      Hi guys, can anyone help? Here s my story; saw Iwaver 02 on Toyeast website $49.90 plus express shipping $90 (about ?47) had to have one! Four days later bingo I had it! Well pleased- great car with good performance and awesome transmitter. Next step- start dreaming about upgrades, Ford Focus shell, ball diff, bearings etc. Then I decided to fit a nicad pack in the transmitter, which I already had in my futaba four channel transmitter. Then fizz, smoke, dead transmitter. What a dipstick!- I didn t check the polarity of the two pin plug on the nicad pack and it was the opposite way round.
      When I finally stopped kicking myself I decided to open up the transmitter and see what damage I had done, it was soon obvoius that I had, ahem, slightly modified a transistor on the board nearest the crystal. My problem is that I cannot read the part number/ spec of this component to try and find a replacement. Is anyone out there with one of these willing to open it up and have a look for me please? Any help would be massively appreciated. I have taken a couple of photos to try to show the specific component.

      sorry, i dont own any i-waver gear but,

      in the meantime just take the crystal out of the iwaver tx and put into your good futaba one.

      Thanks Priest, that is excellent.

      “May your diff remain ever lubed and your ballraces shiny.”

      P.S. I will post when I manage to source a replacement just in case anyone else is as stupid as me!

      Thanks,

      Martw.

      Hi, martw
      I just had the exactly same problem as you on Iwaver transmitter. I put the Futaba battery pack without checking polarity and blowed up the 1702N transister.

      I admit my mistake, but they should not use Futaba connecter and switch the polarity, I guess.

      I tried to replace 1702N with a NPN transister and changed all the chemical capacitors, but still have no luck yet.
