I am used to mode 1 :D but this programmable radios are so great stuffs that you can change anything.. Stick positions or even MODE, awesome isnt it?? it is :D

My new 9X is great just awesome, you wont believe but now i can fly my quad very nicely. Atleast i can lift it up the ground with out any glitch :giggle: actually the great control that you have on your radio and its configuration that matters a lot.. Its exactly same as the one you are trying to get from BIMALVED exactly same just name is different FlySky

I see we can easily convert mode1 into mode2. There's spring inside that you need to fix on other side.

Yes, we can convert, but I sorta spoilt my radio doing that.
I was trying to remove the remotely-located spring and broke a small mech. plastic part. Now the yaw stick has no spring and moves freely.
Then I tried to attach the plastic part back (using fevikwik) and tried various springs, but it would be either too strong or too loose, never the same way it was.
So now I disabled yaw on my radio and fly it. :(

btw, I think using mode2 is a little more convenient, since pitch and roll are what require more precision than throttle/yaw. So having roll and pitch on te right hand is better, anyway there are MANY opinions on this...

Yes, exactly the same, but one small differnce. AFAIK, flysky TH-9X has it's antenna ATTACHED to it's module itself, right?
But turnigy 9x has it's antenna and module separately.
I will never be upgrading my module from turnigy to any FRSKY or something and I don't need telemetry, so i preferred turnigy 9x... :)

Ya bro it has antenna attached to its module but does that matters?? i have really no idea what these modules are and how helpful they are..

And yes after knowing that sidewards drift is with throttle even i think mode2 is a little more convenient. Do you know any video where i can find how to convert mode 1 to mode 2???

No, it doesn't matter as long as you don't seriously think of upgrading the module to FrSky or something else.
As someone had answered to your post, module is that part of the transmitter which has all the radio components in it.
Most people (on RCG) buy a turnigy 9x WITHOUT module and buy an FrSky module with telemetry.

You can follow this video to convert mode 1 to mode2 (found in a random search) http://www.youtube.com/watch?v=VmmG9QRKQzI&feature=related

:thumbsup: Any plans to upgrade your 9X's firmware? To TH9X or ER9X? I think you should now be reading http://9xforums.com

satyagupta

Hmmm some alien words for me there.. Now the manual that came along with the radio says this FS-TH9X so does that means that i have TH9X module in it??

BTW this is one that i am using Fly Sky 9 channel 2.4 GHz Transmitter and Receiver

Thanks for the link btw that would help me to know more about the modules and stuff, btw is it important to upgrade it?

No, it's not very important to upgrade. A firmware upgrade just means better menus and more options (which can be more confusing)... Maybe it's better to first get used to the simpler stock firmware and then upgrade to er9x.

rajibcic

hi pls suggest me a frame size to make a quad cop.i will use 750mah motor.

hyd_quads


Adiboy

@rajibcic

Bro its 700 Kv.... which implies rpm/volt.. i.e. at every volt u get 700 rpm rise in the motor...

whereas here "mah" is an abbreviation for battery rating which implies Milli Ampere hour...

rajibcic

ya it should be 750kv.u may say printing mistake. ;D.by the by can u say the optimum size of quad frame

Dharmik

Bro there's no thumb rule about the size of frame. Generally for 750kV motor you will use 10-12inch props, so make sure they don't fight with each-other.
Try 525mm to 600mm

One more tutorial can be found here by Ashta sir

If any correction please let me know. Also if anybody wants to flash ESC i can do it for you without any charge. You just have to pay shipping. At this moment i will able to flash only HK F series ESCs only as pin designed for it.

Nice to see multiwii boards in india. I was using the 'lite' version of it (without baro and mag).
I am now switching to AfroFlight Naze32. ;D

Battery: 3S 4000 mah 20C
ESC: 4 x HK blue series 20A
Motor: DT750
Props: 1047

All i want to know is my battery came along with a bullet connector, now i want to use XT60 connectors in place of that. But this connector will be good upto 60A current, so will this setup be good with XT60 connectors??
