I built the 60 as a kit. The drawbacks were the foam core wings which are heavy and a pain to build(my view). The plastic engine cowl is total junk as it has to be cut up so much it falls apart very soon. The wing saddle is very weak if not worked over also.
The good thing is that it flys well on a 61 2 stroke or 91fs which I had on mine. Think I would try an ARF the next time.
