MetallicaJunkie,

You write: where do you get those tires?

We could buy these tires (wheels) in the Netherlands but that could be a VERY long time ago.
Dimensions are 73 mm 2 13/16 on it (see picture) but there is no brandname.

Reason I did show the picture was, he did write:

the one i flew not that many years ago would do 170mph with a 60 heli engine. 200 isnt that much faster
"Would"? Does that mean he didn’t measure it.

I often measure and log the real airspeed and for that I know my highest speed ever was 245 km/h (152 mph) in a vertical down line, horizontal speed 195 km/h (122 mph), pumped Webra Speed 10 ccm with Sonex pipe and own design pattern airplane. That's why I think 200 mph you will not reach with that plane, but I am curious.
