Follow up from a much earlier thread started by Tell:

The best in a Spitfire IIa from an airfield take-off that I've been able to achieve is 17,100 feet. Having blown a bunch of Merlins in earlier attempts with fairly aggressive settings (which would've been more realistic given the panicked nature of scrambles), on this most recent attempt I "babied" the engine by keeping boost at +2 lbs or less, keeping rpms at 2200 with prop pitch adjustments, radiator cracked open, watching glycol and oil temps with an eagle eye, etc. etc. etc. Rate of climb was kept between 1000 - 2000 fpm with IAS approx 170 - 180 mph at ground level, with the expected tailing off in the thinner air to approx 140 - 150 mph as altitude increased. Used a full tank of fuel as would normally be expected in a scramble situation if the planes were well-prepped.

Anyone done any better from an airfield take-off? In any CoD aircraft? If so, how'd ya do it?

CEM in Clod is porked, the devs are aware of this and working to fix it.

My best effort so far in my 109E3...7300m and safely back down with no engine damage.

The view was quite nice too...

In a Spit 1A about 22,000, but got bored re:

The prop pitch is key too. The devs have acknowledge (I think) that mixture in the FM above 15,000 is borked.

How do I use this boost thing, can anybody explain it? - The why and how actually...

Thanks for the link -- a great thread. The YouTube clip showing the A2A Spit with the different props was excellent, as well.

Something's gotta be borked. There are too many accounts of Spits & Hurris doing wild scrambles to altitude, and they all didn't cook their engines before intercepting the enemy formations.

Dunno, but hoping to find out as well.

If only CEM was this detailed:

Yes I understand that these guys have more time on their hands to concentrate on individual aircraft and not on game engines, combat damage models etc, but wouldn't it be great if we had this level of detail?

The Spitfire/Merlin should prefer higher altitudes, according to this, and have trouble staying low on warmer days.

I'm no expert, but I'm here I could offer only a really short and really long explanation:

(1) 'Boost' is a way of forcing fuel through the engine, hence the raise in pressure (lb/square inch) plus the strain it puts on the engine by this injection.

(2) The A2A manual on the Spitfire is excellent, and is applicable to the types in COD - some great reading in there on the Merlin, and answers practically every question you could have:

The best I could do was 22000, rate of climb and speed dropped off much earlier as I had to reduce boost to keep the engine from overheating. Eventually the old girl ran out of steam.

I tried this evening in Spitfire Ia reaching 20,500 feet. Not much fun. Also discovered animation for elevator trim wheel not functioning for me. Is this a bug as well?

I want those sounds from that A2A video in CloD

Has anyone tried to reach the service ceilings using Ai aircraft in the FMB, and can they do it, either that or set it as a wapoint in the FMB and switch to auto pilot and see how it manages the engine, then try to duplicate it?

Latest patch Spitfire IIA from ground start. 26,000 slow but little drama

Yeah, I think so. Likewise the rudder trim. I have both mapped as separate AXIS on my CH Quadrant. Both trims work fine function-wise, but the animations do not. I haven't mapped aileron trim yet, but will try that later this evening.

Got the hurri rotol to 26,500 feet this arvo on the Aussie Skies server, full switch. The engine explosions above 10,000 ft seem to be gone, it was a smooth ride all the way up. Gradually dropped prop rpm to keep it smooth. At 26,500 I was full throttle, showing about negative 3 or 4 pounds boost and the old crate was pretty much dead in the air with less than 100mph indicated. Descended to the landing circuit with no systems damage showing. Running lastest beta patch. Something has been changed here.

Also, I'm treating the hurri mix in the rotol as "fixed" as per the visual indications on the control quadrant, ie full back is full rich, full forward is full lean. Seems to work correctly. Although it requires opposite control inputs - kinda weird.

Lastly, Snapper, I may be wrong but I don't think Spits had aileron trim.

Cheers.

Edit. BTW - I can't get my screenies working with the latest patch.

welcome to the club.

Michael.

I gave it a quick try -no response to aileron trim (rudder & elevator trim working normally), which fits with your thought above. One less axis to fiddle with!

Cirrus layer seems like ceiling at Caesar's Palace. 27,000 ft. seems like the hard ceiling for CoD, more likely a design limitation than a bug.

This is the altitude I could reach with a Spitfire MKIIa;

I love this game even if it is far from a finished product.
