| Fast Forward, Faster Reverse
Ok, I have a Wraith RTR. I just recently installed a Tekin 13.5 Redline and a CC MMP. Everything works as normal but...reverse is much faster than forward. Even the motor sounds different in reverse. I have swapped wires from the ESC to the motor, I have changed settings in the ESC programming. I get no change. I also have done a lot of reading on this subject and get answers that I already know. Is there anything else that I can check, or do to make it go faster in forward. Any help is much appreciated. I am using a 2s 5300mah hard case venom battery. |

Could it have something to do with the inherent reverse rotation of the wraith drivetrain? Did u have to flip your throttle switch on your transmitter? Maybe?? Lol I dunno..... |

| Ah so it DOES have to do with the reverse rotation! Sweet. I'm rarely right about these things.

I don't know much about that motor but I would check the timing setting it at 0 should even out foward/reverse speed issue cause even when you change the input voltage to swap rotation the motor was still built to run faster in one direction with timing hope this helps (and is correct) Sent from my SPH-M580 using Tapatalk |

When applying forward throttle your motor should spin counter clockwise as viewed from the front looking at pinion. If it does not, its spinning backwards and you'll have to flip your ring gears in the axles.

| Re: Fast Forward, Faster Reverse
I had the issue where the my Wraith was going faster backwards than forwards...I had the ESC set up so that backwards was supposed to be a little slower than forwards, so I swapped the diffs around and it seems to be faster forward than back, but... it seemed like it wasn't going as fast as when the diffs were the other way around. ie it seemed like the fast backward speed from before was faster than the fast forward speed now...not sure if I'm going crazy and just imagining it. Here's a vid of it...can anyone with a HH 21t setup confirm that it looks like it's sounding/running the same as theirs or if it seems a little slow? Hopefully not too hard to tell from the vid: wraith.mp4 - YouTube |

The new Novak brushless speed control system built for the Wraith comes with a reverse rotation motor because of the reverse drivetrain of the Wraith. You are not alone! Not sure why they went to the trouble, flipping the diffs does the same thing.

Whatever the reason, I flipped mine the right way so I can run all standard motors. Sent from my highly abused iPhone using Tapatalk | |

Can you explain flipping the diffs? What exactly needs to be done?

I had the same problem with my Wraith with a Tekin pro 4 3300kv and mmp esc. I did not notice it until in went to install the VP diff. covers and the logo was upside down so i switched the ring gears and took it for a test run and it was like 20% less forward speed than reverse so i switched the ring gears back the way the manual said in the first place and run the VP diff covers with the logo upside down.

I finally got my electronics all wired up, thought the rtr diffs were the correct rotation! so thats the way i built them! Guess i need to flip them to match the manuel??? With my mmp/13.5t ballistic a,b &c matching and speed control set to normal same as when i ripped it out of my scx, its running backwards. Swap it on the controller and its slower in forward. Gotta fix it!, dam this is a fun rig to drive from what i just experienced |
