Great to see the auto-trim. Hope the "positive news" is that all hurdles are behind us and the "release" is eminent.

That is not true DirtyBird, I saw it and felt it. Jim has been flying with it under testing conditions that other companies just let the RC community (us) buy it before the bugs have been tested out.

I am in the programming businesses, and I agree a company must do every effort to avoid Bugs on the software and normally they do, BUT no company (or team) can account for every possible scenario so always Bugs will be there no matter what, The final debug phase is when many users start to use the system and that will happens when the unit hit the market.

Many examples of what I say exist Iphone, windows etc etc etc the list could be endless.

In the same taking , I company or a team have to define GOALS and target days to finish a project.

Correct... the transmitter certainly exists. We have shown it at various trade shows like Toledo model expo and the AMA show. People have held it, twiddled the sticks, listened to speech generated by it, seen the display and menus, etc.

Please keep this thread reserved for questions pertaining to the transmitter's specifications.

I can see Pat's point. I too see trims as a stick "thing." When I trim elevons or V-tails it is aways a bit confusing on the servo end... i.e. left aileron is also up elevator.

However I guess the bottom line is that the auto trim (stick or servo) will quickly get you flying in a stable trim. Then as per usual you land, center the servo arms, tweak the linkages, re-launch, re-trim, etc.

It seems that most people don't mechanically match servo linkages anymore. In fact, I would guess that the vast majority of people in the hobby would have no idea what that really is. Back in the day, we didn't have digital trims and model memories, so we tried to setup our models so that the trims were always neutral. We always had to do a bit of trimming for each aircraft, but at least it would not be extreme.

What do the control linkages have to do with the transmitter specifications?
Stick to the subject ,Jim.
The transmitter specification most people would like to see is its release date.

well, never had problems matching the crank of the torque rod from the escapement to the loop wire under the rudder. All that changed when the idiots
introduced rotary output and control horns that now have to match the hinge line
to exclude differential. give me 300 turns on the escapement drive rubber band any day.

techie talk!

"300 turns on the escapement drive rubber band"

Now you are talking techie stuff! I built and added a galloping ghost control box to my Orbit TX back in the 1900s. Worked great... wish I still had that combo to fly again.

I remember seeing the Tucker (Car)on display but we couldn't take a check ride. It had no transmission.
Did this transmitter have a circuit board in it?

Jim,

Wouldn't it be easier to just trim out the plane, then when you press the auto-trim switch, it just writes whatever is in the trim to the subtrim and then zeroes out the trims? This way, you don't need to do hand calistenics and worry about whether you need to release the switch or the sticks first. As someone (was it you?) said, doing the the thing in the wrong sequence will make the matter worse, the way you have it.

I view Jim's method as trimming ONE stick at a time.... ie, elevator........make the adjustment and then aileron and make the adjustment.....

I see your point, though.... it would be nearly impossible to do both at the same time.....

I've always "trimmed in flight" and then after the test flight, re-adjust the rods to zero out the trims.....

Please read the earlier posts. We have been discussing the transmitter's auto-trim feature. I stated that how the auto-trim affects the sub-trim functions, not the trim functions. I referenced previous transmitter designs that required manual adjustments of the control rods and/or servo arms to achieve neutral trims.
