Recently finished my RST ( Rugged Stunt Trainer),  I am very pleased with the kit & the first flights.  It flies as well as anything that I have built or flown. I have it trimmed to my liking & enjoy every flight.  I was surprised how well it handled a breezy & gusty flying session. It took me 4 months of stop & go building & personalizing to finish it.  I do think it could be built in a week of evenings.  I am using an OS 25FP & .012 lines.  It will be my plane to learn the beginner pattern.  It feels that it will be easy to progress on to the full pattern with the RST.  Great beginner's plane, club trainer, sport flyer, & practice plane all on 2 ounces of fuel.  The hard wood fuselage & foam wing allows it to take a beating & keep on flying.
