Default RE: Build Thread-Scratch built for 8s

Hi Dave,
If you are talking a 4130/20 ..... then something in the 18x12 area would be what you need. Alternately, an APC 3 blade 15.75x13 pattern prop will get you a bit more clearance .... but is not as efficient.
IMHO .... stay away from CF gear, either self made or purchased. Either it delaminates or is too stiff and launches you back into the air on a less than perfect landing. Just go to TNT and they will make a custom aluminum gear for you. I did this for my Inspire 90 and have been using that gear for 2 years now without an issue.
