Nice work TLewis!

All,

I have attached a link to our club website.

If you scroll down to "Of Interest", you'll find a very nice tribute to my friend's father who was a flight engineer on B24s in Europe.

Hand written notes and pix, also:

Thanks for posting. Great story. I wish I had asked more questions of my dad as well. Even better, have him write some of it down. Amazing how many engine outs your dad experienced. I thought the B-24 was suppose to be really tough to fly with out one motor and he had a two out situation a few times and landed. Also, the amount of hung bombs was eye opening too.

[marwady]

Yes, I was a bit surprised to understand how much mechanical issues hampered these missions.

Dealing with that along with the Germans trying to kill you makes these men even more heroic.

I finally got my second B-24 flying, complete with a photoshoot from my friend Dylan Phelps.

[Detchman]

Beautiful! Hope to get my first one maidened this month.

Took some reference pictures from the full size bird at the Wright Patt Air Force Museum.

TLewis95 incredible photos and a terrific looking B-24. Congratulations, you did a spectacular job!

Here's mine. Great scheme.

Looks good. Lot of work on those panel lines and oil spray.

Hey Mike, didn't your B-24 make it last year in the final 64 March Mayhem? Seem to remember it and thinking what a great looking B-24!

Well, you should have, akways next year!

Alpha how about another ALPHA MAKES session and lets knock out a BombBay Cassette

combination of flat panel slide and clam shell doors for a faux articulated garage door setup.

One servo to open/close doors, and one servo (or eflite bomb release) to activate the bomb drop

My thoughts are a faux garage door. 2 Vertical Doors to simulate the doors rolling up the outside. use a connecting point like on integrated hinges on landing gear doors to slide within a channel up the side, then 2 clam shell doors to simulate the rolling open on the bottom. Probably need an off-set hinge point on the clams so the arc is more internal than outside the fuselage side. Connection to the side door by pushrod would slide it open and provide relief for clam shell to stow upward. Then lower into closed position when servo closes bay.

One servo operates the doors. A second servo (or eflite bomb release) would be used to release the bombs. basically use a rubber band attached to the cassette roof, holding bombs to bomb rails, connected to the release mechanism.

glue a piece of light plywood on the fuselage ceiling, then you could screw in the cassette and it would be easily removable for servo/mechanism maintenance if required. With Cassette attached, structural integrity should be unaffected. may be fore/aft attachment point on vertical walls as well.

Now if i only had skill and experience to draw in Fusion or other CAD and test movement of the operation

Can someone run a test for me?

I got my B-24 motors working but they have a really odd behavior. If I plug in just the battery with the BEC the RX works fine but no response from the ESCs at all. Then when I plug the 2nd battery in, all 4 speed controls arm and work fine. Now here's the weird part: if I have the motors running and I unplug the non-BEC battery, those motors shut down immediately since they have no power.

BUT within a few seconds, the other motors ramp down and start beeping like they have no throttle signal! How the heck are they wired for that to happen? I would have thought they all see the throttle signal and power is to each pair. Obviously something else is in the throttle signal pathway???

This is already on Thingverse.

Here's my take on the way forward with the bomb bay:

First off buy some retro cap bombs off eBay and modify slightly:

Cut open the "first bomb compartment" on the B-24 and make up some balsa doors to add:

Add a control circuit (from Daves R C Electronics - operates doors and drops bombs from a single channel using a 3-way switch on your TX):

Make up a balsa structure to fit inside the cut open bay to strengthen the fuselage and mount E-Flite Payload Release Mechanisms and door servos:



Clip in the bombs:


Test it all works (4 bombs can be released singly, all together, all together with a one second delay between each or in pairs):

Add tail lights for good measure (white light illuminates when bomb doors are open - the second light is red and operates when bombs are dropping but didn't stay on long enough for me to get a photo' !):



It all sits close to the C/G and the 'plane balances OK (with a small video camera in the nose turret). It's not scale but it's fun :D

[Hugh Wiedman]

Mikdys I LIKE IT! Well done!

Tried out the bomb bay mods at the field today - all went well part from my bombing accuracy! Here's some video from the front turret:

Mike, are you flying from an abandoned WWII airfield in England? Sure looks the part....
