Title: Made in India Radio Controller (Tx Rx) for RC Planes
Post by: garrytan on June 17, 2020, 03:59:36 PM
Hi All,
I am looking for made in India Transmitter and Receiver for RC Plane .
as of now I have built my own using Arduino nano and NRF24L01 and works well.
But is there any Transmitter made in India which could be as good as FlySky Fs-i6 ?


Thanks

I don't think there are any made in India radios. The closest you'd come to one would be RCB OS 10 and RCBi which are manufactured in China but are designed (I think) in India.

@satyagupta sir is it based on opentx or custom is like RCB OS 10.
Could we get ant further details like time, price, features, etc? Looking to replace my non functional RCB6i :)

Cannot do Open TX at the moment may be sometime later. But not now.

There is a long time for it i cannot say anything about it yet.

Really interesting !!! Is it Arduino based ?? The components are all made in India ??

Great to hear all these.

Amid current Indo-China situation, it becomes imperative have most of the things "Made in India". may be little costly or at par with the current ones but having our own country made is the way ahead and a befitting reply to the mass exporters.

The other day I heard of "Made in India" model jet engine in progress and now Tx-Rx too. All of these will be a great leap. I hope all these materialize. Keep us posted. There will be lot of people to test your transmitter.

Although I cannot share technical details at the moment, but yes, everything including electronics, casing, the software has been researched and developed in house by @satyagupta and is manufactured here in India itself.

I was about to buy Flysky FS-i6 but then things got escalate on border . so desided to built my own .
It's simple 4 chanel TX Rx works well . haven't done range test but with some modifications it could be up to 1KM therotically.
Transmitter like these are more than enough for fun flying. Advance feature like Frequency hoping is not needed when not flying with others so it works.
If anyone interested I can share schematic and code .
It's good to see response  for this thread  and good to be part of wonderful community.

Let me be brutally honest! There is nothing like a completely made in India piece of electronics! One may find gadgets assembled locally and reboxed. Unfortunately, China will remain part of the value chain. It is difficult to think of such localisation in 2020. Businesses depend on each other's capability and we're indeed in a global village. The firmware on your radio could be written by somebody in Russia or your radio's cabinet maybe been made on moulding machines using Chinese microchips. One needs to figure out the line where it starts hurting and that is a personal opinion!

My intention is not to kick start an Indo-China debate on the forum but I felt it necessary to spread the awareness.

If your intention instead to make one yourself, a good starting point would be the DIY Mega 2560 on opentx forums or nRF based ones on YouTube. Nontheless, you'd still be using components that came out of a factory in China.

Girish sir, completely is not possible at the moment. But there is always a start :)

The components are from some place in China, if i get a local supplier for components that are originate in India i will move to it. But there is a long time for that to happen. But the design/coding/circuit/model everything is done here :)

Yes it needs to start somewhere (we missed the opportunity decades back), @satya I appreciate what you're doing and it makes me proud to see our brains and capabilities emerging. Totally encouraging and happy to help if required.
 
Just wanted the OP to be aware of what he is looking for. :)

In present scenario radio can be designed/made/assembled in India but most of the components had to be imported. A gradual shift would make things much better which I think will happen in near future.

Most of the electronics has to come from China.
Plastic shell can be procured from Indian manufacturers I think.
Arduino may or may not be choice of developer.

Finally an indigenous tx rx set.


Title: Re: Made in India Radio Controller (Tx Rx) for RC Planes
Post by: asperised on June 22, 2020, 03:24:53 PM
I don't think an Arduino would suffice in today's times where most radios have moved to ARM based chips like STM32.

As you said we need to gradually become better while developing local infrastructure and making products which can be held to an international standard, that is the most likely we can move up the value chain.

Nitesh

 :giggle: :giggle: :giggle: What is your experience in Electronics ? From departure of days of pre 2000, when at least bulk of Thru-Hole Passive and Semiconductor components were actually "Made in India", today in SMD - Microprocessor era, not even SMD Resister are made in India.
So whatever design (not dated) you make for the Transmitter-Receiver,  your device would be anything from 60% to 100% "Made from Chinese Part", and at best "Assembled" in India. No one, I mean absolutely NO one , has a production run of meekest uP like Atmega , leave along Wireless module like Xigbee/Hope RF /NRF/LoRA etc modules.

Made in India Localization for RC Hobby  is a piped dream, with hardly anything more than few people making Airframe (Balsa/EPP/EPO) , few making BLDC motors (UMS Tech Bangalore) and Diesel Engines / tanks (Sharma), Gas Engine (UMS) , in India.

So take it or leave it, the harsh reality is, you just cannot be in this hobby "China Free" ... I am not proponent of China, but telling you the reality.

As Far as "Assembled in India" goes, I have been designing a 433MHz Rx/Tx board with telemetry, based on "Closed" Firmware / Protocol called "Ultimate LRS", for which I designed the PCB and fabricated , but could never build the Tx-Rx ever since the Drone regulations came into picture.
If enough people are interested , I can re-kindle the project. it uses Atmega SSOP Chip, few passive components and Hope RF's RFM23BP 1W module.

Post by: girishsarwal on June 23, 2020, 12:54:45 AM
@ujjwal, that looks a very well designed and a well-packed board!

That was my point indeed, that we've been assembling and reboxing and a lot get passed on with the made in India label. Even indigenously designed chips like the Shakti are a nofab effort. I feel it is important that this state-of-affairs is known, addressed and driven, instead of being hushed up in an effort to make a sale which seemingly has caught up as a trend in recently.

