I would suggest a good engine...OS is good, and you might want to check an ERVINE ....This will give you the edge to grow with you durable engine...As far as radio...I would say buy all the Radio you can afford, regardless of the brand......A radio is like a putter (if you play golf)...Get one you can live with...Mulitple model radios is a Godsend.....less hassle...Try to get a brand that most of your club members use..(and on a different freq).they can advise you about programing and the like...
Good Luck...
