Hello

First off - I am new to quadcopter flying - so please be patient with me

I own a Turnigy Evolution. I bought it mainly for practicing in the simulator. But i like the formfactor and i would like to fly my quads with it (and i dont have another transmitter).
A few days ago i bought a Blade Torrent 110 - i knew i would need to change the receiver on this to fly it with the Evolution. I thought this would be easy, just soldering the wires from the new Receiver (Turnigy FS-A8S 2.4Ghz 8CH mini Receiver) to the same spots on the flightcontroller as the stock one is wired up. But it seems it is not that simple! 
Problem is that there is not even the same amount of wires.. :/ i saw a few tutorials for installing the FS-A8S but there were always UART spots on the flightcontroller. On the Blade Torrent FC there is only this RX marked white thingy.. im a little bit stuck right now.. here a picture of the setup:
Blade Torrent Setup

Can someone tell me if this is even possible to do? or does this flightcontroller not support this kind of receiver? It also seems that the A8S receiver does not have to be soldered to the power board? Plese help me.

Kind regards
David

This is a spectrum satellite RX, remove all connections from the FC and PDB/ESC. It has more wires just because apart from FC satellite port it is also connected straight into the battery power.

What you need for a8s is just three wires:
white signal to RX2 (or a dedicated PPM/SBUS/IBUS pad if one is present)
black to gnd on FC
red to +5V on FC

Go to ports tab and enable serialRX on UART that is bound to this port - maybe you'll have to try other UARTs since I don't know the layout of this board. Be careful here since UART1 may be also used by your USB port - in this case, try other
Go to configuration and enable SerialRX and choose IBUS

Test in receiver tab with props off, battery connected

A8S power specs are the same as this Spectrum satellite RX, you can try powering it from the same red wire. I have never tried that though - I have always tapped into FCs 5V to power it.

Wow! Thx for the fast replys.  Im at work right now and i will give it a try. Hopefully i find some time before the weekend.
I will update you guys if i was able to successfully change the receiver. Looking forward to fly this little bastard 

No biggie, if you want, you may post photos of the mod in http://intofpv.com/forum-tutorials-hacks-and-how-to
Maybe other people will find this helpful

Ok just to make it clear i made the following picture of the FC and labeled it with different numbers: Picture

So I connect the white wire to RX2 - Nr. 1 on Picture


And then the black wire to GND - but which one is it? Nr. 2 or Nr. 3?

And for the red wire to +5v I take Nr. 4 or 5? Or even another one? 

I already took off the stock reveiver. I was not able to remove this black rubber stuff which protects the soldering points, but i cut it off at the bottom as shown in this Picture: Picture
Do you think thats gonna be a problem since I didnt solder it off properly?

Just make sure the cut wires can't touch anything when reassembled and should be fine (if you have liquid insulating tape use that - or cover with electrical tape).

The power requirements are the same as the spektrum Rx you removed (4-8.4 volts).  I think I would try attaching the red, black, white wires to the exact same place the red, black, gray wires were on the spektrum (socket marked rx).  Cut the pigtail from the spektrum and splice the plug to the 3-wire harness of A8S (you won't need the yellow wire).  You'll need to select SBUS (or iBUS) on the new receiver (I think it mentions in the manual how).

If you do this, you would use the same UART as is already configured in Betaflight (no changes in the Ports tab, I think) - but then you'd have to change the serial provider (in the configuration tab) from Spektrum to match what you selected above (SBUS or IBUS).

EDIT: I'm not sure that the pin spacing is different on those plugs or if the connectors use the same type of pins, but you might check. If the pins are the same, you might be able to lift the little tabs on the spektrum plug, remove the wires, and plug them into the A8S plug. (That would be easier than splicing.)

Ok. I was able to solder the receiver to the FC. After a kind of weird bind process i was able to set it up and checked the receiver tab in beta flight. Everything looked good as far. i moved the sticks and i could see the reaction in the receiver tab. I built everything together and wanted to do a test without props on. I turned on the Evolution and connected the Torrent to the battery. I moved the throttle up but nothing happened. So i disconnected the Torrent from the battery and connected it via USB to the PC. Again looked at Betaflight on receiver tab. And now the throttle seems to be jumping up and down even if i do not touch the sticks. so does the yaw but in a smaller area. When i move the sticks i see there is a signal but its kind of cut off. Throttle goes up und jumps straight back to bottom.
Any idee whats wrong here?

Thx for your help

Check the channel order - I don't think they are the same for Spektrum and FlySky.

Sadly i was not able yet to make it run. I checked the channel mapping. According to some guides i saw about the turnigy evolution the channel map needs to be set to AETR1234 which i did.

After the problems i had with the jumping throttle and yaw i de- and resoldered the receiver to the flightcontroller. Thought it could be a problem with bad soldering since im not very used to soldering but i never got back to the point where the receiver gets a signal from the Turnigy Evolution. I cant even get the receiver into bind mode. Once i power up the flightcontroller over USB while the receiver is connected, the LED on the receiver blinks a few times (maybe 4 seconds) and then nothing else happens. 

According to some videos i saw the receiver should blink continuously when there is no connection to the receiver. As soon the receiver is connected to the transmitter the LED should show a stable red. I was never at this point, not even when i got signal from the evolution. 

Here some pictures of the soldered receiver: RX2 / 5V/GND

I know its not the nicest soldering work   the small pieces around the soldering points are from the desoldering pump. At least i did not damage the FC yet and im still able to connect it over betaflight.

Again.. any idee what to try next?

PS: i ordered a multimeter to check the voltage which goes to the receiver and a 2nd FS-A8S receiver.. just in case i got a bad one. But this takes about 2 to 3 weeks to arrive and i really want to fly this thing. And i wrote an email tho horizon product support to get the manual of the Spektrum SPMFCMF300 flightcontroller since they dont have it on their website.

So thx for your help and advices in advance
