RE: Fuse???
Hello,
Do you know Gabrial Tahhan? He is an excellent pylon pilot who also lives in Venezuela. If you want to learn from someone local... I believe he is the man in your area - a really good guy who loves to race (excellent pilot who is very fast). Are you planning on building a 424 fuse from scratch? If so, the Viper is not a bad starting point as the configuration works very well and the moments of the nose to leading edge of wing to elevator hinge line are very good. What needs to be improved on the viper fuse is the strength of the nose and tail and landing gear block - there are many threads documenting these fixes. Another area for improvement is making the elevator/rudder linkage internal instead of exposed. Do not change the V-Tail angle. To get the Viper to really fly well, the Vtail incidence should be 0 to the fuse and motor. The wing needs just a touch of positive incidence (leading edge higher than training edge) to fly with no elevator trim assuming the center of balance is about 2 7/8" to 3".
If you really want to see how to put togther a wood self built quickie, buy one of the quality 424 kits (non-composite) like the Seeker, Hurrikane or Vortex (there are also others that are very good). Good luck.
