3dP Type 95 Ha Go

[SoCalBobS]

I have a question about an online seller of 3dP tanks, in China of course. Has anyone tried him out? He's on eBay and elsewhere. I have an inquiry into him, but an independent experience would be great to hear about. He prints a number of tanks, don't know if it's his, licensed, or not. He says that most tanks are HL 7.1 compatible, but that's all the site says. His videos show full function, driving barrel recoil, lights, the works. What does he provide and what needs to be obtained elsewhere. I know there's no electronics, but do they have motors, gearboxes, any hardware?

I'm fascinated by obscure tanks, those that will never be mass produced. This is one, the Japanese Type 95 Ha Go.

I think William, who you met a couple weeks ago, ordered one. I don't know if it has arrived yet. You can ask him about it. It is the same store that you stated. he mentioned that it would take 40+ days to arrive. He probably got 20 days left.

I have two from said seller. They have changed their name online a few times. Consists of a guy in Canada (or he used to be), but the printing is done in China by his associates. I bought it believing they were authorized copies or their own original design, but that is far from the truth. A lot of them are unauthorized production of other peoples STLs like warprints and the ukranian guy, but they will assure you that isn't the case. The pictures and videos are of the best case scenario/already done but what you receive is gonna be very rough and low quality. I have a Churchill and a Hetzer. I forgot what type of material they use, but they warp in warm weather so I can't say it's PETG or anything like that. Print lines all over the place. Fitment was okay for the most part, and ass in other cases and required some significant smoothing and sanding. They run very rough. Print consistency and shape uniformity was rough so they drive like cars with bad alignment and very crunchy. He advertises these kits with hardware sometimes, but the hardware included doesn't match or make sense at all. The Churchill with its intricate front sprocket was lacking hardware to make it work like pictured so I had to come up with my own hardware and creativity to make it mount and adjust. I probably spent a good $30 on hardware and trial and error. The roadwheels on the Churchill were paper thin and broke under the weight of the tank assembled, as did the suspension arms. Probably the flimsiest 3d print material ever. I had my friend take one set and make beefy reinforced ones and that made it durable enough to use. I don't take this 3d one anywhere but it is all assembled and able to run, but by then, the Tongde came out and I got a battle ready Churchill out of that.

Also note that he cannot provide instructions because he's not the original maker, so he'll point you to wherever the designer may post their notes, otherwise you have to be good at guessing. The items did arrive and with good communication. When I was missing something he did have his Chinese counterparts print them up and send to me at no charge, but that took a minute. So you will want to get cracking on the project right away or risk missing your window to get any problems sorted out.

So in summary, to his credit, the sales part is fine. He was reliable and communicative. But the actual product is terrible. Don't buy unless you are willing to make it work and use inferior materials. When I am unburdened by a backlog I may attempt to build that exact model via the 3d files available for purchase just for fun. I can print in way better quality in PETG at home now.

Wow, good info! Thanks guys. I did buy a "Kugelblitz" turret from the Canada/China connection, and it did come with a good set of parts. It was one of those "shot in the dark" gambles that paid off. He was quite eager to make the sale, and dropped the cost substantially. A turret is different than a full tank so yeah, I wanted feedback. As noted, the seller was communicative, and the product did take weeks to arrive, but it did.

I wouldn't expect the Ha-Go to be a rugged battler. It would be a fun project though. Given its size, I imagine HL motor/gearboxes would be too large. There is a motor gearbox that others have used for small tanks; N20 is the name I believe. Tang, maybe we can double up and take advantage of each other's expertise!

Here's his turret on a HL Pz IV:

Andy's Hobby Headquarters had a 1/16 scale kit about a year ago for sale for about $100. It was a static kit but looked like it could be converted to RC relatively easily. I almost bought it. Now I cannot find it anywhere on the internet. Call Andy's to see if they remember or check their old youtube thread for a build blog. Thanks Tang for sharing you experience with the E-bay guy. I have drooled over some of the things that guy printed up, but always hesitated as it looked flimsy. I want a battle tank not a maintenance nightmare'. Even the static conversion would be delicate. Thank goodness for Tongde to come out am make the more rare tanks.

