Schweet!! Having said that though, believe me, when I finish my 34%er with 2 rx and 3 batts and the whole 9 nine yards I will probably------------still not use the SF switch. Just kidding!! Or am I, ok I will.
Andy,
I think RCATS also has some kind of optical kill
The whole idea is you want to be able to kill the engine that is not related to anything that has a linkage to it. There is even a setup on Towers site that uses a micro switch and a servo but it pprobably weighs something like 3 or 4 ounces. The weight and simplicity of the optical switches are why we use them.
