    I guess nobody runs the small riggers any more.

    I have a nitro outboard cat that I decided not to convert. No prop was included in the deal for it. So have no idea what to run. 42mm is the largest prop that will fit. Would this work? If so would be great! Then i would have no excuse to not get some fuel and a battery for the glow plug.

    These are 40mm so they would fit.
    I know nothing about Nitro Cat's , so I do not know what the 1.7 pitch will do for you besides more speed.

    I do know that these props have some lift in them.

    They are yours if you want them.

    If so Send me a PM with your full shipping address.

    Big difference in props between nitro and FE... not much info on nitro on this site, this is an FE forum.

    Thank you!!! Yes I am aware of that. I have several FEs (inc a 70mph 29" sprintcat. and have a lot of respect for 100mph club members) a Quickdraw powered Insane Cat and this outboard nitro cat I was planning to convert to FE outboard if I ever get around to machining the parts on my mill. Then thought a prop, fuel, and batt to lite the plug. Might as well see what happens. I have no experience with nitro. If they don't work well on nitro power band, It will make me get on making some parts.

    Thank You so much!