Here's the motor/gearbox I was thinking of. This one is rated for 12V, but says 3-12V, so 2 cell li-ions should work. $19 for 2 on Amazon. I wish I'd know about these when I made my FT-17. I used the Heng Long 1/24 tank innards, and it made this run at light speed!

Bob I want to very much do an FT17 as well, may pick your brain about it later! lol

I have an FT17 kit that I will be converting eventually with the Tamiya dual motor gearbox. Others have used it, but those N20 motors would be smaller. The Tamiya uses dual 130 motors. https://www.tamiyausa.com/shop/educa...ble-gearbox-2/ You might want to find an FT17 kit now if you want one as they are discontinued. Someone did contact Takom and they said they are not releasing a new version of the kit anytime soon. There are several different models to choose from, but all of them have become pretty scarce and in most cases expensive. I waited a bit and found one for a decent price on Ebay.

Back to the topic. Inkor is the Ukrainian guy. He is aware and has talked to the guy in Canada and does get kickbacks...sometimes. I'm sure he's not delivering on every sale and Inkor is aware of it also. From what I know of him, most of the tanks are printed in PLA which will deform in the sun and it will degrade over time as it is made from corn to be biodegradable. PETG or ABS has much better heat resistance. Some have said the quality is OK, some say it's crap so it is a crap shoot. It is most definitely true that the guy does not have permission to sell all of what he sells. Warprints has specifically told him his not authorized to sell his stuff. Inkor sells all of his designs on Cults3D where he does get most of the money. Cults3D does take a cut as they are hosting the sale.

If you click on any of the tanks, there is "Live View" link for the tank. That view contains a deconstructable 3D model of the tank so you can see the inside of the tank. It will show you the motor setup. I can't view it from my work computer. https://rc3dtanks.site/detail.html#ha_go He also has a Discord server where you can ask questions and report bugs under the channel name "RC 3D Tanks".

The Ha-Go in particular does not use a standard Heng Long gearbox setup as it won't fit in such a small tank. It does use the gears from a Tamiya gearbox which from Inkor's link is the same one I mentioned about using in the FT17. https://www.tamiya.com/english/products/70168/index.html Having my own printer I've never ordered from him so I don't know how much he includes with his kit. The normal Heng Long 7.1 should fit as it does use servos for recoil and elevation.

Info from Cults3D page:

Based on Heng Long TK-7.1. Does not support BB unit.
supported:
- uses gears from Tamiya gearbox
- canon lifting
- smoke
- fully functional suspension
- recoil and elevation with SG90 servos

IMPORTANT!!!

Tamiya set is the one that I found possible to use. The gearboxes itself are not being used, instead there's a custom made gearbox housing that you have to print and assemble. It also requires printing gear so use nylon or something tolerant to temperature and tension.

FYI:

I emailed the seller and got some answers, for this tank specifically.

- The tracks are individual links held together by steel wires.
- The Heng Long motor and gearbox aren't used.
- The turret is rotated by a servo. No further details.

Not planning on moving on this right now, just gathering information.

How about a Type 94? This is what I was planning to do a year ago.

Now thats tiny!

Hello everyone my name is Peter I am new to the rc tanks work.

I bought 3 heng long tanks with no problem and I bought a Torro Panzer l V that keeps throwing a track.
how do I install the track properly and adjust.

Thank you in advance for your help

[quitcherbitchen]

HI Peter John,
I had a Torro Panzer IV and it never threw a track. I don't think it has a track adjustment. How much slop is in your tracks? It might need a link removed to tighten it up. Any pictures while holding the tank up to show the gap between the wheel and the track. Honestly the Torro tanks are hard to have track problems, but I believe you when said yours did. Probably simple as too many links. The gap should be about a centimeter if I remember.
