Servo Elevation mod for Tamiya tanks
#1
Thread Starter

Well guys i would like to try to use a servo for my Pershing elevation . Servo's have 3 wires and all other elevation units have 2. Whitch wire is not needed. Any one have some picks. I know this is been done some time ago so i tried to do a search and didn't find anything. Any ideas?

When I worked on Nemisis's4u JagdTiger, I tried using the stock Tamiya elevation motor for the gun, but it did not have the power for that long hunk of metel, so I ended up using a stndard Futaba servo, I just plugged it into the receiver (after locating which port was for the said function). Did the same for his SturmTger. Hope this helps.

Maybe you have to modify the servo also to a "non return to zero" type. If you have the FO kit, you can simply connect a Y-lead on the reciver cable to the MFU-unit.

One other way is to turn it into a gearhead motor just remove the motor from the pcb board and solder two wires to motor leads it will connect to the dmd unit that way .

Panther G,
If you don't wish to reinvent the wheel, our fine friends at H.E.A.T. Armor club have already worked this out. Here's a link:

I've successfully done it myself on a JT using their instructions and a micro-servo. I do recommend using a camera positioner switch instead of the servo rate reducer. (I don't think this was available when that post was made. I'm sure they're using it now). http://www.dionysusdesign.com/produc...4ca9c40581fb2a
Works great.

Here is a link to the article I put on the H*E*A*T site

If you use a 6 channel radio you can move the mgun channel from the DMD to channel 5 or 6 and not have to use the dual extension.

I used the H*E*A*T* instructions. While doing research for the rate reducer I ran across the Cameral Position Controller from Dionysus. With the H*E*A*T* mod you need to use a ratcheted stick, or the gun will always return to the neutral position. I use my ratcheted stick for my throttle, so I had to find another solution. Not only does the CPC reduce the servo speed, but "When the stick or switch is in the center position, the servo does not move. When the stick or switch is moved to one side or another, the servo will slowly move to that position. When the camera is pointed in the correct direction, simply move the stick or switch back to the center to hold the servo at that position." This means any sprung stick will do.
Good luck

forgot about the ratching of the control sticks I have all mine setup to self center in all axis ...so if I take my hands off the radio I know the tank is going to stop. This is because my wife says I have AADD but she just doesn't underst.... oh look a chicken!

Hi Steve, your mod looks like it works well but I noticed that the gun cannot depress below level at all. this really isn't the best result. I can see also that you lose the recoil function. I am really looking to keep the full functions but want to get away from thr troublesome Tamiya units. i want to use a servo on a few projects but need to know how people have worked around the self center issue and how too slow the servo down enough for realism. I may give Brett a shout from A.C.E.. I think he has done the mod and may be able to help.

Hi Gregg,
I just sent you a reply. A servo delay and a Y connector are used for this modification. I'll show you at the NEAD battleday tommrow on Kim's Pershing or my Panzer III. Brett plans on coming up from Delaware as well.

Thats great Bob. I ordered the Y connector and the dual rate camera servo controller. It seems to me the best way to go, so we'll see. See you tomorow.
