EC135 T1 Multiple Bugs

[Isramu88]

In the latest beta, this helicopter exhibits multiple bugs:

1. HYD PRESS on both systems remains on after startup (no hardness issue with the controls). False warning light?

2. Unrealistic startup. Turbine one’s startup can take about 30/40 seconds, which is normal, but turbine 2 starts in less than 3 seconds; this is unrealistic!

3. High temperatures during engine 1 startup. The TOT can reach 950°C. No turbine can withstand that temperature and continue operating. During engine 2 startup, the temperature does not rise above 210°C, which is completely unrealistic!

4. The engine grips on the collective do not work.

I love this helicopter and it has good return dynamics, but it makes a lot of errors in its systems and that makes it lose immersion. I am HEMS pilot and I know what I’m talking about.

I think the biggest bug is the wrong attitude at pick-up. The aft left skid should leave the ground last, here the ec135 needs to pitch forward with the forward part of the skid leaving the ground last.

Also the tailrotor is extremely sensitive, even with sensitivity curves set to -50%, it is still very hard to do a pick-up without yawing all over the place.

1. was fixed in the last before the latest SU4 Beta update as of 10/7th. Afaik this was a sim wide hickup with hydraulics

2. Yes, but it’s worse than that, isn’t it? The first started engine overtorques according to the indicators for no reason! Motoring the main rotor inertia to idle or flight speed only would cause too high torque if done too fast, purely mechanically speaking. But as you say it takes a while and all EC/H135s are FADEC controlled, so hot starts and exactly this should be and are being prevented (just saying for anyone else). Otherwise, we’d be way better off manually! MSFS 2024 just doesn’t make sense simulating rotor inertia. I didn’t compare the EC to a real one but I’d be surprised if shutdown times match up even roughly. Also I am surprised you say startups are OK. I’d have bet it is also too slow. But anyway, same on the Asobo H125, where I did a 1:1 comparison for another post once. Since some SU2 update the rotor is basically a huge flywheel and start and shutdown times are twice and trice as long as they should be.

3. Nor should FADEC nor a simulation of it let it happen!

   My 50c: I am surprised a real pilot’s list is as short as this. IMHO the engine indicators in normal flight in some instances make no sense at all, starting with torque. You can pull collective all the way up and only get around 57%. As A220driv3r says the complete rotor disk to fuselage is just wrong, objectively! They made both in plane. But this throws the aerodynamic design out the window, because in cruise the helicopter now needs to pitch down the missing degrees. Hover physics are also objectively bugged. If you set it down (best seen with a little wind) there is a discontinuity between the yaw demand of the HIGE and touchdown. So you have it under control in the hover, touch down just with one pixel of a skid, click, continuity break, different yaw calculation (or whatever) → wrong pedal setting for this new situation → helicopter yaws unexpectedly. Of course no real helicopter does this, why should it? The weight load on the rotor is reduced gradually touching down not in a split second and once the skids are on the ground friction keeps them where they are. Also all simulator competitors don’t do it either. It’s just nonsense. Yet nothing is done about it

   And rotor speed doesn’t increase even if you absolutely yank it pitch up in a descend. I want to love this one too, but it is just a game version of its real counterpart, to a much much much higher degree than any real pilot could look down on simulators as “just a game anyway” IMHO
