Hi
I've been working on electric retracts for quite some time now. They are in no means "easy to to", especially the wiring is very tochy and also complicated, as a simple "cutoff" will result in jamming. You need to electronically brake the motor the instant it hits the cutoff switch....not easy from the electronics-side.
I now have the prototype rig up and running, and will soon be building the prototype version.
The "ECU" will be about the same size as the JetCat/ProJet/Orbit turbine ECUS, and tests and calculations show that the cylinders will be "pushing" between 30kg and 100kg (66-220lbs). Gear cycle time will be around 2.5 seconds, with the speed being adjustable for each leg.
Will your controller have capability for external servo-drive hookup ? i.e if someone needs to sequence gear door opening & closing to the timing of the strut action, and you already have a controller box built in for adjusting the timing of the strut action, it would seem optimal to have gear door servo actuation (plus options to keep doors open or closed with gear down) built into the same controller rather than having to add yet another box to do that. Just a thought....
