Thank You Niels

maybe Your tanks never suffered, Wibblywobbly :D
even that first T-14 (PLA) was ok in the car for the short time.
but on the direct sun was melted very fast.

i can absolutely understand if you dont trust me, because i was in the same position 1-2 years ago.
3Dlabprint 3D printed RC airplanes is printed with PLA, so what.

what? :D

melted on the direct sun, standing on the table on the first show :D
it took 20-30 minutes.
here in Slovakia, we dont have tropical weather at all.
I did not buy PLA from that time.but ASA is pretty badass sort of material (its melting down in the range of 90-110°C).i love that and i have completely replaced PLA with that.

PLA sprockets was rock-solid.i have destroyed some gearboxes, tracks... but sprockeds are still in great condition.
i dont have tested that new ASA sprockets in terrain yet, but i hope i can start some test drives in two weeks.
sprockets was printed with 70% infill i think.maybe 80%.i dont use higher values for infill.
PLA is harder material, even on the rockwell scale.have better tensile strength value.its more suitable for sprockets.
so i have to test this new ASA sprockets and if i broke even one teeth, i have to print sprockets with PMMA (plexiglass).
its hardest FDM material for this time i think (but i am not sure).its even hard to cut this 1,75mm fillament.very specific material.
printing of the little parts like this from PMMA is not difficult.

about the roadwheels - yes.PLA roadwheels are usable and durable (before melting).
i have two bearings in the Armata roadwheel.
new roadwheels consists from the ASA wheels and TPE88 (soft rubber) rings have to be tested, but i dont see any reason to failure.
3D printed roadwheels can be better like the stock heng-long roadwheels.
-there is no backlash in my axles and wheels
-every axle in the vehicle can be easily centered, including turret-turning motor sprocket.
- 3-bearings anti-backlash turret ring
-each of the important axles have bearing (there are lots of bearings in the armata)
-every screw in the T-14 have nut (inserted after the printing)
-builded-in tracks tensioner
3D printed RC tank can be mechanically better like stock chinese RC tanks.why not...

wait for my next project :shh:
WW2 related.real scale 3D model of the new vehicle is almost ready.

hi.
Armata is almost ready for the battle.i have done first, short test.
i dont have installed mudguards and some details yet, for easier work.
its performing well.just need some fine-tuning of the Elmod and new, stronger gearboxes.

controlled with Flysky th9x and OpenTX firmware

yes.its handy.
this big service hatch on the turret is great, because i have an easy access to the videocamera.its used to charge battery on the camera too.
but yes.its great for the inspection of canon.
optionaly, with the airsoft canon, service hatch is used to feed the canon with the balls.

Hi,
after a long time with T-14.
I have some photos from the last days of the session.Riding in the home of my T-14 - our tankodrome in the Slovak National Uprising Museum (yes.hard mounted in the open-air tank museum :thumbup: ).
I love to drive my Armata there.

I have prepared a huge Assembly/Printing guide with BOM and lots of other things needed for distribution of STL files.Next turn is on the famous UVZ.
I have started royalty fees negotations to allow me to sell STL files.
Hope i can afford price and conditions of this.

So i am hoping and waiting :|

I am wondering too.
Everything is ready, but UVZ dont give f*ck about.
I have asked for the permission and started negotations ONE YEAR ago.
I dont know.Its maybe because there are problems in UVZ, maybe just took too much time.
After all, i have a lot of work with releasing Hetzer.Then i can ask again.
If Hetzer make some real money, i swear, i take a flight to Yekaterinburg to finish this and receive licence for T-14.

A very interesting thread :thumbup: It's such a shame that the opening pics had disappeared :thumbdown: The downside to posting from 3rd party sources- as we've see all too often with Photobucket blanking archived threads out- is that your pics can vanish into the ether. :(
You've displayed brilliant design and production skills here, 50koruny,. In fact, your T-14 is a Tour de force :clap:
More than that, the discussion that emerges here on plastics is likely to be useful to anyone contemplating printing 3D models.
The thread also raises the issue of the durability of of certain plastics. I guess, it's always a risk demonstrating models outdoors on a hot day- or even working in an environment lit by intense sunlight; or even travelling with them in a hot car.
It must be very distressing, to see a model that has taken many man-hours to assemble, warped and distorted on the workbench. :'(
One lesson I learned years ago, was how to keep my precious vinyl LPs out of direct Sun. My ex-wife, left my (then) brand new copy of Frank Zappa's 'Hot Rats' on the table, by the window., on a very bright day.
When I came home, the LP looked like Roy Orbison's hairdo :thumbdown: :lolno: It played like a merry-go-round.
Good luck with getting the rights to produce the T-14!
