Help! Tiny Trainer doesn't fly

[Mr Man]

I switched the motor rotational and it worked... finally! So happy to get ny first sicsessful flight. Only problem I've had is that since the motor is spinning in the adverse direction it was designed the spinner nut unscrews itself sometimes. I've found that when the props have an R on them, like "6045R" it means they are reverse props. Now this is where it gets confusing. The prop spin direction is relative to the front of it, unlike the motor spin direction. I think this is because for multirotors you look at the prop from the top down. So, a "standard prop" is actually considered to be spinning CCW.

Correct

I’m with you! I’m used to sitting in the cockpit watching propeller ticking over clockwise and I don’t think of that is being a counterclockwise prop. Glad you got a good flight in!

Torque that thing down.

Replacing the stock prop nut with a nylon lock-nut can help prevent the unscrewing. Whenever you use up the 6045R props you can switch the motor again and use regular 6045 props so the unscrewing won't be an issue anymore.

...the spinner nut unscrews itself sometimes...

I agree with Tench & Mr Man. A nylon nut will prevent the prop coming lose. But a pliers & a little extra umph will also work in planes.

These will not work so well in a quad. In quads, you should have the correct threads. In planes our motor speed is relativity unchanged. In quads the motor is changing speeds many hundreds of times per second to maintain stability. This constant changing of speeds is what loosens the prop.
