Quick question relating to using 2 FXR's with the 4PK. When connecting the two esc's battery wiring, can I use 1 capacitor or do I need to use 2 capicitors? Thats the only question for now. I will have to redo all my wiring on my Berg now....only 1 week before Omaha  |

You want the caps as close to the FETs as possible, so use one cap per speed control.

 I am not surprised at all at how many spektrum people want to switch after reading about or using a 4pk/3pk | |

VF Dig and Your DX3R.... The DX3R just doesn't have as many options for programming so there isn't as much info. It is pretty standard, 3 position 3rd channel and EPA's are about the extent of what is typically used on it. | |

ok harley you talked me into a 4pk, got set it up and love it. Sensor is in the closet as a back up, DX3r and the two 3100,s going on the market. My big question today is have you tried to bind the 4pk with the spectrum recievers?

Okay guys, got it all wired up and using Harley's latest setup. Worked good before hooking it up. After wiring ) all the electronics, the front motor does not turn as early as the rear motor. Here is the set up. 2 FXR's (same programming on each) 2 HH 35T motors CC BEC plugged into channel 2 13 gauge wire all around 3 cell 2500 mAh lipo I put the battery connection at the half way point between the two speedos. To correct the difference, I ended up sub trimming the front and rear and now it seems okay. Should I have to do this or do I have something a little out of whack? Can't wait to get some trigger time in. Oh yeah, how do I get the dials so they can never be negative? Right now if you roll them too far back, front wheels go forward and rear wheels go backwards....hate to have that happen in the heat of battle....lol. |

Not sure why you are having that issue with the motors. Just to make sure, you did plug in one FXR at a time and program it with the throttle correct? To troubleshoot try swapping the motors from the front esc to the rear, that will eliminate the motors which I highly doubt is the problem. |

I was helping someone else out with this same issue. I have never had an issue programming either of my 2 trucks with twin FXR's. He ended up sub-trimming his as well. I just don't understand what the issue is  One thing to try, program the throttle positions at the same time for both RX's. |

I set mine up today. Seemed very simple. I am running a shafty so I didnt need to worry about mixing. I liked how I could set the point values per dial. I set my Dig to DT-3 with a 30 point value. It always starts in 4X4, hit the button once it goes to freewheel, hit it again and it locks the rear. Than just click the opposite button to sequence back through the other modes. No little glitches like I was getting from my FM M8. It was 6 years old, rode hard, and put away wet.  I was a little surprised about the battery life though. A set of duracells in my M8 would last me weeks of casual use. I charged it all night last night so it was at 7.3 volts this morning. After having it on for about 1 hour the thing had dropped to 6.5 volts. I believe the alarm sounds at 5 volts. So I am guessing the battery will last about 3 hours. Maybe this is normal for internal packs. I dont know I always used store bought batteries. Overall I am very satisfied with it so far. We will see how it performs in competition tomorrow. |

The pack voltage seems to drop off the peak voltage fairly quick but seems to slow after that. I probably get at least 4 hours out of mine. You can get the Trinity upgrade pack which will extend the runtime and make the radio about 6 grams lighter. I am working on a Lipo pack mod right now too | |

Given all of that, I almost never have a 1:1 front to rear drive ratio. I do run 1 less tooth on the rear pinion than in the front, but even so, I have less than awsome motors and I am sure that makes a difference, in fact, I run different brush springs on the front and rear motors. I too have my battery leads equidistant from the speed controls. My opinion on wire size is that theoretically, a longer wire will have higher resistance than a smaller one, but as far as the motors are concerned, the difference in resistance of the front and rear motor wires is negligable, however I am super picky, and I do it equal, sometimes, if I'm not lazy When I program my speedos, I have everything hooked up, I just turn off a mix and program the the other speedo, rinse and repeat. Havn't had a problem. I'll be in Omaha on Friday, PM me for my cell and we can get together if you are still having issues. | |

Yeah there will be one hell of a Futaba Support Group in Omaha this weekend. Myself, JRH, Jason (Hobbico/Futaba), Whoodie, The Eye, Gatekeeper, and I am sure more! 4PK's are sweeping the nation |
