Author Topic: Spit IX in AH has Merlin 61 (Read 790 times)

Pyro said so, sometime in 2000, on this board.
But I can't find the thread.
Anyone know where it is?

Maybe that was his intent, but I still think they put a Merlin 70 in there. 18 lbs of boost and all, not 16.

Thats beside the great "acceleration debate" which I think is not settled by the IX having either engine. Im not going there

But I am interested in the flight model of the AH Spit IX, and what it most closely represents.

Me, I think its a H.F. IX with a Merlin 70, slower at low alt, but faster as it goes higher, with 18lbs boost max.

I have taken one up to 43, 500 ft as well. Its not ez, but it can be done.

Best climb in AH is only like 3800 fpm. For a Merlin 70 it would be closer to 4500 fpm. That fact and Pyro's statement settle the issue for me. I think he just needs to fix the boost gauge.

Best climb in AH is 3800 fpm in a IX, since when? Take it up and give it full boost, its off the chart, better than 4000 fpm initially. Thats what initial climb rate is. Even a Merlin 61 can do better than 3800.

Im so glad there is no question that HTC could not make a mistake, I guess that settles it all . Musta been the case in Warbirds too, cuz I know all the FMs are 100 percent there too

Anyways, I may very well be wrong, but then that doesnt explain the 18 lbs of boost, does it?

Later.

all id like to know is WHEN is it going to be fixed?

we seem to have a spit5 that over performs or is incorrect (according to what pyro said in that link) but has remained unchanged?

sheesh im beginning to think AH has its own fantasy setups and all we ever hear from people on these boards when we question them is how spot on they are.seems to me after all the adjustments we have seen over the last few years that it is far from 'spot on'.

As if I said anything remotely like that...

The error discussed in that thread was fixed a long time ago.

Nice hijack attempt though.

I put a smiley face there Funked, no big deal. I do see the chart shows less than 4000 fpm but thats kind of hard to measure since initial rate is very fast.

In any case I dont think 300fpm diff at 30k is a great deal, and the #s dont exactly match a Merlin 61 by any stretch either, not speed or climb rate.

I will leave it there. Like I said, as far as the acceleration debate goes, well, I will see what is posted by others.

Regards.

Well here is a whole mess of data for Merlin 61 and 70 Spits, and you can judge for yourself which matches AH better. I'd say the Merlin 61 is a closer match, but YMMV.

There was a post by Hitech or Pyro, back during the beta, I think, that said the Spit IX climb indicator reads high. It still does.

Ignore the climb indicator, and use a stopwatch to measure time to altitude. The Spit IX matches the chart on the HTC page, not what the climb indicator shows.

The AH climb figures are pretty close to the Merlin 61 figures, slightly lower in some cases. They are way off Merlin 70 figures.

If you compare the F IX Merlin 61 speed figures to the AH Spit IX, they are very close. The HF IX figures don't match in speed or climb rate, and by a pretty large margin.

Squire · « **Reply #12 on:** October 03, 2002, 04:13:23 PM »

Ok, interseting. It could be the Merlin 70 did climb a lot better then, although the speeds are close.

Did the Merlin 61 ever get 150 octane? and if so, what boost did it get max?

P.S. Hey Fd-Ski you big ape!!! how come I dont see you in AH Events with 308 RAF?

Anyways greetings.

Nashwan · « **Reply #13 on:** October 03, 2002, 04:54:21 PM »

I think the Merlin 61 was retired in 1943, before 150 octane was introduced to service planes.

heyya Taur, i was wondering what happend to you

I noticed that 416 attendance wasn't quite what it used to be..

So, when are you joining 308 ?
