Thank you.
Have received all that hardware, finally.
Here is video of the suspension system.

I tried to emulate real suspension system as much as possible.
There are some compromises as everytime, but i am satisfied with this.

Springs are adjustable, range is 3mm.
They can be possibly changed for some thinner type.
Need to be tested in real terrain.

Arms are printed with ASA, 80% infill.They can take some serious punishment.
I think i can find some way to show you, how durable they are.

Anyway, both - Assembly and Printing guide are almost finished (80%).

I’m amazed. 3D printed kits are getting better when designed and sold by people like you who cares a lot about quality. It brings people back. I still have to build that Hetzer kit I have, planned for this winter.

Looking real good, Tomáš! Really cool to see the adjustable suspension setup, and near-solid ASA will be strong as hell. Can't wait for the test drives!

Thank you.
You can move that black spring holder up and down in range of about 3mm.This is how they can be adjusted.
3D print material arrived right now.Going to print last rubber bands for the roadwheels and to drive somewhere :)

Thank you.
I have a lot of news.Good and bad news.

First of all - i have experienced huge tragedy.Extremely bad news.
My hard disk (one year old) was destroyed right when i was working with that.
I didn't know Seagate Rosewood was a time bomb.But it was.

ALL MY WARPRINTS CONTENT IS PROPABLY GONE.

I have saved Cromwell 3D model, but Hetzer in scale 1/16 and 1/6 might be lost forever (I have only STLs of them).
Including all source files for assembly guides, all contacts, everything... everything related to Warprints is on that HDD.
I was stupid as f*ck because i dont have backups of this.I didn't believe the cloud.Now i will use cloud storages, i will be very happy.

Have sent that HDD to professional recovery.Biggest laboratory around.I hope they can recover that files and i hope i can afford that.
I guess i have to sale few kits to get that data back.Recovery can be impossible, anyway.

I am still shocked and stunned by this.It happened on friday.

At least, Cromwell is safe.Maybe if Cromwell files were lost, I would stop making tanks.
I dont know.It was huge damage anyway.
I feel like after the fire accident in the workshop.

Anyway - two lessons learned.

1. i need to make multiple backups of all Warprints related files.
2. i need to produce more kits and become larger producer, then i can afford expensive things like HDD recovery in the Lab.

Have some better news too.

Cromwell prototype is good runer.Driving that thing for 3 days now and its really enjoyable.
Dont have any fully printed wheel axles on my design, so i am driving that vehicle without any fear.
Climbing, jumping, trying to take that vehicle to some really hard situations.
It can lost tracks, when turning fast on the carpenter (dense, high carpenter ) and can become entangled in tall grass.
Vehicle can run without any problems, when turning in scale speed and avoiding really tall and dense grass.
Suspensions are soft enough.Vehicle is not jumping and shaking when moving fast on the terrain.

Putting UV protecting varnish on the upper hull and turret today.
I hope i can make a lot of pictures and videos tomorrow.
Vehicle is completely complete.
I dont have any IBU2 now, unfortunately (need to spent a lot of money for that HDD recovery).
Have to find some alternative way to show all functions of the vehicle with only basic RX-18.

This prototype vehicle will be for the sale within few days.

I have to take few days of the mental recovery and i am going to finish last few pages of the assembly guide.

Next good thing - i have repaired my two delta printers.They was offline for the very long time.Have one additional printer, so i have 3 more printers now.
Not a small number for me.This helps me to speed things up.
Have outsourced most of the 1/6 Hetzer tasks to free capacities of the biggest 3D printing farm in the country.
Have a lot of sidejobs there, using printers for 1/6 Hetzer parts when they are in idle.
1/6 Hetzer might take 1500-2000 printing hours, so i need some really serious capacities to make at least one kit monthly.
It seems to be solved now.First kit is being finished in some 10 days.

And last thing - i have started Ebay store.There will be some accessories, related to Hetzer and Cromwell in scale 1/6 and 1/16.
Occasionally, there can be even full kits available.Anyway, kits are mostly reserved before they are printed.
Its new store on the ebay, so i am very limited there.I can have only two active listings.Its like a bad joke.
I have to advertise shop with two things for sale.Bad joke.
Anyway.Shop is here.Smallest RC tank store on the world.You can spent hours looking on that wide range of stuff :crazy: .
I have checked that right not.Shop seems to be empty, but here are these listings.
Dont know why they are invisible in my shop and it seems to be empty.I will check it out later.

https://www.ebay.com/itm/164948714615


Still walking forward, despite of hard knockdowns.I hope all will be better soon.Working on that.
Long text today , Thank you very much for reading.

I’m really sorry to hear about your hard drive, I hope the recovery is successful.
Think I have copies of the Hetzer 1/6 & 1/16 assembly guides if you need them.
Good luck with the shop
