Martin Dakilong Ibon

Mb-1/XMB-1

Design and Development
The Mb-1 was a large medium bomber designed by the Dakilong Ibon Aircraft Manufacturing Company with help from the more experienced Glenn L. Martin Company in America. The Mb-1 was built by Dakilong Ibon for the Magling Military.
The aircraft vaguely resembled other bombers of the era because drew inspiration from earlier Martin bombers including the Martin MB-1. The two aircraft also shared virtually the same designation, thus making this article confusing, with only a difference in capitalization being used to distinguish the Martin MB-1 from the Martin-Dakilong Ibon Mb-1.
The frame consisted of welded steel tubes with a covering of aluminum or metal for the nose, lower inner wing, and engine housing and fabric for the rest of the aircraft. The aircraft had electrically powered bomb bay doors powered from the engines.

Although word had been sent well in advance for a requested bomber, the Dakilang Ibon Company only began working on the project a week before the deadline was set because of previous projects and a late partnership with the Martin Company. All other companies were already working on their submission for their requests and some even with help from European companies such as the Luna Company and Presto Aviation who were working with Le Vent and Breguet respectively. All in all, the Mb-1 was sketched & designed in a grand total of fewer than 13 hours and built over a span of 6 days with revisions often being made during the production of the first prototype. The first prototype was designated as the XMB-1, and during a short private testing period, the aircraft was found to be tail heavy with a notable amount of trim required for level flight. This issue along with others such as sluggish controls and handling issues were mostly rectified during the production models but were still present when it was shipped out for government testing. The XMB-1 was delivered fifteen hours before the scheduled deadline.
On a sunny day in the spring of 1925, the aircraft flew out for its first official test flight. The test pilot was alarmed when the XMB-1 started violently pitching upwards but soon found out the necessary amount of trim needed to stabilize the aircraft. In a later test, the XMB-1 was loaded with six 100 lb training bombs. It was found that the bomb bay doors worked perfectly fine, but the bombs could tumble out of the bomb bay leading to a higher standard deviation than expected.
Air Force and Navy staff were wary of the characteristics but ultimately accepted the aircraft.

Despite the XMB-1’s shortcomings, it carried many firsts for the Magaling Military. It was the first in-service aircraft with a fully enclosed bomb bay, an electronic system for the bomb bay, and the first domestic-built twin-engine aircraft.

Controls & Procedure
1. Procedure for take off
2. Set trim at around 50% up, change during flight to stabilize
3. Put throttle at 5%
4. Activate switches 1 & 2 to start the left and right engines
Throttle up
5. Once at 70 mph that aircraft will lift off on its own
6. Once at the desired altitude, adjust trim and decrease throttle to 65-80%

Procedure for landing
1. On final, reduce throttle to 60 percent
2. Once aligned with runway & within a third of the runway, decrease throttle to 30%
3. Once over the runway cut throttle or remain at 5% until touchdown
4. Break and don’t yaw too much

Notes
I drew the basic idea in a class period and built this in four days. It kinda sucks and was stressful to make, but I did incorporate fuselage wings for all the wings and a semi-realistic bomb bay door mechanism. Gone are box wings for now. Hopefully, this makes the deadline
