Something is messing up on my motor or speed control. I have no clue what in the world is going on with it. I have the E Flight 450 and matched 20a speed control. For some reason the motor all of a sudden started chattering very loud. I lost thrust and the plane came down. I picked up the plane and started the motor again and it ran fine. Then out of nowhere it started to chatter and the prop was bouncing back in forth forward and reverse very fast. What does this mean?

I have a new set up and would be very disappionted if a speed control was going out already. I just got done bragging about how easy and flawless the new electrics are compared to how they used to be back in the day. I think I jinxed myself. Anyone have any ideas what in the world this could be?

What you have described sounds exactly like what happened to my 370 outrunner a few months ago. I spent the money on a new speed control only to find out that the problem was the motor. A new motor appears to have cured the problem. The motor was not new, but did not have a ton of time on it, so I'm at a loss to understand what (if anything) I did.

You should run nothing less than a 30 amp on that.Does the motor turn smoothly by hand (disconnected?)
Also a 3 cell minimum 1500mha battery is ideal.Any less willl strain batteries.

I just got back from hobby shop and was told that my speed control was the problem. We wiggled around the motor connector and found that it fix the problem. I am going to pull the heat shrink off and look and see if something came unsolder. If so I can fix that. But if something came lose i wonder why. Maybe bad connections on the circuit board? He told me he had the same problem on his as well. I'm curious as to what it is. If it is in fact something simple like that. But if its internal electronics then I'm lost. I went ahead and bought another speed control anyways for backup.

As for running a 30 amp that seems big for my set up. I bought exactly what E-Flight recommended and what the guy at hobby shop recommended. I asked for a matched set up and the 20 amp was what they gave me.

Maybe someone can correct me,but I am sure that a 370-400 motor should have a 20 amp IF you are hard on the throttle and do alot of 3D.
A more scale model with a conservative pilot can probably do with a little less.

My 450 did exactly the same thing. I think the problem is with the stubby male connectors on the motor, and nothing to do with the ESC. I solved the problem by squeezing the female connectors very slightly on the ESC with pliers. This made a tighter connection, and the problem has not returned.

Nitro wing, the 450 is rated for 18 amps max (could even be 16, I have to recheck.) A 20 amp esc is more than enough, 30 amps is an overkill. The Park 480 generally runs of ESC of that size. The 370 will run of a 10 amp speedy, the 400 and a 15 amp speedy would be ideal ( the esc wouldn't even break a sweat if true to its rating.)

Well I removed the heat shrink hoping to find something obvious but everything is nailed down solid. I am pretty disappointed about this since the speed control was not old at all. But when asked about it at hobby shop I got the "It can happen" reply.

Wonder why it started to fail on me and only after a short while to. Was it poor quality? It sure as hell wasnt abused in anyway. I just never had a failure like this out of something that was so new. I been flying since the late 80's and never had a electronic fail on me like this. Matter fact i used the equipment for years without any hick-up. I could see something fail after being used for years and years but this is something else. That goodness our receivers don't konk out on us like this thing did or we would be looking at using control line again for control.

I even tried to squeeze the connecters to get a tighter grab on motor pins but still have same problem. I think maybe this problem should be looked at, since I am not the only one that had this issue. Maybe some beefier hardware may need to be considered or better brand of internals. This one fails

I just looked at the manual that came with my park 480 910KV
They recomend a 25-40 amp ESC
If you are a demanding pilot the 25 will burn out. I dont know anyone that would cut it that close.prop selection and flying style determine how much strain you are putting on your system.Small cheap batteries will also suffer from big bursts of drain.
The 370 will eat a 10 amp.I would go nothing less than a 12 and I'd be carefull with throttle management.
