Replaced one motor/arm (Vertigo), reattached dampeners, inspected closely for any possible issues, flew it tonight just to test, seems ok; miracle the camera wasn't trashed, but can't find anything wrong with it so far. I haven't been keeping track of upcoming updates and such. Is there a suspected hardware issue with the GPS or is this more a firmware fix? Toilet bowling shouldn't be an issue these days. Man it would be nice to have a schematic of the of the board and specs of the sensors/GPS.
