I think you can upload this at photobucket as well, but youtube is easy when you made an account.
I'm looking forward to it!

btw, you can gain some efficiency if you add a nacelle around the shroud and thrusttube. The area behind the intake radius gives a lot of drag.

Hi Erik,

must have a look... Perhaps i can find a Yoghurt cup or something that fits around the EDF
Don't wanna have too much weight you know.

A simple 0.3mm ply cone would be great and light. You might have to add 2 ply rings (one behind the radius and one at the end of the tube) to glue it in place.
In this link the nacelle cone is used as thrusttube as well to save weight (and I'm lazy and do not want to make a thrusttube )

Hey,

that's pretty cool with that wooden nacelle
I think i can build something like that wrapped in 49g/m² Glassfiber...

Thanks alot for that Tipp

I did cover it in 49gr cloth and spray painted it (Motip rattle can). Just make the glass cloth pattern a cone too!

Thrusttube is alredy assembled, just need that nacelle
