I too am an ex model plane fanatic, flying everything from super fast foamies, through to 111cc 10ft wing span fully aerobatic models, I even entered a couple of competitions at one point The 4 blade fan I have just tried, suffice to say you need a VERY light chassis with VERY free running bearings. I am going to use 3mm ball bearings in mine once I design it. Not the most efficient prop I have ever seen, maybe the 2 blade might be more efficient?Phil.P wrote: ↑Sun May 22, 2022 11:37 am Steve, Rik,
Many thanks for your efforts! - I did wonder if a propeller / fan would be awkward to print..
Quite a complex shape to draw.
Having messed with model planes, in a previous life, It will be interesting to see the result.
Thank you again! - Now all I will need to do, is finish them.

I have had to make a couple of change to the CAD work as the motor does not fit unless you want to take out 0.3mm manually, so I have redesigned one with a 0.4mm bigger hole, this works and is far easier to fit a motor inside. I have also changed the back plate for the same reason. Just reprinting them now.
All the best
Steve
