Yes, no grease on the rods, I was talking of the spindle and screw of the z-axis drive. The rods just need some light oil.

Thank you very much, for sharing your experience. I looked at their page http://www.orbi-tech.de/shop/Kunststoff ... 30_46.html , did you try the pla90 as well? The graph indicates, that pla45 seems to be more flexible, than the others, maybe somewhere inbetween "standard" and the soft type. And, regarding to the graph, it looks like this type of PLA45 starts to soft below 50°C.

Hi Daid, my Ultimaker is not here yet, but I own a CNC. You will definetely need to regrease it from time to time. I got no special interval for this. As soon as I see, that the spindle gets drier, I put some on it. If I don't regrease the spindles on the CNC, they tend to block, so this is absolutely neccesary. Any good machine grease will do, but avoid oil on the spindles. I use mostly a stuff called "Plastilube", don't know, if you can get it at your place. As there is not much movement on the spindle here, I think once a month of heavy printing, should be ok. Cheers, Micha

Hi, I tried 123d as well... it's beta, lacking lots of features and has its own approach on constructing. But some things are just nice, decent chamfer, punching, etc... super cool curved surfaces all around. Actually I do my stuff in 3Dsmax, what is somewhere inbetween technical and stylish modelling. Especially chamfered edges, that have been booled, don't come out well in max. OT, well, I just love your project and thank you for keeping us updated about it. Actually I am doing rather something similiar at the moment, but started with a 2DOF GoPro gimbal and drawed the copter around it. Made some copters out of carbon and aluminum, this will be my first with own printed parts. Cross the fingers for me . I like to have a dedicated copter for acrobatics, FPV, and gimbal... Why do you waste your time with the keycam, when you own a GoPro? The way the top layer was printed, just rocks! Awesome .

hi, The support answered me latest within a day and did a great job answering my questions so far. You will get the shipping information as soon as it takes place. Expect at least 6 weeks from your payment confirmed date. Cheers, Michael

Order #100001166, Payment confirmed 30/Dez/11 Tracking number received 30secs ago (09/Feb/12). Told my boss, he won't see me next week!

Hi Daid, "KV" is the RPM/Volt rate without load (no propeller on it)... there are lots of discussions, if KV isn't against any norms, or not . "ESC" is the electronic speed control, used to generate the high current pulse signal needed for the three phased motors, out of the (e.g. ppm) standard signal from the receiver. Don't know if there is a comprehensive list of all terms used in hobby-electronics, but I would be grateful, if I had one. :mrgreen: It's as easy as reading things about PEEKs and whatever terminology the printers come with, hehe.

Hi, love the stealthbomber looks of the canopy. What would you think about a more bajonett style plug'n'turn solution to hold the arms to the center? Or just a cotter? Interesting sound graph, didn't expect a second spike at 16Khz. I got 920KV Roxxy motors here, they whine terribly with any 8khz ESC i tried. Switching to 16KHz made them smooth. Propably lots of design, winding and other things are counting here as well. I don't have a specific experience with any brand or type of 16KHz ESC, sorry, last ones I used was Hobbyking's 30A brand. Keep in mind, that the FETs on the ESC at 16khz get warmer than running them on 8khz. Be sure, I will be the one of the first ones, that print this frame, if you like to put it online ....as soon as my printer comes... Cheers, Micha

Hi, thanks for sharing, pretty neat build. I am in copters as well and I yours look pretty well made. You mentioned the high pitch sound in your video, well, thats not the high KV motors, thats the 8khz ESC. Have a look for 16KHz ESC and you will have, what you are looking for. A 1000KV rated motor would be the best guess for that size. Maybe something to fix the arms into the cross, would be a great improvement. I tend to fly a bit acrobatic and it would be a shame seeing an arm coming off. Can't wait to receive my printer... I know, what to print first . Is it PLA, or ABS? Will we find it on thingiverse? Tried the GAUI in phoenix a few days ago... well... not the best simulation. It's many times harder in real life. Cheers, Michael

Definitly +1 for the SteamPunk mod! The big question about this is: How did you manage to wait that long, with all the parts on the table until assembly? My patience wouldn't last a minute longer, when my package arrives :mrgreen:
