Horrace, good to hear from you and I certainly could not agree more that there is more to modeling than just "3D and backyard electric ARF".

In the distant past I too have had some involvement with 'controline speed' and am well aware of some of the witchs brew which were used. As a matter of fact I still have my 1956 OS type 11 pulse jet and am currently building a replica of a 1949 Hell Razor nats winner only this time around for 'D' class just for the heck off it.

However there is no history lesson in those first two posts nor is there any relationship with any kind of modeling. And I will maintain that I find the Subject and the tone of the posts most particularly inappropriate in a beginners forum.
