Hi everyone

I really need help.

The turret will not rotate, no recoil or flash for main gun and mg, plus no sound for them. Apart from that it works fine.

All the wiring is correct (I have checked a number of times).

I have no idea what too do.

take all wiring out,then re do everything,i am sure its a wiring issue....

Just tryed that, its still the same.[]

The rotation unit works but the turret does not move.

I used the self check system, the gun moves back then forward and flashes (MG also flashes). Does that mean anything?

have you reset everythig?

Yes, I did.

The mg works now but the main gun still does not.

Hi,What Radio are you useing???? I herd of problems trying to use recievers with more than 4 channels ,dont know for sure,all my full function Tanks are over sea japanese releases,that come with futaba radio systems all set up already.Try a radio like Futaba Attack 4ch (ground) thats whats included with the Tamiya kit I have.Also check the Trimms and try setting and resetting them.
let us know how you make out...

I have a Futaba Skysport 4YF, the reciever has 6 channels.

I took a good look at the turret rotation unit, it looks like the gear does not always connect to the turret ring and when it does it can't move it. Also when I take the turret off and try the rotation unit it works fine.

The unused channels on a receiver with more than 4 channels will not interfere with the channels in operation. Otherwise, there is a bug that will cause disaster in the air for those who fly RC airplanes.

ahh.....I guess that would be a problem for people who fly....I wish I could,but with my luck I better stay on the ground for now.I hope he or someone figures out the problem........Ill go back to the drawing board

I have built the Tamiya Pershing, Tiger I, the King Tiger, working on a PZIII conversion to Tamiya f/o and my Panther should arrive next week. The Tamiya builds had turret rotation issues.

1. The stock gearbox comes with a clutch gear which does not provide enough torque. You can glue the clutch gear solid to defeat the slipping/no rotation issue or Tom sells a replacement gear for $9.00 that will also fix the turret rotation issue. Do not grease this unit. Visit turret gear ref: http://tomsrctanks.com/id16.asp

2. Better radio choices for no problem operation: If you are new to Tamiya RC tanks, use the Futaba AM 4 Channel Attack Radio, visit Tower Hobbies, or if more advanced use the Spektrum DX 6, go to: http://web.mac.com/ethandunsford/iWe...io%20Room.html

3. Try this: Using your Futaba Skysport 4YF: first setup, program/operate the DMD units completely out of the tank, very important. (I tried to use this radio in a Tiger I a couple of years ago, and could not get it to work well. But I know other people who use it with no problems).

Lastly, Tamiya USA does not recommend 6 channel radios for use with the f/o DMD units. Good luck.

That sounds like the problem I have.


I did try that but I might have done something wrong.


I wish I knew that before I got it.

Thanks for the help everyone.

Please show me where Tamiya USA says that. I'm looking at this link:

I don't see how having two extra channels would cause problems, unless one plugs into them. There are many people in this forum who are currently using 6-channel transmitter/receiver with F/O DMD units without any issue.

I've been using the Futaba Skysport radio in my tamiya pershing with no problem and using the reciever that came with it.

Your both kinda right, but the Pershing DMD units are different than the Panthers.

I saw at least 50 tanks at the last SCAT battle day and true most used some sort of Futaba Skysport radio...but there may be some type of glitch with some Tiger DMD units...read on.

Like I said, if you are new to Tamiya rc tanks:

Ref: ((I tried to use this radio in a Tiger I a couple of years ago, and could not get it to work well. But I know other people who use it with no problems).

Lastly, Tamiya USA does not recommend 6 channel radios for use with the f/o DMD units. Good luck.))

What I did was call and write Tamiya USA in Southern California and ask to speak to an RC tech about a Tiger IE DMD setup problem. I had run into the same problems as BlizzardBeast's Panther with my Tiger IE build (even sent Tamiya USA both my DMD units).

The Tamiya USA solution: they told me not to use a 6 channel FM receiver and to use the Futaba Attack Am radio if I wanted things to work well and that my Tiger's DMD units were OK. So I changed radios and everything worked great.

