G7 series Grumman E1B Tracer

[Milton Shupe]

Milton, Eurostar and Tom not sure if you have this in your inventary of documents http://www.alternatewars.com/SAC/E-1..._July_1967.pdf

ps Tom Can you check aircraft length in the air file should be 45ft 4 in and I get a reading of 57ft 11in think that is for the S2F-1/2/3's with the MAD boom extended.

Good observation. Checked it in gmax with the gmax tape measure. It shows the aircraft to be at 13.741 meters or 45'1". Lokks like I came up 2" short. :-) Not bad considering the 3-view lines are 3.5" wide that I model from. :-)

Just FYI, the airplane geometry dimensional parameters are mostly ignored in the aircraft.cfg unless you are using FSEdit to generate the .air file.

A few items corrected: Mostly pitch issues.

The length figure in the cfg file actually has no effect on anything, the model and contact points determine the physical size of the aircraft. Some dimensional items such as positions of engines, size and locations of flying surfaces etc do have an effect on flight charcteristics.

However it should be correct as a reference....

I added the new FDE, but it seems like trim response is very sluggish. The aircraft sort of performs like it is very slowly diverging in pitch and I have to dial in almost the complete opposite trim to counteract it. FYI, I'm using a Saitek X45 for ref.

It also would appear that the cowl flaps do not open and close.

That's my first observation, I'll try more tomorrow.

Still fiddling with the trim. The issue is to have it fast enough, but also fine enough. What repeat setting do you have it on in the FSX settings? One shot, slow or fast? It is essential to be able to have trim unit's small enough to be able to trim level flight. about the only time trim is really too slow is if one re loads the aircraft, which will leave you with several units of nose down trim to roll in.

Things a bit hectic today, daughter who just finished her Instrument rating last week had her baby today! Daughter's name is Skye...

Attached are the model and FM updates for testers. These changes reflect the feedback given so far.

Updates are only the mdl file and aircraft.cfg and .air files.

We will appreciate feedback over the next 24 hours if possible. If all goes well, work will begin on the VC.

Thanks

Anyone else wanting to contribute effort in the beta testing, please contact me.

All we need now is the vc in the Fudd and a good "27 charlie" I.E. Hornet, Kearsarge, Bonnie Dick, etc and I could be back on Yankee Staion! Thanks Milton and crew ! BZ!

Congrats Fliger747 and Skye! Is this the first time you're a grandpa? An instrument rating and a baby at the same time. She's a busy woman.

That seems to explain my experience as well.

Hmm. Interesting. So, remember, all the S-2 variants are slightly divergent in pitch, as they are short-coupled. Trimed up in cruise, if you let go of the yoke, it won't stay put. On the basis of a quick air test from Mugu; at half fuel so I could shoot some circuts, it felt heavier than a stoof, stiffer in yaw, and carries alot of float on round down for landing-79 kts or so. All of which I'd expect from having a big fat wing nailed to the top of a stoof, so if you've modeled that in to the FDE, Good show! If its serendipitous; Good show! I saw no texture or animation issues with a cursory walk around. So, more latter when I've longer than a half hour to play with it.

I added the cockpit model from the S2F-3. The eyepoints in the latest FDE zip are spot on perfect, and the textures are all good so.
1) copy the S2F_interior.mdl file from the G7_S2F3X model folder to the G7_E1BX model folder.
2) open the Model config file. Copy and paste under the the line: normal=E1B
This line: interior=S2F_interior


Okay? Now copy the G7_S2F3X panel folder to the G7_E1BX main folder, save elsewhere or rename the exsisting panel folder.

and I'm guessing the cat points are the same too.
Copy and paste to the aircraft config under the tail hook section:

[launch_assistance]
launch_bar_pivot = 5.41,0.00,-2.0
launch_bar_lug = 11.583333,0.00,-7.50

Very nice! Very nice indeed! It looks not at all like a rough cut. Attachment 70937Attachment 70938

Thanks Laz:

Having a VC for the interim will help test and evaluation quite a bit.

Nice summer day here in middle Alaska, the lady and I flew the cub down to Denali park for a hike followed by dinner at 229, a fabulous restaurant essentially in the middle of nowhere, amazing use of really fresh ingredients! However very windy and bumpy going down, but slightly compensated for by a bit of a t/w coming back.

One item that plagues most FSX planes for deck landing is how seriously pitch forward is modeled. Will have to do some more fiddling in this area as well.

So is it a go to start the VC or do we need a little more time testing?

[Milton Shupe]

I think we are safe to move forward. Any late comments on issues can be picked up during the next phase of test/change/test.
