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

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

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.

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.

[Hugh Wiedman]

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!

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.

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

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

Thanks for letting me know, I'll create more of a curvature, looking at the pictures I see what you are saying.

That was fun to watch, great POV. I like the way the light changed inside the cockpit.

Ok,

maidened mine today, with the CG as indicated.
During the take off roll, it became obvious that the CG was way to much fwd.
It was such that I had no more elevator to flair during the landing.
Apart from that, it was a successful maiden flight on the 737 today



have a nice one,

Eric

That is a beautiful job on your plane!! Its stunning!

The marked CG on virtually all FW planes is too far forward, its a "starting point" and virtually all of us prefer to move the CG back. "How far back" depends a lot on what you like in terms of the model's performance. For the AL37, try moving the battery back 5mm on each flight until you like it. Don't go back further than that!

I took an airborne video with my AL37 today. It was quite windy, made all the passengers very sick. But I made a perfect landing on one wheel, then the other one!!

Sparky and I were able to share the skies together at our club fun fly this week end....pretty cool airshow

Hi Scale Freak,

what battery capacity are you flying?
They indicate a 10min flight time on a 5000mAh package🤔



Regards,

Eric

I have 6S 5000 mAh batteries. I am finding that with better throttle management, I am getting up to 4 min with around 35% battery left. I cant see how you would get 10min flight times, so if anyone is please tell me how! I am considering 6000 mAh batteries next to extend the time available.

A 10 min flight, even on 6000s, would require very careful throttle management including a partial throttle take-off and slow flying.

Remember - Long flight times may equate to the following:
- Long recharge times
- Reduced battery life
- Not having a safety net at the end if a go-around is necessary
- Increased chance of battery puffing
- Increased chance of going below the 3.3V minimum battery voltage
- Hot battery... and heat is a LiPo killer
- ESC low-voltage motor shut-down

Shorter flight times allow for a more flexible throttle management with some acrobatics and fast passes.
Target a flight time and style that leaves about 3.7 V cell voltage. Safer and your batteries will love you for it.

Hi All,

I'm loving all the paint schemes on this AL37, I'm just in the finishing stages of my own (which I will post soon).

Just curious what sort of clear coat sheen levels are people using? Matt, Satin, Semi-Gloss or Gloss?

Cheers Darius
