F4F/FM2 Wildcat Landing Gear Update:
I have been busy with the Landing Gear CAD model for the F4F/FM2 Landing Gear assembly.
These images give you some idea of the progress to date. This is quite a challenging project due in part to the poor quality of a few drawings but also to the ongoing checking of dimensional relationships between the parts. Most notable is the forward Drag Link Support where you can see several red lines which is a visual indication of stated minimum and maximum tolerances. Also on this part, it is worth noting that the top pair of main holes are at 4.0625″ x/centres whereas the lower pair is at 4.1557″ x/centres…a minor variation but obviously critical dimensions.
The roller chain sprocket is a calculated profile to suit the specified roller chain; there is a smaller sprocket yet to be added to the Retracting Mechanism gearbox. This part of the project will take a while to complete and it will eventually also include the Engine mounting frame.
The Original CAD files for the Landing Gear are included in the F4F/FM2 Cad/Ordinate package. Drop me a line at hughtechnotes@gmail.com for more details.
I am building a modelairplane grumman wildcat F4F scale 1:5 . I would like to build the landinggear myself and searching for a drawing with dimensioning.
best regards
