Hi.

Are You building from Model Airplane News (MAN) published Curare plan, MK Curare plan or...?
I have built one from MAN plan and I have a MK Curare 60 kit and plan. If I compare the two plansI think a MAN plan built Curare maybe could be built slightly lighter. It is for sure some extra strength in the construction so here and there I'm sure You can make it lighter. But basic construction is probably wise to follow. These planes really was ballistic things that was fast as lightning with a good .60 - .61 2-stroke with pipe. Select balsa wisely (light, medium, hard) and you can save some weight at least. The Curare I had back in 1970th was rather light,it was covered with Skyloft (available anymore?), clear doped and finally painted with 2 component polyuretanbased paint. Curare was the best plane I used back then. I have a short kit of Curare,based on MAN plan [Edit - MKplan], from Eureka Aircraft now that I will start buildning, over 30 years since last time I built a Curare. http://www.eurekaaircraft.com/plan_kits/curare.htm
