The Show Time LG is perfect for the Do,at least for harrier landings,about an extra 1.5 " height and it does not flex so much like the stock gear. No more broken props & I can live with the extra width. After breaking the last of my Zinger 17X5 (cut down & tapered to 16.5X5)I found out how critical the perfect prop for 3-D can be. I had it on OS1.08,the spool up was perfect and the RPM range was at about half for hovering/T.R. When I put another prop on, the difference in a hover was dramatic. You want a prop that will spool up quickly but not pulling too much(not always climbing).With a little prop tweaking I can easily adjust in the vertical,just a click or 2 up or down on throttle does it,makes it so much easier when the throttle movement is minimal. Now, if the wind would only stop, I could practice tail touches while TR-or at least get a little lower.
