receiver reliability
Hi, I fly with a JR 8310 and use a JR 226 FM receiver with 4 of my planes. Just recently I lost a brand new fun tiger because the receiver / radio just quit on me for no reason. However, I don't know if it was because of a glitch or interference. Anyway, I just completed a Katana V2 46 and used the same receiver. First flight was almost the last. The elevator just pulled the bird up vertically at full throttle after take off, but I got it under control and landed right away. I then conducted a range check with the engine running. I walked about 40 paces with the transmitter at arm's length, antenna folded. Not once did I lose control. Can someone help me with this problem? On ground and with the engine running at different speeds, the range was good. However, once in the air, the plane becomes unstable and cannot be trimmed. Any help would be greatly appreciated.

RE: receiver reliability
Hi!
I use JR radios myself and have never since 1980 when JR first came out have had any trouble with them.
Have you checked your batteries, I recommend checking the voltage on each cell (You have either 4 or 5 cells in you package) under load. Easiest way to check is to push needles through the plastic wrapping and use a volt meter. the reading should be 1,25 volt on each cell...lower and you must do something...!
Over here in Europe where we use 35MHz, my JR radios all have a range of 100m with the transmitter antenna fully collapsed, pointing at the airplane and with the receiver antenna inside the airplane fuselage fully extended.
Less than that ...at around 50m and I know something is wrong. This has happened twice for me and all because of bad cells in a battery package.

RE: receiver reliability
could be a bad switch bad battery pack,metal to metal contact.after any unexplained crash or any crash it is best to send the radio back to the manufacturer for a check up,they will make sure it is as new and turn around time is about 2 weeks.time and cost could save future planes.
