Re: Duration
With this year's rule changes, especially since the minimum helicopter mass has been lowered and there is no maximum rubber mass, I think we might be seeing longer flight times (>2 min) more commonly.

I am pretty surprised about the no maximum rubber mass. that seems, odd. although rotor diameter i guess still limits you.What has the minimum copter weight been lowered to?

Not an enormous difference, but a difference nonetheless: maximum rotor diameter is 35 cm, minimum mass w/o motors is 3.5 grams.

In AMA events we regularly make helicopters that weigh less than 0.5 g and are larger than SO helicopters. It is all about wood selection, size and specialized construction techniques.Lily Essence wrote:We'd end up turning out the smallest helicopters eva!illusionist wrote:3.5 GRAMS?!??
