I am very happy with my Tevo Tarantula 3D printer! I have it up and running for about 6 weeks now. Let me tell you about my prints so far! Reading all the forums, facebook groups, and of course the Tevo website, I decided on the way forward after finishing the build. First, I would need to be able to print dimensionally reasonably accurate parts. In order to achieve that, I fist took a  look at the extrusion. It is important that the extruder extrudes the commanded length of filament, to within a few percent. To check that, I fed in the filament for only a few centimeters. With that as "0", I measured 120mm from the infeed side of the extruder, and marked the filament with a black marker. Then, I commanded the extruder to feed 100mm into the teflon tube, and mesured how far from the extruder infeed side the mark ended up. That should be 20mm, of course, but in my case it was less than that. So I had to tune down my extruder a bit. As I measured 17mm, it had "over-

The GearBest GB X155 Kit is, of course, available through GearBest . This nicely priced kit includes a video camera, transmitter, and goggles too! So it is aimed at first-time FPV pilots, like myself. Let's see how a target group member copes with assembling all these bits and bobs into a flying machine... What you get is a big box with little bags of parts, and a couple of smaller boxes for the Runcam camers, the Aomway antenna, and a bigger box with the FPV goggles. Let's start with the motors, because they are one of the major performance components. In this kit, you will find 4 Emax 1306, 4000KV RS series motors. Thay produce a little more torque than the 6000-7000 KV tiny motors that are out there, so they can handle three-bladed props with slightly higer pitch. The props that come with the kit are 3035 three-bladed bull nose props with no particular brand on it. I ordered some Gemfan replacements for them, for when I crash (it's not IF, but WHEN ;) )
