Default Immelmann Troubles

Doing the Maple Flag Aerobatics mission, 7000',260 knots, hard deck 5000'. Pitch down 15 degrees try to hit 330 or so knots, I either run out of time or don't get enough speed with out going below the hard deck. Any ideas?

Thx

Immelman:
+-240 kts. start at at least 7000 gently pull back. Make sure you turn airplane up just before you reach horizontal again.

Split S:
>10.000 ft
240 IAS

Loop:
>7000 ft
> 270 IAS

Barrel Roll:
>220 IAS

Cloverleaf:
Most important is to note your hdg before you start to make sure you end up 270 degrees to east. (in case of right turn)

For any aerobatic maneuver in the a10 that requieres a huge pull-up or altitude gain start them at 325 knots. Yes u might need to go nose down to gain that speed but definetely do it above 300.
This applies to: immelman, loop, chandelle, cuban 8, lazy 8... bla bla

I feel like I must be missing something as well. I too, tried to get 'fast enough' so that I could pull off this maneuver. I kept trying for 300 IAS, but I also hit that 'out of time' fail. So I've been starting from 270 ( about as fast as I can get within the time frame required to start the maneuver). I can pull it off, but every single time, I'm nearly stalling when I come out on top... I have just about no control authority what so ever, and I have to dive a bit (maybe 5-10 degrees) to pick back up enough speed. It's really to the point that I don't see how anyone would choose this maneuver in a real life situation... Especially once you add on some weight of stores. It brings me back to wondering if the DCS A-10 is under powered compared to the real plane? Maybe someone could give me thoughts and advice? Thanks.

You're probably missing fine AoA/G control. You shouldn't have any trouble performing an immelmann.

@GGTharos I'm not sure I understand what you mean... I am pulling to hard and have too high an AoA? Not that I disagree of course, but that seems almost counter-intuitive? If I take it slower, I could see how I'd maybe lose less energy directly from the high AoA/G, but then won't I be 'vertical' for a longer period of time, so loosing more energy/speed in the long run anyway?

Ok, so, post a video (to observe technique - made sure g and aoa meters are visible) and make sure that the controls graph is visible also (rctrl-enter I think) along with the gross weight of the aircraft (fuel and weapon load). These maneuvers are designed for an aircraft of a certain GW, so it's possible that it's not your technique.

You're doing nothing wrong, if you start with 270, you're going to end up with <100.

I don't know what mission you are flying, but it's not very well designed if it doesn't allow you to prepare for maneuver.
