-in the process of soldering deans connectors to my lipos...i had BOTH wire ends exposed and when i put them down onto my METAL table.....i had sparks galore along with a shorted out 4th cell in a brand new 5s lipo pack

-deans plug soldered on backward on the esc

-buying a blade cp pro right after i just bought a blade cx2 thinking i was an expert in rc heli's after that...well...1 month and 100's of replaced parts later it ends up going back onto ebay...lol

-numerous stripped hexes due to low quality hex wrenches leading to drilling/dremeling to save an $80 chassis..

-series is NOT the same as parallel connectors....that one definitely sucked...
