Futaba tx/JR servos, need help!!!!
Hey guys, need help!!!

Have a Bandit that my Futaba 5101 discontinued servos started acting funny. So to match the size I bought JR 4721. Now for some reason at my Futaba receiver the JR servos worked fine, but at the end of the extensions where I plug in the flying surface servos the new JRs start to do the electric boogie where the Futaba’s are steady. Anyone know why? Is it the extensions or Y connectors? Please help!!!!!

If you are using 6V without a regulator that may be the problem.

Would not reccommend 5101's on any important surface on the Bandit.

Had same problem a few years ago on a JMP T-33. Try using a JR Y connector with the amp for the JR sevos at the end of a long lead. The JR AMPLIFIED lead will change the futaba 3.3 volt signal to 5 volts that the JR servo is expecting. Stopped the jittering with this aircraft
