That guy who started the VSCs last century may be at it again...
He mentioned something about a "fun scale" gathering a while back, and has now put some basic details together for trying it.
Full details are in the Events calendar for October 2007 and forum. (I hope)
What it is, is multi-engine, profile, 1/2A Scale. 'Metric' 1/2As allowed (0.06s).
Simplified flight requirement: min of 10 laps with both (or all) running.
Just a fun thing, not to go for blood and glory. 'Nuff challenge as is.
