I broke down and bought the MD530 today, mainly because it is my favorite helicopter.
I was aware of all the issues that have been put up on Hovercontrol and the like and I know there has been a SP put out for it. I haven't put the SP on yet because I haven't been granted access to the support forums. I have installed the unofficial patch however.
If anyone from Milviz is on here, I am not bashing your product necessarily, I am making informed criticisms. I am a real life 500 pilot with time in the 369C and 520N.
Installation: Easy. The usual self installer with just a few mouse clicks to install the machine. After installation, the 'configuration manager' or whatever it's called, pops up so you can add wire cutters, various avionics upgrades, hook etc. You can configure different options to different paints which I think it's a good system.
First impressions: Fair. You are given the option of a number of (supposedly) real world machines although despite the preview screens, there are no NZ paints in there. In the sim, the machine looks pretty good. The textures are fairly crisp and panel lines seem to be pretty accurate. Overall, it looks about right. The fuselage MAY be a bit fat when viewed front on but I'm not sure about that. The pilot is too small in the cockpit although, interestingly enough, in the cockpit, the pedals are set up for a short pilot (I fly with the pedals at the longest setting in real life). When shutdown, the M/R blades have negative pitch which is incorrect. On the real machine, the blades have flat pitch. The cockpit is fairly good. The default view point is OK and of course you can change this if it doesn't suit you. All the controls seem to be modeled accurately but I haven't had too much of a play around yet. The rotor brake animation is very poor. On the real machine, it has a leather shroud around the handle that covers where it joins the pillar. In the sim, when you pull the handle out it just looks like a mass of polygons.
Systems: Below Par. This is where the model gets let down. I am a long time Dodosim flyer and as such have grown accustomed to a high standard of realism in helicopter simulation. The start procedure for the 530 is similar to the Bell 206 but it is simpler.
1: Bleed air off
2: Throttle, full open, back to the stop and into the cutoff
3: Battery switch on
4: Key, on
5: Start Pump, as required. It WILL start without it.
6: Push the start button with the right hand while your left hand is on the throttle. Monitor N1. At between 12% and 15% N1, rotate the throttle until fuel is introduced. In the 530 and the Longranger, you modulate the amount of fuel by watching TOT and twisting the throttle to keep in within acceptable limits. (on Jetrangers and 500c, d, e and 520s in general this is done automatically) Keeping an eye on TOT and N1, which should be increasing up to the 61% mark, continue to manipulate the throttle until the engine is 'self sustaining' (61% N1) Once at this point, the throttle can be opened until the collar pops out to the 'ground idle' setting.
7: I usually start the clock for two minutes here to give the starter gen time to cool down before engaging the generator. Of course in the sim this is not necessary so the gen switch can be moved to on immediately. After this all that remains is to open the throttle to 'flight idle' and you're away. Shutdown is strange. On the real machine, after cooling down at ground idle, you simple push the collar forward and rotate the throttle back towards you. This cuts off the fuel. In the sim, for some reason, turning the start pump off shuts the engine down. Pushing the collar in does nothing.
In the sim, we are good up until step 5. In Milviz's model, the start pump MUST be on. Not sure why this is. The start sequence is the real issue though. Pushing the start button seems to do nothing until the throttle is rotated at which point the sounds and everything start. TOT doesn't seem to be fluid, rather seems to be directly connected to the throttle setting. To get the engine to Ground Idle, one has to keep opening the throttle well past the idle cutoff point and in fact N1 ends up at about 80% before you can back it off to ground idle. In real life, this is just hard on the engine. Once the engine is running, I don't get a positive indication of oil pressure which is also incorrect. Even at ground idle, the needle should be at least at the bottom of the green arc. Another thing I noticed was the Ammeter. I'm not sure what is going on with that but it is always showing a charge, even when the starter is energized. On the C that I was flying, during the start, the Ammeter went to around -30A initially. Once the engine is started, opening the throttle to 'Flight' shows up another problem. The throttle travel is far too short. Now this MAY be a C30 thing but on the C18 and C20, you have to open the throttle quite a bit to get the needles to start moving. The torque needle doesn't appear to move while winding the throttle up either. In real life, this limits how quickly you can open the throttle.
Flying: Fair to Good. Picking up into the hover is very easy. The 530 has plenty of power in real life and at sea level gets off the ground with no troubles. The sim is the same although, I think I should be using quite a bit more left pedal than is required. It's nice and stable, just like the real thing. Going through translation is no big drama. The sim has force trim modeled which while not accurate to the real aircraft, is a great thing to have for those of us with springy flight sticks. I hear this is being disabled in the patch though. Once in the cruise, the machine balances itself more or less which is certainly accurate for a C but I thought the 530 would have required more left pedal. I may be wrong on this though. One big thing that I did notice was that at 1500ft with full fuel, I was able to fly at 130kts with FULL collective. This most certainly inaccurate. I have NEVER pulled full collective in ANY helicopter. To do so would either cause a large RPM droop and subsequent engine failure, or, over temp and or over torque, followed by an engine failure. The 500 series has a LOT of collective travel. Coming into land, it is nice to see that it doesn't like slowing down and I had to do what I do in real life which is, stand her on her tail and then kick in a whole heap of left pedal and stop sideways. It doesn't sit left skid low while in the hover as the real thing noticeably does. Overall, it's actually quite fun to fly.
Sounds: Poor. While at first glance, the sound appears to be well done however, on closer inspection, the looping in the hover and at low speed is terrible. There is actually a gap in between the sounds. While spooling up and down, there appears to be a 'swoosh swoosh' sound much like a Jet Ranger. I'm not sure where this has come from. The start pump doesn't make any noise, which at least in the C and 520 is incorrect. I also think that the battery noise (gyros) isn't really up to par but this is a small issue. The interior noise in flight is as it is heard through a good headset or helmet but I think that the transmission whine should be a little louder. If the wind is light but gusty on the ground, then the wind noise starts and stops really abruptly and is really annoying. I'll probably delete it.
Other: I noticed while flying from an external view, that the T/R pitch links don't move with the T/R. It's very odd. There have been complaints about the wire cutters being wrong but I cannot confirm that. The doors are strange with no door vents. While this may be correct, it is certainly not prototypical. I'll probably find other things as time goes on. The GPS can be called up as a 2d panel which I like as in the VC, it is down on the tunnel. Quite hard to look at without Track IR.
I am running a laptop (I7 3610 2.3Ghz, 8GB RAM, NVIDEA 610M, Windows 7) that is a couple of years old now and I was worried about how it would perform. With Orbx's NZSI and their AI package, I flew from Gore to Balclutha with Orbx's airports and REX Essential w/ OD. Most settings in FSX on the higher side. I averaged 15 to 20 FPS the whole way with the usual micro stutters. It certainly wouldn't be like that around a city.
I'm sure that as SPs are released, the 530 will improve however at the moment, I think that it is suffering from poor testing and I won't be flying it exclusively.
