Bf 110C issues

[Kurfurst]

This thread is meant for bug reporting of Bf 110C series bugs for the developers.

I couldn't test them yet, but it appers that both C-4 and C-7 have the old MG FF 20mm cannons instead of the MG FF/M they had historically (C-2 had the MG FF). The FF/M could fire the special, high capacity Minengeschoss HE shells with thin shell walls, which carried considerably greater amount of explosive fillers than normal HE rounds (about 3 times the amount).

I did not have any time for performance testing, but if somebody is inclined to do so, here are the original Bf 110C-2 datasheet from April 1940, a courtresy of G.G. Hopp. Performance of C-2 should be identical to C-4 (only difference being the newer model of the same gun, which weighted the same).

What i think that has to be fixed is the violent maneuveríng of the 110's above 500 km/h.
Atm it is not possible to execute a proper highspeed dive attack, impossible to target anything, except england .

i guess, when the 109E-4 will be released (as Luthier announced) the 110C-4 and C-7 will get their historical correct MG-FF/M ...

made a map (channel) without windinfluences took a 110c4 with half fuelload and full weapons.
I flew 2 time always with full throttle (1,32ata) and 2200-2500rp`m´s
Groundlevel over sea (ca100m) i reach 440km/h; it doesnt care if engine rews with 2200 or 2500....but slow acceleration

4500m the pressure drops and i reached near 400 IAS (ca 500km/h) and cooler flaps didnt made a difference to me if full open or near closed

than it takes long time to get 6000m with loosing much power and get only 250IAS
never reached 7000m.....

i noticed outside eahaustflames went more to red with height.... probably the auto mixture doesnt work well; this could also be the reason for power and speedloss.

climbrate is ok from 0-2000m (ca 2,5min with 200-220km/h IAS) above the climbrate sink constantly and in 4000m 7min where gone....always with full throttle 1,32ata

doing a 360° roll at 4000m in ca 4-5sec.

acceleration in a dive is poor or not better than 1mot´s ....think i still can follow in a spitII

the worst thing on those 110´s here is loosing control and speedmeter goes crazy above 500km/h IAS at any height....f.e. in 2000m ; think at 600km/h the rudder is gone

Remote Compass (Führertochterkompass - no its not the compass of the Führers daughter lol) the indicator in shape of an Airplane is oszillating no matter what I do.

Since it is driven by a gyroscopic compass and only displaying the information of compensated compass (Mutterkompass) I guess its a bug.

Any opinions?

1. I had issue with all compasses (Gyro + Magnetic) stop (always display North) but mouse over does display a value ie the correct numeric value. Persisted over multiple missions , had to resart game to get compasses back.
2. The artificial horizon sometimes stop functioning.
3. Also the 500km/h (IAS) at any altitude is a big problem.

Regarding the performance.
I think the current model is quite forgiving on the side of the engine ( not by much but you can abuse the engine a bit more than the spec suggested you should )

Do you have the graph that maps the optimum climb speeds vs alt .
I'll try to match the climb times in your graph, but I think they are close upto about 4500 m , from there things start to go wrong.

Over 5000m the engines start to spit little dark smoke clouds and no longer run smooth (rev counter starts to oscillate between 2100-2400 rpm ), looks like the mixture is to rich. (no sound of backfire though)
On the oscillating rev counter , I'm not sure if that is quite correct , a real engine that oscillate rpms like that will probably break apart, and you have the heavy flywheel effect of the propeller, so even if rpms took a sharp drop , it should not be able to pick up 200-300 rpm in a fraction of a second.

Engine tooltips show manifold pressure in bar not ata, which is annoying little niggle; also, to be useful they need to display to 2 decimal places.

I noticed engine shudders passing about 2 km with full CEM; this seems to just be part of the generic high altitude mixture bug.

Translation of the datasheet would be useful, or at least a higher resolution scan; that font is pretty challenging!

It would also be useful know about VNE given the handling difficulties above 500 km/h IAS (which IMO is a nice simulation of snaking, though whether it should actually happen to the 110 at this speed is another question).

BTW, does anybody know where the oil temperature gauges are?

The gauges are on each engine. (there are three gauges on each engine , only bottom two are functional ) , oil temp gauge is one of the bottom gauges.

Seems like you don't need to open the oil coolers by much (around 30-50% will do). they don't get over 75 deg even with heavy engine abuse, with full open oil coolers oil temp drops to 60-63 deg in most flight conditions..

I even tried to keep the oil + water temp nice and high with higher alt to see if that might help with the power issues at 5000m+ , it did not.

[Viper2000]

Thanks Remo. I'm amazed you can even get to 5 km; I start getting engine trouble at rather lower altitudes.

what is the difference between 109-3 and 109-4
