Trouble with Neu 1521

[rhylsadar]

hi

so we do not really know yet if the 1515 has a screwed backplate?
i have to admit it surprises me that those backplates were just pressed in in some motors.
i hope the frontplates on the those bigger 1520er series are screwed.

Neu changed the 1521 design, I think, last month. I had one of each. The new Neu uses a one piece front. The end cap is pressed in and held in with 4 roll pins. E-mail Steve Neu and you will get the story.

An end bell loosening itself from the can in a surface model like a car is nothing to worry about too much. In a helicopter or plane it could mean a total loss.

My truggy had no acceleration any more and felt like i had brakes engaged. My eagletree logger recorded the following data.

You will notice those big amp spikes at the end of the run and a rise in motor temperature.

This improvement in motor design tells me i'm not the only one experiencing this issue. I wonder if the new design will prevent the end bell to come loose again in "minor" crashes or if i should secure it somehow.

Looks like my Neu is the two piece old design. I emailed Steve yesterday so we'll see what he says. Since it is no big deal I guess I won't worry much, but I would prefer to have the one piece front.

hi

if the frontplate is only pressed in it may be a real problem if you are jumping your truck a lot. the dynamics of the dead weight of the motor itself when landing will make that frontplate pop off quite easily like it happens on the feigaos.

Good point, and I plan on jumping this truck a lot.
