I’m almost ready to do a water test. I plan to use the FR prop on my 65150 motor. I’m short on time, haven’t got around to designing my own fairing yet. Does anyone have one they are willing to share? Hope to have a smooth water flow from motor to prop during this test.
I could use the modified MaB one. But the file I have isn’t modifiable in fusion360, and it’s not for the FR prop, so doesn’t fit very well.
If someone already shared these, please point me in the correct direction.
Sure thing man. You have shared so much good info on your build that I would be happy to share whatever I can to help. Here is my entire Flipsky thruster assembly. Feel free to grab from it whatever you might find useful! If you are running a VESC or some other type of logger, I would love to know how this prop stacks up against the others. I tried my best to make an exact replica of the FR prop using dimensions i found on this forum and also dropping in different pictures i could find into the canvas and copying the profiles.
What kind of profile do your blades have?
Looks like uniform extrusion. Along the axis they should have an asymmetric (air)foil profile.
The FR definitely has an (air)foil profile, hence the different thickness of middle and sides.
For Fusion there is a NACA Airfoil Generator. By using this, you can first model the middle section of the blade and then sweep it a long a given path on the hub (to get the pitch) together with a guidance line (for the radial dimension variation).
Looks like you designed these for a thrust bearing. A thrust bearing would help the motor bearings last a bit longer. Can you provide a link to the bearings that fit this? You mentioned ceramic vs stainless bearing too?
I put a 45 degree bevel on the inside when designing it. Only had the reacher tech motor so had a bit of a guess for the Flipsky. Looks like it needed a deeper bevel to fit the Flipsky. That would of messed with the thread for the Reacher tech anyway so I wouldnt of allowed for it.
