Official Freewing 80mm EDF L-39 Albatros Thread

[Evan D]

Congrats Rudder and Race, The more you fly it the more you'll like it. Not only is it stable but it's also highly aerobatic... It just has no issues.

[Hardway]

Welcome Rudder! Glad you are here!!! Have a blessed Sunday!!! Jerry

Pull the esc programming instructions from Motion and go through the complete option settings. Ask me how I know........I used the same radio profile as my Avanti and getting 4.5mins on 6250ma. I set time to 3:45 on the L39 using 5000ma. First few flights were less than 2.5 and hitting LVC. I went through and reprogrammed the esc using the throttle stick and now I'm back at 4.5 mins on this jet even with a 5000ma bat.
As for throttle range set, yes for sure initial and rebind then you should be set.

Yup!

4.5 minutes on a 6S 5000 with proper throttle calibration.

I agree with Evan D's assessment. The F-86 feels lighter on the wing, which is good in some respects and not in others. The L-39 "penetrates" better through wider wind conditions. It feels very locked in, which is typical of a model carrying a bit more speed and a bit higher wing loading. If you're comfortable with your F-86, I don't think you'd have any problem acclimating to the L-39. They're similar enough to where it won't feel like you're jumping a chasm in difficulty, yet they're still different enough where flying them back to back offers something unique for both.

The real advantage the L-39 has, in my opinion, is the undercarriage as Evan D pointed out. The L-39 has larger and stronger undercarriage, and it still has a respectably slow and controllable approach speed, so all that suspension is just extra insurance. My F-86 had a tendency to hop if I didn't pin her down correctly. The L-39 tends to soak up my bad landings better, and its wheels are larger which is always an advantage of plowing through grass or riverbed or whatever I can fly off of here.

Ditto that comment.

Just maidened mine today and it was rock solid from the get go! I immediately felt comfortable with this plane as opposed to other EDF's I have flown. I have the Admiral 6ch Rx with gyro and where I fly it seems to be always windy and she handled the wind like it wasn't there.

Yup! My F-86 did the bunny hop a few weeks ago and luckily she came out unscathed (whew)!

The L-39 is my "go to" plane.

2 flights on mine today. Wind was finally down the runway and not a 90 degree crosswind. Had to relearn how not to hold in rudder. Hehe.

[Race 22 Crew]

Hummmmmmm 🤔

[Ron1950]

actually it was almost zero power with the gear down and takeoff flaps all ready deployed,,,hope it doesent do that again :)

[Race 22 Crew]

Deployed at a higher speed probably.

[Ron1950]

my l39 has been flying fine until yesterday when I dropped the flaps to full the nose went up about 45 degrees... never did that before so checked the flap to elevator mix and reduced it quit a bit...it worked at that setting well until now one of those things that make u go hummmmm!!!

[Deegeedoo]

Has anyone here got a near match for the Red colour for the L-39?? TIA

Hi Guys,
Just in case anyone else has to replace one of the elevator servos, this is some of my notes based on my experience.

1] remove the vertical fin 4 screws
2] remove the horizonal stub 4 screws
3 unplug both elevator servo plugs
4] pull out servos leads with horizontal stub
5] the servo is mounted in the pocket with silicone glue.
6] use an xacto knife to cut the glue around the edges of the servo
7] I used my spudger tool to clean the glue without hurting the foam
8] use needle nosed pliers to lift out the servo with the pliers (see photo)
9] please note: the servo lead is 30" and not what the L39 product page says.
10] reverse the process to install the new servo. Use silicone glue to mount the new servo and feed the lead into the foam channel and route it back through the stub opening.
I hope this helps

[RichJ53]

Flew my L39 today and thanks Scott H for the flight photos!! I just before taxing out on my next flight, I noticed my left elevator servo wasn't moving :(….. aborted my flight and later at home it looks like another bad servo. Yikes... that was a close one.

