So...a dead baby harp seal is no longer a baby harp seal, but just good eatin'?
1500 grams is 53 ounces. Will fly fine at that weight, if you can get it lighter, so much the better. Not easy...tailerons rather than ailerons helps a bit.

I'm glad to hear Motors and Rotors is carrying this, I want to do the review thing, but unless people are able to get access to the kit, it's no good. I got mine direct from the factory through some connections. Ordering from Japanese hobby stores(I think they have it?) is a pain for most people. It would be perfect for the Lambert. If you can find one of the out-of-production A-7s, that would be even nicer. They have an A-4 under development, don't know where that stands...what will the pricing be on the Ducty?
