Look ahead position estimation using the last three GPS points and drone speed.

Hi,I've created a working antenna tracker for my hexacopter with a MultiWii controller using a spare Arduino Nano V3 and an XBee Pro 900 pair. MW protocol is decoded and GPS LAT/LON/Speed and ALT…Continue
Arduino Float / Double lack of precision when processing GPS coordinates.

I've hit a bit of a road block on a piece of code I am using to calculate the distance and bearing from a home position to the drone's GPS LAT/LON. I'm using this code to drive an antenna…Continue
Increasing yaw authority on hex
Started this discussion. Last reply by John Grouse Oct 27, 2012. 2 Replies 0 Likes
Can anyone tell me if I should change my hexacopter motor angles to try and increase yaw authority? I'm sure I have read somewhere that 3deg one way for the CCW motors and 3deg the other way with CW…Continue

John Grouse commented on Andreas's blog post RCTimer Brushless Gimbal and Controller"By drift do you mean that it starts to drift from level and stay at that drifted angle?
An example of what I am seeing is that if I throw the vertical support arm to the left 45 deg reasonably fast I notice the roll angle tilt to the left by about…"
John Grouse commented on Andreas's blog post RCTimer Brushless Gimbal and Controller"Is this the RCTimer Open Source "Martinez" based board?

John Grouse commented on John Grouse's blog post Carbon Fibre Brushless Gimbal for NEX and smaller."Slow progress on the prototype. Changed the lock tabs to closed loops for extra strength. Just needs a CF peg pushed through the hole to lock the plates in place. Feels very solid.

John Grouse commented on John Grouse's blog post Carbon Fibre Brushless Gimbal for NEX and smaller."Thickness is a large factor to the rigidity of the CF.

"Sorry for the off topic, but it's kinda related to gimbal construction in general.
R, your CF must be different from what I have. Comparing a CF and Alu plate there is no competition. CF wins every time. Especially if the plates are <1mm…"
John Grouse commented on John Grouse's blog post Carbon Fibre Brushless Gimbal for NEX and smaller."I'll do the smaller GoPro design once I perfect this one. Should be a matter of scaling it down.

Carbon Fibre Brushless Gimbal for NEX and smaller.
Posted on May 28, 2013 at 4:30am 20 Comments 3 Likes
I now have an RCTimer OpenSource BGC board ("Martinez") and a couple of LD-Power Gimbal Motors which are large enough for an NEX or smaller. I looked over a number of BGC frames for sale but they all seem to incorporate metal or glass fibre, both of which do not have the same strength and low weight of…
Antenna tracker for the MultiWii platform using MW V2.1 protocol.
Posted on November 29, 2012 at 8:10am 40 Comments 5 Likes
Just spent a couple of hours getting my head around the MultiWii V2.1 serial protocol. This involved looking at EOSBandi's MW-WinGUI Visual Studio c# code and adapting the essential bits I need to a simple test VB 2010 app. The app sends the commands to get the GPS bearing and distance to home as well as the…

Was getting annoyed by the stupidly heavy frame of the Scorpion Y650 which is made of thick fibreglass sheets (available from Hobbyking). With the GoPro sitting on the camera gimbal and a 4S 3000mAh battery I was only getting 6-7 min flying time.
Had a look at the price of CF sheets and CF 450 size heli…

I've been looking at my unused twist grip joystick for a while now thinking about hooking it up to a transmitter via the PPM trainer port.
I might go a step beyond this and get a new 2.4GHz Tx module and add that to the joystick to make it a transmitter.
