    very cool. :-)
    How big are they ?

    But with deltas you just print to the height where it's the top of the cylinder. never heard of anyone doing the cone thing.

    wow - bigger than i thought.
    so how much thrust do the little motors have ?
    And what do the batteries cost ?

    oh yeah just ordered a 220x220mm sheet of pei from china.
    under ?5.
    did think about printbite - but that's not doing it on the cheap :-)

    the 50mm edf with the 4s battery should produce 770-790g of thrust. And the batteries were cheap. I got 4s graphene lipo batteries for ~$20 each. From right here: https://hobbyking.com/en_us/graphene...ah-4s-75c.html

    cool - just ordered printer that look remarkably like this one of yours:


    any chance you could post or send me the file for your print cooling duct thing. Already got a spare turbo fan and I can see two dedicated fan sockets on the board :-)

    So what will the planes weigh ?
    Ie: what's the thrust to weight ratio ?

    And what are you glueing them together with ?

    using cyanoacrylate instant glue. it seems to be working well with the PLA. Not sure abut the weight just yet. But i am getting there and will post up those specs. Also there are specific points where i need the make the plane balanced. The motor and battery setup I am using is supposed to be good for 780-790g of thrust.

    And the incredible titan aero fan duct I am now using on all of my machines I downloaded from right here: https://www.thingiverse.com/thing:2941191

    Wow. It has been a while since I updated this thread. Well I still use this printer regularly. I have updated the firmware on my machine to marlin 1.9 and I have updated the firmware in the touchscreen and I am using Prusa Slicer 2.0 which as I understand it is the latest version of slic3r. Printalicious looks awesome with the new build surface..And the new project of the day is this model LS3 engine I am printing out. This printer is making my exhaust headers out of silk gold PLA..
