That is the whole point - you do not have to buy
a transmitter - just buy the module (size of a matchbox)
and fit to your existing transmitter

thanks a lot for this info Saikat, i really never heard of this thing before...
Im good at soldering even with SMD level and designed more than 100 embedded boards at least,
any guide or any website would be helpful.?

9 gm servo from avionic
2024 micro brushless motor avionic
1500 mah 7.4 v lipo

my post could be very funny for everyone but i am in a situation :giggle: :giggle: :giggle:
now a day i read a lot and i had seen lots of youtube ...

i had spent some money second time for tx /rx and i can't take it lightly as i have only one set of receiver of futaba and

i had blown up the avionic receiver at the date of arrival or it could be faulty circuit,
now i lost all hope of getting receiver from rc bazaar.
and i was  in need of complete set for more then one month (tx/rx) from which i can continue my project ..

i know that lipo can power receiver by esc but i need experts to suggest which lipo and which esc to use  please understand my situation this is second time with  lots of investment

thats why i write this post.

Good job Wingman,

You dont need a seperate receiver battery if you are going for a electric setup, the BEC in the ESC will do the job.

a few steps you could consider.
First determine your AUW(the total expected weight of the plane including the battery)
Then select your motor prop ESC setup accordingly
any receiver with a BEC can power up the receiver and you should not connect the RX directly to LIPO and this may burn it.

This video could give you an idea about ESC LIPO motor setup
http://www.rcindia.org/beginners-zone/ths-video-tutorials-on-youtube/msg148816/#msg148816

in this video substitute the servo tester with a RX.
Above all DO NOT connect anything if you are unsure of it. Futaba is a good piece of reliable hardware(Costly too) and should work fine. Please take the help of a nearby club. they will be very glad to help you with setting up the power train.

@wingmanbunty...
just a suggestion... while making pencil sketches of airplanes, make the lines crisp and sharp... i see that at couple of places you have done overwriting of some lines... it spoils the artwork.. what i suugest is that make a rough sketch first on a rough paper and then race it onto a butterpaper.
then use that to make the final sketch with neat lines and strokes

i have learnt this by experience( grew up drawing jets) this is professional advice given to me by my sketching tutor at school when i was 12. remembered it till no and using it till date

@topalle

       very nice to get drawing tips from professional like you. thanks sir i will take care next time.

but sir as from child i do not use butter paper or carbon paper to improve my drawing . i used to draw using boll pen . even i draw from pencil i do not use rubber to rub and give finishing . that is my style once a line is drawing i try to improve or hide it any way , once the line is drown it is final.

              but i will take your tip and try to improve my drawing.
i would like to see any of your drawing what colours r u using.
if possible pls post it.

Dear Wingmanbunty,
Well your josh seems to be great towards making and flying aeromodels.  Well I am now expert... but what I can tell you is before trying to jump into making your own designed models of aeroplanes you would do well by making models of drawings already present in various forums / weblinks of trainer model aeromodels.  This will ensure that you have the right proportions and the required shape.  Anything and everything does not fly.  Also read something about aerodynamics.... like lift & drag, weight & balance in flight..... these issues will go a long way in ensuring that you do not run out of good knowledge and correct advice on this hobby.  Many, in fact many have given up because they thought anything and everything can fly.........
Happy flying.
Well I been into aeromodelling since I was in School....  and then been in the air for over 30 years.  Now looking to be back into aeromodelling full time...

@shobhit17

                This bug is inside me as from child, lift, drag, weight ratio can not kill my hobby the only thing killing me now a days that I pay money and I do not get the right stuff to build airplane, I spend near about 19000 rs and still I do not have reliable equipment to build new type of airplane I still use my 10 years old equipment when I was student.

              Knowledge is everything sir u r right, lots of people leave this hobby it is also right, but the thing is how many people are there having good knowledge and share it with beginner in the positive direction or give assistance in nice way.
                                 
                        Making this hobby limited to a group of people , and if a beginner want some assistance in building a first airplane or want fly fist time , not showing the right assistance is the fact of this hobby

That's why people leave this hobby .....

Now a day lots of people get start, because a model cost near about 25000 rs investment and one mistake blow up everything. And this mistake ruined all hopes
It is killer of hobby


This is the time where expert assistance is needed and chances of failure will be very less

Dear Wingmanbunty,
Do not be disheartened.....  It appears to be the same case as it was for me many many many years ago.... I made my firsl tow like glider when I was in 5th standard in the early 1980's.... Best of luck.. if you need any assistance maybe I can be of some help....
Happy Landings
