GG,
I have the p-38 almost done. I went with the Vario 3 blade variable pitch blades/prop adaptor from
www.eam.net I can not seem to find a 1 3/4 inch spinner for my 51 in p-38. I know that I would first need to figure out the best pitch and then cut the grooves for the spinner to fit the blades, but I can even find a 3 blade spinner. It looks like you are using a 3 blade system with a spinner. What are you using. Using the Himax 1220 with 30 amp esc and 3 cell 2100 15c in parallel. 45.6 amps at 460 watts 65 oz thrust and 60 MPH with hs 65 servos. Should really go.
