RE: F18C EDF RTF ( ExceedRC) Fan problem.
Hey congrats!
Yup it can seem rather pitchy on high rates.
That's why I prefer to tackle as few things as I can on a maiden.
BTW: Did you install the two other servers or just go with the default?
Also did you notice that it rolled on you and you had to add right trim to level it out?
Re: Gear
The gear has a retaining hole that prevent the rear gear from shifting forward and back.
Then the two straps are used to hold the gear in place.
Once done they should not move or shift.
