Ed,
It's an OS .61 2 stroke, I got new about 3-4 years ago. Don't
remember the model. The LHS did a pretty good turnover of stock, so I
suspect it was a current model. It would drag my 60 size trainer
vertical with an 11x6 prop, so it seemed to be a pretty strong motor.
And I do have 3000 x 75 feet to get it into the air if needed.
