Hey people how sturdy or rather how likely is the Albatros to develop slop on the front strut over time? My A4 has a lot!! A friend of mine and myself just got the bird and am wondering if it is worth to design one of those nose strut support brace that someone else had designed for the Avanti...? Tx!

Like all trike gear planes, they will over time start to get sloppy. A lot depends on how you grease it in on mains and keep shock load off nose wheel. That being said, my landings are not always perfect, so I had a friend make the support for my Avanti and the extra one I modified to fit my L-39. It takes a little bit of trimming, as the two planes are slightly different. But I like the added support the brace gives the front strut when it is extended. So I believe it can only help out for those less then perfect landings.

It was already done. ;)

L-39 Nose Gear Brace by bettsmums

This part will help support the nose wheel retract when it is extended. I used the rubber cement that came with the plane kit to glue it in place. Make sure that it sits about 1mm below the top of the retract bay to allow room for the nose gear door to close. It is best to install it when the plane is new. If you are installing it in an older plane that has fore and aft play make sure that it is installed flush with the back wall of the retract bay. If you push a worn retract forward it will change the caster angle and cause the ground handling to be questionable. There will be still be play moving forward on a worn retract.

I've already printed one and installed it. Works perfectly!

Hello,
short update refering to my L39: Talked to MRC EU, which was a pleasure for me.
They offered me a new plane, but after figuring out these and that we came to the conclusion that I'll get a new main gear and new tip tanks.
That's fine for me so I can continue with assembling. :Cool:
Already painted the servos white and fitted the pushrods.
Hopefully the components will arrive on the weekend, we will see. ;)
So thank you MRC EU for the prompt and kindly support. :Cool::Cool::Cool:
Andreas

Oh did not notice that one on thingiverse, thanks Pat!!

I'm reading about a few of you having issues with the blue box (MCB-E). In general, the problem occurs after connecting everything to the control box and putting the gear down and immediately noticing you can't steer the plane. The problem is 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.

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.
Test steering and rudder. Everything should work.
Cycle gear up and down 2 – 3 times.
Put gear up one last time.
Reconnect steering servo to the steering servo port on MCB-E.
Test steering with gear up – rudder servo should work, steering servo should not move with the gear up.
Put gear down, steering servo should work.

Once they are in sync, they stay in sync. The MCB-E is designed to stop your nose gear steering when the gear is up. You don't want your nose gear banging from side to side in the plane when the gear is up every time you use the rudder.

No, it isn't :Angry:

Sorry about that. We thought they were in the box with the plane. As soon as we received the L-39, we shipped them out immediately. We were putting all the spare parts away and found a box of gunpods a few days later. We opened up the remaining L-39 boxes and found there were not any gunpods in with the plane. Freewing boxed them separately and unfortunately we did not know this. Anyone who ordered from Europe who is missing the gunpod, please open a ticket and we'll send you a gunpod. I apologize for the mishap.

**Ron1950** · Nov 30, 2018, 10:00 AM

hey Tom what about gun pods for the us?

btw is anyone making those nose gear supports to sell? id gladly buy one and plus shipping as i fly off grass thanks

**Tom** · Nov 30, 2018, 10:12 AM

Anyone in the USA who notified us about a missing gunpod will have the gunpod shipped today.

**Ron1950** · Nov 30, 2018, 10:20 AM

wow thanks Tom

just got my shipping notice

**crxmanpat** · Nov 30, 2018, 10:36 AM

Yep, just got my shipping notice for the gunpod. Thanks MRC!

**Felixs10** · Nov 30, 2018, 11:16 AM

Just got what I assume is my shipping notice for the gun pod .. Its either that or my F22 from the 2nd pre order ( LOL) . a win win either way LOL.

Hey Tom ,

I experienced the same thing out of the box ( before you posted this originally ) I was part of the initial pre-order. I was able to figure this out within several minutes and all has been fine since. Have you guys found any bad boards to date ?

This is what my notice says:

We have tested every board we replaced and so far we have yet to find a bad one. The plane comes out of the box with the landing gear in the up position. I think the board is thrown out of sync when the plane is powered up for the very first time while the radio has the gear switch in the down position but the plane has the gear in the up position. Once it is brought back in sync via the above process, it appears to stay in sync. This is a new board for all of us. In the past, every new plane would receive a new control board. At this point, every new plane will either use this same MCB-E or the MCB-D so all of us will not have to lead a new control board for every new plane. We'll likely go back and swap these boards into existing planes and phase out the one off control boards.
