Hp peak is at about 23k, so in rough numbers yer looking at 46mph tops on 2" pitch and 69mph on 3" pitch. Or 56-57 on 2.5" pitch.

That Cox 3.125 x 2.5" 3 blade is about the only off the shelf glow prop with more than 2" pitch for this engine. Ugly looking POS though, can't imagine it is one of the more efficient choices, but ??

What are the chances of success repitching a 4.5x2 then trimming it down, I wonder..?


Think you got problems? I found an old post in another forum - someone was complaining about the lack of choices of pusher props for electric motors.. okay then..
