Twin QUICRUN Fusion SE Questions

I am installing two Fusion SE motors on my Bully 2 but am running into a size issue with them hitting the lower links at least on the front. Have not pulled the rear yet. Has anyone installed this setup before? If so, what is the easiest way to bend the lower links or is there a different solution?
 
More than likely the answer is no. Not that many bully 2 axles cruising around on this forum anymore?!?!?!?!?

However, if you have the ability to take and post pics, them, worth a million words, and someone else may be able to better chime in.

I'll get some photos today and post
 
There actually is a thread just down this page a little about this exact topic with a video that might help. Sounds like possibly rotating the lower links 90 degrees will get the clearance but will lose steering angle.

I got the motors in by moving the links to the outside of the mount. Now I have to figure out how to get my controller linked correctly
 
I have run in to the issue of syncing both motors. I am getting the rear to sync and I was able to make my mixes but the front motor and servo aren't working. It turns on but won't sync or move steering.
Anyone have any suggestions? Transmitter is NB4 plus.

edit: I found a video that talks about removing the positive on one of the ESC's but it's built into the Fusion so would that still be the case going into the receiver?

Yes you still need to remove the positive from one of them at the rx plug. Which motor is the primary in ch2? Make sure the servo plug is the correct orientation as it should have worked when one esc will calibrate and work

So I have the servo in channel 1 and then skipped 2 and have 3 for front motor and 4 for rear motor
 
Why aren’t you using channel 2? Typically ch2 is the throttle and used as the primary ch for mixing and 3 would be the slave
Update. I have switched to ch2 and 3 now but am still having issues with the front wheels not spinning at the same. Both motors have been calibrated separately. Is there a trick to get them synced up?
 
So do they both spin just don’t start at the exact same time? If so are they even close? On my bully I’m running castle esc and 30t brushed so I tweaked some settings to get them to start at as close to the same time. I personally haven’t used the nb+ as I’m using the fs-g7p and once the mixes were set they both can calibrate at the same time for me.
 
They are running at different speeds. Best way I can describe it.
Forward - Rear is running faster
Reverse - Front is running faster

It almost sends it into a slight dig. I have a feeling my mixes or something is in the transmitter isn't set right. I just haven't found the right info online yet to fix.
 
Maybe try changing the motor rotation direction of ONE of the Fusion SE via the ESC programmer and then swap its direction in the controller also to keep it going the same direction as the other.

Mind you I have zero experience with dual motor set ups, but I did have an issue where I noticed my truck was faster in reverse than it was in forward. Even though the truck was going forward, the "forward" on the tx throttle was actually running the motor in "reverse" and into the "max reverse" setting. I fixed it by doing the above to the one motor. I feel like this shouldn't be an issue if you have the max reverse set to 100% as well as the forward but who knows.

I'm going to run it up to the hobby shop tomorrow or saturday and hopefully someone up there can help out.
 
That speed difference definitely sounds like both of them do not have reverse power at 100% which would definitely cause that kind of issue
 
With moa axles I presume you have to spin the motors opposite directions on each axle. Did you just reverse the channel on one of the 2 to reverse the direction? If so I'd try reversing the rotation in the esc settings (option 5) and switch the channel on the remote back to normal.

If you just reversed the channel you are basically telling 1 motor to drive forward, and the other to drive reverse. Probably not a big deal if you aren't trying to make 2 motors run in perfect sync. Also, you can program the esc without the program card using the power switch if you don't feel like waiting.

If the motor rotation is not different front and rear in moa axles, please disregard. It's been 20ish years since I had anything moa (old clod axled thing).

You’re 100% right about them needing to spin opposite directions.
