This is a test of the nosewheel and door on my Chris Golds RC B2 stealth. The retracts are E-Flite servoless retracts. The doors servos are mini retract servos, LSX or Logic RC 260R, hence the slow speed. The sequencing uses SM Services units, of two types, one to control the open down gear close on the main door and the other for the nose door. The one controlling the nose door will be tied into the main gear and doors as well when those are completed. I still need a bit of work to put some stops on the doors to stop them shutting too far.
