Hello, In my experience both types work equally well.
Theoretically a V-tail is more efficient than a cross tail, but less efficient than a T-tail. In practice I can't pick the difference. A V-tail can be lighter than a cross tail, and much lighter than a T-tail. Even this does not matter much. The best handling model I have ever had has a V-tail, but I doubt if it would be better or worse with a well designed cross tail. The only handling problem I have ever had with a V-tail model was caused because I did not set it up correctly. I set this model up with insufficient rudder deflection, and did not have enough rudder authority to recover from a dangerous situation. After some repairs, and with the set up done properly, it performed beautifully, and still does some years later. When acting as elevators the ruddervators need very little movement but, when acting as rudders they need as much as you can get. My problem could just as easily have happened with a cross tail model. I am quite happy with either tail type, though I rather like the look of a V-tail. Many European moulded models are available with either style of tail. When next I buy one my choice of tail type will most likely depend on what the importer has in stock. ***************************************************** Ian Roach Kiama, NSW Australia [EMAIL PROTECTED] Phone: 61 2 4232 1775 ***************************************************** -----Original Message----- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] Sent: Thursday, 8 September 2005 10:42 AM To: rc Soaring Exchange Subject: [RCSE] Thermal duration V or + tail I've noticed that the Europeans seem to prefer the V tails but the Americans seem to prefer the plus tails for thermal duration.
