"What plastic are you printing with ? PLA or ABS ? I print with PLA, and i have no heatbed, on my build platform i have blue painters tape. Also you might wan't to print the arm with the foot (circle) under, i did make it to stick better to the…"

"What is the inside diameter of the motor mount?  I am looking for a replacement motor."

"Hi Peter , I'm wokring progress to print your project with my first beta revision of MultiMaker32 :) This is a video of print your quad ... some suggestions ... how is the temp of extrusor and the of your bed ? What is your speed of…"

"The PLA arms do not warp and they do not flex (i print them standing).. So far i have only printed in PLA, i don't know how they would be with ABS.. I have an Ultimaker, and i use replicatorg (0025) and skeinforge 35. There are newer versions…"

"Great Work Peter :) I buy a Reprap Prusa , and now i'm working around to try to doing good print but is not so simple ;) Do you know reprap prusa ? What software are you using on Makerboat ?  How is simple the calibration ? This is the…"

"Ha! Nice demo.  It's strong, but no warping?  They always come out straight? I also designed a 3D printed frame, but using the SLA printers at Shapeways.  That nylon material is also pretty tough too. "

"I print with PLA plastics, and there is no issues at all, and the arms are very strong.. http://www.youtube.com/watch?v=RwZ5aTlU0iY"

"That's very interesting.  Any problems with printing those arms? Isn't it too long to get straight prints, due to the difference in cooling rates of the plastic?"

"Looks like it is supposed to look like a bird from the ground.."

"I now see that the tubes look different :-) that might explain it.. no hole in the top of one ?"

"Very nice ! But are the airspeed sensor correct mounted ? Am i wrong if i think only one tube should be on the front in the airflow and that the other should be not in the airflow, and the speed is the difference in pressure between the tubes ? Keep…"

"Very impressive ! To reduce time, you could build a magazine holding several GCPs (discs or small cones ore something) and have the multicopter first go and place them for you !"

"It's cold here. I don't want to be cold. I'll fly the sim till the sun comes out and it warms up a bit."

"good find! i bought one too. but like the rest of you, I am afraid to strap it to an aircraft in this weather."

"received my camera from hong kong yesterday. Will strap on to my Easy Glider when the weather in Salt Lake is better for flying. I'm a wuss, so it's got to get a bunch better."