Interestingly, I used a Futaba Skysport FM radio with a 4 channel receiver in my Pershing build and it worked just fine running the Pershing, go figure, but ask the Tamiya USA tech why, not me.

Anyway, the Tamiya USA tech solution worked for my Tiger and the BlizzardBeast's Panther uses the same Tiger/King Tiger DMD units and that is why I offered up this solution for this problem.

The Pershing in this case has nothing to do with the Panther issues as described in this thread, different
DMD units.

I didn't read anyone offering any real helpful solutions to get this Panther running and that is why I took the time to offer some helpful tips based an actually building, trouble shooting and running these models.

My Tamiya Panther should arrive from the Tank Museum tomorrow, hence the interest, so good luck to you BlizzardBeast. Sell your radio on ebay or see if your supplier will exchange it. Regards.

I did some reading on Tamiya website and can see how the digital trim levers can affect the firing of the main gun and machine gun. With mechanical trims, one merely slide the trim levers all the way and quickly push on the right stick to fire the gun. One can't really advance the trim all the way in one push with digital trim.

It is not clear to me if when you set it up OUTSIDE the tank if it worked or not. If it DIDN'T, then it is probably a radio / DMD issue. Do you have another radio you can use/borrow to benchmark against?

If it DOES then maybe there is some with the way you are running the antenna / servo wires and all the other wires. Can you post any shots of you tank with the radio installed?

I had a problem with my pershing when it was new, it could notate the turrent, I found out that the turret ring is getting caught by the fet fins on the DMD only after I glued my rotating gear clutch. Maybe you can do the same, how to check this is remove teh turret ring from teh turret set it on the rotation mechanism and see if its catching on anythingto prevent it from turning. if it turns freely, check the ball bears or what ever mechcanism that aids in turning teh turret to see if they turn freely. if all else fails, make sure your wiring do not get snagged.

It did not work outside the tank. I don't have another radio and I don't know anyone who would have one.

I don't have a camera.

@pcomm1: I got it off ebay and I also got my panther from there too. I could not find the Futaba Attack on ebay so I got the Skysport.

Another cheap radio to try is the GWS GWT-4A 75Mhz FM. Both of its sticks are spring-return to center.

Try Tower Hobbies for a radio: http://www2.towerhobbies.com/cgi-bin...I=LXBCP2**&P=7

Good news, the turret now rotates.

Hey..Thats Good News......are all your problems solved??? If not , what problems remain???? also can you list your problems you had with any solutions that may have worked,as to maybe help others in the future...........

Tamiya instructions tell you to plug items in 1-4 but, to solve your problem plug them in like this: 1-4, 4-1, 3-2, 2-3 and this should solve your problems. Left stick is throttle or forward/reverse/left/right and right stick is for moving the turret and raising and lowering the gun barrel and when the trim is moved up or down firing the cannon or MG.

I have a number of transmitters lying around from purchasing garage fulls of RC stuff and I just used a Futaba skysport 4 airplane transmitter and a Futaba df 127receiver that I had a few of already on hand. I had problems with things working and switched the plug-ins as listed above and everything worked fine. I also modified the left stick on my transmitter so it would return to center. You need a spring and plastic lever from another transmitter to make this work. I cannabalized a Futaba Conquest and the parts fit and work fine.

The best transmitter solution though is Richard L.'s setup. He has a DX6 and uses it to run all of his tanks. I would however, love to know how he modified his Hung-Longs for use with his DX6. Until I get a DX6 or 7 I will keep using the old Skysport 4 as it works just fine.

I owe you big time, been beating my head on the wall trying to get this Tiger I to work and you solved it for me.  Can't thank you enough for posting the fix.

Just thought I would add a problem I had as well.

I have two quite old (5 years) Hi Tech Focus 6 and 4 channel radios.

The 4 channel operate the gun no worries, the 6 channel just won't do it?

Tried swapping over the receivers, adjusting trims every combination possible!
The 4 channel always works, the 6 channel no way! Couldn't for the life of me
work it out, still haven't?

Now what we have here is two radios from the same manufacturer both of
which are the same age, yet one operates the gun fine the other no way!

Does anyone know why this would be the case?
