Futaba Programming Sheets
Model aircraft transmitters with up to 20 model memories are fine, but what happens if you loose the stored data ? There is no back up copy and re-entering the data, even if you knew what it was, could take hours, with no guarantee of success. What about when you buy a new Tx. Most of the data is entered on a trial and error basis until you find a set of parameters that work well. Repeating these entries exactly may be almost impossible, at the best it will take time. Doing it at the flying field under pressure is virtually impossible. To avoid most of these problems I have produced (largely for my own use) a set of Data Sheets that I have placed on my website. This gives me the ability to recall these setting almost anywhere in the known universe. In the event of data loss, or to use a new or borrowed TX the data can be downloaded and re-entered with the confidence that it will be accurate. It is of course important to keep the data up to date. I hope you will find the basic idea of some value and trust you may never need to use them. I have come across a much more sophisticated system for the Futaba 9C and a link is given below. Use the Sub Trim to set all trims to Zero on the Tx Display. Using Sub Trim ensures you never loose your Trim Settings. Keep up to date. You may think this is a waste of time, a friend recently lost his Tx following a freak accident. Re-programming his new Tx with 20 models was a nightmare. Some modern Tx's have a USB link to a PC so you can upload/download at will. This gives a virtually unlimited model memory and another excuse for a crash !!
Using the Sub Trim Function. In pre electronic times, after a few test flight the servo/control links were adjusted to give the required settings with the trim levers SET TO NEUTRAL. This mechanical adjustment can now be done electronically using the Sub Trim function. If we assume that the Rudder needs a couple of degrees left, center the Tx trim to Neutral, open up the Sub Trim function and re adjust the Rudder using Sub Trim to give the required couple of degrees offset. You can now fly with the Tx (external) trim set to Neutral but the internal Sub Trim will always give you the Rudder Offset required in the Tx memory. In this way you never need to remember any trim settings.
Note there is a "Hidden Menu" on the Futaba T7CP that will set MODE & other parameters such as Language, 1,2,3,4. This menu is NOT in the manual.
Note The Zagi Setup (9) can be used for any Delta or Flying Wing model requiring an Elevon configuration. (Elevator/Aileron)
