mount reversal

[drummaker]

I have purchased this
http://www.hobbyking.com/hobbyking/s...dProduct=34108
motor for A t6 Texan Kit I am putting together. I realize now I should not buy a motor till I actually get the kit unless I am buying exactly what is recommended.

I now know that this motor needs to mount inside the mount with the shaft extending through.

I have read a bunch of posts all over the internet about reversing a motor since every outrunner I have seen mounts on the Back of the motor.

2 Questions
Are there outrunners which already are set up that way? and If so how would I know tht

and

I believe that since I am trying to have the shaft come out the back so to speak that I can just loosen the allen bolt, and press the shaft till it extends out the other side then re tighten the bolt.

I am thinking I can make s flat spot on the shaft where it will be lined up with the allen bolt. I can then just take the C clip off the now propeller end. I think I can do this because there is no longer a need to hold the shaft from that end because the motor now wants to pull itself together with Prop thrust instead of appart

Is this correct?
