I am interested in building the RD-1, by Bob Hunt. Does anyone have any information or experience with this airplane?? I'm under the impression that this plane is designed with a foam wing. Since my building skills are limited to built-up balsa construction, I was wondering if anyone has used a built-up wing for this airplane?

Also,... I seem to recall someone telling me that the RD-1 uses the same wing as the Sig Twister? I don't know if this is a figment of my imagination or if this is really true.

Can anyone verify or accurately dispute these theories of mine??

Any information would be appreciated, thanks!!
