[NSRCA-discussion] interference

I've used / recommend the throttle return spring on heli's - usually saves some parts from full throttle bashing after a crash.

  I have thought about using a small spring on throttle, such that if the servo loses power the spring will pull the throttle back to idle. Of course, this will only work with a coreless motor servo, and the spring will cause the servo to draw current when it normally would not, but I think the advantage is obvious.

    Well, assuming you had your failsafe set to kill throttle it sounds like you're probably correct that you had a power failure of some sort on the RX side.

    Sorry to hear that.

      Keith,  No need to have used a hammer on that RX it was obliterated when I scooped the two garbage bags full of debris.  I immediately sent the JR 10X to Tony and ordered a dual conversion RX w/ full explanation of the event.  Jaccio switch, parsons clips and a two year old Duralite battery.  Not glitch before the crash.  It acted like a battery died.  Went into first loop of Cuban eight.  Loop opened up (blowback) slow rolled over and dove in.  No control on sticks, throttle stayed where it was at beginning of maneuver.  THX Jerry

      Jerry,
       
      I've personally had no problem with steel pull-pull cables, however, I've also been careful to keep the antenna away from the pull-pull cables by several inches.
       
      Do you understand what occurred with your last incident?  I've heard of people losing  their replacement plane because they didn't realize they had either a bad TX or bad RX and they used them in the replacement plane. Therefore, if I were you I'd focus on making 100% SURE that none of the components used before (that you plan to use again, including TX) are faulty. 
       
      I'm not quite this hard core, but Earl Haury once told me that when he has a crash he takes the RX home and introduces it to his hammer. This would certainly prevent any problems with the RX (either causing the crash or caused by the crash) from downing any future planes.

        In an effort to avoid turning my new pattern ship into a dirt seeking comet similar to my last Oly, I've been researching some possible causes,  I recently read from one source that one would or could have interference problems if when using steel pull-pull cables and installing the antenna parallel to them inside the fuse.  I have seen a number of AC at contests w/this configuration that seem to have no interference problems.  Your  experience, thoughts please.  THX - Jerry
