I resurected my RC Car today. I replaced the shunt resistors and servos. I also had to repair one servo whos limiting wiper wasn't even touching the final output gear - so it was just continuously grinding away agains the mechanical limit (a lug on the final output spur). It turns out that the other radio and servos are OK but I can't mix them - they aren't compatible. I only have one set of crystals though =/
I found a perfect double-tapped resistor in my collection of bits and pieces recovered from old TVs and Stereos. I soldered that in and fitted a spacer to the old mount and it fits clsoe to perfect. Although I can't put the body on properly anymore =/ I will have to remedy that with some creative mounting or some agressive grinding =)
The buggy looks like something out of mad max - all battered and beaten, looks like it's cobbled together out of bits found in the desert!
I also had to repair my charger. It appears to be working but doesn't indicate it is. Well it pulls the current and the battery gets charged so it must be. All the voltage measurements I took worked OK. There are a few blown resistors. Perhaps a short inside - the resistors are only related to the indicator LEDs. The charger is a aligator clip type arrangement designed for a car battery. I hooked it up to my trusty Manson Power supply which can deliver up to 25 Amps at 15 Volts. It's going to come in handy later when I test motors and what not, though they will probably peak above 40A...
Speaking of repairs I came across two beautiful repairs I made about 10 years ago!
