Now that's some good advise. I do it to my plans built planes but don't do it anymore for kits??
Hind site being perfect I wish I would have done it to my Mid West Hots I built this year. I have A lot of guys that would like me to build them one but I only made A copy of the wing ribs.
I try to never build or repair the same plane twice but it doesn't hurt to have the templates on hand just in case. Think I better start doing that again.
