Default 8ight 2.0 with what Brushless Combo

Hey,

I am doing up a 8ight 2.0 and am wondering what would be a good combo. I have been looking at the 8ight-E thread and it seems to me that the Mamba Monster one of the most common systems.

What would be the better option for the 8ight 2.0 buggy. The 2200kv or the 2650kv? According to Castle, they say the 2650kv is more suited for buggies. Do you people agree with that?

What are the advantages and disadvantages of each one? Like run time, power, etc.

Is there another brushless combo you would choose?

Thanks
Shawn

I don't have any experience with the buggies but I ran a Novak HV system last year and it was alright on 3s but this year I am going to be purchasing a Tekin RX8 System. I have 3 of their other systems and I like the quick and easy on board programing as well as the option to use the Hotwire and use my laptop to tune the Speed controller. As a rule running a lower KV system with a higher voltage battery you will be more efficient than running a higher KV system with a lower voltage. Tekin's motors also can run sensored, sensorless or hybrid sensorless. The advantage to sensored is the control at slow motor speeds is a little more precise, and with the Tekin systems you can actually change the timing of the motor using the Hotwire program in sensored mode and if the sensor wire comes unplugged the system keeps working unlike Novak. In hybrid mode the systems starts with sensored mode then switches over to sensorless which is suppose to be more efficient. The Mamba systems are all sensorless and I have heard good things as well about them but I do not like the fact that there are only two winds available. Tekin has 5 winds from 1400-2650KV and they have motors specifically designed for buggies and others designed for truggies. Their website is teamtekin.com

The 2650Kv setup is a missile in buggy, a controllable one though. I would say if you have gearing issues though on your vehicle (ie- only so low you can go with pinions), go with the lower KV 2200Kv motor. It is a bigger motor so its heavier, but the power we can put out with these vehicles I don't think its that much of an issue compared to battery pack weight.

[email protected] did a good job with his 2650Kv once he got it setup to his liking. I run the 2200Kv in Truggy and its a beast.

I run the MMM 2650kv combo in my 8ight-E and I run the TeknoNeu 1515/2.5D in my Z-Car buggy. Both are very fast and both motors seem to work well in a buggy. As Cain and Badassrevo have mentioned the 2200kv motor has a little more gearing options but it is heavier. I run a 2200KV motor in my ST-RR truggy. I use 4s on my buggies and 5s in my truggy.

Thanks for the feedback guys. I think I am going to go with the 2200kv with a 4S Li-Po.

Are there any recommendations on the pinion sizes I should get and also start off at.

Thanks

13 or 14 should get you in the ballpark.
