Whatever speed you got on that propeller, is it not a bit tiny?
Would it push enough air? I dont have that prop so I cant test for myself.
But of the images I've seen so far it looks like a bit small blades and not
enough angel to give enough push for the heavy LEGO craft.
And I have tried a lot of configuration for a propeller this week and always
goes back to the simple construction with the to Technic Fairing Panel #20
or #21. But I've also testet the smaller ones #22 and #23 (dont have the
part number for any of them). The propeller does get more rpm with the
smaller ones but do not push that much air it seems.
Anyway I have the trouble of getting a strong enogh motor for this
configuration so I will continue to search for a propeller built of LEGO
that can be good enough with the 9V motor supplyed with a traditional 9v
batterybox.
