Basically it would be great to just replace the inner swash ring and replace it with one that has several threatedholes like the Rakon Heli has 4, just with like 3 or 5 or even six attachment points for linkage balls... "That would be all"...

One guy did a 5 ball swash in Austria and got a fully functioning 5 blade head.

Default 4 blade test flight... and crash!

I built my own machine 3/4 axis machine, I couldn't give you a cost number (fear and not knowing) several k, that's for sure though, but I used linear guides, ballscrews, and a brushless drive/cartridge spindle. All it lacks at this point is a tool changer which will be coming soon enough. Good cam is expensive, but for 2.5D or even simple surfacing you can get stuff for a couple hundred or so, even free in some cases.
If you have things you want cut I can take a look at it. If it's something I'm interested in making for myself I'm generally happy to make two at the same time, send you one for your trouble of designing it.
Actually that apprentice sucks more then I would have loved to know about...

I today, finally put a tail with a longer solid CF rod and Astroid motor holder together, put in the CO5 brushless motor in and added it all to the 4 blade head.

There is a lot of torque in the 4 blades (using the Mini CP blades from Walkera)... especially with the brushless...wow (but the regular motor didn't cut it). The tail still has the 6mm motor on and it does not hold well, the SR 120 motor with torque tube is in the works... but anyhow...
The strange and actually nice thing is/was that the bird is much quieter 4 then with just two blades and it is solid in a hover and it flew beautifully. I haven't finished the anti-rotation and the metal linkages were supposed to be tested on the third flight.

Okay the second flight... everything was smooth until a did a to quick cyclic input and I think I bend one of the plastic links... so I quickly went for a landing and hit throttle hold but one of the blades struck the corner of a cupboard... no buggy I think as in the same moment the blade with the blade holder still attached comes flying in my direction... crap. How??? That was a miner struck no buggy I did that a hundred times with the mCP X before...

So I inspect the now broken custom $40.- bucks a piece feathering shaft... This guy actually drilled all the way through the shaft to attach the M1 x 3mm screw from the original feathering shaft... he was supposed to drill 4mm maybe 4,5mm but not all the way through...

To make matters worse... two more are bend!!!

I guess I have to pay this guys a visit tomorrow... I hate that... darn...


So the fact is, it flies, it flies quite well... we'll have to see if it does like a 2 blade once I have finished the anti rotation collar and mounted the metal links... but with these feathering shafts made out of butter... we might never know...

I'll report back...

Fly Safe!

might i recommend having your next set dipped to harden them? it looks like they are bending before they break, personally on a head piece i would rather a clean snap then a bend.
