I saw your video and your solution to the binding issue seemed great. Later I was thinking how robust the blocks that you took out were. The first landing will rip the servo arms off as they will take the direct landing load. I hope I'm wrong but if that is true I hope you haven't build yet.
Is it possible for the building of this system to be shown in full. I have the plans for a Curtis's SBC 3 Helldiver and would like to build the retracts to fit
Ryan, SUPER IDEA. I LIKE IT. However, the one possible issue I see with this arrangement is that your servo outputs are subjected to not only the weight of the aircraft, but the shock of every landing. Your thoughts?
Fantastic! I just spent a good 40 hours getting my Robart Wildcat gear working well. I think your servo conversion solves all the inherent problems with the gear.
man this is awesome !! i wondered if one could use retract servos to get them up and down this is the only thing that is holding me back on the wild cat is retracts
Reallu nice job Simple and effective. Tried to find a VIDEO of the Retract system on the Full Scale Wild Cat but no luck but some showed the wheels retracting but not the Mechanism. I remember reading it was Hand Cranked by the Pilot and took about 32 turns to achieve full up or down. Thanks again for the Video. Love the Finished Plane.
Yes, I remember that it was hand cranked up and down by the pilot but I didn't remember that it was required 32 turns fully up and down. This means that the poor pilot had to cranked like crazy meanwhile he had to land or take off. He must had an oversized arm, lol...
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.
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
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..
hey ryan how did you find the build quality of the kit ? did you had to remplace some item that was not that good and how did you end with that color can you order it with different color thx
nicolas byron The build quality is excellent. The only item I switched out was the uat fuel tank, which they recommend doing with larger engines. As far as the scheme, they have custom schemes like this available upon request as long as the factory is familiar with it. The list basically comes from the schemes on the Bvm jets website I believe.
