It seems like fly-by wire is the current buzz term.

And the advantage of the throttle-by wire is??????, in aircraft
applications.

Having been the recipient of a possible throttle jamming incident in the
air, with a linkage that did not give me good feedback of the actual
connection  of the throttle and the throttle body, unless there is a
really good
reason,  other than "that it is available",  in aircraft application, I
think I
 would rather go with the push-pull direct connection variety of control.

Someone please straighten me out

Rich, This is not to "straighten you out" but it's why I'm would like to
at least give it a go at doing this.

Push/Pull direct connection is very nice, particularly when it's to an
engine just up front of you, however sometimes the engine like in my
case is behind you and the cable runs become quite long. I need have to
have 2 throttle controls linked together, it's a Tandem Machine and I
need enough space for people like me - 2 metres tall, 6'6" in the old
measurements.

I really hate having connecting rods on the left side of the seats like
some others have done and the machine is pretty open. If I use a rod
system to join the throttle controls then it sits out in the open, is
easily damaged or tripped over and makes it very hard to get in/out the
left side of the machine, I would really like to able to get in/out the
left side of the machine. So to avoid this issue and I really want to
avoid it, I need use at least one push/pull cable to link the two
throttle levers together so they operate together and then another
cable from one of the throttle controls to the throttle body, now I'm
certainly able to do that and if the electronic control does not work
then I will be doing just that.

However, TK insists that he really wants to test his throttle
controller design. He is also pretty certain that it will be perfectly
reliable, so one must give a fair go after all, I originally asked him
what he thought. He got interested in doing this, it would not be very
fair not to give a fair go. If it works and I have no reason to doubt
that it won't then why not? For others it simply gives another option
for a throttle control system. I'm already completely reliant on all
sorts of other electronics and electrical systems for flying using
an RX-8 Engine, for instance Tracy's EC3, Tracy's EM3, fuel pumps,
trim system etc.

Apart from anything else it is just plain fun to see if it can or will
work without spending too much time or money on it, we've only spent a
couple hours on it so far, I suspect that it will go to a working
prototype with only a very few more hours which is pretty good, it
would more than likely have taken me at least several hours working out
how and where to run the push/pull cables as well as in fabrication time
of a number or brackets and the like and to make sure that it would not
get damaged or bind going to the engine keep water out of the cables etc.
