I have had very little experience with digital servos. In that experience I just can't stand them and maybe it is just because I don't understand something about them. Everything I have built so far has used 9 gram analog servos.
I owned a Edge 540 QQ from Horizon until the 3.5 gram digital servo on the rudder literally exploded in the model. I replaced that servo and the new one was bad out of the box. Just no movement from it at all. That plan now lives in someone else's hanger. I could have kept it but I was ticked off with it and a buddy was willing to pay for it and repair it.
The same buddy picked up his first balsa plane and they recommended 7.5 gram digital servos again from eflight. 2 of the 4 failed out of the box, one of them in the air.
So, is there something we are doing wrong? I know I haven't provided information on installation and such because we just lined them up and put them in like we would analog servos. In all cases they were installed in the way the instructions for the plane suggested. So is there just some general thing to watch out for with these things?
I have a balsa plane I want to put together, and I don't mind spending the money on these servos but I just can't see the point if they are this much trouble. I picked up the Twist 3D 480 and to this point plan to put the same cheap 9 grams I have always used in it just because spending near $20 on digital stuff seems to lead to tears only. Help me please!