Agree. That is the harsh reality. For the last 3 years I am trying to get turbine wheel casted in Inconel here in India. You know what responses I get?

These are my first hand experience not a tell-tell.

- You approach any Indian company, they won't respond. many times I have turned from the doors only. leave any response from tech people. If by chance some do, the moment they see its a startup , they run like a roadrunner (with bip-bip).
- We don't have capabilities to do such casting (can you believe, what I am asking is simple vacuum wax lost casting to be made). We are in 21st century here and these techniques are 40 years old if not more.
- Bharat forge Indian multinational imports such parts from China...read it again.
- No one is willing to entertain a R&D unless you have really deeeeep pocket. A individual can have a a well-depth but they look for shell-cracking-depth pockets. And thus out you go.


Is this a conducing environment for technologies to develop in-house? No, not at all. Then you turn your head around and see where can you get something which can fit your pocket and budget and there's China knocking the door with small eyes staring at you.
I would rather treat China just as any other country which can actually help you innovate or do R&D. Once you prove your design, then it little easier to get people onboard and turn the keys.

It is us who have made a habit of running for everything that is cheap. like everything.

Yesterday, I was at one hardware shop in an MIDC. wanted to buy a mini file. The shopkeeper showed me 2 files, one Chinese..50 rupees each other one J&K (Indian) 180 rupees each. Now tell me, isn't this reality everywhere.



Title: Re: Made in India Radio Controller (Tx Rx) for RC Planes

Agreed.

Even in local hardware shop. Once I started looking for 3mm plywood. The first question they asked "Ye kisme lagega? (where will you use it?)" By mistake I told "aeromodelling" first they could not understand (which is perfectly ok everybody can not know everything). Then to hide their ignorance they keept mum and showed me the door.

Since then I changed tactics and for push rods, nuts and bolts and plywood .... even foam.... I just say "Beti ke school me craft me lagega? (Its for my daughter for her school's craft class)" and make a very sad face.

It worked...they show me whatever they have and I sometimes find the one that suits most.  :giggle: :giggle:


"New" things or the thought of "new" things makes them very nervous.

So true. I have had the same experience. Sad reality is that India is not conducive for DIY people where any material / infrastructure is needed. Only thing that can be done here without hassles is to develop software as this doesn't need anything but a PC. Very difficult to do anything in the hardware space. The blame lies with both the government policies and the mindset of people. Unfortunately not easy to change either :(

Excellent stuff. i am working on something on the same lines.

From scratch build a radio and also firmware for the same. its using following components

STM23F105
NRF24+ module (for cheap) and CC2500 module which will be little expensive
Both have PA+LNA


We are in stage for designing a 3D model for the same. Once its done will put it to test among the community.

Hi Satyagupta,
Awesome, I'm eagerly waiting for your transmitter.
I had pretty bad experience with Fake nRF24L01+ and ESB in production for a different project.
I'm on a quest to build a completely Indian made drone except for motors batteries and props.
Let me know if you need extra pair of hands on your project.

I wanted to start with CC2500 but I couldn't find any reliable resources to link it with stm32 (library I mean).

Also I have worked with Arduino, which is very easy to code. But on my one of my friend's insistence I decided to use arm mcu (stm32) which is totally new for me . Hence wanted to use libraries which are already available for ready to use.


Title: Re: Made in India Radio Controller (Tx Rx) for RC Planes
Post by: RCChennai on August 14, 2020, 08:48:36 PM
cc2500 libraries are available for c51 in the product page i'm modifying them to use with HAL Stm32. I have been using stm32 for the past few years and they are very easy to program and setup especially with the new STM32CubeIDE

Nice will start working on my ms2k radio encoder soon. More interested in diy multi module and frsky rx for micro rc stuff.

In your radio build after the MCU reads the Analog/Digital data before ppm signal is output, the settings and stuff will happen in phone and then sent to MCU after which ppm signal is constructed?


Title: Re: Made in India Radio Controller (Tx Rx) for RC Planes
Post by: RCChennai on August 19, 2020, 03:12:26 PM
after the config is sent from the phone it will be written in emulated eeprom of stm32 then the global variables will be updated. Timer interrupt with  priority zero will be used to construct the PPM frame and all analog read and sending data to Bluetooth will occur in sync time in the PPM frame.

Title: Re: Made in India Radio Controller (Tx Rx) for RC Planes
Post by: RCChennai on August 19, 2020, 07:50:08 PM
all the trims and channel mixing  will come under profile. Transmitter will have buttons to cycle through profiles and there will be 4 LEDs (binary encoded) up to to 16 profiles can be stored and can be modified on the fly using Bluetooth app

I hand soldered it with hot air station. I confirmed that the chips are soldered by using my microscope. I have to change the antenna. I don't have enough space to test the full range. If anyone is interested in testing the module I can send them one if they can test the range.

Hello Indian RC Pilots,
Filling great to announcing all.
We  are here in the india as a first ever Indian Radio Control Company.
 "www.rcairfield.com".
As a manufacturer in RC, we started with airplane with full RTF kit and PNP kits which are totally made in India.
And in response with RC community in India, we are soon manufacturing other RC goods like ESC, Flight controllers, multi channel all in one radios for Indoor/ Outdoor aircrafts and Multirotos.
