Warm Up Times of Radial Engines.

[ElAurens]

Addman, if you would share your proceedure I would be very grateful.

I have tried every way I know to get one off the ground and always, and I mean every freaking time, the engine seizes.

Nice fight today BTW. I wish our connection issues had not gotten in the way, I was enjoying our fight.

Cheers.

S!

I enjoyed our little tangle too but yeah, wish I had better latency with ATAG or that the Repka servers had the same missions as ATAG.

With regards to the G.50, I made a track for you but then as I watched I noticed that CEM is porked when recording so no use there. Anywho, here's what you need to do: 1. Give a little throttle before starting the engine, I mean like 5-10% only. 2. Start engine and wait a little, maybe half a minute or a little more until the engine sound starts getting even. 3. Increase throttle by around 10-20% and wait a little while. Might wanna open the rads and oil rad to full now as the temperatures get fairly high during take-off. 4. Give about 10-20% more throttle and wait until the temperature reaches 100-150 degrees and slam the throttle if you want to. Then engine will probably sputter and rev up and down like crazy but once it reaches 200 degrees it starts sounding like a sowing machine which is historically correct for the g.50 , you could avoid this by sitting on the airfield for another 5 minutes or so to let it warm up properly but there's no need to really. Basically you need to give small increments of throttle during warm up and listen to the engine, if you throttle too much it will shut down.

ElAurens - it only takes few minutes to warm up Mercurys in a Blenheim, too - minimal cylinder head temp. is 200C, you got to watch it very carefully and make sure you take off on the lower treshold as they go very hot on full power. Ideally, roll into take off position when they reach some 120C and if you happen to go past 200, idle till the temp drops to 200 and only then take off. Don't forget to trim your rudder fully left and do a small run up to synch your RPM.

Warming up is much faster with rads fully shut (unrealistic on the ground I know), add more power in steps (you can hear and feel when the engine stops running rough). But don't forget to fully open them on your take-off run. Once airborne, coarsen your prop, lower your boost to some +4PSI (I think) and work with your rad shutters constatnly to keep her between 200-250C. She climbs slowly, the trick is to find a sweet spot between Coarse and Fine pitch in the area around 5 -30 percent.

Interesting.

I went on ATAG late last night my time and tried twice to get the G50 off the ground.

I let it warm up for 20 minutes and the oil temp never went above 50C and the cylinder head temp never went above 100. Tried to take off and the first time the engine just started smoking and seized up, and the second time I actully got off the ground, but did not have enough power to sustain lift and crashed just off the runway.

My G50s sure work differently than yours do.

What about mix and prop pitch?

I am at a loss here.

you are not lost. the warm up of the radials in CoD is realy annoying. and not only online, keep in mind that the AI does not care, imagine flying an offline miision with such a formation, your AI comrades are alrready comming home till you have warmed up your engine

the only "help" i have is to throttle up alwasy a bit during warm up. and the italian planes are even worthervthsn the blenheim in regard to the warm up time....

put it in the WIP category i would say. you know, the game has potential
Imagine such warmup times in the planed easternfront scenaria at a cold winterday. The war is lost long before you are able to start with your I-16 (as example for a radial)

[addman]

Yup! No need for prop or mix settings just give small iincrements of throttle until cylinder temp is 100+ then u may hit full throttle. Never fails for me.

I haven't flown a real plane with radiator control, but in every checklist I remember reading you are supposed to close the radiators when warming up on the ground. Is there another reason?

[ElAurens]

Thanks for the help Addman.

I finally got her up today. BlitzPig_Raven and I flew a full tank draining sortie on ATAG this afternoon. Except for the lack of speed it's a delightful aircraft to fly.

We maneuver killed a Spitfire by getting him to stall and crash in the Channel, then we danced with another Spit till he ran away towards England like a little school girl. Good fun.

Now I wish the CR 42 and Gladiator were flyable. The Brits really need a crap plane.

Yes there is a reason, you would cook some engines even before taking off. (Merlin III for instance, esp. in a Spitfire where the water rad is being blocked by the landing gear) Regarding Mercury IVs, in the real life manual it says rads open on the ground, shut on the take off run hence my comment about 'unrealistic', it's pretty much the other way round in game.
