I started a thread asking about the Guillow's large Hellcat and Cessna Skyhawk in the 1/2A forum. The general concensus was to build them for rubber band powered free flying or display only. Several complained about poor balsa quality and too weak of framing for using nitro engines and R/C gear, while others said not to put landing gear on the Hellcat, except for a display model. Needless to say, my two Guillow's kits will be hanging from the ceiling in the garage when they are finished.
