To help out Alpha since he's always so busy designing, building, manufacturing, planning, writing poetry and calling all their customers of his fantastic products, I thought I'd give him a short break and help you out. Just look under "upgrades" on the website, 3D parts, in the tab next to spare parts for the B-24. This, like the F-4, are ones that Motion still offers.

I tried that-i can only find a kitset of Pre-Printed parts. The only STL files i found anywhere were a pair of nosegear doors!

Hey Alpha are these 3D printing files still available for free download and if so can you point me to where i can download them please mate👍Cheers

The pre-printed sets are on order, friends. We're not doing a pre-order on them; they'll be uploaded to the website when their container arrives (multiple inbound so I can't say definitively when it will arrive exactly). **EDIT** I spoke with Freewing and the B-24 pre-printed sets shipped earlier this month.

The free printable files were posted on this thread in December.

I totally agree that the swing style doors are the simple way to go. I think if you did make them roller style they would have to be on some sort of trigger spring that would pull them open fast. Probably wouldn't be able to close them with the radio. Almost like a trap door. Set by hand and activated by a servo pin release.

Isn't frustrating not being able to hit anything with your rookie bombardiers?

That's an interesting idea. But I notice that I only open them when one a bombing run, and at that point nobody can actually see what type of door it is. So the swing type works fine. I would be concerned with something that doesn't close. I've flown a couple planes with open bays (in one case a Hangar-9 B-25 where the battery hatch accidentally fell off, exposing an area approximately corresponding to the bomb bay), and they did not fly well. The back of the plane is like a giant parachute. It works for straight and level flight, but landing that way adds another challenge.

I don't mind errant bombs, I 3D print them so they are pretty expendable. It is kind of funny when somebody drops them wildly off target, or drops the bomb before opening the door, so they come tumbling out when the door opens.

Yes, I did, but I cheated - I have B-17 style doors that swing open on hinges. That makes it pretty easy. I am in progress on a VQ 110" B-24 with proper sliding doors. My advice is - skip the sliding doors. Nobody will notice, and it is about 100x harder than everything else on the model.

It's been a while, but if I recall I have a carbon rod down the spine to make up for the loss of belly strength (too lazy to go look...it's hanging from garage roof). Anyway I haven't had any structural problems.

By the way, on my foam B-24, I put two receivers in it, and so a second transmitter controls turrets, flaps, gear, bomb bay doors, and bomb drop. That way I can give it to a person with no flying experience, and they can participate as bombardier. There are always somebody's kids or grandkids hanging around the field, and they love being able to do this. Of course I lose a lot of bombs that way .

We had a bomber day at the field. I had forgotten how nice it is to fly the B24. Anyway, me and my buddies lumbered around in formation and had a great time.

I have several 4s 5000mah Thunder Power Pro lite batteries. Has anyone run larger than the 3000-4000 recommended batteries? These batteries are 465 grams each and Dimensions (mm) are: 37 x 43 x 136. Thanks!

[Gringotuerto]

has anyone made this model with a working bomb bay with the ability to drop?

The book says to mix down elevator with flaps. She will balloon otherwise when you deploy the flaps.

[John Bergsmith]

Book does say to set it up that way. I then read one of the posts saying they had to put down trim when flying.

Interesting, I didn't read that. Guess I'm glad I didn't because I had to trim down a little bit. It sure does fly good.

[John Bergsmith]

Just asking. Did you set the elevator one eighth up. I was wondering if anyone flew it that way.

I don’t think I set mine like that, does it say to do that in the book? Mine are about 3/32 down after first flight.

[John Bergsmith]

John, I am right with you, I fly mine with 3600's and its still way overpowered and has plenty of duration. I think my timer is set for 12 minutes and I rarely come close to using most of the battery. I haven't tried but I think it would probably fly OK with a 2-cell! Multi-engine planes with long wings do like rudder - on mine I have it permanently mixed in. The only problem I've had is that somehow I lost the wing spars last week and had to order a new set! (I looked everywhere, I know that the original ones must be around somewhere...)

And I agree 100%, I think a big B29 from Flightline would be a real home run.

I keep my wing tubes inside the fuselage, or else I would be forgetting them for sure!

Flew my B-24, Male Call, yesterday and I’m impressed. I flew it on two 3s 4200’s for five minutes and landed with plenty of battery. The power 3s provides is way mite than enough. I flew at a little less than half for most of the flight. I balanced per the manual, it required some down trim. It seems to like a little rudder combined with the ailerons in the turns, I expected that. Takeoffs and landings were no issue.

I can’t wait to fly again! Now where is the B-17 and or B-29?

Spad Driver like the Black and red livery. The led bulb is a nice touch also. you will love how nice it flies.

[Spad Driver]

Got myself a B-24!.
picked up an olive liberator and am thinking of converting it to a PBY-1 like this. Have found a LED bulb that makes a great philco turret.

Here are a couple pictures my brother got of my B-24 liberator doing low fly by's
