Neu 1515/2.5D or 1512/1.5Y, 2.5D... which motor?

[BrianG]

I'm just thinking that if enough people have a desire for a different kv rating in a 1512 case, Mike might be able to get a batch done and save a few bucks by doing a multiple order...

What Kv. are you thinking? It would be nice like AAngel said to have a ~2200Kv. 1512 motor.

bdebde, it seems like it is a recent batch of Quarks that have been cursed with faulty 'something', be it SFC (spontaneous FET combustion :005: ), or like AAngel said, S&T said they had a batch of sub pair capacitors in their Quarks.

I had both happen to both of my Quarks...

Yeah, something like 2200 or 2300 was what I was thinking since the 2d is 2600 and the 2.5d is 2000. Although, now that I really look at the Kv spread, a difference of 600 is about average...

Motor       KV     Diff
1512/1D    4875  
1512/1.5D  3200   1675
1512/2D    2600    600
1512/2.5D  2000    600
1512/1.5Y  1900    100
1512/3D    1700    200
1512/2Y    1400    300

I don't know if they could even do it; it would take 1/4 turns. A 1y would be about 2900 kv.

3 bone stock Mambas and no probs (knock on wood). Think I will stick with them!

[zeropointbug]

Wasn't sure if I should resurrect the "Quark died...blown cap" thread :eek:

So I'll post it here, I was just talking with a guy from S&T, I asked about the issues with the Quark and 6s lipo voltage; he said all is needed is an extra external capacitor...?

I was suspecting this, but can it be this simple of a fix? or inconvenient for some...

Just letting you know.

[BrianG]

I think you outta try it ZPB. :)

[jhautz]

I'll try it! As soon as I get a chance. I would love to run 6s for those goof off times when you just want the WOW factor. I havent put capcitors on my Revo yet, but I will as soon as I can and then try out 6s to see if the cogg is better than it used to be. I havent run 6s In so long due to that cogging issue that I can hardly remeber what it was like. I just remember getting some sever cogging when trying to start from a standstill.

Cant hurt to try. The quark in my revo is one of the very first that Mike sold and its still going strong. Its been thhrough many 6s packs back when I just dealt with the cogging for the first 5 minutes.

If it works that would be great. I'll let you know what I find. It might take me a week or so to get to it, but I'll do it.

[zeropointbug]

Yes, give it a try please! I can't BrianG, I only have 16.5v A123, thats it. My Quark isn't here either, should be here tomorrow maybe.

This will be great if it's a good fix! :017:

I might just consider a 7s2p A123 pack then.

That's no excuse! After all, it's only money. ;)

bdebde: yeah, a 1/4 turn would be kinda hard.

Who you talkin to?

[BrianG]

lol, what are you talking about? ;)

[bdebde]

HA, good one!

[zeropointbug]

BrianG, I just bought two dewalt 36v packs, I will make a 7s2p pack for my truck, I am determined to make this work. I would want Mike to order in a 1512/3D then, that would bring the under load, and considering volt drop rpm of ~33,000.

Or is there a different wind that would be better suited to that voltage, I us 2.8v/cell for A123 for real world calcs.

AAngel, you have every right to be upset, or frustrated about what kind of 'luck' :005: sorry... you have had this past couple months or so. We are paying top dollar for this stuff, and we expect it to work... and work how it's marketed for! It seems like every manufacturer has their issues these days, each being their own.

AAngel, where is your guardian angel? :005:

I thought 30,000rpm was more for the Feigao motors? Do you think the 1512/2Y would be the better choice then? That's 27,000rpm under vehicle load...
