>I notice though that v-tails don't roll as well as my standard tail >gliders - not a true axial roll. Any comments? If the nose of your glider is dropping when you initiate a turn, then the v-tail does not have the correct differential to be neutral in pitch. This would result in the small barrel rolls I believe you are experiencing. For more information on v-tails, such as sizing and tuning, I recommend a visit to http://www.bright.net/~djwerks, where you should look into the Ask Joe and Don section. Everything you want to know about v-tails is there. /amC RCSE-List facilities provided by Model Airplane News. Send "subscribe" and "unsubscribe" requests to [EMAIL PROTECTED]
