<p style="margin:0;padding:0;font-family: arial; font-size: 12pt; word-wrap: break-word;">> I thought you were using plywood? Recall my fins vibrated into shreds due to<br />> large size. Are you reinforcing plywood with carbon fiber or are the fins<br />> fiberglass? How many layers and are you doing anything special to reduce<br />> vibration?</p>

<p style="margin:0;padding:0;font-family: arial; font-size: 12pt; word-wrap: break-word;">Oh no Bloom.. this is my all fiberglass 5.5" Black Brant:</p>

<p style="margin:0;padding:0;font-family: arial; font-size: 12pt; word-wrap: break-word;">The fins are 3/16" G10.. so they're plenty tough. The problem is that the aft part of the fin is "floating" (not even physically rooted to the body tube):</p>

<p style="margin:0;padding:0;font-family: arial; font-size: 12pt; word-wrap: break-word;">On my L3 flight last spring, it landed a little hard and cracked those rear fillets (made with microballoons.. they were too brittle). So now I'm:</p>
<p style="margin:0;padding:0;font-family: arial; font-size: 12pt; word-wrap: break-word;">-switching to rocket poxy fillets</p>
<p style="margin:0;padding:0;font-family: arial; font-size: 12pt; word-wrap: break-word;">-then doing a two to three layer aft-fin tip-to-tip CF over the rocketpoxy</p>
<p style="margin:0;padding:0;font-family: arial; font-size: 12pt; word-wrap: break-word;">-then doing an internal fincan fillet CF layer (up to the inside of the BT that slides on over the fincan)</p>
