FusionPro Mini16 in 1/10

How many of you guys changed your spring rates when loosing all that weight?

 

[Chingon]

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.

That's possible, but you would need to use much bigger pinion gears, at least with the OD-3 anyway since you can't put a bigger spur in. I put it through some pretty hard binds the other day doing some more testing with it and it performed fine, so maybe my fears were unfounded.

I think I am going to mill the front of the OD-3 trans down anyway to get better engagement between the pinion gear and motor shaft as well as move the motor back to get some more room to mount my battery on the front axle. I might end up switching to some smaller battery packs anyway since the 1400mAh packs I am running are a bit overkill.

It's definitely sitting up higher now, but the stability is still improved since the majority of the weight I lost was sprung weight. Once I get everything finalized, I'll probably look into some lighter springs to get it sitting back down where it is supposed to.

True, but with portals, you're probably on the upper end (crawler wise at least) of pinion sizes. If it fits a 9 centered, do you think a 16-18 would fit offset?

You could also build more misalignment in your tab to rotate the motor closer to the spur. I picture something with 2 holes for the trans slot and then it's own slot to rotate the motor. Maybe you could 3d print it?

Won't that potentially make it so you can't go back to normal 5xx motors? I know my stock capra motor needs the shaft trimmed for this trans. Not a big deal, but I'd be more hesitant with nicer motors.

Hard to say without trying it or having a good drawing or model of the OD-3. I wouldn't want to go any larger than a 17T pinion anyway which is accommodated with the normal OD-3 adjustment range. You could make a mount that clamps around the OD of the motor, then you wouldn't have limitations on how deep the motor could be installed.

OD-3 clones are cheap enough, I would just buy another one off AliExpress if I needed to. I think I am satisfied enough with the Fusion Mini16 at this point to commit to building my setup around it.

I'd think the small difference could be made up by clocking towards the spur, but maybe I'm wrong.

Fair point.

What about copying the motor side of the trans but with the 16 size motor pattern?



I did just realize that they way you have to adjust the mesh on this trans could make either of my ideas null....

It's supposed to rain tomorrow so hopefully I will have some time to switch out the Fusion SE 1800 in my OG 1/10 Redcat Ascent for the mini16. I recently got the 87t 48p spur gear with slipper eliminator that Redcat came out with to reduce gear reduction. After too much math, with a 9t pinion and 87t spur the calculated no load speed would be 6.2 mph which is a hair faster than I would like.

Are you guys running metal beadlock wheels? I think I will have to put some other wheel/tire combo on there as my steel wagon wheels/tires add up to 1.98 lbs and I am thinking this little motor would be happier with less rotational weight.

I'll be curious what you think about how those 2 compare as before I saw the mini 16 just figured I'd do the se1800

Now hobbywing just needs a 380 2 in 1 that bolts to 540 plates and has a 1/8" pinion

I am running light weight competition wheels that weigh 42g each. You got me interested, so I weighed my wheel and tire combo; they weigh a total of 1.21 Lbs (550g).

[jes4man]

The SE 1800 is a better motor for sure. The only reason I want to try the mini16 is because my ascent is probably the lightest in existence. I used the steel chassis plates as templates and duplicated it in 2.5 mm carbon fiber vs. 3mm. Using shock keys as a template I made bespoke( one hole), shock towers out of 2mm carbon fiber and tweaked standoff length

 

[Chingon]

If Hobbywing made the Fusion Mini16 4S capable, it would be THE comp setup for shaft driven crawlers.

 

[Jefferson87]

Well get the trans mounting dialed in because I'll probably copy you with my "kids" build

 

[MAGNUMB]

Just purchased 4 more mini's...no going back.
Only using the full-sized Fusions on the heavy beaters now, like TRX-4 and GEN9 which all weigh over 9lbs

Anyone try 4s on these?? Does it just not work or get way too hot?? I don't really have a need for 4s or have any 4s batteries, but curious

 

[Col_Sanders]

My guess is the components arent rated for that high of voltage and it will release the magic smoke in short order, but since you have so many, you could be the one to test it.

^This. Hobbywing only rates the Fusion Mini16 for 2-3S.

Being limited to 3S handicaps direct power servos and limits the wheel speed with a particular gear ratio forcing you to run higher gearing or less wheel speed than you might want to.

 

[King Dork]

At Amain, at least, ALL Hobbywing crawler escs, motors, combos went up noticeably in price. This Fusion Mini 16 is now $79.99, the Fusion 1800 SE is $99.99, and so forth. Granted, some of these were an absolute steal and the current prices are still realistic for what you get, but damn.

 

[Col_Sanders]

Still $60 at many places. Amain's prices on some things are not in line with the rest of the market. Several styles of VP wheels for example are $75.99 there, but still $69.99 everywhere else. With that said, I expect prices on a lot of RC stuff to go up soon.

 

[MAGNUMB]

That sucks. And who wants to bet prices stay elevated even if things "calm" down.
