Speed master strut install ?

[Andris Golts]

Hi all just recieved my speed master strut .Am i correct in assuming that a 1/4'' brass stuffing tube go's through the strut body to with in a 1/8'' from the rear of the strut then insert the speed master bushing ? There was no instruction sheet included . Regards Andris Golts.

I find that by running the stuffing tube through the strut, it takes away the ability to change the angle of the strut.
I usually insert a length of tube that stops about 1/4" from the front of the strut, & cut the stuffing tube long enough to enter the strut & butt up against it. This allows the strut angle to be adjusted in either direction as long as the floating bush doesn't cross the join of the two tubes. That all depends on the length of the strut. Some are shorter than others.

The larger (.250) struts are typically used in gas/nitro applications where the flex is square-end "floating design" and thrust is taken at the strut. For FE we mod for thrust at the motor collet.

Like this : (as stated above, the bushing was henceforth shortened after picture was taken)

*One must be very careful if solid portion of propshaft extends far into stuffing tube and can bind when angling strut either up or down. In this picture the flex DOES have an extra long propshaft as it is a stepped-down .250 so angling (if indeed necessary) must be done carefully.

Good point on the solid portion of the propshaft Tony.
I did have that problem once but changed the shaft to one with a shorter stub. I had to shorten the bushing too if a recall. It was on a chinese RTR setup conversion of some sort with a very short strut.
