Nice units, sorry to hear the troubles you've been having, personally, I'd go away from air, I have been using "Actuonix" linear actuators for some of my builds and they are great, look into them. You might be impressed. I used one for a main gear door, mixed with a curve, and over riden by another channel as it works as air brake aswell. Lowers fully, gear down, door half closes. Totally variable, as a normal servo is. I'm now playing as using them to push a long small cylinder into a larger, shorter cylinder to work as a force multiplier, small electric servoless hydraulic system for main gear actuation. Scale size rams. With close to 300psi at the gear end, same principle as a brake lever on a motorcycle. Or car bottle Jack, So far so good, and very lightweight. Using carbon tubes, alloy for the spares, and very light oil, using water and glycol at the moment through standard airline Just and idea
Hi Russ, this is actually my fathers. I'll forward the info. Here is the latest update. Thanks for watching. ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-3dPWVu_dkKI.html
Why can't Robart get the geometry right? seems stupid to have it bind and need to loosen the mounting bolts... that's screwed up.. glad I did not get them.. I've currently got about 800 dls of defective struts that I need to return..
Hi, this is my fathers and will be installed in the airplane soon. Here is the latest update. ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-3dPWVu_dkKI.html
I'd replace the air system and that FINIKEY VALVE with an electric motor or even a SERVO and be done with the major problems forever. JMHO. Or just replace the Chains and Large SPROKETS with servos attached to the Pivot arms. Of course it ain't scale but you don't see the mechanisms anyway.
