sorry dude,
your right about some of walkera electronics, specially the servo's, but I think your wrong about 2'4 ghz. my walkera 60 is now 2,4 and the glitch's stopped the day I changed over, I used to get a glitch about once for every hour's worth of flight, I changed over at Xmas and it hasn't glitched since {if only I knew at the time all it takes is a squirt of silicon and a wire from the tail boom to the air frame}
What have I changed on my walkera 60, well it's been the radio + receiver to futaba 10C and R617FS and later the servos for hitec 65MG's, battery's range from 2450mah to 2200mah, all ebay cheapo's
bit's I wouldn't buy again are
cheap servo's, walkera, tower ect, if it can't survive the crashes it's false economy,
copterx 60 amp ESC, soft start is a jock my copterx 450 BA jumps 120 degrees every time it starts up,
RCmod's 280 carbon fibre main blades,

bit's I can't buy any more and would like to see for sale are the foam blades for the 60, it's a safety thing,
ps it's a good idea to do a list,
