FPV flight from yesterday. Much better landing this time. :)

“Caulk and paint makes a carpenter what he ain’t.” A little putty, a little paint and it looks pretty good!

Here is the updated Broadband .stl files. I have not done a test print on it yet, let me know if there needs to be changes.

Thanks,
Jeff

Jeff,
Thanks again for sharing the files. I printed them out but unfortunately, there is a gap along the sides if you if you glue both halves together. I don't think there is enough curvature to the mounting area where the antenna meets the fuselage. I carved a little off of the front and back ends to help and opted to allow for the seam along the top. It'll be easier to fill and sand now. I'm grateful for your contribution and it works for me but just wanted to give you this info incase you wanted to tweak the design a bit. The photo shows the gap after some carving. Prior to, the gap was much larger. Just an FYI.

My 738 FPV flight from today.

Is it possible for someone to post a picture of a really looking AL37? Really getting tired of seeing all these outstanding looking repaints. John Bergsmith , they both look great!

[John Bergsmith]

Ryan and I finally got both AL37’s at the field together yesterday. He put the first two flights on his, both were perfect. Had a blast with these things yesterday.

Here are some static shots of my repaint. This is a rebuild of my crashed United MAX-10. Decided to do this one as a 737-800. 3D printed the winglets from someone who posted them here. I have this one setup as FPV as well but was having some wiring issues so today, I just flew it the old fashioned way today.

Thanks so much! I'll try to print tomorrow if I don't go flying.

I put 4 more flights on my AL37 this morning, what a great flying plane. It really shines doing low slow passes down the runway with half flaps and 30% throttle. Looks very scale in the air.

[Jefferybray]

Would you be willing to post the 3D files here or send out the file in a DM? I have a 3D printer and am interested in the broadband antenna. Thanks.

I will post the .stl file this weekend for broadband antenna.

Hi guys,

still curious about your CG setting?
everybody on the default CG?



grts,

Eric

I only have 3 flights on mine. I had the CG set right at the back of the Mark for the 1st flight and almost stalled on takeoff. I moved the battery forward about 3/4” for the next 2 flights and it flew great and behaved well.
IMO I would not shift the CG aft of the marked location.

My TAROM YR-BGM

[Navy Nugget]

Well while my AL37 arrives I've searched and searched and I have to go with the NAVY P-8A Poseidon scheme, I will modify the winglets easy job since they are removable, more painting than another scheme but no masking involved. Need to place a call to Callie, already have the paint from another warbird so I'm good, maybe add some hard points and some ordnance, thinking maybe parts from the A10 my work...….. .now to wait for the brown truck.

I like that idea!! What color paint are you using for the P8 scheme??

[vduniec]

I didn't like the antennas that were flat and plastic so I 3D printed the antennas and also the broadband antenna. I also printed exhaust cones as well. If anybody is interested in the antennas and exhaust let me know, i will print them and post pictures so you can get an idea.

Would you be willing to post the 3D files here or send out the file in a DM? I have a 3D printer and am interested in the broadband antenna. Thanks.

I put the maiden flights on the AL37, this is the only plane that I have ever flown that was perfectly trimmed from the word go. Never touched the trims. She fly’s great.

[Rudderman98]

Maiden went without a hitch two weeks ago.

No video as of yet. Hopefully soon!

[Rudderman98]

I have my AL37 ready for the maiden. They are calling for 3-4 mph winds tomorrow morning. Throws and CG are set per the manual.

Clear skies and no winds on your maiden!

She's a beauty!!

[themudduck]

Hello,

Getting ready to maiden mine.
just checked the CG, and find that the indicated CG, on top of the wing, is quite conservative....
Does everybody flies on this balance point, or do we move it further back?

My experience on the Avanti is that I could move it more than an inch backwards.
Curious to hear your feedback.



Regards,

Eric

Strange that no one answered you yet... look, the recommended CG on virtually all retail RC products is set too far forward, or "nose heavy" as we usually say. Its like this on purpose because the models are more stable and easier to fly in general, but you should consider it only as a starting point.

Freewing and Flightline are no exception, the CG is too far forward on all of their planes. Some customers like it that way - but the planes are harder to land, they will often bounce and bounce and end up with smashed nose gears. The airliner flies really well but its hard to get the nose up for landing. Most of us here have the battery moved back a bit, so try moving the battery back a little each flight, and see the difference and evaluate according to your preference! Its very forgiving. With the CG moved back, the model will be much easier to flare and you can hold the nose up all the way down the runway. You will also need less "up" trim and takeoffs from grass will be easier.
