Hi, i'm a beginner with q-500 (424) in venezuela south america, have a viper and whant to built a new fuselage, i know that some fuselage have better desing than others, and also you can make some legal mods to it, changing the v tail degree and incidence, and the distance between engine backplate and wing leading edge, which is the best fuse and configuration or modifications you can make to it, thanks.

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.

Thanks for your help, yes i know Gabriel Tahan, but he lives in Caracas (8 hours away) and i don't have his phone num. or e-mail addres, yes i whant to built from scratch but i heard of using the viper wing with some other fuse that fly much better maybe people making noise!!!, but by now i'm using a Viper and i whant to built another q-500 from scratch as a second plane and i whant to built as it has to be. skined hinges, internal linkage and all the improvements, reinforce the fuse (tricks)

HOLA RUBEN¡¡¡ TRY SMASHER WOOD FUSE FROM DON STEGAL. VERY NICE AND VERY FAST.
SALUDOS.

There are a couple sets of plans on www.supertrc.com if you want to get some ideas for your own design.

Both good flyers.

Mr Matney,

I was checking out your wood/foam/glass "Dawg Goneit". That is a hell of a deal for $100! You must be doing this either for free or the love of pylon racing. I think I will put one or two of those on the christmas list.
