uReview – HobbyKing HK450 Tail Boom w/ Custom Laser Text

mattmc — Tue, 10 Jan 2012 11:38:46 +0000

The purpose of the uReview (micro review) is to provide a short, sharp review of some RC products bought online. Often I've found product pictures are ok but there's no telling really what you're getting till you hold it in your hands. So the first candidate for a uReview is a fairly simple one, the [...]

To answer a few questions about the specs of the Quad-Y-Copter (V-Tail) here are some details on the config; Motors: All four are rctimer.com 750kV http://www.rctimer.com/index.php?gOo=goods_details.dwt&goodsid=123&productname= ESCs: Turnigy 30Amp.

QuadYCopter video and performance review

mattmc — Tue, 03 Jan 2012 12:19:39 +0000

If you do nothing else, skip to 48 seconds in the video below and watch the crash when I hit a tree and land right side up. I ask you how many types of models / electric helis can you punish with that poor piloting and keep on flying? If that had of been an [...]

Optimising the QuadYCopter

mattmc — Thu, 15 Dec 2011 10:28:24 +0000

There's a few things I'm trying out to get the QuadYCopter as stable as the QuadCopter is; Three Blade props 4S Battery Shorten the front arms Restore the PID values to default Custom code. By far, the biggest change / improvement has come from using Three bladed props and a 4S battery. Some might [...]

QuadYcopter Maiden Flight video

mattmc — Mon, 05 Dec 2011 04:23:45 +0000

There's a few different names that might be applicable like a Y4, Inverted V-Tail, Y-Copter but I think I'll call it the QuadYcopter and it flies! All I had to do before this video was reverse the direction of two motors and it flew better than expected considering the lengths and angles are all eyeball [...]

Timelapse GoPro extended by external power source

mattmc — Sat, 05 Nov 2011 10:08:58 +0000

Ran the GoPro from about 2pm till 8pm on the upstairs balcony. I'm not sure how long the GoPro battery would last so I hooked it up to a LiPO 2650mAh battery via a uBEC. I checked the charge before and after and it had used about 40% or about 1060mA. I think the [...]

Tuning for auto-level – MWC Quad

mattmc — Sun, 30 Oct 2011 10:04:45 +0000

According to the instructions on multiwiicopter.com the mid and endpoints need to be set properly to ensure auto-level works properly. I hadn't bothered much with this except to make sure the throttle travel was low enough to arm the PARIS board. This is probably why I've spent so much time stuffing around with trimming flights trying [...]

mattmc — Tue, 11 Oct 2011 11:09:46 +0000

These photos show the frame starting to come together. The bottom of the CF plate shows each of the four ESCs are held in place by 2mm cable ties. There's not a lot of room left on the top of the board after the ESCs and power distribution cable is laid down. On top of [...]
