Sorry, I disagree.

I tried Air retracts back in the 70's and hated them for various reasons. I became a "Mechanical Only" guy.

I am now reviewing the Top Flite Cessna 310 which came with Robart Air retracts. I will admit that air retracts have come a long way, and the Robarts are excellent units, But I can't tell you how many times I wished they were mechanicals.

My advise: Use 2 Y cords and don't even THINK about Pnumatics.
