New buggy motor? (help choose)
 

well after im pretty sure i burnt up my 10xl for sure after the test tonight i decided i need to go ahead and get a good motor, this will be going in my xray xb8 with a MOD1 mm and 5s 5000 flightpower, this is gonna be raced in up to 20 minute mains and it should be no trouble because after it overheated and shut down 18 mintues into the 20 a-main over the weekend the battery still had 3.89v per cell left and it only held 2600 mah when i charged it. so with a better and more effiecent motor i doubt ill have problems with runtime.

IM AFTER LOW LOW temps thats all i care about is low temps and no problems out of it after i get it setup.


WELL nvm on the price difference the 1515 was sold i guess ill be buying new unless someone has a used one of either?

so 1515 for temps or will it really be TOO much.

I have a 1515/2.5d in a converted 3.3 Revo and I have geared up mostly to tame the torque (Wheelies)....there is a very good chance it will have too much torque, especially if you are racing...I would go with the 1512

I'd go with the 1512. The 1515 was too much power even in an MT. I tried a 1515 in TDC's Revo at the SoCal bash and it was a wheely monster. Way too much power, which is fun for bashing, but not too useful for racing. I also tried a 1512 in his Xray 808 buggy and it felt perfect. Lots of power, but not so much it was uncontrollable. :yes:

I use 1515 in a RC8 buggy, it might be too much but with some punch contol and a smooth trigger finger it really isnt a problem in my opinion.

You wont do wheelies with a buggy on a race track, there isnt enough traction! :smile:

I opt for the 1512 only because the 1515 is crazy. It throws my Completely alloy savage around like a rag doll. BUT..... as hakan said if you have good finger control it is not an issue. I am WOT guy so i am not good on a track no matter what motor i have....unless of course it is one of those N*t*o motors or a Br***ed motor.

Well i have found them both instock but the 1515 is finned while the 1512 is smooth where can i get a heatsink for the 1512 smooth can?

Well i just noticed mike has both the 1515 2.5d (1650kv) and a 1512 2.5d (2000kv) both finned i think the 2000kv is a little much for 5s but i do have a 12 tooth pinion i can use.

so which one the 1512 3d smooth can or the 1512 2.5d finned?

remember the Neu are rated for 60000 rpm. So running them at 50000 will not hurt them at all. I run my 1515 1y on 5s and it doesnt even warm up really.

You may likely need the smooth can to get the motor close enough for the gears to mesh.

Do some mesuring before you buy 1515 finned, the smallest gear I can run without modification is 16! The radius of 1515 finned is quite big and it might hit your rear chassi brace!!

Just something to consider....

I run both the 1512 2.5d and the 1515 2.5d in my rc8. I really like both. Wheelies aren't a problem. It runs cool. The 1515 is a hunk of a motor for a buggy though, but it works fine. You will need to adjust punch control a tad to tame the torque but it will run bit cooler than the 1512 in my experience.

I would say to go with the 1512. I run a medusa 60mm v2 1500 that I run on 6s in a hyper8. Plenty of motor for that buggy, and the 1512 should be a bit more powerful than the medusa. A 1515 is more powerful than an xl feigao, so that sounds to be too much for a buggy.

I use a 1512-2d (2600 kv) on 4s in my jammin buggy. I like it alot more than enough power . But then again i know when to let of the trigger :lol:.

if you want to stay with 5s go with the 3d or 4s with the 2.5d, I am taking in consideration you will be racing

Compared to the efficiency of a Feigao, the 1512 will probably be too much. I think the temps wiil be fine with the 1512, also due to the higher efficiency. Not to mention it is lighter than the 1515 which doesn't hurt at all when you're racing.

I have both the 1515/2.5D/F and the 1512/3D/S Both are great 5s motors for a buggy. It really depends what the primary use will be. If you will be bashing it and driving it around in grass and such go with the 1515. If you are building a dedicated track vehicle go with the 1512. The 1515 is a bit more versitale with the gearing it will allow you to run due to it larger size and more power, but the 1512 is ligheter and more than enough power for any track.

well what diameter are the finned nue motors? i think the smooths are 39mm arent they and the finneds are 42mm. i know i could easily fit a 12 tooth or less with the XL and mikes heatsink and prolly the smooth can but i dunno about the finned, mike only has a 1512 2000kv finned neu while impackt has the 1512 1700 kv smooth can.


will the smooth can be good enough and where can i find a heatsink for it?

you dont really need the fins with a Neu. I run the smooth 1512/3D with no heatsink or anything and I get temps around 160 or so after a 20 minute main. The neus run cool enough. The fined probably do run cooler, but how much...:neutral:

your right the whole motor mount and chassis act as a big heatsink reguardless.

Finned can is 44mm. If 12t is smallest pinion that will fit with an XL (36mm), then a 15t would be the smallest you could go with a smooth Neu (39mm). And 20t with the finned (44mm).

About 20 F according to Steve Neu.

no no no i could run a 12 tooth forsure with a smooth neu with a finned i would fit my rear brace with a 14 or 15 i believe, but all i can find instock is the smooth can so i guess i need to find a 39mm heatsink for it.

I wouldnt worry about a heat sink for a Neu...I have never heard of a Neu frying due to the temps being too hot

Would these be suitable for a buggy/truggy?

you get what you pay for.......dont expect that motor to last very long

^^^+1

1509 2Y 1820kv
Lightweight, powerful, fast, great track motor, draws 55 amps.

1512 3D 1700kv
Same as above but it draws 70 amps, and it will have more torque.

i think a found my motor!!! NeuMotor 1512/3D/F/H it the heli version, has an internal fan, aluminum rear cap for the fan, and the body is also finned! all that and its on clearance from a heli store, it is awefully big but hey i can put 3mm spacers under the center diff and it has enough clearance everywhere else that i could go down to a 14 tooth pinion. (smallest i need to go is a 15 tooth)

what do yall think its 44mm around the finned area, in the rear it has a 50mm diameter ring as part of the cover over the rear fan, and its 71mm long, and it DEFINETLY will fit with 3mm spacers under the center diff OR if i grind the 50mm ring flat where it would touch the chassis


what do you guys think? should i order it or not?

That quite a motor Ross, I was going to recommend the 1512 2.5 Ds or the 1512 2 Ds, :oops: the 3d should run real cool on 5s..:yes:. I would be a little concerned about raising the center mount 3+mm (more than the 2mm existing) there is a tremendous amount of torque there so the shims used would need to span a large area to ensure that the force is equally distributed, something to thing about.. Maybe.. :neutral:

How much for that bad boy (?)..:whistle:

Have a great one..

i figured itd be a better purchse to go ahead and get the 1515 so later on if i wanted to i could put it in a truggy or mt on 5-6s, plus it was the only motor out of my choices that Mike had instock........
