SAC has recently issued a replacement cast white metal gear set for the new beautiful and enormous Kitty Hawk OV-10D in 1/32nd scale. Kitty Hawk will also be issuing this kit in an OV-10A/C version soon and this gear should work well for that kit as well.
Big Note Here: This is not an issue with the SAC gear but with the Kitty Hawk OV-10D. Kitty Hawk calls for the numbers on their instructions that don’t exist on the sprue runners. There is no “G” sprue. These parts actually exist on runner “J”. For me I found it easiest to just mark runner “J” to “G”. Disaster averted. I will be using the Kitty Hawk instruction parts numbers to identify the corresponding SAC parts.
