Just tonight,i emailed my local hobby shop and ordered a set of muffler screws for my OS 32sx,one of which I had stripped out and a set of mufflers for my Saitop 90 twin that will be flying soon.I bought both of these engines from sellers on ebay.The shop is about 25 miles from where I live and it would probally have been better to get the two things i wanted sent to my door.But in the long run,it's nice to be able to go that 25 miles,get my screws and mufflers,pick up a few gallons of fuel and whatever else i need at the time and go fly.I buy my radios from him as he is competitive with mail order.Three this last year.I won't buy most of my stuff from him but it is great to know that he is there,and like some rock group said a while back"long may you run"
