Testing propellers on a 25cc weedeater engine! (RC prop car build Pt.1)

- In this video, I make an adapter to fit the flywheel of this weedeater engine so I can bolt on propellers and test them out. I tested two propellers and got some pretty good results. I'm quite pleased that my sketchy looking test rig worked.
If few notes:
The lawnmower deck with this engine was about 30 lb. Which is quite impressive that the little weedeater engine was able to push it as well as it did.
If you're wondering why I chose to go with a 3 bladed propeller instead of a 2 blade, this is intentional. With a 3 bladed propeller, you can get the same amount of thrust with a smaller diameter, which means the engine, could be a little bit closer to the ground, allowing the balance of the RC car to be lower, and therefore handle better. Also, I can make the frame smaller which means it'll be lighter as a result.
I was doing some further testing with this after the making of this video, and the nut that holds the propeller on came loose, even though I just tightened it. So I replace the nut with a nyloc nut.
Gr8 test young man! Cant wait till you start flying yourself around the yard!!! Lol
Love the Prayer!1😇🙏👍
You should of stood on it 😂😅
I actually did sit on the thing after the video was uploaded and to my amazement it managed to move me across the floor although slowly at first by the end of the shop it picked up a little bit of speed.
This is the kind of stuff i live for lol.
cut off the cooling fins from the flywheel, they just make un nessesary drag and the coolin from the prop will be more then enough, maybe even cut off some of the cooling fins from the cylinder for waight reduction becuse of the better cooling from the large prop
The flywheel fins are not necessary, but the fins on the cylinder help conduct heat away by adding more surface area. The only thing with breaking fins off the flywheel is, you could end up making the flywheel unbalanced.
