I've done business with Bob held on several occasions. To say that he's slow is an understatement of truly epic proportion (extra points for anyone that can tell me where I stole that line).
Bob is honest, generous, truly dedicated to the hobby, and I won't ever do business with him again. It's like spitting into the wind. Great guy, though.
I hope he gets it together for both you guys having issues. Please don't let it discourage you on the hobby. Most guys are a joy to do business with. For future reference, it's always a good idea to ask here before spending money with a private individual like Bob. Some guys have better reps than others, and someone here has dealt with just about everyone doing RC Tank business.
