I looked around a little but didn't find any answer, will the 4PK work with the R603FF receiver from the 3PM? If so I might just buy one, but if I have to replace all my receivers it's gonna be hard to justify. |

http://2.4gigahertz.com/modules/modules-receivers.html It shows it working in C1 mode, which just means that receiver is older and uses a little different technology (similar to DSM and DSM2). Now go get this radio! |
Finally got my 3pk and 2nd FX-R this weekend. Spent yesterday wiring it all up and learning to program the 3pk. All I can say is, "wow". Once I got used to navigating the menus on the Futaba it was pretty easy. And the amount of things you can program with the Futaba just blows the DX3R away. And with the drop down wheel atachment you can rotate the wheel switches 360 degrees to put them where it's easiest to reach. I can't believe I've gone this long without a real radio. Thanks Harley. "thumbsup" |
I'm glad you are happy with the purchase. Just wait until you get a couple hours of run time on it and get used to the mixing options. Being able to eliminate stall by overdriving the rear is almost as nice as underdriving it to get up an incline. It will not cease to amaze you. |

Time to re-wire for dual esc's. :D |
This thread is awesome. Thanks for all the tips. I use my 3PK in all of my RC's (boats, slash, durga, crawler, scaler, etc) and I think it makes me look like a better driver than I really am (because I know how to take advantage of alot of the features) It sure makes it easy to control a 42mph slash and a 35 mph boat Here's my setup for the 2.2: PS2 - dig CH3 alternate, on when pressed and released, dig off when pressed and released (i use this 90% of the time) DL1 - 3 pos dig switch DT3 - 3 pos dig PS1 - press and hold dig switch PS3 - none Steering EXP - 0% Throttle EXP - -100% (for good slow speed control) here's the setup for the scaler: DL1 - incremental dial for variable speed winch (ch3) 20% per click DT3 - subtrim for ch3 to set the drift of the winch 1% per click same exp as the 2.2 |

Ch 1 Steering Ch 2 Front ESC Ch 3 Rear ESC Ch 4 Winch servo Still have the adjustable mix on the rear motor. The only comprimise is that the rear dig needs to be controlled by the steering wheel like most people do when using a 3PK. You couldn't pay me to go back to a single ESC. Well maybe you could but it would be expensive! :D |
Harley, I was so impressed by your overview when I read it last night that I went to the LHS and ordered one today with the steal case which is not in stock yet. I have been using an M8 with a Novak Synthesizer for about 7 years and have finally been convinced to ditch the $1000 in TX and multiple RX's I have collected for all my models over the years. So tell Futaba not only did they sell themselves a high end TX and several RX's but that they took a customer from their competitor. You are a truly valuable representative of their products and services.:-P Thanks, TL |

I really appreciate the post. I hope you like the radio as much as I do. All of this is my honest opinion on the product so I am sure you will enjoy it as much as I do. You know if you have any questions just ask. Thanks again! |
You guys see this? http://www.buggy-sport.info/include....ontentid=11181 No antenna! I couldn't find any other info on it. |
Quote:
Gonna have to call on that tomorrow. |
Quote:
Oh and if you remember, ask them when the hard cases will ship. Thanks. |

Just ordered a 4PK, short drop down extension and an angle adapter. Will have to order a case for it soon, too. Now have to sell my spare 7 Spektrum receivers....lol. Harley....this radio better be good.....or else you will hear about it at Omaha....lol |
Quote:
It is basically the same receiver as you can currently get, only there is no external antenna. Futaba is recommending that the antennaless receiver only be used in electric vehicles. No real advantage over the existing receiver except no antenna to worry about. J |

MAke sure if you have any setup questions, you ask them. Getting familiar with it is the most important part. |
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:shock: |

You want the caps as close to the FETs as possible, so use one cap per speed control. |
THIS IS A GREAT THREAD!! I hope it is stickeyed? I just used this how to to set-up my dads killer krawler...(super style) this guide worked great!!! and the vids just sealed the deal! his rig is ready to go with not that much time into programing...I never even opened the 4pk maunal:shock: all my info came from here "thumbsup" it was kinda over whelming at first but now that I have read this thread and gone through everything I realize it is SUPER easy and user friendly......I'm thinking I may sell my DX3r now:lol: thanks to all who contrubuted!8) |

I am not surprised at all at how many spektrum people want to switch after reading about or using a 4pk/3pk |
Quote:
I know of quite a few guys locally switching as well. I wouldn't be such an expert on it if it wasn't for you Josh "thumbsup" |
Sorry to Hijack this real quick but great great forum wish there was a spektrum dx3r one like this. Sorry. |
Quote:
http://www.rccrawler.com/forum/axial-ax-10-scorpion/113720-vf-dig-your-dx3r.html 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. |
My LHS called today and my 4PK was in. I dont know if anyone has mentioned this but they are running a special now where they give you a second RX for free. SWEEEEEEEEEEEEEEET!!! I am charging it tonight and setting it up tomorrow. |

this is gonna hurt 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? |
"Just go put it in the bathroom and read it over a week or something :grin:" Ha! This is exactly where i leave my 4pk manual!!! i do my best reading here!! |
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."thumbsup" |
Quote:
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 "thumbsup" |

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 :lol: |
