HengLong T-90 detail up

This board is for talk about tanks after WW2. The ups and downs. The ins and outs. All of it here.

Hello everyone.
I detailed up my HengLong T-90 tank.
I installed BEIER-Electronic 's sound board USM - HL 2, downloaded the actual T 90 tank sound from YouTube, and edited it using Audacity. The remodeling is as follows.

• Convert BB spec to barrel recoil and gun flash specification
• Gun flash of anti-aircraft machine gun on cupola using chip LED.
• 360 ° turret rotation using slip ring
• Added periscope
• IR Shtora, marker light, side marker light, added rear headlight on wind sensor pole, searchlight on turret, and brake light were remodelded to light up.
• Added rectifying fin board to engine exaust port
• Change the stock headlight guard to brass wire
• Detail up the back of commander cupora hatch
• Speaker exchange
•Removal of molded front fender fixing rod and making it by brass wire

Lighting

•Since the vertical space inside the tank is narrow, remove the battery box.
•Change upper and lower hulls to removable magnet type
I sprayed the surface primer of oxide red on a metal track, and sprayed AFV TRACK COLOR (No. 06) of MODEL KASTEN COLOR with an air brush. For expressing dust, I painted conte pastel shaving powder dissolved in PETROLE.
After attaching this track to the tank and running it several times, the painting of the contact surface of the track with the ground and wheels will peel off and become more realistic.

Nice! I really like the little marker-lights. Shouldn’t be too hard to replicate for me, since the red and green LED can be soldered parallel to a cable. They are 3mm?

One specific question : what do You mean by “tip LED” ? Did You use some kind of SMD-LED for the AA gun? Or did You maybe replace the barrel with hollow rod and a small glass fiber with a 3mm LED hidden in the body of the gun? (A trick I used on my Challenger II to great effect)

I’m busy working on one of my T-90’s, and really want that big AA gun to flash too when triggering the machine gun.

Thank you for your comments and questions.
What I used for Cupora gun and brake light is 1608 LED Chip of 1.6 mm × 0.8 mm × 0.6 mmt, not 3 mm LED. I soldered 0.3 mm enamel wire to this. The following is a picture of the lit Chip LED, 3 mm LED and brake light.
I'm sorry. Tip LED is wrong with Chip LED.

Thank You for the information.

I’m afraid, though, that chip leds are a no-go for me. Bad eyesight and shaky hands aren’t the best when trying to solder enamel wire to 1mm objects. I think I’ll go with the parallel 3mm led for the lighting, and go for the glassfiber solution for the gun. The body is big enough for a 3mm led.

Thanks anyways.

Is that so. Since it seemed to be difficult for me to make lighting and external AA gun flash using glassfiber, I used this chip LED.
Indeed the Chip LED is very small and initially I thought that soldering would be difficult for me. However, since the Chip LED is very inexpensive (since it is about 2 dollars for 20 pieces, the shipping fee is higher), so even if you fail this work would be less damaging. I placed the Chip LED on a flat plate with a double-sided adhesive tape and also positioned the end of the enamel wire (plated with solder beforehand) with a double-sided adhesive tape, and soldered it carefully so as not to too heat much..

I will attach a YouTube of this HengLong T - 90. Since the turret rotation motor is a stock one, the rotation speed is slow as a modern tank. I will replace this motor with a faster motor in the future.

Son of a gun-ner wrote:Wow, that TIP LED looks like what they use in COB lamps, didn't realise you could get them individually. I have COB lamps in my kitchen and bathroom ceilings, they're very bright.

They are pretty new LED technology.

Edit: Well, new for the open market and consumers.



Certainly it will be easier to work if a very small COB lamp or tape Chip LED can be used. However, even COB and tape LEDs are too large to incorporate the lighting function into the tail lamp parts of this T90 tank. Anyway, Chip LED and enamel wire are very cheap, although soldering work is necessary. I also failed several times, but soldering the Chip LED is not so difficult after grabbing the trick. Although it costs a little, soldered Chip LED of ED wiring is also sold as a product.

As for WW II tank, I understand almost what kind of equipments or OVM are attached, but I do not know enough about modern tanks. For example, in the Heng Long T90 tank, I did not understand at first what the single rod protruding like a horn on both sides of the root of the gun barrel. When I investigate the picture of the actual T90, I noticed that this is not a single rod but a V shaped arm that lifts the gun barrel.
Looking at another place of the HL T90 tank, the handle is simply molded on the upper side of the left and right rear fender, but I can see handles of exactly different shapes at the same place of real T90 tanks and 1/35 MengModel tank. Considering from the real tank picture, this may be a metal fitting and handle that fixes the drop-in type container to prevent the container from jumping up by the impact when the tank is running. When pulling up the container, the bolt of this metal fitting would be removed to use this handle.
Since the right side container would be a fuel tank, it seems that a protective boad is attached to the rear part of fuel tank to prevent damage from the wire rope hanging work etc.
Here, I have upgraded these parts.

If my reasoning is incorrect, please let me know.

I placed the parts on the photograph of the real T90 tank. I will also post pictures of original molded handles before detailing.

I added several things that were missing in HengLong T90 tank. The gun camera in the anti-aircraft machine gun and the operation arm joint, deformed periscope, and the underside of the gun barrel lifting arm which is omitted.
I erased the parting line at the top of the AA machine gun and added a little detail and rounded off the corners of the discharge cartridge bag.

Nice work. :thumbup: The HL T-90 is an early Type, and most have now been sold for export. :wave:

Thank you for your comment.
As you say, the HL T-90 tank model is an early type and has a cast turret. I heard that HL copied 1/35 scale Trumpeter model. MengModel's T-90 tank is a recently welded turret type (Uladimir), slightly different in shape from the early type.

Furthermore, I got a little detail up the parts omitted in Heng Long T 90. First I opened a rectangular hole around the exhaust port. I added remodeling around the exhaust port, exhaust port top cover, tiny grab handles and upper rib fixing bolts on the side skirts, and bar and conduit pipe on the upper hull.
The detail up of this T90 tank now is done when I come up with it and want to do it. I think that there is no need to stick to that much, but on the other hand I cannot help detailing up when I know that detail. For modern tanks with complex shapes, there are quite a lot of materials to make up for detailing. I think that HengLong 1/16 scale seems to be in the category of toys, unless it has at least 1/35 scale MM model level or higher detail.

I will detail the complicated shaped exhaust ports a little more. I cut a thin copper sheet and bent to make the top cover of the exhaust port. The mounting bolt on the cover is made by attaching plastic hexagon bolt of MengModel to a copper sheet. Next is the cover that I made on the real exhaust port picture. Just put this on the original exhaust port.

Since the laser rangefinder cover on the turret is also different shape and thickness from the real one, I removed the original cover and made it with a thin copper plate.

I felt something wrong with the molded rod behind the engine Inlet shutter of Heng Long T 90 tank. I cut off this molded rod and rebuilt this rod with brass material and plastic material, referring to the real tank photograph.
Furthermore, since some bolts are omitted in the vicinity of the rod, I added them.

What I got in this time is this double speed turret rotation gear unit. The casing and gear are made of metal. As for a modern tank currently in use, the turret rotation speed of HengLong' is too slow, it seems just right at about twice the speed. There would be a method to replace the motor in the unit to a high performance motor for mini 4WD, but if I do not insert the proper resistance there is a possibility that the motor and controller will burn. In this time, as a safe way, I used the DKLM RC 2 × Fast.
