I have bought a Hobbico Accu Cycle Tx/Rx battery cycler.It has a 15 hour timer built into it after that it goes into a trickle charge mode that according to the booklet the batteries can be left on.My question is the charger will supply an 1875 mah charge in 15 hours I can't find cells rated for 1875.1800 or 2000 these are going to be used in a DX7 I want the mahr to match on both the RX and TX packs due to my understanding of how the charger works.Also I will be changing the rx pack from NiCd to NiMh.Is this the most economical way to go?

I love the smell of nitro in the morning..

I don,t own an Accu cycle, but by reading at the manual :

http://manuals.hobbico.com/hca/hcap0260-manual.pdf

It seams that the discharge/charge process is automatic. The 15 hours delay is only a safety :

Quote 
The Accu-Cycle uses an internal timer to automatically switch from a constant charge rate over to trickle charge after 15 hours.
The Accu-Cycle automatically terminates discharge when your battery voltage drops to a predetermined value. After
discharge is complete, the Accu-Cycle will automatically switch back to the charge mode, recharging your batteries so they
are ready for use. Your battery’s discharge data will remain on the display after discharge is complete for your convenience.

As for going NimH on the receiver side, be aware that some nimh pack have higher internal resistance than nicad pack. This leads to a lower capacity of giving "juice/amps" when the model requires.

Don't put AA NIMH sized cells on your model. SubC size, probably something at least 2400 or 3000+ mAh would be required.

It also depends on the type of flight you are doing. If it's quite soft, you won't notice any problem with NIMH. Just be sure your batteries are able to handle the load

Have fun!
