FusionPro Mini16 in 1/10

Probably quite a bit, also cheap enough to have a spare available to swap out if needed.just wondering how much abuse this little thing will take
Mine came in today too. Going to order the od4 transmission and some more dlux driveshafts tomorrow or Friday.
Just in case anyone was wondering, the mini 16 won't fit a VFD with stubby kit. Its too long.

They are fairly cheap and hope it's a viable option going forward.
Also have enjoyed these in some small Tamiya bashers

How much does your truck weigh?
Gearing is one concern I have. The transmission I'm looking at only has 3:1 reduction. I think running a 9t pinion might be ok. May have to swap to UD gears in the portals. I currently have OD portal gears front and rear since the old Vanquish UD gears had a reputation for breaking. They've done some redesigns on them over the past few months and are supposed to be stronger now.
Just weighed the truck. Currently sitting at 5lbs 12oz. I could easily drop some weight if i wanted/needed. This is running the jconcepts tucked k10, my aluminum grill, headlights, inner fenders, etc.
Just the motor swap should drop a 1/4 lb if my conversion is correct (~120 grams). I can't remember, but I believe I'm running the stock 56t spur and 15t pinion on the fusion se in that car. I'll likely pick up a 9t pinion as well to start.
I think it'll be fine for crawling. Heat isn't a big concern since it easy enough to keep an eye on while testing. I figure worst case I bend the shaft and it's a $60 failed experiment.

I stopped in to hobbytown to pick up a pinion for this motor. I ended up having them solder the connectors for me while I was there. They also had a 2mm to 1/8" adapter. I'm going to see if i can drill this out to fit the motor. If not the right adapter is on the way from Japan. Lol
I've heard of some people also using a 2mmx3mmx0.5mm brass sleeve stock off ebay @ 200mm long. Never tried, but should be able to make a bunch from it
I was looking at brass initially before finding the actual adapter. With 32p gears there is probably enough engagement that it doesn't need to be perfect, but it'll run smoother and quieter if it's closer to perfect.
That said, drilling out the 2mm adapter worked as well as I expected, not as well as I hoped since the one end is open. It's got a slight wobble. It fit well enough to test the install, but I'll wait for the proper adapter before I really run the car.

Anyone got theirs installed yet? I got mine in the mail Saturday and drilled out a Latrax 14T pinion with a #43 drill to get it to fit the motor (2mm is apparently not the same as 2.3mm). I am still waiting on the motor adapter on its way from China and I still need to solder on an XT60 and JST connector for my direct power servo. I am getting excited for this experiment, hopefully it works out well.
How does it do if you really bind it up? The fact you went from a 9T to 10T pinion is promising.
Went to the 10T as i didn't want to keep it at full throttle for trailing and i felt it was doing just fine to be able to increase to a 10.
Well i didn't change my slipper setting from when i moved from the Fusion SE 1800 to this and i managed to engage the slipper with the mini16. Not sure that tells you much....it did everything i wanted it to do and happy i can reduce some serious weight and have a 2n1 system for only $70. Not changing all my rigs from the SE/540 Pros to the Mini16, but just the ones i want better side hilling and ones that are a little too heavy. Plus it's fun just seeing what this little motor can do.
I'm equally impressed with it in some of my bashers, like the Arrma Grom, Tamiya Blackfoot, Tamiya TD2 buggy.....these for sure don't need heavy 540 sized motors for what i'm doing with them. The real test will be on this rig below with tracks in the mud
They need to start including the adapter plate with these

I got mine running as well. I was able to modify the adapter I had on hand and get it centered up and the pinion is running true now. I just got a long 10t pinion i had ordered today. Not so concerned about the gearing, just didn't care for the short pinion sitting out towards the end of the motor shaft so I found the long pinion.
I've only run it in the garage so far. The on the fly drag brake adjustment works well. I need to adjust a couple esc settings to my preference, then I just need time to get it on the trail.

The 2.3mm pinion adapter came in from Japan today. I went ahead and swapped to the 10t pinion along with that adapter. The pinion is much more true now running on a proper sized adapter so I'm happy with that. The one I had drilled did ok, but definitely wasn't perfect.
Fun fact, I can remove and reinstall this motor into the vfd trans without removing the transmission.

Well, so I finally got mine together and did a first test run. I am a little concerned about putting it into a real bind right now since to get the pinion to mesh with the knock-off Chilux OD-3 transmission I am running, I literally had to put the pinion set screw at the very end of the motor shaft. The 2.3mm motor shaft isn't particularly confidence inspiring and I am worried about the pinion spreading away from the spur inside the trans and skipping/stripping teeth.
The parts I used to make it work were a Traxxas Latrax 14 T pinion I had to drill out with a #43 drill (I was dumb, there are plenty of 2.3mm pinions available), a Chinese motor adapter off AliExpress ($2.50 vs $10 HW wants), and I swapped to an XT60 connector and added a JST connector to work with my direct power servo. If I were starting from scratch, I would go with an XT30, but my batteries are all XT60s and I already had a bunch of female XT60 connectors.
XT60 connectors are suprisingly heavy compared to XT30 connectors in addition to the added bulk:
The weight of the Team Brood Ravage 5 slot 11T motor, HW1080 G1, and BS6 receiver the new combo is replacing:
The weight of the new Fusion Mini16 and FS2A receiver (pre-assembly):
A 171g weight savings!
After a quick run in the living room, the pinion worked itself off the motor, so I re-cleaned everything and filled the pinion with threadlocker in an attempt to keep it from rocking on the motor shaft and working itself loose again. I can easily mill .150" off the motor mounting face of the OD-3 trans which i will probably end up doing to get the pinion slid down for full engagement with the motor shaft.
Based on Holmes motor speed chart I figured my Team Brood Ravage (machine wound) 5 slot 11T motor was equivalent to ~2500kV and since I was running a 17T pinion, I needed to go with a 14T pinion with the Fusion Mini16 (3000kV) to end up with the same wheels speed. My crawl ratio with the 14T pinion is at 82.8:1 in the front and 108.1:1 in the rear. This video is on 3S and I lost a bit of wheel speed. I think I will try out a 15T or 16T pinion. The low speed creep is definitely better than the old setup, I am just not sure how well it will do when I get it really bound up.

I put it through some pretty good binds today and it did great. The Hobbywing FOC is very impressive. I didn't run very long, but the Fusion Mini16 was cooler than the NSDRC RS700V2 servo at the end of the run. I am still not completely confident that it will hold up to full-on competition abuse, but I am feeling better about it now. I need to change over to a 15 or 16 tooth pinion and see if I can get some wheel speed back.
Great news! It's pretty crazy what this little motor can dish out.

I wonder if you could ditch the adapter. Run the bottom screw right into the motor and then make a little tab that bolts to the trans and motor?
Might have to use 2 screws on the trans side so it doesn't just pivot and loose mesh.
