Default Missing something??

Trying to save a few cents here and there and now I'm in pickle. I bought a Tamiya Sherman vesion came with metal chassis, running gear and motors. I've picked up the following:
Tamiya DMD control unit T-01
Tamiya MF-02 Multi function unit
Associated Electric receiver TR203A (2 channel, 27 mhz)
Matching 27 mhz crystals in transmitter & reciever

Nothing happens. I have power to the DMD units T-01& MF-02, verified via LEDs. I've plugged in the rudd & throttle from the T-01 into the receiver but no commmand inputs are working.
Thoughts? What powers the receiver? What is this newbie missing?
Thank you
Mark

Never mind....found I needed to power the receiver from the MF-02. Any ideas where to get an appropriate cable from?

You dont need any additional cables. just p[lug the appropriate leads into the correct channels on the reciever. If you power the receiver seperately you will burn out the MF unit.

Panther,
Thank you for the input. Are you saying that Rudd = Ch2 & Throttle = Ch1??

Well it all depends on which stick you want to drive and steer with. You could set it up in 2 modes. 1 I think puts the drive functions on the right stick, mode 2 reverses this on the left. The receiver needs no out side power source as it is supplied to the servos/ motors from the Multi function unit. So how you use the channels is up to you.

Did you say you had the Tamiya two channel adapter? I usually scavenge mine for the plugs.

One of our club members uses a two channel setup on his sherman and from what I see, it is a pain in the butt. Spektrum DX-5e or Futaba 4yf 2.4ghz are only $95 new and may save your sanity.

OF COURSE, THIS IS ONLY MY OPINION. Try a local hobby shop that specializes in R/C, many former FM users are trading in their radios for 2.4ghz and the used equipment is real cheap!

Another thing to look for is the surplus DX-5Es from the larger Park Zone RC planes. I picked up a radio and reciever for $80 that came our of a Corsair. The buyer had a Dx-7 and got a deal minus the single reciever DX-5.

Just remember the T-01 is only a two channel controller. The rest of the T units are four channel for "full option" tanks. Just count the receiver wires. Bob

Understood. I bought the 2 channel receiver but it's still not talking to the transmitter I made sure I had the same crystal set. The Transmitter is from my Matorro Sherman ....would that have anything to do with it?

Yes they are not compatable at all. The matoro radio is not a hobby grade radio. Get the futaba 2.4 Skysport. I have 2 of them already and they work fantastic. for 99.00$ at Tower Hobbies it comes with the receiver.

Hi Mathom,

Mark, you are trying to make orange juice with oranges, apples and grapes. The two channel 27 Mhz receiver (AM or FM) will run the T-01 only and nothng else. It will not to anything with the MF unit. The MF requires a communication cable from the T unit and yours is not capable of performing this feature. Did you get Sherman from Daveforwhat? If it is a two older two channel Sherman kit it will need to do several modifications. To add on the traverse and elevation since that tank kit was made before these options were available from Tamiya and it is not a "full option". The mounts will not even be there and you are probably missing the ring for the turret traverse. The FO Sherman if a four channel tank where the radio receiver has at least four channels and takes its power from the four channel DMD unit. All other uses will require a separate battery source. DO NOT use any battery in the receivers B port when using a four channel/wire Tamiya DMD unit or you will overpower it and ruin the device. The transmitter must match the receiver or else one is speaking German and the other is speaking Greek. My earlier post shows how the DMD & MF are paired up. Some mix and matching can be done but none involve the T-01. The only T unit that is self sustatining it the Leo T-07 and it is very expensive. I'll include a photo of how the Tamiya system looks installed, It appears that you will need a 4 ch receiver with matchign transmitter and crystals, another T unit, comminication cable, elevation and traverse unit, speaker box, strobe unit for the barrel (optional), LED for machine gun (optional). Do you have a Tamiya manual to guide you?
I hope this helps....Bob
