well temperature and humidity do come into play............I always like to let my Heli sit for a while before flying, this helps the Heli's electronic's to adjust to the outside.......As far hovering good oneday and the next not so good..........hmmmmmm let the chopper aclimate to the outside.....make sure batteries are all up to par.....I always like to pre-test setting holds on flat surface......run Heli up to 50 % throttle...just before lift off.......make sure all settings are right....pitch, gyro, etc..........................happy flying........
