Make me got gears decal that will fit right there. Lol

Haha, mad max style

Some updates still struggling with the motors all of them so far failing with same problem 
. Added lights for dark rides Changed tires to Trampa Threads with hard compound its like different story compared to previous ones. Will be drilling new holes for rear feat binding to make it parallel to board my feet gets number because of that -45 angle to front…
Reused old tire as rubber dampener
Some london ride pictures
Almost killed myself once…
It looked like nice going downhill until last meter…
New lights look sick
Also after upgrading battery to 3P now I am getting like 30mi range witch is more than enough for everything

Small upgrade to my slow charger as my fan basically died yesterday 
Before upgrade:
After upgrade:
Also finishing up my filming get up for new gear drive reviewing 
I hate those gopro tool less fixing and etc I prefer old school bolts and nuts
Now just to wait for gopro itself 
(Next day UPS delivery…)

So my first GoPro Hero 7 Black test with Feiyu G6 gimbal, on backpack strap (intend to use for hyperlapse) and helmet mount (this time got real GoPro mounts for helmet so difference with before ones are like day and night that gray stuff just stuck and didn’t moved other cheaper I needed to wait until it sticked or etc before I could mount camera
With gimbal
On backpack strap
On helmet (You can see stabilisation working as helmet moves but camera doesn’t)

So yesterday I received new parts for this build: FatBoy SS Drive with 1:5 and 1:4 configurations, and 2 x 80100 180kv motors.
I was doing hyper-lapse for assembling everything but the battery died and didn’t have yet time to edit as it was pretty long one but I have some pictures from assembling everything
Soldering those 5mm bullets on these leads there pain in the ass maximum soldering power plus several minutes holding on the wire to melt them together…
Preparation for assembling the drive train
So after removing the board from the “work table” I instantly felt that these motors are from another dimension… When I was assembling it had some hard resistance to sping the motor but it would that much that pulling board felt like I am towing a truck I didn’t expect it. The magnetic forces of these motors are in another dimension…
TIP FOR MYSELF: Implement board pulling feature in ESC To assist pulling with the same RPM from motors 
Went out for outside and boy this gear drive is silent compared to inner gear
This motors transformed this board to dark side… They are massive… At first I thought I got wrong kv rating as it felt slow until I saw the speed reading that I am almost top speed but it didn’t felt like it at all.
It has nice torque but feels like it need bit more voltage and current to feel satisfied it feels like they are still starving… Running 80A motor and 80A battery… Motor constantly reaches motor amps limits and I have seen a dozen time I reached 80A on battery… So far heatsink of FocBox manages to keep up with cooling
I thought that bigger motors will heat up less but that’s not true as they are eating more current so based on IR it releases much more heat but I think the sizes make it dissipate that heat much quicker…
The battery side its bit sad right now as power consumption increased to around 20Wh/km per motor I am getting only 20km range with 12s 18Ah setup. But thank god still no sagging problems
5mm bullets with 12awg wire holds up without issue, no heating up detected.
The ride to work felt pretty nice, definitely lost some speed downgrading from 200kv to 180kv But I still have 1:4 setup but I don’t think I will switch anytime soon
If it doesn’t going to rain this evening, I will go to Hyde Park to do some filming and try some offroad as I haven’t yet unleashed its power
@tabbytabb can’t wait to test out ARC200 as these motors need POWAR and focbox’es bit struggling with them

For comparison same route but on 6384 same driving style same settings

Looks nice. Great build 
Had those monsters on my boards also (modified) and with encoders. I ended up running 6384 instead. The extra weight and loss of range with these 80xx motors just didn’t add up. But it was great fun building. I used a vesc6 with 120 motors amps.

Did you also had resistance in motors to freely spin?
Can you give a tutorial of how you wwire them up? Saw another photo where you wired the receptacle back into the standard connector.
You mean sensor connector?
I just wired simple JST connector to pins from 1 to 6 the same on JST side same on receptacle side 
i have the same motors and they dont free spin either. They have some serious magnet in them
Yep- free rolling is a total different feeling with this size of motors. A lot of resistance. And mine got hotter than 63xx series too.
Would not recommend these motors for esk8 unless your are:
- A VERY heavyweight guy
- Climbing insane hills/mountains
- Just want to do something insane that most people don’t do

After coming back home decided that I will keep them… I had some doubts before, but boy that torque… Driving in the road, 5 cars ahead of you driving slow… Small push board jumps forward and overtakes all the cars in instant No way I can get this feeling on 6384
Will wait for ARC200 and probably will get another pack of battery for group rides to mount on top when I do need range, for smalls shits I can recharge half of battery in 15mins so I do not see much problem
Just please HobbyKing make again black friday sale with half price for graphene packs
I am too lazy to edit videos today as I also have to clean up my living room after all the work.

What current were you running your 6384’s at?
Torque = current / Kv
The 6384’s are quoted as having an 80A max, which is what you are capping these giant beasts at, so you should be able to achieve the same torque levels with the smaller motors since you arent running 80A continuously.
Those 6384 can’t handle 80A without over heating and other issues… Look some previous post and you will understand why I don’t really want to go back to 6384
I am running both 6384 and 80100 at same settings definitely 80100 has way more torque and different response compared to 6384
Didn’t I tell you a while back that you’re not gonna want to go back to 63xx once you go 80xx? Now max out all your settings and start wheelieing at the push of a trigger. It’s a whole new world my friend.

Any insight why they consume so much more? In the discussion with @professor_shartsis the final word was that a bigger motor will have way less loses due to more copper, but the reality seems to prove the contrary
Maybe is just because you hammer them all the time since is too much fun? Or they are powerful but a bad eletromagnectic design that lead to lots of iron loses?
Do you speak of motor amps?
Because I got the APS 6384S 170kv and had also the aloy ring came loose on both motors and on the second two magnets “moved out” - but I was also running the vesc6 config with 120A motor amps - did not had any issue about getting hot.
Well motor amps not really matter I can set 300A amps and at 0.2 duty it will be only 3kW
