Hey All..... I'm rebuilding a nose damaged Hobbico Superstar OS 40 LA for a neighbor and since it was a RTF I do not have the specs on Downthrust or right thrust, since the firewall was removed by the landing gear in the crash ( common I know) I have replaced it with a new fabricated one, repaired the top front and bottom front of the fuse, now I am wondering about down thrust and right thrust, my usual rule of thumb is 1/2 inch difference from prop tips to wall measurement for right thrust..... however does it need down thrust???? Waddya think???????
Thanks....... Captain Crash...
