[Plane-O-Joe]

Standard Futaba R-127 that may have a problem. The plane which belongs to my 12 year old son had a busted fuel cell. I pulled the receiver and there was no fuel residue inside the receiver case that I could feel or see. However, the plane will without warning nose up and roll to the right. (I told him he's living right .) An approx. 3 second glitch. I pulled his receiver and replaced it with one of mine. With my receiver and transmitter there is no issue, the plane flys fine. Could this be just a crystal issue? We can send it back to Futaba and pay the approx. $32.00 but I'd rather avoid it if possible. Oh yeah, I could never get the radio to duplicate the glitch on the ground, even with vibration from a sander. :shock:

I had same problem with the exact same kind of rx and it never had any damage -- until it put my plane in the dirt -- (Ok I know its easy to blame something else other than pilot error) I sent mine back and got a new one and never hadthe same problem again

Nitro has an effect on solder...it eats it. If you had a fuel tank rupture, and the rx got soaked then the process has begun. I had some guys tell me that was a myth, but then they put a lump of solder in a jar with some fuel in it, within a couple of days the solder was gone. May work fast, or slow, I don't know. But if you got fuel in a reciever, don't bother sending it in for repair, just trash it and get a replacement.

I have had a filter and a crystal go bad. Both act the same as what you are mentioning. I had a crystal that had been crashed. I always replace a crystal after a crash except this time I did not. It was a light crash. Anyway put it in an Ultra Stick and kept getting glitches. Thought it was the antenna - pulled that outside the fuselage. Flew perfect for one flight then the next one I came down the field pulled vertical full throttle and no control had to just sit back and watch full throttle into asphalt. Either send it in for service and put a new crystal in or trash it.

Jonathan is right. If it sets on there for any time at all it will set up a acidic reaction. If you find it right away. It can be cleaned with isopropyl alcohol, use it as a wipe (I will not tell you to put it in a small spray bottle). javascript:emoticon(':wink:')

Be careful with it. I watched a guy accidentally ignite it with cigarette at his solder station.
