[RELEASED] IniBuilds Messerschmitt Bf 108 Taifun

Thanks for that,perhaps you could tell me where that switch is as I’ve looked everywhere and cannot find it…

It can’t be missed! BUT… Are there different kind of cockpits? Vintage and modern? I didn’t even notice! I already deleted the plane! At least the modern version has a radio switch/volume button…

It can be missed if you’re using the Classic Cockpit. In order to see the radio (and switch it on) you have to deactivate the “Classic Cockpit” function in the EFB.

This interior will be included in Bf-108 from Spanish Civil War.

Version with black panel too.

Very good! The black flight stick is a nice touch. How about changing the gear lever as well to make the three look alike?
The Senorina as well, although most German aircraft during the Spanish Civil War were flown by German pilots, I believe. Well, that doesn’t mean they didn’t get friendly with the natives :wink:

As I pointed out in the inibuilds forum (LINK), I experienced a glide ratio (throttle closed) of roughly 25:1 (including part of the glide with gear down!) - that has to be too much!
Other than that, the aircraft is a joy.

A glide ratio of 25:1 would be ludicrous. Most GA aircraft are around 8:1 to 10:1.
25:1 is already sailplane territory

Thanks for the feedback. With regards to the lack of aileron roll capability, having discussed this with our flight model developer for the aircraft, this is in line with what we’d expect. 100 kts is a good 40 kts short of cruise speed and given that the real aircraft wasn’t designed with aerobatics in mind, a good amount of forward vector is required to have enough speed to power through an aileron roll. It is possible to get a full roll, just need to be at high enough speed and altitude.

it just wont slow down

That’s the 3rd time your reaction to feedback comes across to me as:

“Thanks for the feedback, but the plane is perfect as it is so basically we don’t care”

and the three major issues:

  • ground behaviour
  • low aileron authority at medium speeds
  • inability to slow the plane down/high glide ratio even with flaps and wheels extended

are being dismissed and sold as realistic, when many people are of the opinion that it simply can’t be.

All in all it reminds me a little how Mathis Kok reacted to critics of the Twotter and some reactions by Aeroplane Heaven to flaws in the Electra and Spitfire. And those two are not exactly known for stellar customer relations.

I realise of course that the Community isn’t always right either, that you can’t make everyone happy, and that - as a company you have a certain pride in your product and want to show some integrity instead of caving in to demands.

So just to illustrate why I don’t believe what you just wrote about the issue with aileron authority is correct:
with all non-aerobatic GA aircraft I have ever sat in, maneuvering speed Va is below structural cruising speed Vno, so being able to do a barrel roll only close to Vno - 140 kts (aerobatic plane or not) would be ill advised in any case. The chance of serious structural damage at that speed would be several times higher than at 100 kts since those forces don’t grow linearly but exponentially.

Also since the Bf108 served as a testbed for the Bf109 fighter I can hardly imagine that it would behave that way. I don’t expect your flight model expert has ever tried a roll in a Bf108 himself, has he? So maybe there is some room for tweaking?

Thanks for considering
best regards

Its a good idea also to improve slats behavior finally. I never noticed that they close on straight flight with AoA=0 or even on minus. I know perfectly well how they behaved in the Bf-109, its done in many simulators, as before in FSX, DCS or IL-2. In the model of Bf-108, the behavior is exactly the same as in the Bf-109, and they have never closed for me in the model. It’s a really simple design, with increasing AoA they open, otherwise they are closed, especially in dive. They’ve never been closed here. I think it’s worth improving. Something is wrong with the animation or code.

:point_right: Users: can you check it also, did you noticed closed slats any time?

I can get her to roll at higher speeds, but only just, and only with full aileron. If this is how she is expected to fly then that’s fine. It seems odd to me, but then I’m not a pilot and have zero real world experience so who am I to argue? I did some research and could only find one mention of the Bf-108 being “fully aerobatic” (actually was in reference to one being sold here in NZ) so I don’t have much to go on other than that and rumour. Either way, I enjoy flying her.

But that’s not how it works on the Bf108!
The slats on the 108 are triggered by airspeed, unlike the Bf109 slats which are triggered by AoA. They smoothly pop in at exactly 130 kph and stay there until speed goes below that again., and they do it so reliably that you can use the slats as an airspeed indicator. That’s for the IRL Bf108 of couse, not the inibulds rendition.

Hmmm. Where did you get this information from :face_with_peeking_eye: ? Slats are designed to improve air flow at low speeds (properly direct the streams that adhere better to the wing) just to make the plane more stable and to fly slower in the approach to landing. They open according to angle of attack. They don’t have any electric mechanism and open according to air pressure/pressure.

Example:

I have a flight manual somewhere for the Nord version, I’ll see if there is anything written about these 130 km / h.

I’m surprised that you’re asking this, Yoyo.
I have a number of period operation manuals, spare part lists, period promo stuff and what not.
When we made our FSX Bf108 back then I was in close contact with both the owners of D-EBFW and with the Messerschmitt Foundation’s workshop manager. That’s where I got my information, but I thought you know that.

Interesting. So what’s your opinion on the current flight model concerning the points mentioned above?

No, I was convinced that they work the same way as in the Bf-109, but I’m not saying “no” :grin:. Interesting, actually I’ve never heard of slats working like that. It’s even more obvious that the slats need improvement here. What hurts me the most is that they don’t hide at all and I never have a straight wing line.

The principle is the same like any other Handley Page style slot, just aoa is not the trigger for the animation, air pressure/airspeed is the trigger.
Global myth probably over-exaggerates the role of aoa due to stories of unexpectedly popping out Bf109 slats in turn fights.
Anyway, point was that the 108 slats operate much more like on/off. There is no large transitional phase which on the Inibuilds aircraft appears to be roughly between 100 and 150 kph.
The 108 slats are either fully in or out and that happens pretty reliable and predictable at 130 kph on the IRL plane.

Don’t know anything about slats, but I do know prop pitch seems to have no effect on speed. Is that right…?
