When to replace motors - one at a time as they die or all at once?

[quaddy]

Hi,

I have a Blade Nano QX, fun to fly.

I've racked up about 10 hours on it, and a motor died. Someone on Reddit said the rated lifespan was about 10 hours for those motors, which sounds reasonable for a micro brushed motor (?)

Should I go ahead and replace all the motors now, and keep a track of the hours on the new motors... and look to replace around the next 10 hour mark?

Or should I just replace the broken one, and keep doing that as needed? (Could an old motor hold back the performance.. ?)

Thanks

Hi mate as they are coreless motors and are cheap, I would change 4 at a time as your have one good motor a 3 warn, the FCB will it fly it level, but it may not be long before another one goes

Those motors tend to be a bit pricey if originals are used, ~$9 each.

You might want to try some of these. There are 2 types depending on what your are looking for.

Thanks, I have purchased some CL-0615-11 (medium speed) to have a go.

I am interested in how these motors affect battery life for the Eflite 150mah 45C. I really wanted to buy some mylipo 205mah but they were sold out.

The Bayang X9 use 6mm motors as well..those are super cheap...something like $6.00 for a set of 4....longer run tikes equals more heat which effect the motor..Its not so much how a motor effects a battery but how a battery effects the motors..205 mah should be ok as an upgrade but i would let the motors cool before flying another battery through them...Even with a stock battery, you should do that.

Cool. Have you tried the Bayang X9 6mm motors and props with Nano QX? I bought some (awaiting shipping....) for the X9 but I will try them in the nQX as well. If I know they are good I will order more now because of the month+ shipping times

I cant say i have..The bayang x9 is a "clone" of the nQX..Actually, the best of the clones and extremely popular...If you ever decide to try one out ,its highly recommended...I have an x9 myself and ,its one of my 2 favorites right now..Its extremely stable but not intended for much wind outdoors due to its super light weight, at only 19.5g with stock battery.

I have purchased a couple Bayang X9's and look forward to trying them out when they arrive
Shame can't bind it to my DX6 though

It really depends what you are using, I have had a little quads where one motor last as long as 5 of it's neighbors 2 inches from it. If you are flying a small quad that is not going to be damaged by a small fall then I'd replace them as they go, but if you have a bit bigger one that might be damaged in a fall, then replace them all as preventative maintenance.
