Default What does FG, C, Z mean in Futaba spec?

A response from Futaba to the question:

I have been a huge Futaba fan for many years and have never understood the scheme used in the radio designations such as the 7C versus the 8FG.
Letters like C, FG, Z and others are confusing when you don't understand how they are used as identifiers and corresponding performance.

"Thank you for your recent e-mail.
They are just a part of the model number and do not mean anything.
Should you have any further questions or concerns, please do not hesitate to contact us at this email address. (Please be sure to copy all previous emails into any future questions.)
DID YOU KNOW that our web pages now all contain FAQs? (Frequently asked questions) Please drop by and take a look! We hope you'll find the information helpful and valuable to you."

Well at least the 6, 7 and 9 tell you something . And also you could work out what the receivers were:

R for receiver, D for Dual Conversion with F for PPM and P for PCM.

R114F - PPM single conversion, R148DP PCM dual conversion etc.

Smile Futaba's Secret Code for Model Numbers

I would think there would be more information to the end users regarding the letters used in the transmitter model numbers. Thanks for the input on the receivers.....

Often the Designation has included either an A or H for airplane or Helicopter.

Futaba 9CA or 9CH for example

Also they used to include an F or a P to indicate if the package came with an FM/PPM receiver or an FM/PCM receiver so you would have:

9CAF or 9CAP or 9CHF or 9CHP.

All had the same software. The Heli versions have/had slightly different switch positions and would default to heli. They also had smooth throttle sticks as opposed to the rachet throttle on the airplane versions. Other than that they were the same.

Before retiring, our control model numbers where I worked had little or no relation as to what they did. Many times, those model number codes were decided by the people in the marketing group.

As for Futaba, don't understand this information:
http://2.4gigahertz.com/features/receiver-tips.html

Apparently everything in this temperature issue is dated before 2008. It appears to be a Futaba web page.

Question, was this ever a problem? And, if so, has Futaba resolved it?

Futaba FAQ : Radio System Feature Comparison
The numbers do have a purpose as far as the designers are concerned.
Users will note those with current "F" designation are Fully upgradeable by user and have provision for expansion whereas the older "C" can be considered Constants - user had to buy a new TX to acquire the improved versions.
Both 8FG & 10C are actually only 8+2ch, but the 8FG provides for future increases. An interesting thread

Good logic to go with 8FG if considering a 10C. Better resolution and easier firmware upgrades.
