Matt.. I had a guy come in to the shop the other day with the same problem. He also had the 2343 servo. We hooked a capacitor to the 3rd channel on the reciever and it worked fine.

What speedo do you run? I read somewhere that some people have had problems with LRP's, something to do with the output voltage or something, i dont know for sure. Thats what the customer I helped had... his worked fine with the capacitor though.

Let me know if you figure anything out.
