I think the question would be better asked this way. Should you splice the antenna wire? IMHO for 5.00 vs. the cost of getting it wrong; have a new wire put on. The length of the wire is critical with each Rx. I accidentally snapped about an inch off my antenna on one of my models. I called Futaba and here is what they told me. The length effects the range distance and the further away you get the range drops exponentially if the wire length is incorrect. If you get this wrong you could have a real problem. Why take the chance for such an inexpensive part? Add to this the potential for additional interference and IMHO it's just not worth the risk. By the way, how are your soldering skills? I don't think this is the item you want to learn on. If you are like me, and your question leads me to believe you are, then you probably don't understand all that you need to know about transmitters and receivers and how they are tuned one to the other. There are guys responding with much experience with this than you and I. I'm all for learning and you have to try things to learn. If you are going to do this I would have someone with experience in the matter do it the first time. My response is not meant as a challenge to guys I respect and have shared post with over time, but more toward your experience level on this subject. Rx. glitches are a bear that can bite you over the simplest things. Then again they work amazingly well when everything is set up properly, tuned and balanced. IMHO I wouldn't take the chance.

I agree 100% with having the Rx tested if crashed. I have a mule airplane I use to test out Rx. even after having them bench tested by the Mfg. I lost one airplane due to a Rx. problem. Maybe this is why I am so careful when it comes to this subject.
