Aerowoof is correct, (at least that was the most popular but I think there is a smaller version also)

The Bud Nosen A&A industries "Gere Sport" Bipe was a big docile flyer with the proper set up, Balance(s), control throws and incidence between wings and Hor-Stab.
There is a thread or two on RCUniverse regarding the Gere Sport and I think you could find more doing a Yahoo search, here is a pic from an RCU member I got plans from awhile back but sense sold

An after thought though, You are saying 10' span?? Nosen was 8' / 96" and I do not remember if Ikon NWest offered a Gere or Flair.
