I opened up my Roboquad for his yearly routine maintenance. This would include applying lubricant to all his mechanicals, checking wires, etc
I noticed two ciruits with quite a bit of corrosion on them. One looked like it had been burned ( a tiny SMD service mount or crystal) by someone trying to replace it, who did not have the right service equipment to perform the ciruit replacement.
The only reason I'm not concerned to much about replacing these circuits is, the rest of the main board is perfectly good condition, and Roboquad has been like this ever since I got him, hundreds of hours of use with no problem. The condition of the circuits haven't gotten any worse. If fact the circuits seem to be operating just fine as is. I'd rather not attempt repairs on this one. Since he works fine. He's pretty delicate inside, and the crystal mount being so small, I fear doing him more harm than good.
However does anyone know where I can get a spare main circuit board for a Roboquad? I'd eventually like to replace the entire main board in him. Until then, he seems to be operating just fine as is, program memory and all, no problems.
