Francherized" Twister#0 source

I am interested in modifying the SIG Twister I've just started building. I have heard of the "Francher" Twister but I'm not sure what changes this involves. Any ideas or help out there?
Thanks,
Phil

THere are several small but significant changes/additions/techniques included in the Fancherized version. THe stock twister is a very good basic profile. Ted's experiments were to make it fly more like a modern long-moment stunter.

THe big difference is that the fuselage is stretched by 2-3 inches.

If you email me your info, I'll send you the articles that Ted wrote.

Also note that Leonard Neumann of Stuka Stunt Works sells the "Fancher Authorized" revised plan set for the Twister with all of the changes incorporated.

Check with Bob Kruger. He not only transcribed Ted's article, he updated the CAD drawing for it, and has a very nice version of it..

VERY nice,Phil. Did you 'triple' the inboard nose section? Where will it's CG be? How much tip weight? Are you usng any spruce spars?

Hi Phil,
Thanks.
I sort of quadrupled the nose...2mm ply/93g cf bi- directional/Manuka/93g cf bi/2mm ply. Bonded with Epiglass Hi-Tech 9000.
I have a small supply of very fancy carbon cloth, I use it to make leading edge sections (taco shells)for my competition free flight power models. Very expensive. but amazing stiffness.
I'll try the CG well forward as Ted described and experiment. I'll put a weight box in and hope that empty, it's not too heavy. The fin is aerofoiled and it has adjustable leadouts. I also made my own undercarriage out of carbon....
I have models which are probably better for F2b than a Twister. (no disrespect to the designer intended) This model is to be used as a simple test bed for getting into 4 strokes and because it seems everyone should build a Twister once in their lives.........

The spars are from VERY stringy balsa, webed in the centre

Good luck with yours
