Help! What prop and spinner

[Coopers87]

Hi guys finally about to put my ft spitfire for its maiden outage, just need to know what 3 blade prop and spinner you recommend for my racestar b

I know you mentioned the motor is a Racerstar but if you can provide the specs it makes it less of a guessing game; another factor will be the ESC size. You said B so I'm guess its around a 2212 however the KV they make a few different KV of that motor.

Sorry for some reason most of the message didn’t come out, it’s a race star br2212 1400kv motor and a 30a esc if that helps sorry for the misleading first post 👍

I've used that exact motor on my Scout with a 9x4. If it were me and I wanted a 3 blade I would use something like this https://www.masterairscrew.com/collections/3-blade/products/3-blade-7x4-propeller. Keep in mind you need to go to a smaller diameter when switching to a 3 blade. This will also probably not be as efficient but will look the part on the Spitfire.

Thanks for the help, it’s definatly more for aesthetics than anything else. Will have a look

I suppose the next silly question is which rotation do I need it cw or ccw

 

[quorneng]

For scale then CCW (viewed from the front) unless is was a Griffon powered version then its CW
Otherwise its more about which way you will have to counter the 'swing' on take off.
If its hand launched then its which way you need to be ready to correct for the torque induced wing drop until it has picked up speed.
