Very cheap BL motors - check them out before they go

[Kpowell911]

What on gods green are you guys going to use these in? They may be cheap but do you have any wacky ideas for them? Cause even at £3 I think its a waste. Hence why they are for sale so cheap!

Planning to use mine on a 1S car build.

Same, ones going in my pan car, run on 1s and see what sort of speed I can get out of it and the other, I've got a project in mind

[Si Coe]

1S use in a pan car is about what they are designed for. Literally anything else - certainly any 2S applications - they are more trouble than they are worth.

The reason they are cheap is because:

1) They are old

2) Nobody wants them.

 

They are old because they haven't sold, so clearly thats really two lots of nobody wants them.

Speed runs on 2s

[Si Coe]

You do know that the 2.5t version at least was actually only rated for 6V use? It was designed in the pre-lipo days when touring cars used to run 5 cell NiMH. Just running on 2S is stretching it a little!

But at £3 or so it interesting to try them out

arrived today. 

 

Just remembered, i also have a 4.5t version of this, its in my vaterra v100 and that goes like stink 

 

 

Also - forgot to say, you need a sensored ESC for these to work

[Si Coe]

They will work without a sensored esc (or at least the 5.5t and 10.5t versions I've had could) but they will cog like crazy.

 

I was doing the maths on these motors and I realized that a 12000kv motor on 2s is pushing 100 000 rpms on a fully charged pack at no load. That's the equivalent in rpms of running a 4000kv motor on 6S!!!!

 

For £3 I was tempted, but these are still crazy, crazy motors......

[Carpmart]

I went for the 3.0T ones... Much more sensible....  

[m1tch_87]

I have a selection of the 2.5T, 3.0T and the 3.0t sensored just to try things out, quite impressed that they came with a sensor cable as well.

So did mine....  

[TTshadowTT]

I can actually get these cheaper

[m1tch_87]

What ESC rating should I go with? I think I saw the 2.5t version running a 110a constant?

One speed run maybe lol. You won't be able to gear low enough to keep temps low.

[Bigjimknickers]

So these are not suitable for a TT02R then?

shame.

[cookie666uk]

there must be a way BJK!!!

It will technically work, but will have poor acceleration, a mental top speed and the probably melt everything plastic around it.

 

i wouldn't put a high KV motor anywhere near a Tamiya non TRF tbh...

would one of these work well connected to a propeller? not on a plane.... idea for a winter project is brewing...

Out runners rather than in runners are the 'norm' for running props... But hey,movie it a go!  

[cookie666uk]

been researching and it may take a little while to find a prop that will produce acceptable amp draw but should be a goer!
