I have to agree on this point. I will take the Huey over the Gazelle for fun flying every time. Many of the points made here about the Gazelle's handling are true and I find them to be a little annoying at times. But I always figure that everything gets worked out in it's time with DCS modules. I know that the Gazelle will eventually be as much a pleasure to fly as the Huey.
Does anyone remember the days when people were complaining daily about the terrible flight model in the Huey? And how no one thought that it would ever get straightened out because the module had been out for such and such a time period and it should be fixed by now? Now the Huey gets a lot of praise for it's flight model by most people who fly it. And even though there are still bugs with it (as in all DCS modules), It's a favorite for a lot of people.
I think the Gazelle will eventually go the same course. In the meantime, it is fun to fly and play with the weapons systems.

I actually find both the Huey and Gazelle to be great modules.

This might sound odd, but I'm excited to hear the almost universally loved Huey once had an unsatisfactory flight model. I'm a new member of the community and it was already great when I got here!

In fact was an "impossible" to fly FM. You simply couldnt hover. And took if I remember well about a year or more to start being as it is now.

Okay there maybe something funny going on in turns, I thought about this and how I fly the Gazelle (well I mostly miss the ground so that's a start) whilst giving the Huey some love yesterday.

Depending on how you turn the Gazelle it doesn't always follow the turn, I mean it does in as much as doing the turn but the authority the tail has or should have doesn't seem to be there. I just tend to correct attitude going through the turn with pedal input (I learnt to fly the Huey first so it's automatic) I also think this effect isn't consistent but I'm not good enough to be sure.

Here is a short video, is this the effect we're talking about? at the point where the Gazelle starts to line up to the direction of travel I'm doing in excess of 100Klm/h more like 120 130 at a guess. I purposely do not correct this for a bit and I'm flying obliquely at about 45 degrees to direction of flight which after correcting attitude my IAS is 150Klm/H

Link here might be best to download then watch

Or have I totally missed something?

I do believe that is one of the major items that has been raised @FragBum .

There have been arguments that it's possible the Gazelle really does behave this strangely (by helicopter standards) due to it's flight control systems but the majority of folks aren't buying it.

@BigNewy has said on MANY occasions that we can expect PolyChop to improve the flight model so I take that as confirmation that the devs are aware that the FM needs attention. That's good enough for me.

I think the rest is largely frustration with PC being incommunicado for so long due to their "internal legal issues". If the PC devs were here participating in the discussions we would feel a lot better.

There are indeed problems with the flight model.
Personally I loved the fist 2.0 release... that was a seriously taught mo fo straight outta the box with a nasty and sudden VRS if pushed too far to the limit. The only problem at release was the super fine cyclic (which I over came with hours of practise and I came to love).

I think Polychops gotta stop reacting to feedback too quickly and stick to their guns until proved wrong!


Slow clean development of the model is just fine with me.


Light weight choppers were never meant to be easy, especially the old ones. there is no modern flight comparison to the Gazelle.


By the way, a superb combat machine polychops! She truly puts me right there toe to toe!

You don't use the pedals in a helicopter in the same way you do with a fixed wing aircraft. If you try to coordinate a turn in a helicopter with pedals you are going to put yourself in all sorts of drama.

It's not a deal breaker for me I fly for the fun of it and mostly (as can be seen) by the seat of my pants. It's just that I'm always on the pedals I didn't really notice it.



@Rotorhead11 You mean like when I break the tail assembly off.

Outside of translational lift, there is no need for pedal input in a helicopter (not entirely true, but within the limits of these sims, enough to generalise). So yes that will tear your boom off.

A simple exercise to see the way things work. Any helicopter. Lift into the hover. Slowly accelerate as you go into translational lift, off the pedals and don't touch them again until landing. It will fly great.
