Scale Aircraft Conversions has produced replacement gear for the Hawk/Testors OV-10 Bronco kit. I have reviewed several of these sets, and have purchased a few more on my own, because in all cases they have been superior to the kit items.
The white metal replacements are a clean drop-in for the kits plastic parts. The supplied items include two main gear struts and braces and one nose gear strut. Also included are weighted tires mastered by Doug Smith of Royal Resin. The weighted wheels are a significant improvement in detail over the balloonish kit tires. The SAC tires also have tread and improved rim/lug detailing.
A side-by-side evaluation (see photos) indicates an identical strut replacement that should provide greater strength with a significantly improved weight capacity and abuse tolerance. In some cases, painting may not be necessary.
Highly recommended.
