Prop modification

Hello All

Can anybody tell me how this prop modification might affect the performance of this T-200?

Unfortunatly my pool is being redone so the test tank is empty.




Woah! Very interesting modification. I honestly couldn’t say how this will work but here are a few things I’m thinking:

  1. This will definitely draw more power since there is more resistance on the motor. I’m not sure how much more thrust will be generated.

  2. There will probably be a vortex generated behind the second propeller since there isn’t a smooth tailcone to guide the flow. That will reduce thrust somewhat. We see this effect on a thruster with the tailcone removed.

  3. Without the support of the rotor body, the back prop might flex a bit but I’m not sure how much.

I’m very curious how your test goes. Let us know!
