bag time for your plane.
The use of 35mHz for FPV use depends on your information of who may be opperating in the local area. Don't forget that you need to make sure that no one is going to be on 35mHz for over twice the distance from your location. So, draw a circle on a map at least twice your expected range of opperation and then its a case of checking it out.

2.4gHz
Could point you to various sites for this sort of mod but I believe, from what I've read on other forums, that this was frowned on in a big way.

Thanks for your answer Orca. It was only after last Tuesdays downwind drama that made me think that if I had better range with my DX6i I could have saved myself.
778 yards was out of LOS by my spotter. I now ask myself was it panic flying in trying to get home, or was it all down to pilot error?  The wind was a main feature in the drama.

35MHz still uses fixed spot frequencies so anyone else on the same frequency will cause interference.  :(
I'm cannot think where you got hold of that idea about dual conversion synthesised receivers.

Not a good idea to use a power amp. You could upset a lot of legitimate users by swamping their signals. If you do decide to, you might also like to add a flashing sign drawing further attention to yourself.
:P

I'm glad to see that you were really trying to avoid the buildings.
Looking at the heading info on your OSD it appears that you launched downwind or at least not into wind. If you find yourself struggling to return to launch point due to wind strength you could try a couple of things.
Turning into wind will also make the model climb. Use the height gain and our old friend (or enemy) gravity to dive and claw your way back. It will be a helter skelter type of flight though.
You could also try tacking or traversing so that your model is not facing the full force of the headwind. The wind can of course blow your model sideways beyond the thrust of the prop to counter.

I agree with orca . But i think its more a case of horses for coarses in the respect of Spektrum (which i still do like and own  :D) have never been any thing more than a park flyer's TX with a relative short range .
When i started to look into what was and is avalible Spektrum didn't have any thing new to bring to the market and seemed slow on the uptake on fhss but then released DMX and wanted £70 for the upgrade.  :(
 That then narrowed the field down so i ended up getting a futaba as i wasn't stuck with only one brand of RX as you can swap and change modules with these so now i have a full range of brands and two different RF frequency's i can use either 35mhz or 2.4ghz  :D
and it  is still compatable with my spektrum models so no need to upgrade any RX's
 As for range in the joe public price range i don't think you can go far wrong with the futaba fasst system as the range is nearly double of that of my spektrum gear and to be fare i do like my fr sky stuff (which again has more range) and will tend to stick with that  :D

First I would like to tell you that it was launched into wind. As I was heading skywards I did not notice that it had turned downwind. Again I say it was my fault for not noticeing. It was when I reconised the landmarks that I Realised and turned into wind. But by then it was too late as it only took seconds to get to the point of no return sort of thing.
Thanks people for the advice for the TXs.
I have been looking at the 'Sky' stuff at 'Giantcod'. Out of stock at present.

Seconded Dave!

I also got a Futaba 9C on 35Mhz.  Added in 2.4Ghz and DragonLink UHF modules...

Now I can run on any control frequency...  And I have the options of using 1.3Ghz or 5.8Ghz VideoTX without getting or causing anyone interference!

There is now a UK version of the EzUHF which operates on 459MHz (a UK only dedicated frequency for model control) - have you seen that?  Its bloody pricey so I wouldn't blame you if you've ruled it out (its bloody good though).

All the best

sounds interesting - what sort of range would we expect from the uk EzUHF?
need any testers?
cheers

On the low power setting ( uk legal ) the range would exceed several km no problem, which of course is all we need and more for flying within UK limits :)
