Greetings, colleagues.
For many years I was a reader of the forum. in my opinion-the most interesting on AFV subjects.
And now I want to create my own topic. Please forgive the grammar-it's an automatic translation.
Currently my project is LVTP-7/AAVP-7 family. the basis - model LVTP-7 from the Academy and AAVP-7 from Nobby-Boss:
LVTP-7 early,
LVTR-7 (pre-production),
AAVP-7а1,
AAVP-7а1 RAM/RS w/EAAK,
AAVR-7а1,
ААV7-С1 RAM/RS w/EAAK.
The latest - model AFV-club (conversion Hobby-boss).
In addition to the basic sets used photo etching Eduard, Voyager, Hobby-fan conversion for LVTR-7 and a box with spare parts:).
What do we have at the moment?


AAVP-7а1, AAVP-7а1 RAM/RS W/EAAK, AAVR-7а1, the interior will be modified sets of photo-etched parts by Eduard and until set aside.
Currently working with ААV7-С1



Currently working with ААV7_С1.The main differences between linear AAVP-7а1 RAM/RS and ААV7_С1


A part that is not in the set, but is on the prototype.


I think I did it:). To be continued...

Thanks, Ryan.
Continue. The quality of resin casting from Hobby-fan is very mediocre. many defects and shortages.

fixed mount over the hatch and fan cover. with increasing carelessness is visible - fixed


General view at the moment:

And parts used for construction

The next stage is the antenna. The prototype has them..... a lot!

The photo shows two IDENTICAL sets from Voyager. Pay attention to the size of the flexible part of the antennas. WHAT?

Thank you, colleagues. I am pleased with your attention and support!
We continue construction. Yesterday was the day of the antennas. A forest of antennas is a very good definition. There are 10 of them on the prototype, if my eyes don't let me down. Voyager's kits were used in the process. in my opinion, they are not bad, although somewhat over-sized.



As a base antenna mounted on the armor on the sides I used items from a set (or rather two sets). They seemed to me better than the bases of the conversion set - with the wrong angles and curved surfaces.

The most difficult thing was with the main antenna (I do not know how to call it) - parts from the set were lost and the quality they did not suit me. In the end, were used two base antennas from Voyager ( Merkava ), brass tube, plastic and a lot of patience. Yes, some of the children from the set also came in handy. The result on the photo.


Next is to install some small things.

... and there will be one question-what are these strange details, how they look on the prototype and how many of them should be?...

In the photo of the prototype-round details almost in the center of the picture.


Do you need a more detailed analysis of the shortcomings of the model and the details that need to be corrected? I will be grateful for your help and comments, especially critical.
Also, I will be very grateful for the photos of interesting prototypes - there are very few photos of the control machine in the network.

Yes, I forgot to tell you-the main antenna is mobile. And can be fixed in any position. I don't know why I did it.
but so more beautiful

I built the Academy LVTP7 and definitely place it at the bottom of the list. One detail to tend to on that kit is the cargo hatch latch locks. Each cargo hatch has two hatch locks, which is correct for the LVT7A1/AAV7A1. However, for an LVTP7 there should only be one cargo hatch lock on each cargo hatch aligning with the cargo hatch post which the rest on when fully open.


I have to do some digging but I have the Technical Manual for the C7A1 RAM/RS. While it is not a great reference for image detail it does offer type and location of antennas.

Thank you for feedback!
Daniel, thanks for the clarification. For any information on the prototype, I will be very grateful!
I didn't pay attention to it at once. But when working with LVTP-7 I'll do that.
They're next in line.

This is to maintain interest in the topic:)))

Thanks for making me discover the AFV Club set for the command version, I didn't know it existed.
I hope the castings are better in the one I bought ....

Good day.
Robin, I'm glad I could help.
This is an interesting set. it's still on sale at Hobbyeasy.The quality is really 6 out of 10-amazing - conversion set for LTVR7 the same company cast very well.
With a strong desire, you can make it yourself, using the base model LTVR7. From a complex there is only the antenna.

