To my knowledge there is no kit of the S-2C out there.I have the Kyosho S-2C ARF.It is 48"span and I have an OS .52 on it and it flys great.Bob Dively Models has an S-2S in an 80"span and is a kit.Hirobo had a 68"ARF and discontinued it.The Midwest Super Stinker might be the only one close and I think it is discontinued also.There is one for sale in the market place that looks nice.Hope this helps.
