I was given an old Modeltech Cap21 ARC in the box, it has a 72" wing but calls for a .60 engine??? That seems pretty small for such a big plane. I have owned several 1.20 Caps, and know their flight performances pretty well, but they were Cap 231's and 232's. I've heard the 21's are proned to snap out at low airspeed. I am just wondering if this plane is worth putting together or not. It does seem like a good airframe for a OS 1.20ax or Saito 1.50 Thanks for any info.