I did a 1/72 conversion using the AAVP7A1, AAVR7A1 and plastic to create an AAVC7A1 that was in a platoon at Camp Fuji in 1993 – a pre-SINCGARS and pre-RAM/RS vehicle. ET Models’ photo-etch provided some finer details.






My 1/35 Academy LVTP7 in Thai markings. Had to correct the lower forward hull and cargo hatch locks. Will do a Hobby Boss LVTP7 instead of tackling the Academy kit again for my next LVTP7.

Dug through some of my pics and found some which I hope are helpful.
The items in the green circles are the cargo hatch locks. The purple squares are the cargo hatch support posts, onto which the hatches lock onto when fully opened. On the 7A1 variant there are two sets. On the LVT7 there is only a single cargo hatch lock and cargo hatch support post on each side. Also in that image, the aft cargo hatch handles are the older style which is appropriate for pre-EAAK or LVT/AAR7 vehicles.




Some images of the AAVC7A1 as well. The first several date to 2004-ish whereas the final three date from 2011-ish. You will notice some variation between antenna arrangement as well as a new type of antenna on the newer C7s. I also included an image of the EAAK antenna post. As you mentioned earlier, it is a very odd shape.

Good afternoon, gentlemen. I'm still building:).
Daniel. thank you very much for your comments and photos. Your models are impressive! You've been very helpful.
As I can see from the photo, my prototype refers to the machines of the 2004 period, judging by the antennas.
I added some wires to the top hatches of the landing and crew.

And i made the mechanism for opening the hatch over the engine. This detail is not properly completed Hobbyboss. missing from the Academy model and incorrectly made by Voyager.
Photo: so offers Hobbyboss.

It's supposed to be like that.

From left to right: item before revision. detail in the process engineering(from above kit that offers Voyager). final result (top Voyager down modified plastic Hobbyboss).

After mounting on the model:

Voyager offers an oversized mounting block. On the photo - in comparison with Hobbyboss and the Academy.

Cherry on the cake-a machine gun on the swivel. The bracket is similar to the original, but the machine gun is very much in doubt. What can I replace him with?

Final installation - all parts are laid dry, without glue. The model is ready for application of anti-slip coating, the addition of bolts and some fasteners, then the soil and painting. What do you think needs to be added or corrected?

Excellent catch!! All of the kit manufacturers and after market sets have missed these details. The "tube" is the intake plenum torsion spring. There is a small arm which connects the spring to the intake plenum. The larger square bar is used to secure the plenum in the fully open position. There should also be another bar for the rear plenum.
Unfortunately this area is not well photographed but I'm sure I have some stashed in my collection/library. I may be able to scan a page from the manual which may illustrate it better.

Thank. I had photos of this area, the second bar for fixing in the open position is attached approximately here.

I pulled from the Technical Manual what might be helpful. I also located couple more pics that focused on the area. The forward most “eye” on the intake plenum is not used – not in practice anyway. The bar is supposed to be mounted/secured to the forward plenum using those two “eyes” when not in use. I have never seen that done. The intake bar is typically secured to the “eye” on the plenum deck and left to rest atop the torsion spring when not in use.
The last photo was one of “my” Tracs and provides what they look like with the forward plenums raised during an at-halt operations check.

OOOhh yeah! Excellent!
Daniel, you are my hero! A great great great thank you!!! These photos are exactly what I need. I'll do it on all 6 APCS.
Are there significant differences between these mechanisms in the early and late (LVTP-7 and AAVP-7)? I can't find a photo of it LVTP-7 on top. Whether they had anti-skid on top and the hatches of the landing?
In addition, I found an interesting fact - cargo hatch support posts on early LVTP-7 had no inner wall and had a П-shaped appearance. In addition, the photo shows that the upper hatches of the landing suspended on 5 loops not 3 as done on the model.



Edward is offering this variant with its set of photo-etched parts.

thanks for the support, Olivier.
The main thing in this work-to bring it to the end:)....
For fun - photo comparison of AAVP-7a1 and Chinese ZBD-05. estimate the size difference.


The show continues....

I cannot be the only one who thinks the water in Ivan's photograph of the (real) water crossing looks great but the skin on the crew needs some work?
