1521 vs. 1527
 

hi everyone,

I think i'm going to get a Neu motor for my brushless UeG-maxx project. I've narrowed it down to the 1521/1.5D (1900kv), or the 1527/1.5D (1500kv). I'm planning on running 6s, and was just wondering which would be the better option. Would I be right in saying that 6s would not be enough to run the 1527 to its potential?

I'm going for all out power and insanity :yipi:, so if anyone has advice on which motor would do the job better, please fell free to chime in

thanks in advance

check out my muggy im running 6s on a neu 1521/1y it did 57mph easy. check out the pics and the vid. i was think of try a 1527 in it glad i didnt the 1521 is plenty enough power the truck is crazy.

Yes, I would go with the 1521/1Y on 6S. I have since went to 5S.

I am running a 1521 1.5D on a 3905 emaxx on 6S its stupid, on 8S its super dumb and on 10S its worthless......choose wisely.

Yes, apparently higher voltage will quickly depreciate the value of your driving experience...

The 1521 will be plenty, unless you're a fan of broken drivetrain components.

How'd you know, isn't everyone a fan of stupid amounts of power :lol:

If i was to run a 1527/1D (2300kv) on 6s, would that provide enough voltage, or would the amp load start to heat up the ESC??

thanks

What kind of esc are your going to use?

hmmm... you know, i haven't put too much thought into that. At the moment it will be the MMM or the Quark SSB-mk03. Both seem pretty capable controllers from the specs that have been released to the public so far.

I doubt any of the quark esc's out at the moment will be able to handle a motor that size and kv on 6s. You could get lucky, but personally I'd try and get a bigger esc for that much power.
Not sure how my quark 125 compares to the new quarks, it does ok on 6s with a 1700kv 1515, though adding another 600kv and 30mm of motor is a big jump.
A guy at my track racing a truggy on 4s and plettenburg maxximum burnt out his SSB-mk03 during practice, but I'm not sure of the details of how it happened.

wow, burnt out on 4s and a maxximum :oh:

maybe i should let others try out that ESC before i make a desicion on it :tongue:. Well then, looks like the MMM... if its ever released... :whistle:

what 'bigger' controllers are there, are you saying something like the MGM 16024?

How would a plane ESC go, such as one of the Castle Phoenix's, upto 12s lipo!! What would the truck be lacking though? It wouldn't have brakes or reverse with a plane ESC would it?

I think I'd definately want to wait for the MMM before trying to fit a plane esc to my truck though...

Don't go with the 1527. I have a 1527/1.5Y, but I'm actually not going to use it yet because the 1521/1Y already provides a ton of power. One powerfull controller would be the MGM 22418.

How are you liking that 1527 Lutach... Did Mike order that for you?.. I'm looking for 2x 1527/2.5D.

I got it a while ago and haven't used it yet. The 1521 is already breaking stuff and I can't go with much more power. I already have a good stock of Universal Joints and I just need to get are some 43T Spiral Conical Gear, 10T Spiral Bevel Gear and Hard Steel Differential Gear Set, because I know they will go as soon as I get back to speed runs :lol:.

TWO!! :gasp: what are you going to be running those in?

How would a 1527/1D (2300kv) on 6s compare to that dual Pletty setup of hcr21, oh sorry, plettenbergs :wink: My drivetrain setup is pretty much the same to that, so i guess the weakest link would be the output shaft.

A 1515 will do you good, a 1521 will make you stock up of a few drive train parts and the 1527 might not be too fun if the drive train will not handle it, pls you will have to get a rock solid high AMP controller and some very, very good lipos to handle the kind of AMP the 1527/1D will pull. My 1521/1Y has pulled a max of 169A and the 1527/1D will go over that with no problem. This is the only reason why I still haven't put the 1527/1.5Y in my truck. I might go with one of my Aveox that is the same size as a Neu 1515 just to spare my drive train.
