I finally got everything to put my brushless 8ight together. I guess it's not really converted since it was never nitro. But it was the original kit, not the 8ight-E. It seems cheaper to purchase everything and convert an original 8ight than it is to buy the 8ight-E. Plus, I wanted the MMM combo not the Xcelorin. But I digress. Here's my pics:
Holy crap it's fast with 5S. This Zippy Rhino pack is great (so far). I got the turnigy accucell 6 charger which I'm impressed with as well.
I haven't done all the touchups yet, there's still a few wires I'll be cleaning up yet and I'll probably be getting an 8ight-E body once they're a little more available. And yes, don't laugh, I'm aware of the goofy battery setup. The 5S batt won't fit with the battery tray in the Losi conversion kit unless you have the 8ight-E body, so I put down industrial strength velcro on the chassis and battery. It hold VERY well. A little too well. I practically tear the chassis out to get the battery out to charge it. When they say industrial strength they aren't kidding. I'll probably see how I can incorporate some straps but so far it's very sturdy, even after two turnovers (I'm still learning how to deal with this much power
) plus it never rubs against anything when attached to velcro.
Anyway, I had a few questions for you guys that have done the conversion:
First, I've heard you can quiet things down a bit by getting a nylon spur. I'm used to using nylon or kevlar from my old Losi XXX. Steel seemed like a good idea when I was building the kit but wow, it's loud. Is nylon less durable than steel? The braking probably puts a lot of stress on the gears so if it's not durable then I'd probably rather go with loud than unreliable.
Also, I've been having a bit of trouble with my pinion comming loose, usually after 10 minutes or so of running. I crank the screw down pretty hard but it keeps comming loose. Is there some sort of secret with keeping it on that I'm missing?
Last, my old brushed orion revolution was pretty smooth at low speeds and startup from stop. This MMM/2200kV setup isn't so smooth. I set the motor timing lower on the Castle link software with helped but it's still pretty rough. I'm getting used to it but wondered if there's anything else to help the startup cogging that I'm experiencing. I know that this is sort of intrinsic to an unsensored setup but I've heard others say theirs is "butter smooth" and mine certainly isn't. I'll probably post on the Castle thread as well to see if they have any tips.
A few observations, 5S provides awesome power, I wouldn't go 4S personally. I know for racing some say 4S is the key but as long as you can control your throttle finger I don't see why. Frankly, I plan on purchasing a 6S next. Power for the win!!
Also, this mamba monster runs COOL! As does the motor and battery. Using an infrared thermometer the hottest I've gotten them after a little over 20 minutes of hard run time is a little over 100F (motor). Granted, it's about 40-50F out when I run so the summer might be different. We'll see.
