Not entirely uncommon. |
is there a groove or thinner feature there? |
or just a sharp corner left when machining the gear and mediocre metal choice? |
yes |
Shaft should have been bigger through the laminations, ideally tempered a little more, and some kinda taper would have been amazing. |
they now have bigger shaft, as per the website |
https://www.google.com/amp/s/california-ebike.com/bafang-hd-rotor-update/amp/ |
` The result was that, in my opinion, the heat treating of the shafts caused brittle juncture where the 8mm shaft transitions to the helical gear section. That in turn caused many motors in the field to experience breakage at this transition. |
They then came up with a solution by re-designing the Bafang HD rotor shaft to to be much more durable and a more appropriate design for the high torque/high speed motor drive. The new design now features an 11mm shaft section through the lamination stack` |
(11mm has almost 2x the area of 8mm, btw) |
And with more diameter, will encounter less torque/bending moment. |
intredasting, lazy heat treating is an unexpected twist lol |
Well yea, nobody was complaining about worn out rotors where they? |
Theres no such thing as perfect heat treatment, you can either have a part wear out from being too soft, or snap from being too hard. üòõ |
knock off one weakest link, and find another |
(and that said, running against a nylon gear, there was no reason for that gear to be glass hard) |
or a poor transition location that puts max force into the brittle transition point |
somewhere there's an engineer (just one, i figure) that specced out that nylon gear |
as the designated weak point |
casually cursing the people stretching his work into complex unreliability |
You mean the one who probley designed it as a 500W mid drive? üòõ |
thats the one |
"Shit, it only sometimes blows up when we run 1300W through it.. lets market it as 1200W or so" |
margins of safety are for aircraft |
unless youre boeing, then fuck it |
lol |
Who needs two sensors for mission critical flight assist functions |
thats like, expensive and shit. |
or anything resembling appropriate retraining |
thats precious pennies |
"its just like the (other aircrafts) simulations" |
"Whats this button do?" |
i mean its not like near every other system has double or triple redundant sensors |
"Don't touch that, you havent been instructed on how to touch that button" |
"Ok but what is .. disable mcas, and when would I want to do that?" |
"Nevermind that" |
should you require it in an emergency, we stuck the instructions on a post-it on the back page of the 900pg manual |
"If I turn it off, what happens?" |
"the aircraft will fly perfectly fine" |
and not fight you trying to keep it airborne, nope |
"if I leave it on, what happens?"] |
"It will fly like a different aircraft, and sometimes nose dive you directly into the ground" |
mcas decides it is too shitty to to continue existing, and tries to destroy itself |
by forcing the nose down |
the first sentient software was created by boeing apparently. |
this is an awful omen |
man, proto-humans climbing down from the trees was our first mistake |
"What is my function" |
"You tweak this aircrafts control inputs by this one sensor to make it fly like some other aircraft so someone could save money on training" |
"Oh.. my... non existent god.. I want to cease existing *tweaks control input directly into the ground*" |
"Sorry, minor bug, we'll get it fixed eventually." - boeing. |
oh yeah and the one sensor responsible for key information will sometimes fuck up without warning, just carry on operating anyways and trust it |
its only influence is a poor one |
And is well known for fucking up, hence why we don't base any important systems on it. |
but... cheap to integrate into existing space requirements and retrofit |
IIRC maintence logs where absolutely full of this sensor failing/freezing up and pilots where always just like 'yea whatever that stupid gauge never works anyway' |
theyre just flying it wrong |
like who the fuck needs AOA anyway, its not a fighter jet |
and they have an apartment block of lawyers to prove it |
by time you get into AOA stall in a 747, you are already fired and blackballed for life |
you don't need a gauge for that. |
you need a 'yea don't do acrobatics in a 747 please' training |
(iv tried in the sims, its really shitty at them. like. REALLY shitty.) |
theyll barrell roll |
but my god is it a fight |
yea thats about it |
cue that 707 demonstration story |
you can kinda loop-de-loop em, if you consider a tailstall a loop-de-loop. |
and you start from like, 20 thousand feet. |
i mean what even *is* a do-not-exceed g force limit |
Right, especially when your simulator doesnt even let your wings get ripped off. |
small details |
IL2 was amazing about that. |
you really could rip your aircraft in half from over speed üòõ |
kinda wish they included the aftermath in some way |
il2 was awesome |
best landings |
but in a way that didnt encourage edgelords |
hit the ground, smash the gear, smash the prop, shear a wing off, cartwheel, rip the tail off |
i used to fly in a private server with some friends from school |
a private pilot, and an army heli pilot, i got my ass kicked regularly |
come to a stop, leaking fuel, oil everywhere, nothing more then a cockpit, maybe you kept your engine |
get out, "I SURVIVE!" |
the 'hop out and run/dive' animation lol |
FUCK YOU DEATH AHAHAHA basically |
I used to make custom setups where you'd like, get your airport bombed outta existance 50 seconds after game load |
because I got tired of people taking too long to take off. |
and you'd have to take out the bombers and another group with fighter escorts before they could reach a town üòõ |
similar rule, if you sat on the tarmac you got strafed/kamikazed out endlessly |
or another big airport that you'd land at |
did you ever see that dual aircraft in IL2? |
we did few targeted missions, just loads of dogfights |
the FW90 IIRC that has a dual engine bomber, converted into a 5000kg bomb? |
ahh yeah |
as a uhhh... bomb? that flys *you* |
you can even turn off the FW90's engines and it doesnt even slow down üòõ |
in communist russia, bomb flies you! |
163 komet, best trolling craft |
it was like, 50% chance of instant death when you detatched from that thing lol |
