SS V Tail vs Inverted V Tail
What are the advantages / disadvantages between the standard V Tail and the Inverted V Tail when applied to the Slow Stick???
thanks Jack |

* Inverted V has pro-verse roll instead of ad-verse roll, and so will turn better. Pitch control will be identical.
* Inverted V will hang lower than upright V, and so be more suceptible to landing damage. * It's harder to work out the control linkage on the inverted V, especially if it's mounted high to avoid the problem of hanging low. That's the main points- I can think of a few others but they get esoteric and of little importance very quickly. |

I think inverted V-tail is great for pushers with dual tailboon designs, where it advantages are:
Since I started with these designs I never broke a propeller again But in conventional models like SS this tail design break very easly. |

Actually there are two models. The red one was the first prototype and the second was the current one. The changes are only in weight and some fuselage and link optimizations. Both are built in 4 hours with depron sheets, EPS block and two fiberglass tubes from fishing sticks (???) (sorry, I don't know the english name for the 2,4m telescopic sticks used for fishing). This is my favorite model, fast enough to fly slope soaring or windy days, slow enough to fly in a park, stable enough to answer the cell phone while flying and has a turn radius of less then 4m. Wingspan is 120cm and weight is 550g-600g with a GWS EM400 motor, GWS 5x3 prop and a 200g Saft 1500mAh 9,6V Battery Pack. I can send building plans for these model, if you want. |

BTW, the word you're looking for is "Fishing Rod" (-: I have a pod-and-boom sailplane made from a fishing rod myself... |

Thanks for the "fishing rod". It is my favorite material for boons and wing spars, becausa it is strong, light and cheap.
This is another layout for inverted V. I call it Wplane or AMplane |

Thanks fella's, you gave me all the info I wanted..
alexcmag == how's about giving the details of your plane, looks interesting, would like to try building one... How did you make the wings, size agnle of tail etc. Jack |

The AeroSonde (first two pictures) is:
The construction plan is in http://planeta.terra.com.br/lazer/Ae...aaerosonde.gif. Since I has no CAD software, the plan was made with paintbrush, with a 1mm/pixel resolution. The Wplane (last picture) is:
The plans are in http://planeta.terra.com.br/lazer/Ae...antawplane.gif Both plans are in portuguese, but since the most of words are measurements and equipment specification, they are very easy to understand. I am a newbie both on RCgroups and on flight. I learned to fly alone, so both models are built to be very easy to fly, hard to break and keep the motor, propeller, engine, servo and electronics safe in crashs. I never broke a prop with these models, even after crashing a electric pole or the ground. |
