What Neu for 5s in 8T?
 

I just picked up a race roller 8T and would like to get a neu 1515 for it.
I have 2 4s and 2 5s tp 5000mah packs.
I would like to run 5s but could run 4s also.
I am looking for nitro like speed with good runtime,I only run it on a offroad track.
I have an 8b with a 1512 2.5 on 5s and love it,I am looking for similar power and runtime as this setup if possible.
Thanks always for the info,
Kevin

I was looking at a 1515 1y just not sure if it would be the best choice.

2.5d...this will get you about 31,000 total rpms annd very good run times...I get about 30 mins of WOT with a 2.5d/6s 5000 set up .....so I would expect a little more......if you dont need that much runtime you could go with a 2d and that would give you less runtime but more speed

I would go with a 2.5d...plenty of power for me.

i would go with the 1y you could run 4s for mild runs(still a ton of power) no gearing change and run 5s for wheelie poppin city

The 2.5d (1650kv) is good on 5 and 6s. It's ok on 4s, but depending what your track is like it might not have quite enough speed.
1y (2200kv) is good on 4s, and pretty fast for the track on 5s. If your track isn't that big it might be a bit too much on 5s.
There's also the 2D (2050kv) which will be quite similar to the 1y on 4s after a slight gearing change, and might not be as much over kill on 5s if your track doesn't need heaps of power. Could be a happy medium motor.

All three motors will work and won't be too far off each other if you adjust gearing, but which one is best for you just depends on what sort of driving your doing and what you expect.

not after the all-out top speed,just comparable speed to the higher end nitro engines on the straights,about 120 ft.
And that is not that important to me either,seing how I am on the straight about 3 sec on a 28 sec lap,but want great eff. to get the runtimes.
With my buggy,on 4s it is good on the track,at first was all i could handle,but after running the buggy on 5s now and getting some good throttle control,I will never run 4s in the buggy again.
I am thinking I may be running 5s only and possibly with next batt purchase getting the 6s tp or fp packs.
So I will have to decide between the 2d or 2.5d then it looks like.

HV is the way to go.........

say I go with the 2d and 5s right now,is it ok to run on 6s
or would I be better off with the 2.5 on 5s until i get 6s(not 100% sure I will go to 6s).
Thanks

I Run My 8ight On A 1515 2.5d/f On 5s And It Works Flawlessly....no Heat Issues/great Runtimes/and Is A Lot Faster Than People Think...

2.5D for me also. Tons of power on 5S but not overkill. I also ran it on 4S on the track and it still had good power. I was just as fast as any nitro, but I couldn't chase them down and blow by. Still had better low end, and would still win in a drag over 120ft, but it would be reasonably close. 2D on 5S is too much IMO.

The 2.5d is said to be the ultimate 5s motor and its what I have right now in my losi 8ight t roller along with a 5s 6000mah pq pack...I have not run it yet cause I'm waiting on my esc (160.24 mgm) to arrive.

cool guys thanks,2.5d it is.
mike doesn't have any,anybody know where I can get one?

Finned can http://www.amainhobbies.com/product_...ducts_id/11759
Smooth can http://www.impaktrc.com/product_info...oducts_id=2420

the finned can is 44mm right,like the 1512 finned?

Yep, the finned is 44mm... smooth is 40mm.

awesome,thanks again

I raced the 8-t today,the motor was awesome on the 5s like said.
temps never broke 130 on the motor,and for the moment the mmm is holding up.I have put a cc bec on the truck to try and take the load of the servo's off the mmm bec.
after the 15 minute main with a couple warmup laps,around 18-20 minutes total the 5000 5s pack took 4500mah,probably didn't have but another min or so in the pack.
so is 20 minutes about right for runtime or should it be a little more?:neutral:
And the nitro guys really hate my electric's:lol:
here are pics of final results after the 15min mains
Thanks again for all the help and info,
Kevin

That sounds about right for a race...

:smile:I bought a 1Y for my 8T and so far only one 4s 5000mah lipo as I was unsure if this was the best battery to go for. Reading this thread should I go for 5s instead with the 1Y?:smile:

Nice job, you kicked their ass, tons of lapping w/ the trug!:great:

Careful to not beat em up too bad or the BL may get banned lol

thanks for the compliment,the guy that qualified second was not happy with me and my flashlight powered truck:lol:
We have a florida state offroad series here in florida that is very large in attendance approx. 150-175 entries per race for the nitro race.I have been told by the series committee that i will be able to run with the nitro guys until there are more converted vehicles to have our own class:party:
But the 2nd place qualifier said that my setup was great for club racing,but not for the bigger races because it is not "allowed",then I preceded to tell him that I can run it in the series next year:gasp:
he was not happy,This is just the beginning of the fan hitting.
I don't see what the big deal is,my cars are the class I am racing in just not nitro powered.I am truely not any faster than when I was running nitro,I just prefer the elec's over the nitro.
I did have a hotbodies sponsored driver in the buggy class ask me alot about converting one of his buggy's:yipi:

oh,forgot to mention that the guy that finished 2nd was saying he had the fastest truggy,wtf.
I told him my truck was a truggy and he said,"oh but,I was the fastest nitro truggy" lmao

You should tell him to put his money where you know what is and give you a straight drag race and then we would see who was the fastest!!!:yes:

BESIDES, ENVY IS AN UGLY EMOTION!

Well done ! I like the results for the truggy. What gearing u running ?
