It doesn't work at all, the guy at my LHS said that 9 out of 10 times its the crystal, we will find out when I do the range test with the new crystal.

F-15,
I'm not trying to argue or discredit your LHS, but this isn't true. While it is true that a lot of times it is the crystal in a receiver that causes problems. But it is nowhere near 9 out of 10 times. There are a lot more problems that can and do occur in a receiver after a crash that happens. Cracked circuit boards, damaged electronic components, cracked solder joints, and many other problems can pop up. A range check is not a accurate test of the operation of a receiver that has been involved with a crash. As has been stated earlier in this thread, the only real way to know if your receiver is 100% operable is to send it in and have it serviced by a reputable repair facility. Many times problems with damaged receivers won't show up in a range check, but will show up when subjected to the rigors of flight.

And we are seeing A lot of problems with the 2.4 systems also. They tend to lock up for 4 seconds after signal loss. The loss of signal can be A low battery or just the angle of the antenna of the TX and plane. Now A third and even fourth RX is being offered for the systems for this reason. Nothing is fool proof.
Ken said it all, just send in your crashed gear and have it checked out, it's worth the price to have it done just for the piece of mind.

4 second loss of control just for pointing the antenna in the wrong direction briefly? Thats a pile of balsa for sure. I think I will stick with 72Mhs for a while.

Well, I guess we will have to send it in sometime.

Oh, I just found out that I am using an FM reciever!

72Mhz is an FM frequency.
Some people call PPM receivers FM but the truth is PCM receivers are also FM.

Scratchonly, how do you know it is not the crystal? Did you find a way to check them both, if so let us know how you checked the nonremovable one.

F-15 Fan,

Sorry for your loss. Have you had any training with an instructor? If not, I can understand why you feel the hobby is no fun. It is expensive, a lot more expensive if you don't have any instruction, training, etc. because you will crash more often then if you did have training. Plus, a club and instructor will teach you more than just how to fly. They teach safety, how to tune engines, all about radios, servos, etc.
To find a local club go to the [link=http://www.modelaircraft.org/clubsearch.aspx]AMA Club Search[/link] here: http://www.modelaircraft.org/clubsearch.aspx

Good luck with your Pulse maiden next weekend.

I had an instructor, the only reason I said that was because I just couldn't believe my luck, but I am getting a new FM reciever so I don't risk destroying a second plane.
