T-90 RADIO INTO STD H/L TANKS

[HERMAN BIX]

Hi Guys.
Now I know there has been a bit covered off on this but as I fall into the 'special needs' dept when it comes to electronics, I am going to ask for you patience and assistance.

so, the 8-pin plug on the normal setup is not a straight swap.............I get that.
So, can this be made to work if I join the wires outside of the plug colour to colour ?

I got the sound active to see what it was like and my god, what a contrast to the usual.........
I just doubt my ability to get the functions working is all.

Hermann, see my post in the other thread, if this is what you are after. let me know. Unfortunately I haven't a clue how to get the airsoft working during a swap, though I may be able to figure it out. All of my modelling gear and parts boxes are packed ready for a house move, so I can't play around with components and wiring to see what needs to be done, and I may not be able to for a couple of weeks.

Hi, HB..well if you really are a 'duhh-brain' when it come to tank electronics (though I doubt it) I've put some thought on the subject (no, ..not your claimed disability ),, on the end of the other related thread, thus:

Get some coloured pencils. A basic set will approximate the colours of Taigen/ HL wiring. Then a lined notepad. Begin by tracing lines from components (e.g. Airsoft unit..and known connector colours
back to reputed connector position on the RX-18. Then use the probes of a cheapo continuity tester to ensure that the life-juice is getting through from one end of that circuit to the other. Repeat for all other individual units.
Done systematically, even someone under the influence of a crate of the amber nectar should be able to complete a basic working diagram. This process works for me..although it's without the nectar.

Thanks mate, but Ive actually got no where to start outside of the motor wires.
My Jagdtiger is gutted, not even an on/off switch............

The test I did on the unit was to put battery into the correct socket, and speaker into its socket.........and that was well good for me to play with the sound switching and other functions.

I wont have a turret to turn, but I am determined to get a form of recoil going.

[wibblywobbly]

I assume you are aware that the only way to get the recoil is by installing an aftermarket board with servo support, or indulging in witchcraft to get the airsoft unit to do it?

There is an airsoft with recoil unit out there if you can track one down though?

For a recoil, you could get the Taigen plastic Tiger 1 turret; the Airsoft model with recoil unit)...here:
http://www.taigentanks.com/taigen-tank-parts/tag120700 and strip the barrel and recoil mechanism, out of it. Imex/ Taigen Tanks of Florida sell them, but maybe they could be ordered elsewhere. I know rctank.de sell the servo for it, so maybe they could order the remaining parts. Maybe Forgebear too.
Florida is a cert, though..but could be pricey with postage.
Here's 'Imex Erik's' take on how to strip the unit down. He sounds a tad nerdy or geeky , sometimes, but that is offset by a concomitant wealth of knowledge:

Ok, have now established that in a Taigen electronic set up, my hardware works.
With the new T90 electronincs-it wont.
Only talking the recoil & elevation.

Have taken a wire off the negative battery pole to connect the unit, (this works in the taigen) and run the 8 pin cable from the receiver to the correct T90 plug socket.
The only 3 position plug on that plug socket takes the taigen recoil unit plug (black-black-red) and I have tried both combinations of the black wire position, but not the red one.

What are the dangers of removing the terminals out of the plug head and placing them directly onto the exposed pin connection points on the various plug sockets?
I was optimistic of the genuine 8-pin plug & cable being the silver bullet, but it appears not to be the case.

Only other thing I can try is to swap the 8-pin cable into the Tiger & see if it still functions.
This would confirm if the cable is the problem or not.?

Me careful with that Herman I actually damaged a board doing just this. I was however playing around and had not attempted this with the new board, but a spare rx18 I had in the workshop. I accidentally touched two and lost some board functions but not the sounds.

[B_Man]

What colour are the wires on the main cable that are connected to the 3 pin plug?

Just got back from Switzerland yesterday, Herman, where it wasn't advisable to sport external genitalia. The temp. dropped to minus 9deg c. near the range where I go shooting with my son.
I almost turned into an icy human stalagmite. Lots of that deep white powdery stuff (not the sort that goes on dollar bills up the nose )..

Anyway, my brains still a bit numb, so can you help me by refreshing the thread. Are you attempting to fit the T90 MFU and attendant 8-pin connectors into your Jagdtiger with a standard BB setup, or did have you managed to get the Taigen airsoft barrel recoil setup in there? Standard BB setup would be no problem as the latest T-90 MFU is largely the same as the earlier model; it's just the revised 8-pin connector you need to be wary of. If you have the Barrel airsoft recoil unit, it will only work with the Taigen MFU and not the T-90 with the tasty effects. That's because the firmware (electronic
instruction code) embedded in the Taigen unit differs from that in the Standard HL unit, and the HL t-90 unit. The T-90 should trigger the airsoft, and sound but will not trigger the recoil. You need an IBU for that. Even the Clark TK22 (I discovered to my dismay) couldn't operate the Taigen Airsoft Barrel Recoil System.
Trial and error connections can be a problem with circuits containing diodes (i.e an LED). Diodes are polarity dependent, and can blow with reversed wiring. Ordinary +/- switches are ok..the worst you can do there is make the component run backwards (elevation unit, rotation unit etc.).
Directly connecting wires works so long as they're the correct wires. Where two wires share a common connection...you might have a problem. What I do for experimental purposes is use these, as they're an easy bridge between existing connectors. and don't involve dismantling the JSTs. (Hard if you're cack- handed). You'll find them in OZ at: http://www.pakronics.com.au/collections ... and-probes
Best of luck, mate and belated HNYs..
