RCKatty - I was only responding to the bind plug requirement.

But since you brought up the issue of a hack versus going for genuine 2.4 radio, here are my observations.

1) Many people may not have the skill/guts to do it.  So someone like Sai doing them before shipping to a new buyer may work.

2) You lose any sort of warranty by the radio manufacturer. But then who really sends radios back to manufacturers these days ?

It looks like if you radio is already like a year old or so, this is a good trick (assuming you can manage to do it cleanly, without dripping solder on the rest of the components etc )

Atul ,

Be careful in what you pick the Module Ismail has is for Module based Transmitters.

What is needed for the 6 exa is the hack Module.

Katty /Anwar ,
We are the budget oriented players of the RC Segment we are not talking big time so we can live without a few features  like pressing a button on the tx etc and using a bind plug a manual method instead .
The conversion was not really that complicated all we are trying to do here is to  look at affordable 2.4 G options  for those who do not want to nor afford to buy expensive 2,4 G options .

Those who can afford or want  JR , SPEKTRUM , Air tronics , FUTABA  etc are not  persons this thread is aimed at in the first place .

So guy's this sort of a thread is for JANATA CLASS aero modelers   not for Air travel type's and largely to DIY types ( build and fly ) not buy and fly types . We are willing to put in a little extra effort ( AKA manual labour  ) to achieve what we  want ie best bang for the buck in our opinion .

BTW the Capacitor or the Voltage regulator is a simple device included in the event of a rx voltage drop , it is a kind of backup  again a Janata class solution . May be you could also adopt it on your super brands

We buy second hand radio's ,  reuse  radios junked by others , pull out junked  stuff and try  to use every small thing we have  to the maximum , this is our psych , we make models out of advt board and scrap , well guy this is the class of aero modelers that ASSAN is meant for , guys we are not in your league at all .

Please keep this in mind when analyzing what we do and our world is a different world , I know some of the things we do might seem funny to you  but  its just like some of the things you guys do look funny to us .

There are  as many of us funny types now a days even in forums like RCG  as your types .

Sai

Sai -I think something is catching up to you   I am not sure why you added my name to this response.  On the other hand, I can see why you added Katty, as he directly suggested going for a branded radio.

If you really read what I wrote, you will realize that all I did is to support this, with the required caution.  And that caution involves two things.

1) Don't do it if you are not the DIY type.  And if you are the non-DIY type, get it done with someone who can handle opening up of radios and soldering on existing PCBs.
2) If you care about your manufacturer warranty, don't do it immediately. Wait for at least the initial warranty to pass.

Now which part do you disagree with ?  Your comments suggest that others may look down on people who are doing this hack, while it is quite the contrary !  If a few people test this and prove this, that will allow 2.4 (yay..  ) to be accessible to even more people, who do not want to invest in a new radio ! 

Time to send you some Valium   

Anwar ,
Sorry I added your name out of habit considering the past few days of our forum activity  .
Deleted now.
Only Katty then.

Hi Sai,

Can you please confirm if the items have been shipped... please let me know the docket number asap. Cant wait for the module... so excited to get it converted

Thanks.
Saurabh

I have also made out schematic diagram will e mail it to you and post it here soon.

The Module is shipped with special instructions for today's delivery will get back to you POD in around 1/2 hour.

Sai

Thanks Sai !!

Would be a good idea if you could also post the video here that you were mentioning yest. It will be a great help for the people who are new / want to convert their Tx into Ghz.


I will be creating a new thread for the conversion with pics once I do the conversion. hope this will help all

Waiting to hear from you on the docet. !!!

Cheers !!!
Saurabh

Here is the schematic of the conversion .
It is actually quite simple to understand :

1) Create an additional negative connection from the Main board of the Tx to the 2.4 G
2) Cut the Positive and the Modulation signal wires going to  the existing Mhz RF Board and route it thru a 6 pole switch to each of the modules .

There you have the Dual Band  switchable Tx.

Sai

Bought it from the UK. No customs charged. As Sai said the one that I bought is for module based TX for your's hack module would fit. I feel hack module is better as you have a convinient switch to change between bands. In module based radios you need to physically change the module to change bands.


I am not sure what you mean by voltage regulator. I assume you are talking about the fat capacitor (orange one). That is used for providing additional power when there is a sudden demand of power from the receiver. You can get those from most electronics spares shop for less than Rs 50.

Looking at the pervious posts (and from other forums) its seems that, this hobby has become more of a buyer and flyer kind of thing... very few wants to experiment. In fact, I do not see a difference between a kid playing with a toy and we playing with our airplanes/helis... This hobby has so much to offer in terms of learning - right from chemistry, physics till aerodynamics... Again its a personal choice and is up to the buyer/flyer/builder to determine what he needs (depending on his appetite for learning and his budget.)  

