What if?
 

I have a Tiger with smoke and sound.

If I purchased a main receiver board and a smoke and sound board and fitted these in a boat, would they work from my present transmitter?

RE: What if?
 

As long as the crystals matched it would not matter what it was installed in and should work fine.

RE: What if?
 

I thought the S&S transmitter was different?

RE: What if?
 

Are the receiver crystals the same plug in type as on other R/C receivers?

RE: What if?
 

The S&S transmitter is generic and only requires matching crystal sets to communicate. The NON S&S transmitter IS completely different (internally) and uses different protocols to communicate.

RE: What if?
 

The Heng Long crystals are pretty unique to the Heng Long RC range (I've heard that some people have had limited success with non HL crystals, but overall the majority don't work).

RE: What if?
 

I suppose rather than looking for the crystal on the receiver it would be easier to change the one on the transmitter. (shows how much attention I have paid to the front panel on the transmitter until 10 minutes ago)

RE: What if?
 

The crystal on the receiver is socket mounted on the smaller PCB. It will have the ID number (01 to 04) and frequency printed on it. The transmitter crystal MUST match the receiver crystal for it to work.

the one without the metal shield at one end?

RE: What if?
 

Yes, that's the one.

Just looking of a pic of one on ebay and I think I can see where the crystal fits.

RE: What if?
 

Below is a pic of the HL Receiver board, the smaller of the two boards needed for "S&S". It is powered by the data cable, provides input signals to the main function board, and the antenna also attaches to this board.

I have fitted an RX14 S&S set into my 1/350 scale Bismarck, proportional speed in the water is nice for small areas :D

RE: What if?
 

Seems a cheap way to get a multi function system.

Smoke, sound, and I am sure use could be found for the gun firing and turret control motors.

You could buy the complete tank and resell the tank body bits on ebay.

RE: What if?
 

How did you wire up the Left Right?

RE: What if?
 

Motors, or rudder control?

Easiest way is keep the left-right motors for the propellers, and use the turret power feed (left stick right/left) for rudder control. Then you still have 4v feed from the elevation and 7v for the airsoft feature, as well as port for power extra items like smoke and barrel LEDs (if its armed)

RE: What if?
 

Does this give propertional power to the motors. i.e. more power to the left motor when turning right and more to the right when turning left?

RE: What if?
 

Yes, for turning, or for proportional speed. I have a short vid from a while ago of my Bismarck in the bath while I was doing some testing... ([link=http://members.iinet.net.au/~wackywheelz/rc_bismarck.wmv]video[/link] | [link=http://members.iinet.net.au/~wackywheelz/rc_bismarck.jpg]pic[/link])

No aerial or workable rudder was installed at the time (out of servos), so it was just proportional single-motor tests. Also, I had just poked the wiring into the battery plug, and it came loose towards then end then slipped out totally at the end of the video.

RE: What if?
 

You need a bigger bath.

Or use the bath as a boat hull!!!!

RE: What if?
 

I shall have to take my Tiger apart to see which plugs go where.

RE: What if?
 

with servos?

RE: What if?
 

Yep, using them as a basic motor+gearbox powered by the HL board.

RE: What if?
 

Thanks.

Slowly getting this together now.

RE: What if?
 

What size battery pack did you use?

I wondered if I might go up a bit from 7.2v.


Soldered some wires on the board I am going to put into boat but what confused me is:-

This is on the Tiger.

Neg and positive enter bodyshell. Neg goes to the control board. Positive goes to on/off switch, but there are three wires on the switch. One red positive from battery, one red out to board and another RED out which is connected to the NEGATIVE on the board.
A more knowledgeable person said it is a single throw double pole switch (I think) ,but he couldnt figure out why it is wired like that and he designs and makes his own PCB's. He said it must be for a reason but as he's not into R/C he wasnt sure.

I connected my new board to battery by sticking wires into plug, connected multiplug to tiger and everything worked OK.

RE: What if?
 

The wire that goes from the switch to the receiver board is used to discharge static electricity. When working on the tank it usually results in blowing a board so we leave that wire off with no ill effects. I'd stick with 7.2v battery packs, don't think the boards will handle much more.

RE: What if?
 

I have another set of boards, which I have bought to put in a boat, but they didnt have any wires attached so I had to pull the Tiger apart to see what went where.

I think all in all, the best (cheapest) way to go if intending to use Heng Long gear in a boat is to buy the complete tank and control gear to start with.

I should have costed it up better before I started buying bits.
