Thanks for the info re retracts.
I have checked out the You Tube Vid and will have a look at them when they release in June.
So after postulating over various motors, I am still contemplating the YS 1.20 FZ . I have a guy who has a brand new ( never Run) 10 year old motor with a tuned pipe.

Are there any issues that I need to look at with such an old motor.

Would there be any parts that would need to be replaced before firing it up?
Also how much bench time does it need before I can out in it the plane to fly?

Almost ready to start building

Cheers Greg
