Main landing gear retract ram rear mounting block. This was a machined forging. Some tricky soldering will be required to get this finished.  |

Do the black and red wires indicate that the undercarriage will be actually retractable through electric means?

Hi Dave, the last image above is a link to a video, showing the extension movement. 15 seconds for full extension of the ram = 15 seconds for full retraction of the gear, hopefully. I'm looking to add some microswitches to delay the retraction / extension sequence of the second leg. |

Good Grief(2)!!
And here I am mentally envisioning the fold/rotate/retract sequence of a 1:1 scale P-40 and wondering why Grasshopper isn't doing one of those instead...!! This just keeps getting better!

This just keeps getting better! A significant lack of funds is in the way.....If I ever win the Gold Lotto a 1:1 rebuild would be considered. |

My mind is spinning...it'll probably explode when I see the completed assembly in action! Wow, Peter!! Bravo!

More progress today....  Starboard main landing gear retraction pivot mounts.  This angle is to account for the 6 degrees of dihedral. Looks a bit strange, hopefully it all lines up correctly when everything is riveted together.  Upper retraction arm.  |
