[NSRCA-discussion] Futaba and pattern

[Del K. Rykert]

If they truly care they should listen to Don's last comment.. Is one reason I flatly refuse still to use any Futoyba stuff.. 
 
When they screwed my best friend and made him lose 3 airplanes in two days because of their equipment we both swore we would never sue their stuff again.. An we both haven't.. and have encouraged our friends to buy anything but..  When they don't care and don't want to accept responsibility for their problems it leaves a bitter taste that last a life time for some of us. 
 
    For those that are dying to know..  The one day both radios has just come back from a fresh tune up at the factory..  The first flight with both of those radios rekitted both planes and both radios had worked flawlessly before being sent in for tweaking.. The next day I had the transmitter stick fall out of elevator gimbals when it was up stairs..  trying flying with trim when it is going vertical let alone losing site of stick in tall grass. Friends found it after it crashed..  Radio had never been dropped while in my possession.. I would like to believe people in impound also treated with the same love I always did. 
 
Pilots that expand great amounts of time or money to create and fly maybe remember and don't forgive & forget as others might..  I am definitely in that group.

  I would add the following to the list and expand on Jim's thoughts below......
  Let us run 2 or 3 lipos as the airborne battery and let us pick the voltage we want to go into Battery Failsafe.  I would like a servo like the 9650 but with a tighter gear train.  Also, get rid of the feedback pots like Jim mentions below.  Either go to a stepper motor approach or go to an optical feedback instead of the mechanical wipers that wear out over time and centering goes away.  I know that would impact the repair/replacement revenue but give us something we can run until some unfortunate collision with the ground.

  My last wish if for Futaba to be more straight forward in their communications with customers as to what is actually going on.  The delays in the 2.4G systems and modules is frustrating even tho I am willing to wait for the 'right' system.  Also, if there are issues with a system, TELL US!!!  We pay a lot of money for these radio systems and pattern planes and if those systems have a problem (like the long antennas on the 5014), tell us the truth so we can choose what to do instead of basically denying anything is wrong.  The lack of accurate and timely information irritated me much more than the fact there were some issues.

    My first thought won't make everyone happy because it will make a lot  
    of stuff obsolete but I think it is time to get rid of the analog  
    pulse width interface between the receiver and servos.  It is time for  
    a high speed computer bus so more information could be transferred at  
    a higher rate.  The servo should use a brushless motor and if possible  
    a stepper motor that would eliminate the need for a feedback pot.  In  
    other words a true digital servo.  It should run with a range of  
    voltages (7.2 to 9.0 volts) with no change in performance so no  
    voltage regulators would be required.  It should keep working, at a  
    noticeably slower rate,  from 7.2 down to 3.6 volts.  It should be  
    programmable so servos could be matched exactly at all positions.
