I've used tip to tip fiberglass on a couple rockets and thought it helped the durability and longevity of the rocket.
I recently read a comment that tip to tip isn't worth it because those that use it don't understand the stress points involved.
Is there a consensus on tip to tip glassing? Does it really help make the fins stronger and more resistant to fin flutter and hard landings? Or is it just adding weight without adding any strength that you don't get with good fillets? Is it only worth it on MD rockets? Is it overkill on TTW mounted fins?
I did tip to tip on one of my rockets. I used three layers, the first small, second larger, and last over the full fin. I thought it added strength and a little air foil to the fin because I thought I remembered that fin flutter started at higher speeds on fins that didn't have a uniform cross section.
The black lines are the outlines of each layer. I use a sharpie to mark the glass cloth when I cut it out.
Of course none of this helped when I catoed an EX motor and blew the whole fin can off the rocket. I only found two fins with all the glass peeled off. There was still some of the tip to tip glass stuck to the BT parts I found.
