Yes Retract servos have just over 180 degrees of travel.

There is a bottom line here and that line is its almost impossible for a newbie to mechanical retracts get it right with the wrong servo. Yes it can be done however your chances of success is almost nil. To make matters worse a common senario is you are going to have gear not fully retracting or pulling out on G load and you are going to be sucking up your battery supply with an overloaded stalled servo. Thats not condusive to the life or your airplane.


Do it right or don,t do it at all is very sound advice.
