Yes, it will fit. It is meant for a 3mm motor shaft, and the motor you want to use has a 3mm shaft. The 3-blade prop will also fit, IF it is not a straight fit, you can easily drill the prop hub to enlarge the mounting hole and fit it.
Well, if you have to mount one of the bigger props - TGS 9x6, MA 9x6, 9x5, 10x6, etc., it does provide a good grip on them, and the shaft fits perfectly, you wouldn't even need the adapter rings. I am using it on my Mini F4U Corsair and am really happy with the results - after I replaced the original motor, this prop adapter is what kept the balance of the plane in the same spot since the new motor was a bit lighter. :)
Prop shaft length is 23mm, so you can use very thick props. The thinnest prop you could use is with a 6mm thick root. These adapters are tightened to the motor shaft by only one set screw instead of 2. So grinding a flat on the motor shaft is a good idea.
Aw ****, turns out the measurements I gave is for PRODUCT ID: PA-3MM-5MM-C which has a 23mm long shaft for props, just one set screw and actual weight 9.3g.
This prop adapter here with PRODUCT ID: GS0154M and 8722 on the bag is short one with 16mm long prop shaft, held to the motor shaft with 2 set screws and actual weight is 6.3g. So, all-in-all this prop adapter is lighter and held to the shaft better. The only reason to get PA-3MM-5MM-C is if you have a really thick prop core.
Still, the nicest M5x3 prop adapters are attached to quad motors NX-4005-650 and NX-4006-530 that I have. They weigh just 4g, attached with 2 set screws, 14 mm prop shaft length. I really wish HK would start stocking them separately!
Yes. This will mount on a 3mm shaft and will fit inside a 5mm prop hole. If the prop doesn't have adapters, then it can be easily drilled. I have one of these and I haven't had any problems, but you might want to get a colet style. These use two grub screws. colet style: product id PA-3MM-5MM-B
If this helped you out, please credit me.
If you have a 3mm motor shaft, and a 5mm prop hole ... it should work. Personally, I would suggest collet type instead of grub screw though, they seam to hold on better. Prop hole size you can probably modify easy enough* but motor shaft size has to match.
