Are the screws that hold the clear cover over the mechanism tight? it is possible that the clear cover is lifting up a bit and allowing the gears to slip.You can also try adding a second washer to the ones you added.I lost those metal pieces too and just used a brass rod cut to size to replace them.

Hello!

I'm from MX City, the other side of the world jaja.

Well, I had the issue of the legs about 4 years more or less. When I get the final volume and test all together (with the fuselage over) indeed the problem was annoying and frustrating.

After 1 month looking the answer I quit, but, yesterday since I completed my TB1 deagostini I decided to give a second try then I read all about this issue. Indeed, the problem is related to the gears and the mechanism of it yet I can not assure is more related to the fuselage, on my experience is the mechanism then I'll explain:

1) The gears were jumping once you turn on the TB, the problem is on each gear that is close to the motor, the black section with the clear part (uhmm lets say the train for the legs) is not good enough or tight to press the gears so they don't "dance" while is moving, that is the cause of the sound like tack tack tack tack and the legs getting lift disorganized.

2) The power of the battery is another factor, if you have a weak battery the mechanism simply will not have enough "juice" to lift the full model (Is a small motor, we can't ask a lot for it but serves us well when all is correctly set).

3) Finally, indeed, is necessary to check all the parts are correctly set, I figured out that I didn't set the small metals that are into the train when you already placed the telescopic leg, they are 4 small metal parts that allow the train move slightly and softly into the clear part if you do not set it the full mechanism will start jumping again.

Now, tu tururuuu turuntuntuuun tun tun tuu tatararaa tarantaaan!!

Solution:

I try my best to attach pictures of my home fix, actually, y used unnecessary part of the TB1 legs to make this works, as someone mentioned before you need to use a washer on the gears that are close to the motor must precisely close to the intakes, and a third one on the right side of the thruster, on the opposite side of the ON/OFF switch, should be a thin washer and will help to press the gears between each other to compensate the lack of pressure in the model. This might vary between each model of yours, mine got the three gears loose then I needed to add three whases, add it on the inferior gear, not the upper since the problem is the bottom gear does not fit correctly for that tiny space that left to make the contact with the other gears.

Finally, I didn't buy a metal washer as I mentioned I use a small, thin piece of plastic that I drilled through with a hand drill (Not an electric one) then I make the hole wide enough to fit with the metal part and used "Kola" to stick it to the gear.

After doing this on the three gears the sound and the jumping of the TB2 stoped totally even with the fuselage, I read that some people fixed by not screwing the nose section (it worked for me also but not for long since the problem is with that "jumping gears".

Suggestion, try each of the gears in your own model and see if they are "dancing" up and down, use a pen or pencil, and if you see there are millimeters missing to make the contact correctly use this process on each one, if you don't I can tell you that the problem will go on until the teeth of the gear get broken for that takatakaka issue because they are smashing and getting out of the correct way of movement.


Thanks for reading, was a full adventure this kit and I hope Degostini take care of the details like this, after all, is a lot of money and is not a simple mechanism as if is not correctly calibrated can easily get broken.

I got mine from HLJ.com not directly from Deagostini so my instructions were all in JP jajaja was headache and I'm terribly sorry that I can not read all the magazines :( I don't a sh....of JP
(T-T)

Have a good one!

I also encountered the same problem. Nothing wrong when running without the top. But when the top is screwed on and the full body is completed i get the same problem as described here. I relieved that I am not the only one but also quite dissapointed that after a very expensive build the legs do not work properly.

I already disassembled and re-assembled the motor, legs, etc more then a dozen times still leaving me with the same result. Hopefully the washers will help

Hi Dirk-Jan

Firstly, welcome to the forum.

The issue with the TB2 legs has been sporadic, but I`m not denying its happened.

As yet I have not heard of anyone where the the thin washers have not cured the situation.

Personally, I never had an issue with my build.

Try the washers and see how it goes.

Good Luck.

Hi Delboy and other Forum members,

After reading all your solutions to the problem i bought myself online 5x (Ring M2,5 plastic 6,0x0,5mm) washers and put them under the gears. Problem solved. It's working.

Thank you very much on all your help in solving the problem. It's much appreciated.

Kind regards.
