There's a new Dragon in the skys [Released to SOH 18 Sep 21]

Interesting story. VH-UTV is owned by a Doctor Roy Fox (or last I heard). Being a urologist he owned several vintage aircraft all with registrations related to urinary problems. UTV was related to Urinary Tract Virus and another he owned was registered VH-UTI for Urinary Tract Infection.

Fascinating. I hope he also had a plane registered VH-PPP.

It's listed as version 1, but when you download and extract the zip file the folder is named MSFS_Rapide_v1.1.
 
Beautiful work, Dave. Great to have this back in my hangar.

Can I have some advice about where to set the CG? In the weight and balance screen, the permitted CG range currently is set to be from 0% to 100% of mean aerodynamic chord (unlikely) and the empty CG is at 5.9% of MAC (also unlikely). But I know that these values are often meaningless in MSFS. Do you recommend that we just leave the starting CG where it is, or slide it back to something plausible like 25% MAC, or ??? The plane seems to require some up elevator trim to stay level in cruise with the default CG.

Thanks for the great plane!

I've re-set the CG to MSFS specs in mine so that I don't have to adjust anything on screen:

empty_weight_CG_position = -1.45, 0, 0
CG_forward_limit =0.12
CG_aft_limit =0.33

I've also changed the load to help with this, and the nose-over when braking:

max_number_of_stations =8

station_load.0 = 170, 5.8, 0.0, 1, TT:MENU.PAYLOAD.PILOT, 1
station_load.1 = 170, 3.2, 1.3, 1, TT:MENU.PAYLOAD.PASSENGER_01, 3
station_load.2 = 170, 3.2, -1.3, 1, TT:MENU.PAYLOAD.PASSENGER_02, 3
station_load.3 = 170, 0.7, 1.3, 1, TT:MENU.PAYLOAD.PASSENGER_03, 3
station_load.4 = 170, 0.7, -1.3, 1, TT:MENU.PAYLOAD.PASSENGER_04, 3
station_load.5 = 170, -1.8, 1.3, 1, TT:MENU.PAYLOAD.PASSENGER_05, 3
station_load.6 = 170, -1.8, -1.3, 1, TT:MENU.PAYLOAD.PASSENGER_06, 3
station_load.7 = 85, -3.3, 0.0, 1, TT:MENU.PAYLOAD.BAGGAGE_01, 6

This gives a slightly rearward CG so you can use the brakes with confidence, but you could still move the slider on screen if you want a central or forward CG.

Edit: One other adjustment you may want to make is to the static pitch - in the opening videos when you click "Fly" the tail is up in the air - I've managed to fix this so that it's on the ground even when you press "Y" for slew mode:

static_pitch = 15
static_cg_height = 5.3

There's also an error in the max number of contact points, which should be 12:

max_number_of_points = 12

The last 2 points are Class 17, whatever that is? I only know of 5 classes from FSX/FS9.
 
I forgot about the Oil Pressure gauges which are reading very low - normal is 70 according to the placard next to them. In the engines.cfg, [PISTON_ENGINE] section, look for the oil_press_max line and change it to this:

oil_press_max=11837
 
Thank you Dave, you've created a superb model which is well worth the time and effort - actually it's been great fun and very interesting, who am I kidding? :p
 
Thanks Tiger, I sometimes mess around with those CG values in the cfg myself, and I appreciate you sharing your parameters. I will give them a try.

Couple more things I just noticed about the contact points. There is no point.9, so there are only 11 points. I don't know what happens when you number the contact points non-consecutively.

The two points with type "17" (I've not seen that either; the SDK defines "16" as the new contact point type for skis, but I've wondered if that is really supposed to be "6") are in a strange position, just inboard of the landing gear and at a height of around the lower wing or something. Hard to imagine them ever touching the ground, so I've commented them out. Not sure they are even intended to be there, they might be a vestige of some donor CFG file. Dave's max_number_of_points probably should stay set to 9. (There were only 9 contact points in the FSX/P3D version.)

Well spotted, August, thank you - I've done the same with mine now.
 
I think those last 2 entries were left over from when I was playing about with the SDK sample DA62. Obviously should have been removed, sorry about that. I'll update my source files, and add in the improvements mentioned in this thread.
