Official Freewing 80mm EDF L-39 Albatros Thread

[Hardway]

Awesome. When I first read your msg, my brain said 55.00 shipping..... LOL Never mind!!! :Silly:

[seaviper]

Finally had a chance to tear down the motor on the Albatros. It was the front radial bearing that was making noise. I ordered a fresh set of bearings from Boca Bearings.
We'll see if that fixes it. $18.52 shipped vs $55 + shipping for a new motor.

For those that have flown both the Stinger 90 and the L-39 how do they compare?

I'm taking from this thread that with the L-39 flight times are increased, something that definitely appeals to me, and also that the L-39 has a locked-in feel. The Stinger to my mind also has a very locked-in feel so would be interested in your thoughts as to the main flight experience differences between these two.

Thanks
Mike

I've had the Stinger 90, still have the Avanti S and now also the L-39. The S 90 was a superb jet, then it got better with the Avanti S. Now the L-39 is the best one of them all. Flight times are how you make of them and a comparison has little validity from one person to another and from one plane to another and from one flight to another. I can burn through a battery in my Avanti S in less than 2.5 min OR I can make the same plane on the same battery fly for nearly 10 min.

It sounds like it’s simply out of sync. I saw a video that motion put out on how to deal with this. But for the life of me I can’t find it. Maybe someone else can chime in and post the link

Here are the syncing instructions:

L-39 BOARD MCB-E ISSUES?


Posted by Motion RC on November 06, 2018 |

• Category: Tips and Tricks

We have encountered some customers who have been having issues with their L-39 MCB-E control box. The customers who call with problems are connecting everything to the control box and putting the gear down and immediately noticing they can’t steer the front gear. It sounds like the rudder and steering servo are out of sync.

The procedure to put them in sync is the following. Do this with the radio on and battery connected to the ESC of the plane (do not power down plane or radio during tests). For safety, use throttle lock on your radio.

1. Remove steering servo wire from the steering servo port on the MCB-E and connect the steering servo wire to the 2nd rudder port on the MCB-E.
2. Test steering and rudder. Everything should work.
3. Cycle gear up and down 2 – 3 times.
4. Put gear up one last time.
5. Reconnect steering servo to the steering servo port on MCB-E.
6. Test steering with gear up – rudder servo should work, steering servo should not move with the gear up.
7. Put gear down, steering servo should work.

If you have any questions please contact our superb Customer Service team via chat or e-mail Monday through Fridays between 8am and 5pm CST.

Dave, JR XP9303 with the XPS 2.4 module and XPS 6-ch Nano RX. So not Spekky or Futaba. It went into a totally wiped model memory, so I'm at a loss to explain why this was happening.

Felix, I tried everything I could think of, reversing switches, moving plugs, nothing worked. The only solution was to remove rudder/steering from the box and Y them directly to the RX.

[Felixs10]

I tried that too, didn't work. My issue seems to be slightly different in that the rudder/steering works with gear up, but not down. Has to be in my TX/RX somewhere.

Silly question , but did you try reversing the direction of the landing gear channel ?

[dkalwishky]

Pat; which transmitter are you using? Something in the back of my head tells me you're not using Spektrum or Futaba.

I tried moving the plugs into every configuration I could think of. Everything works right when the gear is up, but once deployed rudder and nose steering both stop working. Very odd.

So what arrived today was not the gun pod, but the replacement blue box. It did not solve the issue I'm having where rudder and nose steering only work when the gear is up. I'm now assuming it has something to do with my TX/RX somehow, but for the life of me I cannot figure out why. I have no mixes programmed in that would cause this. I will continue using a Y for those going directly to my RX.

My box does the same thing.... I pulled the nose gear steering and just plugged it into the other rudder servo output. Works fine so far.... Very puzzling... I have no answers at this point...

Mine is scheduled to arrive today.

[Felixs10]

Anyone get there Gun pod yet ? Several pages back, a week or so ago , it was posted that 95 Pcs were/have arriving/arrived. Just curious ..

[TiredIronGRB]

Would one say the L39 is a good first jet?

Yes, if you have good experience with prop planes...it flys better (more solid) than any of my EDFs.

[Petronio]

Awesome! :Cool:

[yf22raptor]

Well we did it the 1st k-30 turbined l 39 ready for maiden
just waiting for good weather here in cali...
expected 6 min flight time JP wheels n brakes..

Just thought I would share a short video of the new Morgan Mill Battery Cartridge system I got, it makes CG a breeze when using different battery sizes. These were both 6s batteries, 4000 mAh and 5000 mAh.
