I first encountered the Sig Kavalier over 30 years ago. I thought it was a great kit with a great wing. So when I decided to get back into the hobby I was at first disappointed that I could not find the kit listed by Tower, but delighted when I found it to be available directly from Sig. I have a kit now and will be building it this winter. Sig says,
An Intermediate Level R/C Sport Model
The heart of this beautiful airplane is it’s superior wing design! The light, strong, built-up balsa structure incorporates built-in wingtip washout for superior stability and control. Even expert pattern fliers are impressed with the KAVALIER’s smooth, responsive flying ability. Make perfectly coordinated, in-the-groove turns. Fly through any aerobatic maneuver with rock solid precision. Flare out for slow, main gear only landings with no tendency to stall or snap roll. Highly recommended as a student pilot’s second model!
