well I am running around 2100 if I hold the helicopter and measure, I will need to find a way to strap the tacho to get a proper in the hover reading and you are right it is sluggish but controllable

none of my buddies will get anywhere near me in the hover :-) I would not try the same trick with a 30 powered bird

I've seen models that were strapped down to a table go into some significant harmonics with "not good" results! :-o
You may be getting away with it with a 450 size bird but I have to agree with Kevin on this one, you're asking for it! ;-)
As for the tach, the versions that Miniature Aircraft sells work very well and you don't need to be that close to the model to use them. The only downside is, they're not cheap, but they are very good!

Believe it or not, yes you can. If the model has a half way decent setup, and the rpms aren't shifting all over the place, you should be able to get a pretty close reading. We've done it many times!

I have seen some flying were I cant even keep up with the naked eye, let alone look through a view finder

Yeah, well, I was referring to the kind of 3D flying us "mortal" types are likely to do! :-) I've successfully tached a friend of mine through kaos', tick-tocks, stationary flips, and other such nonsense. It was no big deal. As for the guys you're referring to? I just watch the show from a "descreet" distance! ;-)

I know that sort of flying takes skill, but pretty its not IMHO it just looks totally out of control , I like the more graceful moves -- Kevin R Reply address works
