Anyone using a 1515 2Y???

[jzemaxx]

I am looking to try the 1515 2Y on a truggy and was just wondering if anyone has tried using one?? I was hoping to get maybe some higher runtimes with it then my current setup. I am looking to buy one, but NEU is backed up so going to have to try to find one soon.

BTW, I will try to run on 8S this setup. Just seeing if anyone else may have given this setup a shot.

Yes. Awesome and won't go back to 6S.

So far, I'm only hitting 60A spikes and depending on the battery I use, I get up to 45 minutes. My truggy (Mugen MBX5T with a Mr. C conversion) is very light and only geared for 34mph. I use 2 4S 3200-3700mAh packs.

Longer runtimes as in what? You want more running time between battery swaps? If so, you aren't going to, running higher voltage does not really bring longer runtimes, it does bring lower temps though.

Compared to a 4S or a 6S set up (I tested both btw), the 8S set up of mine has only been asking for 60-80A (Depending where I run) spikes and the AVG. is anywhere from 5-10A. The latest video where I used the new 10S ESC on grass, I saw the most an 80A spike and an avg. of only 8A.

Sorry if the picture is too big.

Forgot to add that a smooth driving style will play a big part of how much current you use and this will help in going further on one charge.

Do you have real world experience to justify your statement?

Just looking at your statement logicaly, it doesn't make sense. If a higher voltage system produces less heat then this simple fact alone is proof that higher voltage would provide longer run times. The lower voltage system's wasted energy, from heat, will reduce its run time. The difference of the two system's runtime may be small but it exists none the less.

My real world experience has been the higher the voltage, the longer the runtime. The difference in runtime isn't that much but is measurable.

I think he meant that the increase in runtime isn't a lot.

I had a 2Y on 8S and 10S on my Revo as well. It was awesome and always dead cold. Lots of TQ as well. IDK if you are going to get a dramatic change in runtime, but you will save all the energy wasted as heat. My avg draws were ~65A peak, but hit a few 90A here and there.

FWIW I have a 80mm 1100 kv medusa in my SavageXL now on 8S and it runs nicely. Hotter than I would have expected, but the truck is twice the weight of my Revo and the medusa not as eff as the Neu, but still good none the less. Still dialing the gearing as well. No way I could run this truck on a 4S setup and not have fireballs.

I had one of my 1527 to go into my Mayhem, but it was too big... so my 1515 1.5Y has just arrived today... that will be going into the Mayhem pro.. I will let you know how it turns out.. but it think it will be fine on 8S, for approx 45K peak...

i went from 15 mins on a 5s 5000 pack with the 1y 2200 to 20 on a tekin 1550 on 5s 5000. big difference

I went from 5s2p A123 to 7s2p/7s1p then to 6s lipo, each step up my temps went down drastically, well especially when going from 5s to 7s A123. Tons more power too... this is in a 1512/3D(1700kv.)... runs VERY cool now, at the track, usually runs around 115F after a 30 min. MAIN in ~80F weather. Weird I know!?

Really, 6s lipo is enough to keep current levels down to a safe limit, PERSONALLY... but I still have a desire to go higher in the future, say 12s.

Are you using the same pinion?
