I figured that 4s would be a happy medium and I have learned well how to adjust everything via castle link. I'm just not sure wether to get the losi conversion kit or the tekno kit. Any other help or suggestions would be great!

Thanks
The 8ight 2.0 buggy and Mamba Monster 2200kv motor is what I am running. And it is also on 4S. Like I have said in my post above, in my opinion the Losi is very simple and just works. But others like the RC Product Designs conversion has better wait distribution. If you are just getting into I would go with the Losi conversion kit like I did. Now that I am more experience I am looking at the other conversion kits. If you do go with the Mamba Monster setup put down the brake to 30% out of the box. The amount of brake the Mamba has will make your vehicle go head over heals right away. I have my punch control at 20% I believe. I put my exponential at 25% right out of the box and tuned from there. It will make it so you do blow through a set of tires in one run. With the amount of torque the 2200kv you have to be careful, but you will love it.

ok thanks Shanty, with so many kits to choose from it makes the decision difficult. I put together a tekno kit for my mugen 5t but never ran it. So I know that they are pretty easy to assemble. I would rather get a nice kit then have to upgrade later. Plus I thought it would nice to have a separate chassis for all the electronics. But if not then go with either the Losi or RC product designs?

What 4s battery are you using?

Is that your throttle expo?

Thanks

You can order any Nue motor from the castle site that you want.

http://www.castlecreations.com/produ...rs/nm1500.html

the 1512 1.5Y is 1800kv (had one in my losi)
the 1512 3.D is 1700kv

I found that in the Losi the lower KV motors were fine, but when i switched to an RC8, the gearing was vastly different, which required a higher kv motor.

I went with a Neu 1515 1.5d at 2700kv. I tried out the 2200 on 4s, didn't have enough punch, but temps were ok. went to the 2650 after driving my brothers rc8 with the 1515 1.5D. I got the punch i wanted, but at the expense of runtime, heat, and sucking the life out of my batteries.

the 2700 Nue has more punch, better runtimes, and is cooler that any motor I've tried in the RC8. With the 50t spur out for the RC8, there's plenty of gearing options to keep it sane.

I run an RC8Be with a CC 2650 geared 14/50 on 4s 5000 40c Thunder Power and I get 20 min runtime on a med sized track. I haven't tried the 2200 but my 2650 seems to run just perfectly. Motor temps are around 140 and ESC is around 130. Is anyone else running this setup?

ROAR also says that you can use up to a 4s for racing.



Ryan Cavalieri used a 2800 KV motor on 4s:

LRP SPX8 Brushless Wins JBRL Nitro Round 7

JBRL Nitro series
Revelation Raceway
October 24-25, 2009

In its U.S. debut, the LRP SPX8 brushless impressed with a 1-2 finish in the 1/8 Electric Buggy class in Round 7 of the JBRL Nitro series. Revelation Raceway, one of the largest tracks on the west coast, is definitely a power circuit. The SPX8 brushless was up to the task- devouring the long backstretch and making the long-distance jumps an afterthought.

Team Associated factory drivers Chris Jarosz and Ryan Cavalieri chose two 5000mAh batteries wired in series to create a 4S configuration to power their RC8e buggies. This versatile combination was not only powerful, but easy to drive due the SPX8's sensored design.
As a world leader in 1:10 ESC and motor design, LRP is proud to bring winning technology to racers in the growing 1:8 Electric Off-Road racing category.

Products used:
LRP80780 LRP SPX8 ESC
LRP50920 LRP Vector 8 2800kV
709 Reedy LiPo 5000mAh 7.4V 35C

I don't want to limit it down to just the Losi and the RC Product Designs. The other kits like the Teckno and RC Monster are awesome as well, just me personally like the RC Product designs and have seen it at my track with awesome success.

I am running a Thunder Power 4S 30C 5000mah pack in the buggy. Thunder Power has the new 45C packs out that are able to charge at 6C out now. SMC has some awesome packs as well. There are so many manufacturers out there and some really good companies. But Thunder Power and SMC are my favorite.

Yes that is my throttle expo.

I could get 18-20min on my track really going heard. Motor temps never go above 150 and the ESC fan almost never kicks in.

I can't believe you didn't have enough punch. The 2200kv has more punch the most of the setups out there. Lots of people I know are running a lower kv motor with higher voltage, not the other way around. My personal favorite is a 1600kv Medusa with a Mamba monster on 5S. In my buggy and can almost clear anything with a 5 foot run up, I just can't believe you didn't have enough punch. Bashing I can maybe see, but in a race the 2200kv on 4S has more then enough power that you could ever use.

Do they even make a charger that can do 6C right now? I'm not sure a LiPo sack would make me feel safe. Maybe a containment system such as this would make me feel better:

The Castle 2650 on 4S is about the sickest thing I have ever driven. The 2200 may have the torque on bottom but the 2650 has it everywhere.

I agree the thing has awesome power. But how much of that would you really use on the track. I run my 8ight-T on 5S which would just have a but more RPM's then a 2650kv on 4S. I never come close to full throttle and have dialed the punch control and exponential down. In all honesty all you need in a truggy is 4S power. I need more run time so I went with a 5S. Thats in a truggy, in a buggy I have no clue were you would need that.
