RE: WALKERA 37
No still have not mustered up the guts to do it myself especially after reading the whoas of embpic1. This will be the weekend as long as taxes go smoothly. I had to re-set the main blade tracking after replacing the main blade holder but she seems smooth as silk on the bench. I only get about 3 minutes and 45 seconds at hover power, held to the bench of course, with all of the stock stuff so I will have to make sure my RC friend keeps it short. It's clear some upgrades are in order although I have not had any of the reported servo problems. When Hooobby.com sent the replacement parts the main blades were missing. I emailed them and had them in 5 days at no charge, no questions asked so kudos to them. I intend to take video of the first flight and will post it, crash or not. Have fun.
