I show you the pitot tube I use on my Top Flite Taurus. This is needed for real (air)speed control and data logging.

Sorry . . I am ignorant. How does this work ?? (within the rules . . )
If it is to electronically control the engine revs for constant flight speed . . how will it maintain this constant speed in a vertical down line with the throttle off ? Doesn't gravity, air density and airframe drag control the speed in this condition ??
Controlling the ''appearance'' of constant speed flying F3A is relatively easy . . we have a throttle stick
. It's the manoeuvres that give us trouble
. As for the constant speed on vertical down lines . . I believe it is really about motor and prop choices, AND induced drag designed into the airframe. Mike might be able to help you with the airframe design here
I guess it's kind of similar to Formula 1 car racing. They change the rules, and engineers design new cars to operate as efficiently as possible within the new rules . . in F3A, they create new manoeuvres and pattern/aerobatic schedules. Often, a plane used competitively for schedules in ''days gone by'' will not fly some manoeuvres in the new schedules as well as it should, requiring modifications to the airframe. The latest appearance of F3A planes is a DIRECT result of airframe design meeting the requirements of these newer schedules, with increasingly complex manoeuvres involving integrated rolls in loops and circles, Knife edge snaps, etc., etc. . . none of which were flown (as far as I know) when the Taurus was competing. Hence . . the Taurus will NOT compete in F3A today ! . . not a chance . . even WITH a Pitot Tube. Sorry, Cees.

In my own tread and the Ed Kazmirski’s Taurus thread, I did spend some time in several posts about this subject. Also combined with contra rotating propellers.
But first read this, about the way I experience your way of communicating with me, it is like:
Anthony Fokker uses one of his gun synchronizing systems to shoot through the surface of the rotating propeller. He did mount it on an old fighter to research
Now he is chatting with the American pilots after a joke about a blimp, after he is forced to show them the system so they believe he knows something about airplanes and wasn’t “trolling”.
He is surprised by the way they react, because they telling everyone now, he did want to prove he could beat their modern SPADs and Camels with his (100 years?) old plane.
He says, “No gents, invitation ignored, if that was my goal, then I did not show you anything, did not argue about anything and only you would have meet one of my pilots above the battlefield!”
They also do offer him help of their designer to build a better plane!!
. . I believe it is really about motor and prop choices,
Yes Jeff, so you do not destroy them with your own gun when you hit them.
Also interesting to read post

And Jeff, do you want to know these posts in the other threads, because answerring your question n this thread would be off topic?
