Default Help w motor/esc/battery combo for Losi Racing 8IGHT-E 3.0 1/8 4WD Electric Buggy

What would you get for motor/esc/battery if you were building a Team Losi Racing 8IGHT-E 3.0 1/8 4WD Electric Competition Buggy Kit? It's for a pretty fast, loose clay outdoor track with big jumps.

Right now I have an old school Jammin X1CR w a Picco .28 that is nasty but I'm tired of Nitro. I'm pretty much a newb when it comes to modern brushless/lipo stuff so any help is appreciated. Thanks

I have a Hobbywing combo in my 8ight-E 3.0. The 150a / 2200kv sensored combo.

You should be in the 2000kv and up range if you are going to race on a larger fast track.

I have had a Mamba Monster 2200kv combo, and also a cheaper TORO/Trackstar combo set.

I even have a Leopard Hobby 4072 2200kv motor, that is fairly cheap and is even more smooth and just as powerfull as the Mamba Monster 2200kv.

Many racers uses different Tekin combos, but Tekin is on the top of the pricing range, and the fact is that many low or mid priced brands performs just as well. The main difference is often no or limited warranties with the lowest priced brands, but you get the combo for half, maybe even a third of the price many just replaces if anything happens.

To have a good alround E buggy package, and if your wallet is not booming, I would much rather buy one of the lower priced combo brands and spend some extra dollars on a good servo, BEC's if needed, good radio etc.

As mentioned, I have tried low, mid and high priced combos, and I did not feel any difference.

That's why Hobbywing is so popular and used by many racers, it maybe, currently, offers the best combination of quality, reliability, performance and price.

You must decide on whether you want to run sensored or unsensored. A sensored combo does not only give you much smoother throttle control, it also offers smoother braking.

At my local tracks there seem not to be a favoured choice, some runs sensored and some not, which I think is odd, as sensored offers more refined control.

And there is the question of running 4s, 5s or even 6s. If you don't know go for 4s, as this is what the most racers use. In my part of the world (Scandinavia) I have only seen 4S use, but I can see that some US racers use 5s in combination with a lower kv motor. But if you do not want to dig into that, go for 4s.

And for batteries (lipos), many, many buy from Hobbyking.com. Lowest price and good quality. If you want to be able to use your lipos in most places, buy ROAR approved hard packs.

I have an RX8 Gen 2 with a Tekin T8 1900kv in my Caster and it's been excellent as far as speed and smoothness.

I have both gen2 tekin 1900 and 2200 hobby wing that I use in my 3.0 with the sct pro esc and both are really good. The 1900 is more versatile in that is works awesome both indoor smaller tracks and bigger outdoor tracks. The hobby wing is a beast and hard to handle on small tracks but outdoors should be very fast. I ran it last weekend on a high bite track and it was pulling wheelies down the straight at anything over 3/4 throttle. It was fun and looked cool but not the fastest way around the track. Just get the 1900 and you'll be more than happy.

so how about a Tekin-RX8-GEN2-Redline-T8-GEN2-1-8th-Scale-Truggy-Brushless-ESC-Motor-Combo-2000kV

is 2000kv high enough for fast, loose outdoor track?

The 2000kV is for the truggy and is a heavier motor, I'd pick the 1900kV or 2050kV for your 3.0-E. I run the 1900kV setup and it always has enough power on tap, sometimes too much.

thanks. what would be the disadvantages of using the 2050kv over 1900kv?

this is the track I run on if it makes a difference.

For your track I would recommend the 1900kv motor. its going to produce more torque at a lower RPM where the 2050kv is going to have the same torque but at a higher RPM which would be more suited for a high speed track with longer straights.
