If you have flown a slingsby, thank God you survived, many haven't ...we were talking about trainers and where I come from this is fighting talk, fortunately I moved but the 400 a similar price to the 150 ? We will have to agree to disagree but flew with a "face" on Thursday and went for a jolly later .... in a 150! he was impressed with a stall turn and all perfectly legal ... 150s are great!!
