Useful for making wings and control surfaces out of fuselages and DIY steering. Makes the input controlled by the Roll (A/D) control surface. Makes the input controlled by engine throttle. Remember: Activation groups are completely different to inputs Such as setting a rotator to be controlled using landing gear. Parts that have inputs such as rotators, lights, and engines, ect, Can be XMLed to be controlled by a specific input. NOTE: add the Masscale, Scale or disable collisions input right after the materials in the XML text. Hidden by default.įor tags that are hidden by default, you have to type them in like this: If true, part will pass through other parts. Some parts, like Fuselage Blocks only have one, but most engines have three.Ĭhange the size of parts for more detail or lower part count. Don't change it, it is automatically reset upon loading the aircraft. xml file.Īmount of air resistance each part gives, for calculating drag points. Like position, use a mod to edit this instead of the. Rotation around each individual axis in degrees. Try using a mod like FineTuner to move it to exact locations instead of editing the. Internal part name, useful for obtaining Removed Parts Don't change it! It is useful for making new or removing attach points. "FFFFFFFF" is White.ĭefines the part number. Others such as "exhaustStartColorOverridePrimary" work on a colour code. X is to lateral scale as Y is to vertical, Z being the length. ![]() Values like "exhaustScale" (default 1,1,1) work on a X,Y,Z format. Decimals like 2.5 can also be used to get a more accurate power scale. Such as changing the default value (1) to 2, doubles the engine power, as 3 triples it. ![]() This particular one scales only the engine power of an engine on a multiplication scale. With using a text editor on an ".xml" file, physics and logic for parts can be changed, such as editing the "powerMultiplier" tag on an engine. It is useful for those are starting to Mod and Edit their own creations or other users creations. XML Modding has its own Modding Guide on Reddit. XML Modding includes editing a certain block or propeller, etc. You can help SimplePlanes Wiki by expanding it. ![]() 50 in (12.7 mm) Browning M2 machine guns in remote controlled turrets Powerplant: 4 × Allison V-3420-11 liquid-cooled W24 (double-vee) engines, 2,100 hp (1,600 kW) each.Crew: 10: pilot, co-pilot, flight engineer, bombardier, navigator, radio operator, side gunners (two), top gunner, and tail gunner.However, the B-39 program was by now seriously delayed, and the flawed R-3350 B-29s had already been rushed into combat in June 1944.ĭespite continuing problems with the B-29s, the aircraft was functioning well enough in combat that it no longer made any sense to shift resources in the manufacturing base to a new engine for the B-29 and so the B-39 was not ordered into production. The initial flight tests of the B-39, without turbosuperchargers installed, were impressive. The first flight of the B-39 was made on 9 December 1944 at Cleveland, Ohio. General Motors modified B-29 to use Allison V-3420 enginesįisher finally focused again on the B-39. However, in October 1944, for a variety of reasons, the P-75 was canceled. In June 1944, Fisher received a contract for 2,500 P-75s. Army Air Force that it required a long range air superiority fighter, Fisher was directed to focus on its other major project, the P-75 Eagle. In addition, in early 1944, due to a sudden realization from the U.S. Other turbosuperchargers were considered, but the end result was that the first flights of the B-39 had to be made without any turbosuperchargers at all. Testing on it began in early 1944.įurther development of the engine and the aircraft was delayed by a series of changes in the planned turbosuperchargers as the originally specified GE Type CM-2 two-stage turbosupercharger became unavailable due to demands on GE's production of its other turbosuperchargers. Fisher was chosen for the modification as it was familiar with the engine, as it was to power the P-75 Eagle that they were then developing. Starting life as the first YB-29 delivered to the United States Army Air Forces, it was sent in November 1943 to the Fisher Body Aircraft Development Section of General Motors to be converted to use Allison V-3420-17 liquid-cooled W24 (twin-V12, common crankcase) inline engines. ![]()
