Turnfin mounting and location 67 rigger

[Samuel Hagan JR]

I have no clue what's right or wrong on mounting a turn fin in on a trigger. Does it look okay?



Also do you guys use 1/4" shafts that are stepped down?

What size hardware is good for a 67 digger.

And a good starter prop.

Trailing edge 3/4 to 7/8 ahead of the cg works for me

Anybody on the questions?

Best to use full 1/4" unless you will have a lower power set up and need smaller props.

Most engines will pull a stock ABC H-32 and they have a 1/4" bore.

Normally the T. fin T.E. just ahead of the CG works.
