I modified my hitec 555 receiver. I did not want to use a y cable to run my ailerons so I could use mixing. I have a hitec eclispe 7 ch radio with the spectra module. With the radio ch 5 for the 555 is used as the retract ch and I tried to mix it with the other ailerons ch but no matter what I tried I could not get it to work.

My friend and I found a schematic on the 535 receiver and it showed how to break out the ch 6, 7 and 8. We went ahead and solder a wire on the 555 so now we have ch 6 so we can have separate ailerons so we can do mixing. I have another post asking if you can mix ch 5 with ailerons and people said it can be done but it won't work with my radio well at least I can't get it to work so we went ahead and broke out ch 6 and it works perfect.

We did it to my 555 and 2 of my friends that are building mini's. It's so easy to do it takes less then 5 min to do. We cut up a y cable we had and took one end and solder it onto the 555 its so easy and works perfect. If people want me to post a pic of it let me know I do not have the camera right now but I will have it later. If you want to do this mod I will post a pic and you can see how easy it is to do.

Post it....

Ok here it is, IF YOU TRY THIS AND IT DOES NOT WORK DON'T BLAME ME TRY IT AT YOUR OWN RISK. Now that I said that it is really easy takes like 5 min or less. Ok to get ch 6 on your hitec 555 take a look at the pics below and solder a wire that your servos will plug into on the locations you can see in the pic.

You can the see neg wire the black one can go anywhere on the out side the whole out side in neg, and the red goes beside that whole strip is pos. The signal wire the white one goes on the pin as you can see in the pic that will give you ch 6. On that black chip in the upper right hand corner in the pic you can see a dot that is pin one do not solder on that side solder on the side as you see in the pic 5 pins over from the right. Be careful to solder it in the right spot check 3 times and solder once

Then all you have to do is melt or cut a spot in your case to bring the new wire out through and your set. If you see that the wires may touch a sharp pin you can put a thin piece of paper or cardboard under the wire on the board.

Thats it anyone that does this let me know how you like it.

No one has tried this mod yet?

Hi Brian: I am flying an ION Warmmaster Sailplane with the 555 receiver and I want to add speed brakes. I have tried without success. Your modification to the receiver is the answer I have been looking for. Thanks for posting. Will give it a try sometime soon.

I just did it works
thanks

Do you have a link for this? Or can you send the file? For the schematic itself?
