Ok.I have to redraw the roadwheel and arm and reprint 40 parts right now.This have to be third serie of the roadwheels.
There was only one bearing in the roadwheel (not in the arm but directly in the roadwheel), but i dont have counted with the play of the chinese bearings.
Roadwheels with play can destroy this 3D printed tracks in seconds, soi need to place additional bearings in the swing arms.
This Hetzer need to be a good runner.Potentionally, i can make a problem for a lot of people if i neglect something or i make a mistake.
Nobody wants problematic crap, even when is looking good.
Now i go to draw

Thank You and dont worry.This is not a problem of my bad luck with bearings.This is just a global situation about bearings.Chinese bearings have big axial play, because of the low accuracy of the balls.
Nobody want to spend 100€ for 24 bearings of highest quality.If some design of the hobby RC vehicle need bearings for 100€, this is definitely wrong design.Thats all.

I need to do this with 3D printer, cheap chinese bearings and screws.This is only way to make my tanks accessible to anybody with 3D printer.Not just for a few people with lathe.

I have figured out this.Second bearing to eliminate play of the cheap bearings.Good experience from the T-14.
But i need another 5 bearings .Very common type of the bearing.I think i can found some even in our local store.

Hi.I was badly sick.Some kind of the flu.

I am back and i need something to do .Today i have figured out how to do some progress on the Hetzer even without this additional bearings (arrived in few days).
Today i have prepared some simple temporary 3D printed "bearings" just to put things together.
Hetzer was runing first time today.I am pretty happy with that.
Propulsion system is smooth and quiet.
I can make better photos tomorrow.Even a video, maybe.

Need to order some small LiPO battery right now.I want to equip gun tomorrow and drive that thing again.
Its very funny to drive, because is very practical and little (oppossite to T-14).

Thank you, both.
I have figured out how to put sound and smoke inside.Its enough space inside, but i dont have confirmed this overlay with gun installed.
My bad.I am not able to install gun because i need this bearings from the last delivery.
Seems to be almost impossible to fit TARR smoke generetor (i love TARR) so i keep going with (almost ) stock Heng-Long smoke.

Its really fun to drive this.This Hetzer seems to be great runer.Just need to tune up this Elmod a little bit.
