Please note that this website is currently a work in progress! Lots of interesting data and statistics to come.
Copy/paste of my rant on the 505 in another subreddit where someone claimed that it was some super modern revolutionary helicopter.
Just note this is tongue in cheek so have a read and roll your eyes and have a chuckle, there is a bit of hyperbole so dont aneurysm.
i work for a 505 operator, and also have about 2000hrs just amongst all the varients of the 206 except the LT, half the part numbers of the 505 still start in 206, the entire tail rotor assembly and tr gearbox is off a shitbanger, and the main rotor system, blades, and mrgb are all part for part longranger transplants. The arrius 2r isnt completely new, its a ec120 (2f) engine with a fadec system replacing the hydro pneumatic fuel controllers of the 2f. the hot section and the accessory and reduction gearbox internals are the same, a scratch of modernisation on a proven engine yes, but you wouldnt say the c30 was "completely new from ground up" over the c28, and the 2r over the 2f isnt either.
The fuel cell is not bigger, its 320L whereas shitbangers after ~1990 have 340 and pre 1990 can be expanded to roughly that with a range extender nozzle. The way you drain fuel from a 505 is retarded as well, there is no sump drain, no ports on the bottom of the tank like..... every aircraft i can think of... you suck it out with this stupid dick pump looking thing that gets stashed on the inside of one of the few inspection doors this helicopter has... which is a relevent point, because you cannot daily inspect the right side of this helicopter, there are no inspection doors on the right hand side to have a gawk at the breaker box, the battery, the engine controllers, rhs frame, etc... and for some reason all the cowls are held on by screwhead bolts instead of dzus fasteners that the 206 has on most of its cowls.. i reckon i could have all the cowls off the top of a 206/L/407 on my own in less than 3 minutes and without scratching them.
The circuit breaker and fadecs being mounted on the transmission deck and behind it is retarded as all the water that enters the area from rain or being washed drains onto them and fucks them out. One of ours had a wierd bug recently where halfway through the spool up the entire everything would crash, all screens blank, big crack noise, no sign of life.. not great for a light vfr helicopters typical role which is remote work..
The lithium battery is because the thing has cg issues.. there is no reason why it cant have a more robust battery as there is tons of room in that area... the cg issues are the probable cause of yet another common stupid-bell-thing.. the wasted room, there is an enourmous ammount of wasted volume where the engine controller /cb/battery/float bottle go, like the empty area behind the hatrack in the 206, it just wouldnt be able to handle the cg if that area was open for use by fuel or cargo.
The standard cargo bay is shit too, its weirdly/awkwardly deep, and the door is tiny so you cant utilise the volume anyway.
The 505 brings a flat floor, which is useful for utility, much more comfortable seating than the 206, and the float bottle is internal now instead of under the belly... but the skids are too low for a belly pod so we cant get any advantage out of that trait anyway.... oh yeah.. the floats cant be re packed by onstaff engineers, they have to be sent away.. that may have changed though.
The garmin 1000 is barely utilised by a light vfr helicopters role..its all superficial stuff to look modern, i sometimes refee tothe g1000 as just a GA toy that cirrus weekend warriors use to play make believe airliner, they are not used in larger jets or ifr helicopters or military helicopters to my knowledge.
The real engineering of a helicopter is in its rotor system and transmissions and engine.., and the head of a 505, from its 206 origins has not been touched, it still flings grease all over itself, we still have to re grease it after rain.. if you arent careful when you inject grease into the spindles, you can damage the excluder seal, which makes that spindle lose all its grease all over the helicopter in the first 5 mins of its next flight. The head and blades have to be removed to replace the seal. And the head is so reliant on grease that historically 206 have problems with brinelling on internal componants... we still have to tie the blades down because it has no mechanism to lock the teetering function as the robinsons (also old shit) do, i dont fault the 206 for these things, because it's 60 years old... but the 505 has no excuse. The helicopter still has an airspeed-torque limitation that is suspiciously similar to one of the 206 which is the torque limitation above certain airspeed due to the airframes aerodynamics bending the mast.. so you cant count "modern aerodynamics" as a win for the 505 either.
No rotor brake per standard...
Because of recently found manufacturing defects they all need a penetrative dye inspection on the collective stick every 20hrs untill bell comes up with a fix, and charges us for the privelage probably.. the cockpit has to be gutted to do this, and they cant be flown right seat solo now...
The 505 is literally the jurassic park john hammond spared no expense illusion of modernisation of the helicopter world.. a helicopter has to do shit, and the parts that do the shit in a 505 are from a 206.. and the turbomecca engine... which bell doesnt make..
i have a laundry list of ramblings bigger than this post when it comes to the cabri, as i used to work for a cabri operator and have a smudge of time in them, which i suspect most of sour grapes pedantic whiners dont.. but.. u/foxxray54 is right though that the cabri brought way more to piston trainers than the 505 did to light turbines. Having the same shitbox lawnmower engine is par for the class as no other piston manufacturer wants to touch helicopters, bruno guimbal wanted the cabri to have a merc diesal engine originally but aviation being aviation we get the finger.. at least it has plasma ignition.
A better example of a modernised helicopter using existing platform is the ec130t2 over the as350, but even that has the same heart and muscle as the also produced 125. But i forgot what point i was making
And dont tell me to get a life.
No winglets on the horizontal stab. I wonder why.
I flew Bells demonstrator 505 a while ago when they came to Canada. I didn't spend a lot of time looking around the airframe, but I was generally underwhelmed flying it.
Pro: It seemed to have a good amount of power compared to a 206. The flat floor cabin is nice. Visibility was pretty good IIRC.
Cons: The thing had, for a new helicopter, a really shitty main rotor vibration to it. Everyone loves the 206L for its smoothness, well somehow they managed to remove that. And this was the official Bell demo machine, presumably tracked and balanced as good as it can be. It also did have the optional cabin floor vibration damper to it. And it still sucked. The demo pilot sitting next to me spend the entire time explaining the huge digital dash with its 10,000 functions, probably to distract me from the vibrations? It's a VFR machine, I'd rather be looking out the window, not push it until I need synthetic vision.
