I really like the idea of using screws that are threaded through the plastic firewall mount from behind to replace the four mounting screws at the outside of the firewall. With the nuts to the outside, it means easy removal of the motor and not having to loosen that cheezy firewall and replace it if not broken at the supports. Unfortunately, I didn't find any info or pic of that mod until after my very first crash that cracked the original firewall beyond use. Once the new firewall is glued back into place it is difficult to remove it, due to the hot glue or other glue sticking to the foam. Obviously the foam will continue to tear off in each additional attempt to remove that plastic mount plate for any future repairs. Just seems that the method with the screws and nuts would make it all easier on the newbie for repairs.
Any rate, in replacing the shaft at the gearbox, I didn't find a lot of answers as to how the two different gear bearings went into the gearbox at the time. I have no clue as to what I did being right or not, but once the motor is hooked at the firewall with the stock method, it is indeed hard to have the light bulb come on and realize that you may have made and error and are in need of correcting it at some point. Well, I progressed past that and the motor turns with no notable extra noise or binding on the shaft. No smoke and no extra drain on power that I have noticed, so I am not inclined to tear into the gear box just to see if I did something wrong at this point.
That said, I have my new gear shaft in place and the replacement firewall mount holding it solidly there. I am a bit concerned about the proper angle of the shaft and the possibility that I bent something, not to the shaft, but in the firewall foam crushing a bit with the sudden and solid impact of the crash. I was looking at before and after pics, but the angle of a camera can often make things look better or worse and not necessarily show the real meat and potatoes of what it all looks like in person. I'll attach some individual pics and please let me know if this seeming looks okay or not as to the angle of the prop and shaft. The original shaft was bent and I replaced it, as shown on the after photos. I really don't want to dive into tearing off the new firewall plastic mount in order to remove and replace anything, if possible. I shot the after photos with the prop actually moving at the time as it sat on my official ironing board SC work bench. :-)
