>Many European moulded models are available with either style of tail. Yes, but the effective tail sizes between the two version are always very different. From a recent RCGroups post:
>> During a stall with the v-tail they like to do the snap spiral. >> Its quick and you have to be careful. > I think you've been flying too many V-tailed Euro-moldies. :-) > All the ones that I've looked at typically have badly > undersized V-tails, although the X-tail version of the same glider > typically has an OK tail size. For example, here are the horizontal > and vertical tail volumes I calculate for the Europhia from > the 3-views at www.aerodesign.de : > > V-tail version: > Vh = 0.36 > Vv = 0.0115 (yikes! that's real small, and likely to be snap-prone) > > X-tail version: > Vh = 0.41 > Vv = 0.0205 (barely OK) > > The effective vertical tail size on the V-tail version is roughly HALF > that on the X-tail version, which isn't all that big to begin with. > Go figure. > > In reality, there shouldn't be much of a difference in > aerodynamic behavior or in weight between different tail types, > provided each one is sized appropriately.
