Someone comment on 100 octane aircraft, please!

[AbortedMan]

I'm at work and super curious about the 100 octane performance vs 109s.

Spitfire *and* Hurricane, of course. Can anyone that has been in a couple furballs with it let me know?...average combat/cruise speed, rate of climb, stability, temperatures?

[ACE-OF-ACES]

sweet

[Osprey]

Still think the Hurricane is a bit slow. 230mph S/L @ 6.25 & 2650rpm, this should be 260mph, tit pulled got 270mph which should be 290mph. Some wierd behaviour with the throttle (boost) now seemingly linked to the RPM and mixture intrinsically. I probably just need to understand how to get the best out of it though, I can't be doing it right atm.

Remember B6 stated the boost gauges aren't updated yet so will still be showing the same numbers as last patch. Don't base calculations on max == 6.25lbs, fyi.

Also, how is the throttle action? Fixed?

[bongodriver]

Spit 1a 100 octane gives 12lbs boost with ABC selected and gives 9lbs boost on full throttle, the gauge still only shows up to 8lbs but if you put the mouse cursor over the gauge it shows actual readings.

another point with regards to performance, bearing in mind a test I recently did, the atmospheric model seems to be ISA +10...or 10 degrees C above standard conditions, and this is going to give a reduction in performance compared to data in the manuals, a rule of thumb or very rough and ready way to calculate density altitude is to add 1200' to your altitude for every 10 degrees above standard, so with the current atmosphere performance at 1000' should be roughly equivalent to performance at 2200' on the graphs.....but I somehow doubt that would equate to a loss of 20/30mph.

I was getting 290 with Spit & 280 with Hurricane at sea level.

and it tkaes about 4-5 min to balst up yout engine if you overuse those 12lb pressure. Spit is indeed faster and mroe agile in the 100 octanes, but with great power comes great responsability, and you will need a spare eye too keep the engine cool.

[trademe900]

The Spit engine with 100 octane is toast within about 2 mins of full throttle. full radiator

Where did you get this rumor from?

They only said it was not recommended to run for over 5 mins on 12lbs... in actuality, who knows how long it could have gone for. Judging by the conservative nature of most engine manufacturers, probably a lot longer...

[bongodriver]

the manual states 5 min max, this really means you should get 'at least' 5 minutes before engine damage starts to occur.

Provided the safe coolant and oil temperature limits are observed / can be maintained. Given that +12 lbs develops 30% more power than what the cooling system was sized for, there may have been issues with that.

Are there any cooling trials for the Spitfire I/II?

[Osprey]

I suspect I am doing something wrong tbh, the behaviour of the power, RPM and mixture is different than before so it's like learning as a beginner.

Sort it out before Mission 2 begins, man!

I don't know of any myself but then I am not a great one for collecting data, annecdotally the Spitfires had no issues with cooling once airborne and would maintain stable temps at full throttle with rads closed, so I see no reason temps would change the 5 min limit, I think the failure times should be randomised somewhat to make it much more like real life, but with 'hard coded' limits you just get an engine that goes 'bang' exactly on time, let's face it, there are many many stories of aircraft returning home with massive amounts of battle damage to the engine and they kept running and they certainly werent designed to run under those conditions.

[Ernst]

5 or 3 minutes? I remember manuals saying 3 minutes. Now is 5?

[AbortedMan]

Are these new engine variants so powerful that its possible ATAG may limit them on their server in the name of "balance?"

Ah! Ok! I checked:

5 minutes to II A

3 minutes for the I

They should use less IIA not for balance but for historical accuracy. IIA only comes at the final o the battle and with reduce numbers.

Most spits shoud be the IA.

[IvanK]

Plenty of cooling data in the respective Spit IIA AVIA files in the archives. The Devs have these.

The patch is awesome for me. The ricochet is excellent and raises the realism. I can't seem to stop the spitty IIa and Hurri from overheating though. I agree, it's like becoming a beginner again.

not a roumor, i jsut decided to have a fight with a friend. he was a i na E4 i was in a spitII. It was a more or less even fight, he could still zoom higher than me, but i could keep enough energy to avoid him, and take some peashots at him. after about 5 min of fight, we both had hit each other, we was leaking coolant and i had some holes in the wing. then my engine failed. He did it quite sometimes, if you dont master time management and dotn have a sharp eye, 12lb boost is not for you.

[trademe900]

I can have full blast going for much longer now if I just keep the RPM a little lower.

[AbortedMan]

The Ia can achieve approx 280mph level flight. They seem to have upped the IIa to 260mph level flight.

I've noticed 109s can keep on me in turns at low speed now. Dunno if that's a 109 or spitfire change.

You're a right propper boofhead Banned. You were closing the radiator, not opening it. No wonder it was over heating. Now you've embarrassed yourself in front of your friends. You should be ashamed. Go to sit in the corner and have a good look at yourself.

If I get banned for bagging Banned, I don't care. He deserved it.

Banned should be banned before banned get's banned!
