Hi, I'm new to the forum so thank you for accepting me..

I have been flying RC for many years but never experienced the following....

Some years ago I was given a second hand 9C Super radio but have only just got around to looking at it!!!

I bought a new Nimh battery for it 9.6V 2500 mAh, which I fully charged and installed correctly in the transmitter.

Unfortunately, on turning on the Tx to set up a model, the battery drained at an alarming rate and was down to 8V in under 4 minutes!!!

Has anyone experienced this or have any ideas please??

Thanks a lot

I would cycle the battery to see if it is holding the proper capacity. Also if this operating on 72 mhz you should always extend the ant at least halfway when the transmitter is turned on to avoid the RF output board overheating.

Apparent lack of capacity isn't unusual with a NiMh battery until they are cycled a few times.

Always a good idea to do a forming charge as noted above. Charge the pack and cycle down to 1.1 volts per cell. Then charge again. After a couple of time doing that it should act normally.

Quick reminder, this is not an open discussion forum. I do my best to answer as quickly as I can, but sometimes it may take a few hours.

Thanks.
