RC Tank Warfare community hobby forum

Hi,

some time ago I start to build an M7 105 Howitzer Motor Carriage " Priest"

The tank is based on a Heng Long lower hull and part of HL upper hull :





Many details are made from pictures of Squadron Signal Walk Around book :





The gun is from Shapeways production :



Many parts of the gun mounting are made of brass machined and welded by myself :











The side and front armour is made of plastic card of 1.5mm thickness:





The pulpit is made of rolled plasic card of 1mm.



The gun armour is made of welded brass sheet of .3mm





The gun legs are made of H brass profiles cutted and silver welded.

Telescope mount M21 is made of bress tubes machined and welded:



The left motor was too high, so I made a modification of the gearboxes allowing to place the left motor lower
and allowing to have the true position of the gun :







The gun equilbrator :



The complete gun with all sighting devices ( m21 telescope mount and the M4 range quadrant )

Love the guns detail . Is it to be static when done or will you make it able to move by radio (elevation , recoil, traverse)?

Hi,

it is not easzy with Heng Long radio but i will try.

Boris

I would think the traverse and elevation could be done with small rc servos run off the HL receiver. The long recoil would take a lot more thought but should be able to be done with a servo also.
Sure would make the project come alive to be able to have a radio controlled main gun. especially with all the fine detailing you have done with it.
Even if you don't I still think your build will look fantastic.

Hi greengiant,

I''m not a specialist in radio control, so, i have done one experience with elevation of the gun of my M10 Tank Destroyer with a microservo. But the motion is to fast even with the shorter arm of the microservo.

Ho to do ?

Boris

Hello,

I resumed the post after a month in the hospital for a pleural effusion for which I was drawn 2 liters fleet and found after many exams a cancer sarcoma and for which I am in full chemo, so I'm not very brave !

I think again the machine gun from the mounting system on the circle, I ordered the elements allowing me to do it in brass.





Meet you later !

Boris

Still looks great
On the servo, the shorter the arm is the quicker the movement appears the longer the arm is the slower it appears if hooked up to a non proportional control source. HL radios only have proportional control on the engine drive speed stick.

Hi,

I would like to make a true machine gun monting on the pulpit !

I bought, expensive, the gun holder assembly of at Shapeways but it will not, it's too lace!

I think again the machine gun from the mounting system on the circle, I ordered the elements allowing me to do brass mounting

I manipulate this material better, two profiles, a H for mounting a machine gun and U soldering on the H, and mounting this assembly on the "pulpit" of the priest!

Boris

Spectacular work, Boris. I'm really impressed by the metalwork you've done on the howitzer.

I've always had a soft spot for the Priest, it was one of the first kits I built when I was a kid. Not quite the same connection that you have with it, though!

Hi,

waiting for the H and U profiles to make the .50 machine gun mountng, by the time, I make the electrical mounting with the
2.4 Gh receiver, all functions are ok !!
