5955 meltdown
Mike,Just had 1 of 2 5955's ganged on the rudder of my aw 260 35%,totally melt down,short the battery pack and total my plane,they have performed perfectly until now.I've been flying this bird off and on for over a year,no servo fighting,buzzing or jittering and boom.Now I'm a little scared to trust them,it started burning at the bottom of the case.on the circuit board.I have heard the robot people have exp.some of the same stuff.Is this something that can be upgraded or prevented?Thanks for any help![&o]

RE: 5955 meltdown
Sorry to hear about the problem. It looks like the FET's (motor controller) overheated and melted. This is typically caused by excessive long term load or a bind; it's extrememly rare to have this happen under normal conditions.
While it's no consolation, the new 7955's have an overload protection circuit that would prevent such a failure. You do need the new HFP-20 programmer to activate this feature though.
Send it the servo and we will most likely replace it under warranty.
Sorry again.
Mike.

It's a little screwed up that a KNOWN problem has caused your plane to be totaled and they didn't warn a soul and all they'll do is replace your faulty servo with an identical one.
I'd love to run such a low-consequence business!! Imagine it in another setting: "A guy got burnt at the movies because one of the seats was connected to a faulty wire, we knew it was hot but didn't want to tell anyone. So we gave him a small popcorn because he spilled the one he was carrying."
