| My LCC MOA - Dual ESC, BL 17.5T, 3S
I want to share with you my LCC set up. ELECTRONICS: ESC: 2X Tekin RS. With Hotwire. Timing:0, Profile: F&R 1 Motor: 2x Tekin Redline 17.5T Sensored Brushless Motor. Timing:0 TX/RX: Futaba 3PKS Servo: FutabaS9157 BEC: CC BEC Battery: 3S Lipo Hyperion VXG3 MECHANICAL: Eritex MOA Upgrade. Gearing: Front 9t stock pinion, Rear 8t RC4wd pinion. CKRC CVD Rocksmith Billet Aluminum Steering Link HB Rovers White. 3-stage insert http://i169.photobucket.com/albums/u...r/L1030112.jpg http://i169.photobucket.com/albums/u...r/L1030113.jpg http://i169.photobucket.com/albums/u...r/L1030114.jpg http://i169.photobucket.com/albums/u...r/L1030115.jpg http://i169.photobucket.com/albums/u...r/L1030116.jpg http://i169.photobucket.com/albums/u...r/L1030117.jpg This is my first crawler and I would much appreciate your advice The ESC tray: Is made from the original Losi ESC tray mounted vertically in the location of the long frame brace. The RX, BEC and Harness Tray: I used the Losi Battery to hold the electronics. Mounted on top portion of the chassis. Not the best location but for now, this is temporary as I am working on moving this tray at the rear axle motor mount. The Battery Tray: Made from 2 long chassis brace taken out earlier, 1x short brace and plastic to hold the velcro and battery in place. Connection: Front Battery - powers Rear ESC, motor, BEC and Servo. Since this gets the heaviest load, my assumption was that the difference in the load will be compensated during DIG use. Once the RX tray is moved to the rear axle, then I can use bigger capacity batts and adds weight to the front. Rear Battery - powers Front ESC and motor. TX 3PKS ...I am following Harleys settings for DUAL ESC in the Electronics thread Last edited by axelram; 06-26-2010 at 12:31 AM. Reason: More info |

That is a very nice setup, dual ESC's with the Futaba radio should give you lots of control. Like I said in the other thread, get a battery that will allow you to run both ESC's together. The imbalance of the packs could cause some unpredictablility of the rig. Say you are diggind a lot with the front and you drain that pack further than the rear than your rear will feel overpowered. You could account for this with the 3PK but no reason to over complicate it. Nice job |

Power delivery is so smooth with sensored motor, lots of instant power, even heared comments from other racers thats its overpowered. I just did one course and left after that because it was family day and time was limited. I lost 3 out of 4 body clips trying to recover form out of bound, thats my next project. | |

I will use my 3 PKS in the meantime, and when budget permits, will upgrade to 4PK. After I moving the RX tray to the rear, then I think I will have a better choice of battery capacity. | |

It's funny how we can remove a huge transmission and still run out of space huh | |

Do you mean countersunk the motor mount holes? I tried trimming the buttonhead bolt to about 1mm thick, adjusted to the rear the servo mount and use washers in the servo ears. I may have to use double-side tape in the 1mm gap between the back cover of servo to help. | |

In the spirit of continuous improvement, I recycled the original LOSI ESC and servo Tray and build this bulletproof RXtray. Its mounted perfectly to the Eritex motor mount. I have to acknowledge the quality of the MOA upgrade, its a very good basis for improving the LCC. What do you think of the result? |

What do mean "yet" . I sure would like to see the newest line from Futaba. Now that you have me running Futaba in all my stuff, I will need something a little smaller for my next scale project . I completely agree, awsome job on the RX holder. Looks great. | |

Thank you very much. Here is how I build the battery tray from the 2X long chassis braces taken out earlier. Additional parts are: one short brace, plastic piece from packaging, middle post to position the battery either rear or front and the original Losi Velcro: The CC BEC installed under the battery tray. The lowest CG I can install this component: A 3s 1100maH Hyperion Lipo installed in the forward location of the battery tray. Last edited by axelram; 08-31-2009 at 12:34 AM. |

Learning a lot from this forum and from fellow crawlers in comps I participated, my LCC was completely transformed. From the base LCC with 17.5T BL, to dual BL MOA, to Chump chassis with high clearance links to the current Bettlejuice-based MOA. I though to share with you my set-up: Photo 1 Photo 2 Photo 3 Details to follow. Thanks for viewing. |
