Overview   [Toc] [Top]

Some of the Futaba R/C transmitters have a dedicated slot to insert optional CAMPAC memory modules. These memory modules are available in various capacities, for instance 4 kB, 16 kB, and 64 kB, and enable to store configuration settings for multiple R/C models. A commercial 16 kB Futaba CAMPAC module used to cost about 90 US-$ and provides storage for additional 11 models within the Futaba FC-18V3 plus R/C transmitter.

A fruitful attempt to obtain a more cost-effective CAMPAC-based storage solution has been made with the realization of a CAMPAC clone, i.e., the ClonePac. The ClonePac described below features 1 bank of 16 kB storage, which is accessible without manual bank-switching through a DIP switch, for instance.

Well, the CAMPAC memory module is in fact quite a simple device and it is questionable, whether the exorbitant list price is justified.
So let's build our own parts...

My ClonePacs are based on the work of Jim White, Dave Rigotti, Dave Tatosian, and Rob Crockett. The original ClonePac page used to be located at http://www.geocities.com/CapeCanaveral/Hangar/1071/clonepac.htm, but this URL is no longer valid...

Therefore, here is a local HTML snapshot of Rob Crockett's initial webpage, and a PDF document for print-out.

If you want more than 16 kB of storage, e.g. for your FC-28, you may consider to order Model-Gadget's UltraPAC-II featuring storage of 64 kB (1 bank), 256 kB (4 banks), or 512 kB (8 banks) through the following dealers. In my opinion, the UltraPAC-II is a very nice solution which provides quite a reasonable price-performance ratio regarding engineering- and manufacturing-costs. One UltraPAC item costs between 32 US-$ and 90 US-$.
