RE: Great Planes Super Sportster 60 Kit - First Timer
MrTooTall
I admire you for forging ahead in a complicated hobby without any local support!! I was out of the hobby (regrouping mentally) for close to a year after crashing on my sixth flight and I had local help!! Please find a club or someone experienced to help you check over the plane, tune the engine, set the radio etc.
For a used engine I would look to an O.S. Max brand in two stroke or Saito in 4 stroke in the RC Market place or over at the other forum: r c groups and concentrate on the seller's reputation first and the engine choice second when purchasing.
