Does anyone know if you can reverse the prop shaft on an AXI motor? Meaning loosen the set screw and push the shaft through to reverse the mounting (like for radial mounting). I did it with my E-flite motor, but the set screw on the AXI motor seems IMPOSSIBLE to get out!!! Are the threads for the set screw REVERSED?? Please help!!

Thanks
Diego

Make life easy and buy the fire wall adaptors made for the AXI. Beside making it easy it also makes for no worrys about the collet prop adapter coming loose on the motor shaft. Because it eleminates the collet adapter.
Try Hobby Lobby

Lazyflier You are right of course - the fire wall adapter is the best solution. However my AXI 2208/16 is not "firewall adapter ready" - must be one of those earlier models from AXI that I picked up from Hobby Lobby. So I am stuck with mounting it behind the firewall. I was therefore intrigued by Diego's question - if there is a way out then the existing screw holes can be used to mount it on the firewall from the outside and put a prop adapter on the extended shaft - it would be neat radial mounting change on my AXI - Thanks diego you got me thinking

Does anyone have a better solution?

Saw this configuration on a HiMax site. Maybe it would work for you?

Hmmm... Those set screws are probably Loctited and torqued right down in there... They don't want that shaft to slip out after all.

The problem is, once you get the shaft turned around, what holds the motor together? With the pull of a prop, the shaft will slip right out of the bearings without something to hold it together.

Thanks lazyflier - very neat interesting contraption from Himax.........


And Matt - it did occur to me after my post that the shaft can slip out and the motor would come apart - perhaps a wheel collar on the shaft with a fiber washer sandwiched betwen the collar and the ball bearing will be adequate to hold the motor together

But I guess the cake goes to the idea put forth so lucidly by SAL C with photos and all - Thanks Doug for letting me know - am definetely going to give it a shot

There is a "C" clip holding the shaft from pulling out if you take the collar off.

I only used the have used the firewall mounting method once, on my Jr. Falcon. I just made the center hole in the mounting plate large enough to clear the collar, and it mounted just like the brushed motor it replaced. The Collar was about the same thickness as the motor mount plate so it worked fine.