Whatz the fun if you have everything provided on your table!

This in interesting thread that gives details of many types and makes of  transmitters that have been converted using Assan  Hack Module :
http://www.rcgroups.com/forums/showthread.php?t=994433

Very interesting to read . You will find every known brand of radio  like JR , Futaba , Futaba Robbe , Graupner , Multiplex , Futaba 7CP2.4G  have been converted using Assan hack .

Here is the use of a capacitor for receiver voltage protection

Frankly this kind of went quite fast over my head 

Thank Saju for this info he dug it out .

Sai

Hi Sai,

Did you get to speak to the courier guy Still did not get the package ...

Thanks
Saurabh

Hi Saurabh ,
These are 1 to 1 matters which are not of any interest to anyone else on the forum .
So I would prefer one to one communication  by other channels either PM or SMS or E mail.

I will send you a PM on this .
Sai

Sure thanks

Not quite the right analogy  

One may look at it as Phase 1:  collecting the ingredients and cleaning them, and cutting them in the right shapes and sizes and Phase 2: Cooking them with some amount of skill.   Some people (the "buy and fly" type) want to do only Phase 2.  Sure that also takes skill, and one can spend a life time just doing that and perfecting that.  Others want to spend time in Phase 1, having fun finding alternate ingredients, making sure everything is cut to perfect size etc.

It is not fair equating "flying" to just "eating what has already been cooked".  Plain eating requires little or no skill ;P

Good morning ,

Hello mr.sai i was just wondering if you tested the new hack module ? How was the range approximately ? Any problem with the module ?

kindly let us knw ...

cheers

atul g.

Awesome  

I will give a report later If Saju does not do so by tomorrow evening

Guys just returned from flying 1/2 hour back so any more of RC talk and I could land up with a civil war at Home  so report will have to wait .

I would prefer Saju tells his observations as he was also there.

Flew the Multiplex Easy Cub and Maidened the Multiplex FOX on Assan 2.4 G .

Hi Guys,

I got my Hack module from Sai today. Even I have converted my 72 Mhz Futaba 6EXAP into a Ghz tx. Works great so far. Have not tried on the field as got it done today only. I have also prepared a DETAILED review and guide with pics on how to convert the system. Could not post it as the pics are heavy and only 4 are allowed per post. Also, I have made a pdf doc for the same.

If anyone needs it please PM me, I will mail you on your mail. Its step by step guide with pics... hope you will find it useful. 

Cheers!!!
Saurabh.

You can use http://www.webresizer.com to get each image to manageable size of less than 128kb. Four such images can be attached to each post. If you want to post more than 4 pictures, just "reply" to the same thread thereby creating a new post, to which you can attach another 4 images.

It would be good to have the pictures in this thread instead of people having to bug you with PMs.

Hi Anwar,
Thanks a lot for the link. I have about 15-16 pics... not sure if I will be able to upload... I however have a pdf with me. Just wondering if you can upload if I send you the file. Do let me know your email ID. will send it to you.

Cheers

Saurabh

Since some users may be on slow links, one big PDF document is less preferred than attaching the pictures. Pictures become thumbnails that users can decide whether to download the full version or not. If you are unable to upload, please send the images to the email address on the bottom left.

Hi,
Dint get your email. Can u pls pm or post it here

SAURABH

Look at the green footer of any page, it has the contact email address.

One thing I must admit the plane is far more responsive on 2.4 G .
The controls act faster and the time lag is appreciably reduced.

Like the Easy cub will normally get tossed around a bit in high winds and  so is a bit more difficult to control . Yesterday flying 2.4 G we were able to control it much better .

The capacitor is also really useful as right from the beginning I used to have servo "humming" on the easy cub , the same servo worked without a "hum"  with the assan with the capacitor .

The range was fantastic I could not test it to max but with the easy cub flying at around 350 - 400 ft altitude the control responses were almost instentaneous

Saju could add more.

Anwar though I hate to admit it but 2.4 G gives good confidence especially the speed of control responses
Sai

This may or may not apply in this case, but non-digital servo humming under "no load" conditions typically means that the physical setup is not ideal. This would indicate that the linkage rod is putting undue strain on the servo; possibly due to length or angle issues.

You could be right  see how easily I agree after Assan 2.4 G  .

I had this problem and really did nothing about it , actually I have started taking Multiplex planes for granted .

With no changes to the set up except  the addition of the capacitor and the 2.4 G receiver  how come the " Humming " stopped


Saju explained  yesterday about the Built in BEC  converting power to the motor to 5 V for the receiver and the resultant noise due to the inefficiency of such a system , hence the capacitor  helps by pumping in additional power when the servos need them.

That is why assumed it could be due to the capacitor .
