My biggest issues so far were with hardware from one of the cheapest sellers online of RC planes. However I knew to expect this from reading the forum. I should have just thrown it out, but I tried to salvage bits and pieces creating a massive headache and hours of extra work.

Everything else I've had so far has come from a major distributor and things generally work out OK. My hand fuel cranks are pretty much junk though - seems to be a theme here - not sure if it's 'cause I went with Tower brand.

The charge jacks are a bit tedious to setup properly. There is such a fine line between getting the plug in the perfect spot against the tiny little stop, and also tightening the screw enough without crushing the plastic. I ruined one and learned from it, the rest have all worked out very well.
