Last crawled date: 5 years, 8 months ago
This is a work in progress main gear set for the RMRC 1.8M Skyhunter.
1/1/2020 Update - fixed holes so they can pass M3 hardware on main gear, also created larger holes for Dubro stub axles.
1/8/2020 Update - Added V2 STL. Extended the lower bracing further down the gear to improve stiffness, made the holes in the cross braces 1mm larger to better clear the heads of the M3 hardware that needs to pass through the cross brace. I also lowered the gear / raised the axle by 5mm.
1/12/2020 Update - Aded V3 STL. Modified V2 model to V3 by enlarging the axle stub holes to accommodate the Dubro 247 stub axles. These need a 3/8" hole to bolt on and the prints were sometimes splitting on layer lines when I drilled them larger.V4 coming soon once I verify a 8mm hole will work.>
1/12/2020 late update - V4 STL added, 8mm turned out to be a really nice snug fit for the Dubro 247 Stub axles. Unless some other issue comes up, this will likely be the final version of this design.
For the nose gear I'll either use a skid or another STL I've found on the Finwing page:
