Not sure what the spec is on my Legacy springs for the main gear =
overcenter link, but they sat around for 5 years, then flew for ~200 =
cycles in the last six months (since first flight), and are quite =
robust, exerting at least 20lb force at the fully extended position.

Very little force is required to keep the main over-center links =

TK-5 shocks should have been adjusted to the same length as the donut =
