the retracts are servoless with an over current cutout, what i have found is that they retract just fine if i
raise them straight after takeoff, or before i get too much speed. i figure it must be airflow under the wing
creating an air pocket or such which in turn stalls out the retract unit and shuts it down on overcurrent.
you will notice that on about the third circuit i throttled back, and dropped the flaps to slow her up further,
i then retracted the gear and they both went all the way home. i only have a few flights on her so am still
discovering any idiosyncrasys and this seems to be one of them. doesn't matter, looks far cooler when you raise
the gear just after you lift off anyhow
