My little rubber-band-powered 0.8 g straw plane

|
+0
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)

Unbricking TURNIGY ACCUCEL 6 80W

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...

Modifying battery cell circuit.

In this article I’m going to describe how I modified the battery cell circuit for a TGY 5000 6S. Recently, a European Hobbyking retailer sold out these batteries, but they wouldn’t do unmodified, because all my equipment designed for 3S. Another problem was that there were no batteries with capacity that could meet my voltage requirements, and I couldn’t physically or financially afford to buy a whole batch of different ones. Therefore, I decided to buy these batteries and tailor them to my equipment. Please, do not comment on how correct my decision was, let it be on my conscience :))

Well, here is the donor, let's go:
