Did testing on the drag ratios (used a 12000ft runway as a benchmark). After adjustments to the gear drag we now have:
These updates will be in the next release.
I tested the fuel flow, when I follow JMB specs:
FL95
3.7gph 125KTAS (4300RPM)
4.7gph 146KTAS (4800RPM)
9.7gph 186KTAS (5500RPM)
And adjust RPM accordingly, itâs perfect. Only if you leave the engine at 5800RPM are the numbers too high.
Itâs the engine RPM.. the prop is around 2500ish rpm.
Oh yeah my bad sorryâŠengine RPM. I adjusted the post accordingly. The gear ratio is factory spec so should take care of the prop speed. Thank you 
No problem 
But if the prop spinned at 5800rpm at 5.7feet diameter it would go alsmost twice the speed of sound ^^ I think the prop rpm isnât displayed anywhere with a rotax constant speed.
Good thing we are actually accurately simulating the prop as well (min/max angles, size, etc). We did our homework
Late to the party. This was my favourite aircraft in MSFS so far and Iâve made several videos with it. Iâm a real world pilot and test pilot of experimental aircraft so Iâll give this a try and see how it feels. Reading through the posts it seems youâve done an awesome job so Iâm looking forward to evaluating the handling and performance. Iâll record it as a first impression and discuss the considerations from a flight test perspective.
A test pilot for experimentals⊠Thatâs what MSFS needed great!
Wow that is awesomeâŠa real test pilot for this plane (and for experimentals / UL some more), we are honored! Definitely looking forward to your impressions. If youâre going to test using our latest build (0.10), you may want to adjust the flight_model.cfg section, at least until our next release comes out.
drag_coef_flaps = 0.12000
drag_coef_gear = 0.03000
This will adjust drag to recreate observed glide ratios.
Ok so there was too much drag with the gear down? 17 to 9 is already huge!
I received an email notification where you were saying that the glide ratios were good but it looks like you changed your mind? Thank you for your hard work
Ah the glide ratio for clean was perfect, for gear down needed work. All fixed now, youâll have it all in the next release.
If you canât wait, simply make these changes in the flight_model.cfg yourself :
Will try when I have some time. Thanks 
It felt almost like a Twin Otter with full flaps lol.
Thanks @tchitkom, much appreciated
Iâm glad this plane receive so much love from the community and that real pilots are getting involved =)
Hi all.
Donât know if someone interested but I have hadded an âeffectsâ folder in the 915âs one to have better landing light.
In this folder i have pasted the âLIGHT_Asobo_Landing.fxâ from âC:\Users\username\AppData\Local\Packages\Microsoft.FlightSimulator_8wekyb3d8bbwe\LocalCache\Packages\Official\OneStore\fs-base-effects\effectsâ folder and have edited it to have LEDs lightning with a bit more power before rename it. (see above).
It seems fonctionnal withâŠ

If someone want to try, I prefer this landing light personnaly
Marcel Dassault said true words ⊠A beautiful plane is a plane flying very well ! ⊠And your VL-3 is a veryyyyyy beautiful one 
PS: Remember to declare the new âLIGHT_VL3_Landing.fxâ (I named it like that) in the âlayout.jsonâ 
You know this mod? Uwaâs lighting mods | Updated aircraft lighting for Microsoft Flight Simulator 2020
Already requested to the author, the mod for the VL3, can you send him the required config?
Hi thanks for this great mod its a treat to fly.
I noticed that the RPM meter is constantly in the red/yellow 5700- 5800+ . Probably just a meter coloration thing.
Probably cause Asoboâs rotax modelling is broken. You can use the dial or âpropâ rpm to turn it down. Max continuous is 5500rpm. I usually run 5400rpmâŠcause Iâm not paying for fuel haha!
thanx mate for the quick answer. did not the the dial ^^
Proposed Changes:
On file systems.cfg
from
lightdef.4 = Type:5#...#LocalRotation:0,0,0#...
to
lightdef.4 = Type:5#...#LocalRotation:-10,0,0#...
result, it angles the landing light a little upwards (10 degrees), so you can actually see whats is in front and below your aircraft, not only below.
Bugfix, on systems.cfg
from
lightdef.5 = Type:2#....#EffectFile:LIGHT_ASOBO_StrobeSimple#...
to
lightdef.5 = Type:2#...#EffectFile:LIGHT_ASOBO_StrobeTop#...
Is the tail strobe light, on the default VL3 is bad, on the external view, you can only see it on the front 180degrees of front part of the aircraft, not on from behind, that change makes the top tail strobe to a omnidirectional light, like in reality
