Before a single $ need be spent. Consider this. Swap the Rx of the two plane in question (right, swap them and not just replace them). Disconnect all servos and redo them one at a time. Cut off section of the Rx antenna to a length equal to the metal push rods. Electrically connect remaining antenna wire to the metal push rods, nearer to the servo output. Electrically insulate the metal gear servo output shaft from the metal push rods. that prevent spurious phase modulation to the in coming signal. If there is more than one metal push rod, electrically common all starting end points to the shortened Rx antenna. Any moving metal link must be alternately insulated. if there are 4 metal gears, make alternate nylon gear, or rap servo with tin foil. if there are three metal parts, servo arm-metal rod-metal horn..etc. alternate them with nylon replacements. Use tin foil to rap Volz servo and connect servo -ve chassis to foil rap. that prevent spurious phase modulation by the metal gears. Do ground range test to verify. Good luck YK Chan Seattle area.

The successful E2V's are using Futaba PCM Rx's (mine's an older single conversion, I think Dave's is dual conversion) and Futaba/JR/Airtronic servos. The problematic E3 installations are Futaba dual conversion FM Rx's and Volz Micro-Maxx servos. >> RCSE-List facilities provided by Model Airplane News.
