Those black propellers look very good. How did you get them to print so cleanly? I tried using supports but mine turned out like your grey ones

Yes, I agree. I did look at the possibilty of volunteering when Phil first asked, but decided that the propellors would prove too difficult and kept my fingers off the keyboard.

Simple, I printed it without support on the flattest side. Tends to print better with no support than a huge area of support. I think they will sand down very nicely. :thumbleft:

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. :geek :geek

Thank you again! - Now all I will need to do, is finish them. :|

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?

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

Well... I can confirm the 2 blade is FAR more efficient, which is how I thought it would be. The 4 blade was super noisy, had to spin flat out whereas the 2 blade is half throttle and much quieter.

Here is the 2 blade, I did not video the 4 blade as it struggled to get around. I didn't try reverse, I will later, lol.

A couple or so pictures.

Please ignore all the lines on mine, they are done on lowest quality prints and are purely for testing. :thumbup:

Must admit, I didn't try putting mine together. I just printed them off. Hopefully, you should be able to make something with them, Phil.

Just so everyone knows, the fan is also way more efficient if you leave the protection cover off. I am not going to fit mine, if someone is stupid enough to stick their hand in a fan, which can only be accessed from the rear and makes one hell of a screaming sound, then who am I to argue with natural selection :dontknow:

Reminds me of a time, MAAAANY years ago at school. We had built a propeller driven, aircraft diesel engine powered, R/C controlled, racing car. In trying to start it in the normal way by flicking the prop, it kicked...and I still have a large scar on my finger to prove it! Back then of course, 'elf n' saftee didn't exist. However there was a positive bonus, my English Language O Level exam was the next day and I had a large dolly on my finger so a note was attached to my paper explaining that I was incapacitated... and that is how I passed my O Level at the third attampt! :oops: :oops:

Steve,
Excellent! That passed the smile test.
:thumbright: :thumbright: :thumbright:

I had thought a 'commercial' 3-blade propeller, might be an option?

Hoping to get mine in the post Wednesday for Thursday / Friday delivery. Not forgotten, just delayed.

Also my track brush has been keeping my very busy indeed in the spare micro seconds, I think it's on V4 now and still needs work :(

Honestly, my life is a soap opera, it really is, most things that happen are just so surreal! :shock: :dontknow:

Roll on more running days :D :D

OK, wrapped up, hopefully being collected tomorrow, so should be with you on Thursday.

A few little extra bits in there, hope you can make use of them. :)

Post has arrived...

Stern looks, from Domestic Authorities.. :? :lol:

One parcel from Peter Binnie. - Strange! I seem to have ordered four chassis. ;)

So now I have the major components of three 'Windy'..

Steve, thank you for the other bits and pieces. They raise a number of questions, but probably for a different time and place?

(But did you intend to drop a motor in the box?)

The power of the Community, wins again.
Another 'thank you' to you both.

Yes, I have loads and loads of motors and I just wanted to make sure you had something that fitted, it's a 3v-6v motor.

Hopefully all of the contents was useful?
