Martin XB-51 Cougar

Ladies and Gentlemen, I present the Martin XB-51 "Cougar" attack bomber from the 1950s, complete with rotary bomb bay, working cockpit, variable incidence wing, spoiler roll system, working flaps, slats, trimmable horizontal stab, 9x bombs and 8x 20mm cannon. If you like this build, you can also try out my imagined “B-51B Night Intruder”.

Sorry, this is a 1950s attack jet, so it's fun work to fly well. HINT: Use TRIM...TRIM is your friend!

Credit to @vonhubert for providing much assistance with the sequenced landing gear doors. Please visit his site as he is definitely an underrated builder.

Features and Controls:
AG1 - Nav Lights
AG2 - Reserved
AG3 + VTOL - Flaps and Variable Incidence Wing
AG-4 + VTOL - Speed Brakes
AG-5 + VTOL - Rotary Bomb Bay
AG-6 - Drouge Chute
AG-7 - Reserved
Slats - Retract with Throttle
Roll Spoilers - Roll
TRIM - Well, TRIM, duh!

Flight Manual:

Takeoff: AG3 and VTOL halfway down to lower flaps and variable incidence wing to takeoff setting. Trim nose down (slider up) 1/2 notch, add full power and she'll lift off around 160 mph. Raise flaps and fair the wing by neutralizing the VTOL, add trim as necessary to keep the nose around 10-15 degrees nose up for the climbout. Retract the gear, notice the gear lights extinguish in the cockpit.

Bombing Run: AG-5 plus VTOL full up or down will rotate the bomb bay open. The corresponding green and red lights will illuminate when activating AG-5 and rotating the bomb bay--telling you you're ready to drop. AG-4 plus VTOL down to open the speed brakes and keep your speed under control. Drop bombs using normal controls. 60 degrees nose down works well for aiming...it's all optical dive bombing in this baby...keep enough altitude below you to pull out, as this jet is 40,000+ pounds of streamlined lawn dart on highly loaded wings!

Landing: Lower your landing gear, note the three green “down and locked” lights. Make your approach with flaps and wings set for landing, AG5 + VTOL full down at 160-ish mph and approximately 13% power. USE PLENTY OF NOSE UP (SLIDER DOWN) TRIM. Reduce power to idle coming in over the underrun and flare to settle on the runway. Don't hit too hard, but she lands fairly easily.

    @WarHawk95 yeah, that’s what they called it in that 1950s movie about test flying, “Into the Unknown”, I think it was called. I should remaster this one using Designer Suite and revise the flight model, cause it actually doesn’t fly all that well, very prone to departing controlled flight.

    I was thinking... You should rename it "Gilbert XF-120"
    If you know why you deserve a veteran's discount

    @greasytortle I credit @vonhubert for showing me the basic idea, I simplified it a little by using two stacked rotators, instead of two hinges. The trick is to set one rotator to floppy for part of the retraction, the other covers the necessary rotation to close the doors, plus the floppy rotator’s arc. The shock is there to keep the doors open by pushing for the first part of the rotation until the gear gets partially retracted. The hard part of building this setup is all the fine adjustments necessary to get it to fit together the right way, not to mention trying to get that shock to clip on both ends simultaneously!

    Sequenced gear doors! I just scrap them all together and have my gears merge into the plane. I'm definatly going to look into this though.

    @ChiChiWerx whoah... i had a concept about how to do that but it was hela complex and would require a lot of parts, you've done it with a LOT less parts.
    If i saw this sooner i would have done it on my plane but i've already wasted enough time on those gear doors, i don't wanna waste more time on them,
    i might feature this on my next aircraft,
    Huge thanks!

    @Sauce don’t know if you saw this one or not, sequenced gear doors, might be a help on your F-14...but you probably already figured that out...

    @ChiChiWerx thanks!!!

    BTW, a sneak peak of my new project:
    .
    https://www.simpleplanes.com/a/jWS886/Tupolev-Tu-114-fuselage-0-193
    .
    P.S. the stand is for testing if it tends to roll. Very useful. Spawn at Wright and set wind to 180 degrees and 200 mph. A rotator is in fuselage at CoG.
    .
    P.P.S. Check a new flexible wing)

    @vonhubert the same way as adding screenshots in forum posts, exclamation point, “!” followed by the name of the screenshot in brackets “[]” then the link in parenthesis “()”. Just add the link in the description and it will show the screenshot.
