Albatross!! Albatross!!!

Hello Shane - I read about the prop-reverse in an article of the popular german Aviation Magazine "aerokurier". In the march-issue of this year they have a report about the RedBull operated Albatross of John Schoffner.
They wrote that the Albatross is highly manouverable by the Prop-Reverse
"She can move backwards and turn at the point ......"

Information also available here :

Hope this help a little

Greetings Dirk
 
Here is the entry of the flightreport above :

The Grumman HU-16A Albatross is a high-wing flying boat amphibian. It has a wingspan of 85 feet, a length of 62 feet, and a 22,000 pound empty weight. This ain't your neighbor's Piper Cub!
Propulsion

Power is two nine cylinder two-speed supercharged Wright R-1820-76 radial engines of 1450 horsepower each. Versions of the same engine are used on the T-28 and the B-17. Each engine drives a three-bladed constant speed propeller. Unlike most constant speed propellers, these propellers are electrically controlled and hydraulically actuated independent of engine oil. The governor RPM is set by toggle switches, and the governor and prop hydraulic pump are driven by the engine. A prop oil cooler is integrated into the hub dome. The propeller uses a lighter weight oil than the engine. This system allows immediate control of the propellers on engine start without waiting for the engine oil to warm up. On the water at low speeds, the air rudder is not effective, and no water rudder is installed. The primary means of directional control is differential power. At idle power settings, control is best accomplished by moving one prop in and out of reverse. No beta range was available on these propellers. When the engine is running, the propeller is thrusting one way or the other, so immediate control is necessary.
 
The Albatross' VC is ready for prop reverse; check the overhead:

Thank you for the information folks. I am currently working on implimenting a prop reverse now.

In the meantime, I have the following changes for the contact points. Most of this is driven from your efforts. Can I get some of you to test these changes to verify the fix?

Hello Shane - just back from a short "Testflight" with your modified .cfg-entries - works perfect - start and land without problems. The sreenshots below show
1. Ready for takeoff, 2. short after touchdown, 3. Engines off, 4. Startrun .

Greetings :wavey: Dirk
 
Wow - Henry, i am impressed - has your day more hours than mine ? You are a true "Wizard of the paintbrush"

Thanks for all your last repaints - your Cat`s are great and your Alby looks as she has a lot of more sisters and brothers ....:applause:

Greetings :wavey: Dirk
 
Something different - I have a fictional "Fire-tross" in the works. Maybe with canadian or spanish registration.

Greetings :wavey: Dirk
 
A fictional Alaska State Forestry would be nice in anticipation of Tongass!
 
A little more progress - 6297J, blue and yellow are also very nice, I`ll have a look at the Alaska Forestry one.
 
Wow, Henry - when i see your repaints, i feel a little bit like the young Luke Skywalker during his first meet of Master Yoda. The Student meets his Master. I fly so much Airplanes in Simulation with so much of your repaints and you can surprise me every day...... THANK YOU SO MUCH :applause: :ernae: :jump:.
