Picking propellers for Explorer (Power Pack C)

[x43b]

My apologies, this is probably an obvious answer. I am not familiar with propellers. I am wanting to build a full size Explorer from the kit. The website says, "Both the B and C motor packs (c packs need 9x6 propeller)". But the only propeller options are 9x4.5 CCW and 8x4.5R. Power Pack C comes with a 10x4.5 CCW.

I assume 9x4.5 CCW is ok, is that correct? I figured I would just go for power pack C, after I learn to fly it, I wanted to add some more equipment.

Thanks for the guidance!

Bigger motor, bigger diameter prop, waaay more thrust. Sometimes more speed.

A "C" motor will spin a 11"prop, so a 9" prop is undersized which means maybe longer flight time. But if you're into big wingspans you need a "C". If your funding process is restricted, buy the "C". Too big, or excess thrust needs throttling down, but you cant exceed 100% on a smaller motor system.

I ran a C on the OV10 as a single pusher instead of a pair in the nacelles. Wouldn't climb vertically, but that was the only restriction.

Thank you Piotrsko!

The 9x4.5 will work just fine on the explorer 👍

The C motor “can” spin an 11” but only on 3s, and I wouldn’t go full throttle for long periods of time. 9-10” is best.

You can't go larger than a 9 on a stock-built Explorer. It will strike the tail boom.

Why would you run a "C" on 2s? Sure aint gonna get long runs before esc cutoff. I run a 12-8 gasser prop because the electric ones only give one flight before breaking, the gasser prop is from 1974

I said 3s…
