Curare can be built from MAN plans. Dynamic Balsa sells cores for both wing and stab. This is not a tough build. I have built about a dozen for myself and friends over the last 5 or 6 years. A lot can be done to lighten the plane without giving up structural integrity. My heaviest (painted fuse) weighed 8 lbs 4 ozs with an OS 91 pumper in the nose. I t flies fine and is rock steady in heavy wind. It is my current backup. My new one (12 flights now) weighs 6 lbs 12 ozs. I've learned a couple things about weight reduction. The new plane is unbelieveable. It's almost too easy to fly. As soon as I quit helping it, scores should go up significantly.

Atlas is also a very good air plane. Duane's Altair is HUGE and very smooth. I may build one this winter just because. Compensator is a good plane. Daddy Rabbit has been dominant for a number of years. All these planes are basically box fueslages with foam wings and tails. There is nothing difficult about building these great planes. Build them straight and align them correctly and the fly great.

A couple of mods need to be made when converting from 2 cycle to 4 cycle. SPA is not terribly picky about minor mods. As long as a plane looks like what the builder says it is, it will be accepted.
