Seems that place, plus giant shark dont have the hack module in stock! Does anyone know a UK stockist who has this, or both in stock?

As i wrote this, the site added 7 new units - nice

[PaulRotheram]

Yes, which is why linked to the currently available telemetry module. you use select to use it in 1-way mode, not two way(telemetry) mode.

T9 hobbysport are the Uk agents for Frsky-rc. they run this: http://www.frsky-rc.co.uk/

Thanks for the info!

Can other receivers on there work? the one suggested seems to be out of stock.

just done my gemini II easy peasy , just follow pic on page 2

[PaulRotheram]

I've just finished up on my KO espritt II and can confirm how easy it is! Very good system, very easy to do, very much reccomended!

I'm planning to put the V8R4 receiver in to my old KO receiver box to add some protection and slightly more water resistant.

Once my wiring is complete ill post a picture up.

Great stuff!

I just shrink wrapped my receivers. I've also taken the 90 degree bends out of the servo lead pins and stood them up vertically. Makes the receiver foot print far smaller and easier to use.

[PaulRotheram]

How did you go about doing that? That is something i want to do as i dislike where the wires are sitting because of how they are situated in the receiver.

Anyone got any ideas where to buy the conversion from and what receiver is needed, plus anyone got pics of a Sanwa Gemini conversion?

The module mentioned in this thread was available here

http://www.giantshark.co.uk/frsky-24...-p-405206.html

However there is a link in the description saying that it would no longer be available. And you should check out the following item instead.

http://www.giantshark.co.uk/frsky-24...-p-405725.html

Unfortunately at the time of writing it is showing as out of stock

As i am recently returning from a long hiatus, i have no idea how the two way link works with rules etc, or if the new module is as easy to install as the original poster mentions.

Good Luck

Theres a circuit board pic on page2 #33, would be nice to see pics from a oOplers conversion, including binding button/aerial etc.

[Welshy40]

Cheers, did some looking and found two in and around hong kong so bought them both. Now just hope they are really in stock and hope i get them as my Sanwa Gemini is going to get an upgrade. Cant understand the computer settings and prefer the screw driver settings on this, much simpler and easier to use.

[Welshy40]

Out of curiosity why do we have to remove the metal aerial? Why cant we just attach the connector to the bottom of the aerial.

Check out my post #131 on page 7 of this thread.

I put a link to my photobucket showing my Gemini II internals as I was doing it.

Hope that helps

Nice work tynhead, I missed it, still to do ours . Be nice if a list of converted transmitters and url's could be included in the first post., nudge cardnim

Bought a used modified 2.4ghz ko esprit 2 type R but wasnt done perfectly, the module was left out and the hole was taped and the aerial hole was left as standard and only half of the plastic aerial was showing. So thought may as well do a full upgrade so have changed all the screws to give it a nicer look, and had to drill out the aerial hole, like stated on page one and only issue i had was making the aerial screw into the inner connector, first attempt was good but didnt space the inner nut out to account for the gap that wasnt drilled but when i did that it fitted perfectly. Thanks for this info and pics as it really is so. simple.

Now to wait for the bits to arrive so i can do my sanwa gemini exerd.

Is it possible to do the same conversion to a Esprit III ? I did it on a II no problem.

Also, I notice the new modules have a little switch - what do you do with that?

Yup, the esprit 3 converts perfectly. you can hide the hack module in the space behind the module slot, if you remove the data board that't behind it. just use the three pin lead that goes to the original module pins and solder it to the new hack module and plug it into the main board. The bind daughter board sits lovely behind the data/model expansion slot on the back, just hot glue it in.

The new modules come with the 1-way/2way selection switch. Just remove this and solder the pins on the reverse side of the white 3 pin connector, to set it permanently to 1-way. You don't need the telemetry feature. buzz it out yourself so you are sure, but its the outer most two pins that you need to short, leaving the 3rd inner most pin on its own.


I'm just working on putting one inside a Ko RF-901S module case, so a transmitter can be left as standard, but still use the hack module.

[Welshy40]

So firstly where can i get spare aerials?

Secondly the dht thats available, how different s job is it compared to the older one? Im tempted to fit it into my 3gr futaba 40mhz
