Castle Mamba Monster
hey guys,
I've been eyeing the new ofna ultra lx1 electric, with the mamba monster 2650kv motor. I want to buy zippy lipos but dont know which ones to get? What type of burst should they have for the mamba 2650 setup?
help!

RE: Castle Mamba Monster
IMO (and you may hear this from some other electric buggy drivers) 2650kv is too high. I'd go with the 2200 and run 4s setup. 5000mah 25c should be plenty on the 2200.

RE: Castle Mamba Monster
It kinda depends on how big your track is, and how heavy your trigger finger is. I get away with 20C packs just fine, they're barely warm at the end of a run. I let a friend drive them, same track, and they come off pretty warm, and depleted. My point it, there's nothing wrong with the 20C Zippy packs, IF you can control yourself, and you aren't on a HUGE track. 
Here's a vid of the truck and the track for reference. Running the Tekin 1700 Kv system on a 5S 4900 20C Zippy Rhino pack:

RE: Castle Mamba Monster
I read on the tower website, that the 2650 should be used for buggy and the 2200 for truggy. I havent bought it yet, just figured i ask before hand. Also wanted to know what type of lipo i should be using. I have heard good things about the zippy's, are turnigy the same quality; cause they are a bit cheaper. Thanks for the replies guys!!
1 more thing on the site the specs for the 2650 are 16.8v max for the motor, and 25v for the esc. Here comes the stupid question, If i use 6s will I fry the motor, or will the esc limit the current to the motor

RE: Castle Mamba Monster
The 2200 motor is a longer can motor than the 2650, affectively a more powerful motor. Nothing wrong with using it in a buggy and plenty of people still do because 4s on a 2200 is about 30k rpm. Staying around 30k rpm is really the most efficient range for the motor.
I run turnigy 5s 20c 5000mah batteries in my buggy (1700kv 4030 tekin motor on MMM esc). Runign higher voltage and less current really help keep the current draw off the batteries down. My batteries are hardly about ambient temperature after 10 minuter. Imo, as long as you don't over gear it turnigy batteries are fine.

From the Castle site it says the 2650 is intended for uses with 4s
"Neu-Castle 2650 KV – Intended for 4S (16.8 Volt) operation. Ideal for 1/8th buggy conversions. The 2650 is 68mm long."
and the 2200 is intended for use with 6s
"Neu-Castle 2200 KV – Intended for up to 6S (25.2 Volt) operation. Incredible in monster trucks with up to 6S lipo packs (4s lipo is the sweet spot), and works great in 1/8 Truggies as well. The 2200 is 75mm long making it capable of handling more power than the 2650. This one is the bad boy!"

RE: Castle Mamba Monster
You can use what you want, either will work. But you may consider visiting a forum dedicated to brushless conversions and see what people are running. Rc-monster had much more useful information and many more knowledgable user on the subject than you find here. The 2650 motor is the Neu 1512 size can but you'll find more people running the CC 2200 or similar. If people go with a 1512 size motor it is usually a Neu 1512 with different motor windings than the CC-Neu 2650kv motor (lower kv from almost everyone).
There are a couple reasons like lower current draw and less pinion wear because they use pinions with more teeth.

RE: Castle Mamba Monster
The 2650 cannot run on 6s safely because it will have an unloaded RPM of over 60,000. 4s for the 2650. Let me point this out, we're trying to figure out if a Chevy Cobalt would be better with a V12 or V10..................its darn near overkill either way, and way more than enough power with the 2650 or the 2200, trust me. BTW the 2650 is actually more "manageable" on 4s than the 2200 on 6s anyways.

I have found that the 2200KV on 4 cells is more than enough for just about any racing track. I wouldn't go with the 2650 over the 2200 unless space necessitated it.

, you could always go that way later! (Its fun)

RE: Castle Mamba Monster
Can someone explain the ratings on the esc, for ex Current some are rated at 35A and other at 100A. How can you choose the correct esc, does it go by the Amps on the motor; I'm asuming that the esc should be able to handle well over the motor requirments, is that correct?

A simple calculation you can do is look at the on-resistance and then apply a variant of Ohm's law
http://en.wikipedia.org/wiki/Resistor#Power_dissipation
Power = Current^2 * Resistance
This will give you a portion (not the whole) of heat that will be generated at the ESC when it actually passes through that much current.
So if you want to compare one ESC to the next, don't look at the current rating, look at the on-resistance and then the relative size of the heatsink, also consider whether it has a linear or a switching BEC.

25A to 35A is generally for 1/18th scale, 100A or more is generally for 1/10th scale. The given current rating is actually pretty arbitrary, there are many cases where companies over-rate their ESCs by 3x or even 4x their intended value.