[Ron1950]

nice one bill know that feeling of which vid to use lol at least you have a long runway we land on 280 feet but its kinda rough and always a crosswind so u have to hit first 50 feet or its in the grass lol

Decided to try and get some video of my Arctic Aggressor repaint today since I didn't get any yesterday while doing the F-18 maiden. I only took two batteries along so I'd leave the field earlier in the day as well. Yesterday about killed me staying til noon. I was on my way back home before 10:00 this morning and as a result, don't feel as dead. I was flying a bit on the aggressive side for this video and tracking left a bit to be desired. I didn't allow quite enough weight shift for the flight pack to compensate for the extra weight of the tag and was a little nose heavy as well.

https://youtu.be/7VN7s1yEoQ4

I wasn't flying as aggressively on this flight as I did during the "Arctic 1" and the Soloshot tracking worked pretty good overall. Even if it hadn't this would have been my "keeper video" just for the landing. It's not often that I make a nice smooth one, and even more rare is for it to be caught on video.

Hi
I just picked up the camo model and do not have access to a 3d Printed, can someone please share a place to purchase the 3D interior cockpit parts already printed ?
Thank you

Is a 50c rated pack enough, or should I look for something a bit higher? I know a lot of people are using the Admiral 5000 mAh 50c batteries, I would even consider a 6000 mAh battery since there is so much room in the battery bay, and the flight times would go up from around 3 1/2 minutes to over 4 minutes I would think?
Thanks in advance for any additional help.

I run the Admiral 5000 40C, Admiral Carbon 5100 70C and the Roaring Top 6250 35C with no issues at all...but you can tell the Carbon has more punch.

Just finished the maiden and 4 more flights, what a great flying plane! The only thing I will comment on is the roll out, I fly off of a paved 700 foot runway, and once I touch down it almost takes the full length to stop, even if I set down at the very beginning. I am using flaps and come in fairly slow.
Has anyone found a way to put some sort braking device on the main wheels, I was thinking of some type of "O" ring on the axle to rub a bit on the wheel hub and the landing gear strut, other than actual brakes I don't know of a way.
Any additional help would be greatly appreciated.

Funny you should comment on this.... I thought it just my L39. If you can get it slow just before touchdown and not to nose heavy helps :)
I purchased these to add onto my L39 but have not installed them yet. Direct replacement for the stock wheels and tires 4mm axle will run off the 6S pack with a adaptor

"The JP Hobby Electromagnetic Control Aircraft Braking System is the easiest to use and most reliable aircraft braking system available. It replaces the old style pneumatic and servo applied remote control braking systems. This design allows for easier installation and better control of braking. High grade aluminum construction with ball bearing wheels and replaceable hollow rubber tires. input Voltage: 7.2 - 30 Volts
NOTE: these are the NEW VERSION control boards. The braking force is now controlled by the servo travel/endpoints you set in your TX. The brakes can set a 2 or 3 position switch.

great guys to work with

Hmmmm ........................... I've never messed with stock programming unless the plane performs oddly. So far, using the settings as they come, have been quite satisfactory for me, so I don't want to risk screwing something up, which I fear I'm likely to do delving into stuff I know very little about. The only time I fiddled with the programming was when I transplanted components into a different plane and quite frankly, I couldn't tell the difference in the way the plane performed no matter what settings I chose. Instructions I've read on some ESCs I have, have indicated that "med" or "auto" is sufficient for general applications. Sports cars, I tweak. Model planes, I usually leave it as is.

You can’t Dork the timing unless you set it on HighLOLWith low timing you’re running the fan more efficiently & not wasting output as extra heat..Tweaking Edfs I love :)

[CFIT rob]

Just swapped the fan for an fms 2000kv inrunner from horizon(2100kv direct from fms on backorder). Flight times went from 3:30 with 3.8v to 3.77v per cell remaining to 5 min with same volt per cell avg. Better vertical,slightly shorter take off (doesnt seem much faster though) Quieter than stock but still has a nice jet "woosh" sound.I got similar results with the same swap in my mig 21. Im sold on inrunners.
