Thanks for your reply

2.row 6 offset 13...however offset cannot be more than 9..so if 13 offset ==9.
I find better base channel with offset=9 for the second transmitter. But the base channel is again not cyclic and some value are omit. Is it normal/possible?

Thanks

Hi all, I've been combing through the code and am wondering what the "IF calibration" refers to. Also there is extensive mention of VCO bank and VCO current, what do these acronyms mean?

Thanks

IF is Intermediate Frequency, it's part of the receiver chain. VCO is Voltage Controlled Oscillator, it provides the frequency for the receiver and transmitter, and is locked to a reference frequency (the crystal, relatively low frequency) via a PLL (Phase Locked Loop).

Hi everyone!

I have the transmitter for the v912 and v913.

Now I'd like to use it as a transmitter for an old RC car I'm restoring and in the future a tricopter I'll build, but also for my v911 and any other wltoys heli I might buy in the future.. I've just started learning arduino and that's what I'll be using on the RC car to give it neat features like obstacle avoidance and yaw stabilisation.

I've read trough this thread a bit but it's all way above my understanding of programming etc so far , so I thought I'd just ask:

Could I use a module like this one combined with an arduino as a receiver for rc cars and multirotors, interpreting the default signal sent by that transmitter?

Likewise could that module, or one like it, in combination with an arduino also control a v911 or the likes e.g. with an xbox controller?
How about a hubsan x4?

Thanks in advance for helping out a noob.

Would it not be cheaper for you to just buy a small turnigy , flysky receiver or one of the wltoys heli/ plane receivers rather than build one?

Now where's the fun in that?

That's like it would be cheaper/easier to let a trained professional fly your RC plane - definitely would eliminate 99% of crashes.

I can relate, as much as I like to build and thinker, sometimes you just don't have the time or motivation to do so, but it doesn't mean you don't want to fly something. So yes sometimes its cheaper to buy.

I'll buy some actuators receivers from this shop : http://www.drcmall.com/shop/shopdeta...T=bmx3Uw%3D%3D because I find they are ideally priced.

I haven't let go my nanorx project, but for the time being I just have to little time to invest, and I prefer having something to fly, it's a lot more relaxing than building and debugging.
