Let’s go the limit... or CNC out of nothing.

No, no, nothing but a little piece of 15mm plywood sheet, a dozen of self-tapping screws, a couple of obsolete Epson printing machines, and a token of skill and expertise, right?

My little rubber-band-powered 0.8 g straw plane

Hello, dear hobbyists! It’s quite a while since I went in for RC aircraft modeling, and it was then that I came across a video. It all but knocked me off my chair: it showed little planes hovering for about 10 minutes. I thought those were some extremely sophisticated RC aircraft. After digging a bit of info, I realized that those were rubber-band balsa planes and I wouldn’t make one, so I exited the page. Well, I’ve been in it for 2 years, so I have come across the vid again. It is summer, so I don’t need to go to school and have plenty of time. I read some forums and, to my great frustration, I realized that I was too broke to buy balsa (I do have a little cash, but I need to buy equipment for my RC Cessna). My great thanks to Vyacheslav Tchabanenko for a decent piece of advice! Straw is a material that paves my way. We have bluegrass growing in our yard: just go and take as much as you can hande! Then I found a simple drawing and built the aircraft. And now let me tell you how Ito build a decent piece without a penny in the wallet. Here are the specifications:
Weight: 0,8 g
Wingspan: 160 mm
Length of the fuselage: 130 mm
Duration of flight: 30 sec

Several years ago I bought a once cheap Turnigy charger for LiPos at Parkflyer, and it went whack after a couple of months.

Dear friends, hello again!
I'm continuing my big and light-weight foam RC aircraft column, so here are the stages of building the legendary Yak-52. I'm not claiming perfection, this one is going to be a semi-replica.

Let's go.
Wingspan: 2m
Material: laminate flooring underlay
Propeller: TGS Sport 17x10E Precision
Motor: HobbyKing Donkey ST4010-820kv
Speed controller: Turnigy Plush 60А с BEC 3A Brushless
Servo: HXT900 (9g)

Hi everybody!
One day I decided to reflash my charger. I downloaded an archive from this page: http://www.hobbyking.com/hobbyking/store/uploads/1019411227X1816993X33.zip
The archive contains DFU firmware and two firmware images: the original version 1.13 and a patched one, which does not require a balance connector. I chose the patched one.
I did it all as written in the manual: open the file, typed in VID 0x0000, PID 0x0001, click UPGRADE...
Briefly, I did it at work on a laptop with a bad USB port.
Well, it didn't go through. The laptop wouldn't detect it.
I've got a brick :(

In the first part of my story I have told how my son and I had become acquainted with Arduino and also I have told about first steps (or rather meters) of the robot composed on Arduino Uno 3 board. Now it’s a time to tell more about our construction job.

Hi, I would like to show you yet another kid's-stuff little monster. I drafted it a long while ago and made up my mind just now...
