This is a modification for the MSFS 2020 default Asobo Diamond DV20 aircraft and is primarily aimed at improving the aircraft flight model to make its overall performance more closely match the actual aircraft, providing a much closer experience to flying the real aircraft. Multiple changes have been made to the flight model parameters, and the aircraft weight and balance, which are detailed in the Change Log file included with the download.
The Diamond DV20 is a small easy to fly 2-passenger low wing GA aircraft that provides remarkable performance from only a small 80 Hp Rotax engine. Due to the highly efficient, low drag aerodynamic design of its wings and fuselage it has a top speed of over 120 knots, and a glide ratio of over 14 to 1. It loves to fly, and getting it to slow down and come down again is one of the challenges of learning to operate it correctly.
This mod is easily installed by simply unzipping the download file and copying the mge-asobo-aircraft-dv20 folder to the MSFS Community folder. It will then replace the existing default Diamond DV20 aircraft in the MSFS aircraft selection screen, and will also continue to utilize all of the existing available Liveries. To uninstall the mod and return to using the MSFS default aircraft, simply remove it from the Community folder. This aircraft and this mod are only for the MSFS Deluxe Edition and Premium Deluxe Edition.
STEERING:
This mod uses Free Castering Steering by default to match the real aircraft. To improve the realism and performance of your Toe Brake Pedals, I highly recommend changing the SENSITIVITY settings on the CONTROLS OPTIONS screen to the following...
⦁ Set "SENSITIVITY -" to 33%,
⦁ Set "SENSITIVITY +" to -33%,
⦁ Set "DEAD ZONE" to 0%,
⦁ Set "NEUTRAL" to 60%,
⦁ Set "EXTREMITY DEAD ZONE" to -1%.
This will make the performance of the brakes much closer to the real-world, where the braking force is applied very gradually at first and then increases as the pedal is pressed further down. This will improve the smoothness and realism of braking for all aircraft in MSFS, and it will also make differential brake steering much easier and more precise.

Quick question: Where can I turn on the panel lighting?

If you retract the flaps at the end of the flare out every lift stops and your wheels have full control. If I repeat my standard landing procedure here, I fly again.
In the flare out the stick sensitivity (elevator) seems too high. At the edge of lift the stick becomes LESS sensitive.
The X Cub Red Bull reacts nicely, the Zlin (Savage Grravel) misbehaves the same way. Sensitivity settings stick and authority settings help.
Kind regards from Austria!

Drag of full flaps is quite too low.

Did this mod fixed the bug with the insufficient drag by the flaps?
MGouge425 author
The Flaps LIFT, DRAG and PITCH have all been adjusted by this mod. Please see the Change Log for a detailed list of all of the changes that are included.

Overall good mod, highly suggested, but I believe the author could use the below data to better align the model FD wise.
My background - IRL hours in this plane, (+45hrs)
The plane in sim is rated at 80HP by the CFG files, which I can not find on Diamonds docs, and most DV20 are 125HP, with some being 100HP for the Rotax engine, neither of which is model correctly at the rated 80HP in the game, where even the cylinder_displacement is wrong, not sure where MS got some of these numbers.
According to POH, section (based on the IO-240B 125HP)
Based on the DV20 AMM with the Continental Motors IO-240B (125HP) it has the following engine details, where the SIM default is badly under powered @80HP:
Based on the DV20C1 POH Wing details are the following :
I think the :
Htail, and Vtail calculation appear to be ok based on the POH for the DA20 thus far.
Drag (Flaps)
Closely follow the DA40NGx mode, and are +.5 more, so if anything the DA20 mod, will have a bit more drag, which is better for feel and training.

Thanks for this great detailed feedback...
Apparently, there must be more than one version of the DV20 with different engine sizes. The engine and airframe specs I used for the mod are from the Diamond DV20 AFM, which is included in the download under the DOCUMENTATION folder. This AFM specifies the 80 HP Rotax 912 A3 engine.
I'll take a look at the other specs you provided, and see if I need to make any further adjustments to the flight model.

So, finally, I was able to take version 1.2.0 for an outing around the home field. The additional panel light and the adjusted prop lever are great! Now I have to find out how to change my prior rating to the more appropriate five stars. 😊

Thanks for all your tweaks to aircraft - you add greatly to my enjoyment of the sim.

Thx for all your realism mods! I really like them and have installed nearly all of them.
Do you also plan to create a realism mod for the Beech G36 Bonanza?
MGouge425 author
Thanks... I am not currently planning to do a mod for the G36 because there is already one available that seems to have very high user ratings.

I know it might not be realistic but is there any way to get some backlighting on the instruments, everything is pitch black at night unless you use the torch.
MGouge425 author
I agree... I'll take a look at adding some cabin lights or panel lights. Unfortunately, the POH does not describe the internal lighting in the real aircraft, so it might not have any. Maybe @peacemaker0079 can tell us what lighting the real aircraft has, if any?

A forgotten little airplane who deserve attention. Thanks for this great mod and thanks to peacemaker0079 for the torough real world input.

Tip of the Day: This aircraft has a very efficient low drag wing and fuselage, and a much higher than usual glide ratio of 14 to 1, so it can be very difficult, or impossible, to perform a steep glideslope descent greater than 3 or 4 degrees. So, you should avoid making a high approach, and make sure your final approach altitude and airspeed have been established well in advance of reaching your glideslope descent point. The final approach speed should be about 60 knots with full flaps, at an approach altitude of about 1000 ft. AGL. Begin your descent as soon as the runway VASI/PAPI lights start changing from red to white. A standard 3-degree glideslope descent at 60 knots is about -300 fpm.
Also, don't forget to apply Carb Heat, which will further reduce your idle power and increase your descent rate a little bit more. You can also perform a sideslip to lose some altitude if needed.
