Why future racing copters really should look different.
by Dr. William Thielicke aka Willa aka Shrediquette
ABSTRACT
In this article I try to demonstrate why FPV racing multirotors need to look different. Some small modifications to the frame would (in theory…!) result in 70 % higher top speed! All that needs to be done is to align the arms parallel to the propeller flow, and to tilt the main body of the copter by about 40 degrees. I am presenting a very simple and robust racing copter design that incorporates these ideas. Furthermore, I am calculating the aerodynamic drag of different copter concepts using basic equations. The aim of this article is to make you realize the importance of aerodynamics and to stimulate people to design more innovative racing frames.
INTRODUCTION
Until recently, multirotors were mainly used as a “hovering device” and the top speed of these copters did hardly matter. Now, multirotor racing has become popular and all competitors are seeking for very fast…
Looks excellent - I have bought the parts and will be building during the Christmas Holiday. I will let you know how I get on.
ReplyDeleteI would like to use an ATMega32 that I have already - if I change the def file name is the software likely to compile and work ok?

Hi Peter,
ReplyDeleteyou can most likely use an Atmega32, but I would nevertheless recommend an arduino mini pro. It's cheap, small, light and handy. I assume that you know how to change the circuit and that you have Bascom + an ISP programmer? Because otherwise it will be complicated for you if I release new firmware.
So my recommendation is: Pay some 14 Euros extra and get an Arduino.
Thanks William.
ReplyDeleteI have built a number of projects using processors from an ATMega16 to a 644P and BASCOM so I would not have any probelms (I hope) replacing the Arduino with a processor, crystal, etc. and programming using the ISP port.

ReplyDeleteGrazie william per il set-up manual lo aspettavo con inpazienza molto ben descritto
la costruzione del cubbo.
ciao e scusa per litaliano.
