Anthony,
I'm probably not the best person to answer that specifically (I wasn't
involved in the airframe construction), but I know the weight of the tail
section got away from us for the construction (considerably). More structure
than anticipated, more resin etc. I think the 2 other bits came in close to
expectations in terms of weight. I'll ask Karl.
Great motor BTW. The Cesaroni O25000 provided some awesome lift off photos -
a plume to complement the rocket :)
Cheers,
Troy
