update,
i scrubbed everything and started afresh, reflashed the two boards with the updated firmware, used new recivers, and new hobbyking 45 esc's, fully charged batteries and told the dog not to disturb me for a few hours.
recoded everything from the radio to the opx
both boards are now functioning as they should. i have no idea if it was the esc's or recievers that were throwing a spanner in the works but at 9 quid each for the esc's im happy the boards are running again.
i even found the firmware hack to turn my other FS i6 to ten channel.
now to start looking at the mega i bought and see if i can get that to do the open panzer thing.
These boards must be pretty robust and virtually indescructable. which is a good sign (if they survived my tinkering its a good road test for anything)
thanks for the advice and support.

the radio was set up with the board in its previous incarnation (taigen later tiger 1)
but ill run through everything again as though its a first time marrying the radio with board.
the reason i thought about dual boards was back in the urks of time i experimented with eliminating track recoil with piggybacked rx 18 boards (one running the drive motors and the other everything else) which actually worked. and was easier than detatching a pin on the chip and rewiring it to something else, plus at the time i was upgrading to 2.4 from 27 so had lots of spare rx18 boards to play with.
i might purchase a couple of spare recievers and see if its that end of the process thats at fault. at least with flysky i can use them on other boards as the need arises.

elevation servo runs fine on both boards, turret traverse is direct from the radio as it ran constantly when run through the board.
i have no taigen sound card yet i did use a das micro for a while but removed it to use the taigen one when i grab one from forgebear
ill look into a sabretooth but just received two new 45 escs with the motors for the king tiger.
the arduino turned up and ill have a look at using that on the KT while i mess with the OP boards, which if they are a total loss ill switch to arduinos till a suitable supplier is found for the project.
looked at the pinout schematic for the arduino and it seems ill have to run pre 6.0 henglong wiring on the smoker which is just reconnecting both heater and pump wires to one plug. and recode the KT OPX to suit.
not sure about servo recoil on the arduino but ill work it out.
and the last time i got involved with eletronics at this scale was when i was 14 in the 70's and technology has progresed considerably since then and my eyesight is not what it used to be.
i did do a full inspection on the iffy board and saw no breaks, dry soldered joints, or physical damage to any of it. no sign of cooking, or damage to the pcb. i even cleaned the output pins (magnifying visor, acetone and stripped down cotton bud) so unless the main chip has given up the ghost nothing is visible.

no joy with the servo test, seems no signal is going through

the escs are the hobbyking reccomended ones and neither set work with the faulty board.
i have another esc from the landing craft project spare and i tried that one to no avail.
ill try the servo test later.
the woking board seems to have developed a glitch as well ( left track stopping after 3 feet of operation) but ill look at that later as its buried in the bowels of a 1/10 Pz38T

i have tried running direct from the reciever but it ends up using both sticks, which i cant get my head around.
if you can tell me the signal voltage from left and right connections i can run a meter across it and see if its failed.
red leds on ESCs are on constantly when i try to use it.
ive inspected the board for loose or bad connections, checked the copper strips and nothing is visibly amiss.

hello and thank you for letting me join the forum
i bought two TCBs with the correct ESCs a few years ago, im currently migrating them from the 1/16 tanks to 3d printed 1/10 scale beasts.
one despite all checks refuses to operate the ESCs.
it was working fairly well in the 1/16 taigen tiger. although it was intermittent with its ability to drive,
ive checked all radio (flysky) functions and even swapped radios with the working OP board, as they are both set up identically.
if theres no hope for this board, and they are no longer available. Im tinkering with the idea of keeping it in the 1/10 and piggybacking an ardruino board from the receiver to operate the ESCs and using the OP for all other functions. could this cause any issues that anyone is aware of?
