The times appear to vary quite a bit depending on the model ordered. I've heard of people ordering in September and just now getting it, some getting it in a couple months after ordering. I understand that they will run a particular model, and build every one on order at one time. Then they switch to another model. We ordered a 274CKDS Eagle HT on December 1st, 2020, and it arrived on March 15th. It may also depend on materials on hand too. If they are short particular items the models using those items may be put off until they have an idea of when the parts will be in.
