I have a complete JR radio system that has not been used in about 8 years and I am looking to put it in a Cap 232. How do I make sure that everything will function correctly once in the air? It was in a crash before it was put away and it does not have any damage and appears functional. I put it in an old trainer and taxied around on the ground with it and it had no problems but I'm not sure if there is any more of a thorough check that can be done or should I just by a new receiver? Thanks.

IF the nicads check out good on meter under load test and no glitching with a range check, then you're good to go.
Had you only been flying trainers before you left 8 years ago ?

I was only 13 then and was taking lessons at the time and after the crash I didn't have the money or really the interest to start flying again until recently. I am now taking lessons and I have been assembling a few planes for the future, a 4* 40 for after the trainer and much later down the road the Cap 232. So the Cap 232 will not be my first plane or my second plane. I am going to replace all the NiCads to be safe. Thanks for your help.

Hello!
Well the most important thing to do first is to range check the radio.
All JR and Futaba radios should have at least 100m range with the transmitter antenna fully collapsed. Range in this case means that the servos should work as normal with no servo jidder.
I hope you use a new battery pack, either a welded together 4,8-6V pack or a pack sweat soldered together by yourself. Nicad batteries could be used but better yet is to use Nickel metall hydrid batteries . these cells are available everywhere (GP green cells or Sanyo )and are much better than the "old "Nickel cadmium cells. 2300mAh cells is what I use (both GP and Sanyo) and these cells weight the same as ordinary 500-1100mAh Ni-cad cells but contains much more energy.

just as long as it passes a range check, and the antena is secure, it should be good

100 meters with the antenna collapsed!!! Yikes, I get nothing like that, maybe 50 or so with my JRPROPO X-378 and JR Rx. Batteries are good with plenty of charge, so what`s going wrong?

Thanks for the responses. Is there any disadvantage to going with a 6v battery as opposed to a 4.8v for the Rx?
