Electric Retract Set, T-28 Trojan, TopRC Model

Very robust and nicely constructed.
There is also a great sequencing box that makes hooking things up simple.

Door servos won't work on the controller. Put a message in to Gator but haven't heard back yet.

Have not flown the aircraft yet. Still working on installation. The lubricant that comes on the units is really more like rubber cement. Once cleaned and greased properly they work well. Spring stiffness will need adjustment once I get the total weight. I have operated many times working through gear door installation and they have performed flawlessly. They also appear to be very strong units. Nosewheel steering could use some better engineering.
