2.4 ghz conversion

Im wanting to convert my Futaba 7 to meet club requirements. As theres confusion over uhf use i`d rather fly at the field on something else. It runs on 35 but i dont like that. I want to run on 2.4ghz but after the issues at the field im in two minds.

Spektrum as far as my experience goes sucks, im not a fan of them plus the cost of a radio is out of the question right now. Ive had my attention brought to FRSKY modules. It seems that it is far superior to spektrum and is a simple and cheap mod i can do to my current transmitter. From what i see it hops across many channels unlike the Spektrum and could be the answer to avoid getting shot down.

Has anyone tried these ? What do you think of them ? Is it false economy or a cheap solution ?

Cheers

hope this helps Ian
the guy tells it how it is.if its crap he says its crap.

Thanks Jeff, wow thats fast boot up time, very impressive. I think this looks the one to go for

Quite a few of us are already using Freesky systems
No problems yet (apart from Phil).

It should be an easy mod. for your Futaba Tx

Unlike Spektrum DSM and DSM2 it is a Full continuous freq. hopping system
with easy set Failsafe on all chns.

1 suspected GUID problem has been reported worldwide
when two systems allegedly clashed
but no problems seen or reported anywhere else.

Cost wise it can't be beat atm

Cool cheers, sounds like the best option to go for then

The Two way system may be useful for you
You may well be able to use the return link
for onboard data return.

I have Phil's old one but not had time to evaluate
the return data link functions yet.

4. Function of Two Way communication
a) Two way communication between receiver and transmitter
b) Receiver is able to accept 2 analogue inputs, which can be used to monitor battery voltage, temperature sensor, etc., and transfer them to transmitter. Users can set the Alarm Level of these analogue voltages, when exceed or below these levers, sound alarm is issued.
c) Receiver is able to accept serial data streams from simple 3-wire RS232 port, such information as GPS, altitude, and user developed data can be transferred to Tx without error, and sent at the RS232 port on the Tx.

So these will fit a futaba tx and convert to 2.4 I take it (not fully up on these things) as I have a futaba 35mhz tx here and would be Interested in the conversion if this is the case.
How difficult/easy is this to do ?

iv got a hitec optic 6 gathering dust.this might be away to breath some life back into it.
i will never go back to 35mhz.

If your Tx has a Module its a simple fit

If not it needs hardwiring to the Tx
most make Tx's can be modified to Freesky 2.4Ghz
using the "Hack" module

The internal Mod. is not for the "Layman"
which Futaba Tx have you got ?

I think its a simple Tx module change
same Tx module as the Futaba
I'll have to check

Its the T6EXP Paul I bought it 2 years ago for my son to use on his flying wings, so its not module based, I'm looking at the hack setup then?

yes it will fit Paul,rc model review uses the optic 6 for the review.
8 channel rx for approx £25 is good

Yes. it shouldn't be to hard to do

Even cheaper without the two way link

I like the two way link version. Its not expensive either. I have no ports on my futaba 7 though so ill have to remove my 35 board and hardwire it in there. That will void the warrenty though, so ill do a bit of research and see how reliable they are if fitted like that and see if its worth the risk

here is haw the conversion is done.will give you a idea wots involved.

Thanks Jeff

These conversions are a good way of bringing " life" back to the older 35mhx units which were a constant pain for me due to changing crystals every time i wanted to fly as there was always someone on the same frequency lol.

When i bought my T6EXA i ripped the fasst system out of it straight away and replaced it with the Corona 2.4 DSSS V2 unit , simply because it was more cost effective to do so , Futaba make excellent equiptment but for me the price of the receivers is a little too high especially now when the system is ( as far as it can be ) proven ,and in truth after being on other forums i see as many stories of "high end" equiptment losing their bind as i do of the mid range stuff.

For the soldering of 3 wires ( plus the antennae ) you cant really go wrong , you can even install a simple switch to enable you to flick between the replacement system and the radios original.
