[NSRCA-discussion] Chasing glitches (was Lost Abbra)

Tue Aug 8 17:48:32 AKDT 2006

Not a good solution John, but one of the things I've been doing is to iron 
on some small strips of clear Monokote over the edges that are starting to 
lift and I haven't been doing that long enough to be sure if it will last 
any period of time.

>>   The plene:
>>   Quest 3D G2
>>   AXi 4120/18 using Jeti 70 amp ESC
>>   Hitech Supreme 8 RX
>>   4 Blue Bird 621 servos (90 in oz)
>>   2700 mah 4-cell NiCd RX battery (ESC has no BEC function)
>>   2 X 3s 3600 mah LiPo for 6s power (appx 11 to 12 min of Sportsman level
>>Pattern per charge)
>>
>>   Polks Tracker-III TX
>>
>>   I've swapped out every servo (I have 4 spares)
>>   I swapped to a Futaba 127 DF RX and to a Polks Seeker-II and a Seeker 6
>>   Changed the switch harness to an MPI heavy duty with volt indicator.
>>   Changed to a 900 mah 4-cell NiCd for the RX
>>   Tested with and without the volt-watch
>>
>>   Only had one good range check since the problems started with an RX
>>anywhere near the airplane, that was with just the motor and the rudder
>>servo plugged in. (original RX)
>>
>>   Wierd part... the whole radio system works fine if I pull it out of the
>>plane and lay it on the ground similar to how its laid out in the plane.,
>>including the long servo extensions for ailerons and elevator an the motor
>>system. (put it back and the glitching is back)  This is repeatable with
>>any combination of the servos I have.
>>
>>   The other RX's tested all work in the planes they are normally used

>>
>>   TX operates all other planes I have with no issues. (I only use 2
>>frequencies even though I have a few synth RX's and the TX is synthesized)
>>
>>   Current antenna down range check is 50% of my norm, so I don't dare fly
>>it.
>>
