Quadrocopter - Part 8 - Failure

Image
The quadrocopter project was going fine till i decided to start soldering the circuit for the flight controller. I've burnt my hand countless times while soldering - frankly speaking im lousy at it - but this was worse. I was powering the circuit from the BEC (Battery Elimination Circuit) on one of my ESCs. As it happens due to the genius of my soldering technique i accidentally shorted the GND and the VCC of the BEC together and as soon as i connected the battery there was a crack sound and the inevitable distruction of the ESC. Thankfully we did have a spare ESC at home that was being used in a hovercraft project that my flatmate was working on so that got sorted. The Burnt-Up ESC. After that things got worse. The maiden test flight - not conducted by me - of the quadrocopter (done just by connecting the ESC's to the RF receiver with no gyros and no control circuitry) did not go well - as expected - and the entire thing just flipped over after going about 8-10 fee

Quadrocopter - Part 7 - Updates

Its been about 2 months since I've written about anything on the blog. This was mainly because i got lazy and partly because i had nothing new to report. So now for the updates on the quadrocopter project. Firstly i got the pyramid ready and fixed on top of the  quadrocopter .This is how it looks: Note:The RF Remote in the pic is not the one im using now. This was just a temporary 9ch radio that the people at RCHobbyAddict.com sent me until the ones i ordered arrived. It was freaking awesome though. I also added some acrylic sheet pieces to be used as landing gear which was not a very good idea so i replaced them with some foam pieces - they work extremely well. I also measured the weight of the quadrocopter and it was about 1.7Kg (including 2 batteries). I then finally received the the RF transmitter and receiver that i ordered ( Hobby-King   2.4GHz FHSS 6Ch Tx-Rx   - Mode 2 )  from RCHobbyAddict.com at a reasonable price.This worked rite out of the box and all i
