As far as 4-strokes go, don't believe any of the hype about their maintainance. I have mostly 4-strokes, and they ae no more difficult to run or maintain that a 2-stroke. And you DON'T need a tach to get them to run right.
Thanks Minn,
I am actually in the process (have been for several months) of building a CG Super Chipmunk. I have all
intentions of using a four stroke with this plane. After reading some of the above posts I was starting to doubt that decision. All I need is to fork out more dough for equipment to use the four stroke (such as a tach).
I have been trying to do some research on four strokes to make an intelligent choice as to what engine to use for this plane. Several people have told me an OS 90.
I want a good quality engine that will move the plane around with authority. It doesn't have to be the fastest, or have outrageous thrust, but it must be dependable and last for a while. What is the CHEAPEST engine to fit this criteria? It would be nice to stay around the $200 range, but I realize that probably isn't going to happen.
What would you recommend for this?
Thanks,
Wings
