Summary

So I got frustrated by my larger, complete redesign of my arducoper, and instantly fell in love with brucedjones's bodgie design. I also really want to do FPV so I redesigned the way the Aeroquad board mounts to allow for an X configuration. I did this by moving the arm mounting holes out about 1mm, So you can still choose a Plus configuration if you want.

The lower platform was designed extremely quickly as burn out was starting to set in here as well.. A quick GoPro mount was added to this and I had plans to make a quick AV transmitter mount, but booleans and maya weren't cooperating...

I have just rubber banded the RC rx to one of the arms for now, but may look into a more proper way to keep it on.. Maybe an upper cage to protect electronics and constrain wires?...

I have really only flown once so far.. about 3 minutes of hovering around while mosquitoes were trying to eat me..

It oscillates a little with the 1500mah batt and I had a few hops with a 2200 and it was really unstable, so It will need some PID tuning..

FPV electronics and Gopro may make things a bit heave, esp with a 2200mah batt..

Though holding in my hand at about 2/3 throttle I was showing about 10 amps coming out of the battery, which is a bit promising.. between 1/2 to 2/3 throttle seemed to be about hover position.. again only one flight and distractions..

Instructions

Aeroquad board assembly and programming is extremely straight forward.. just follow the wiki..

Though I spent 2 days thinking my sensors were bad because I didn't RTFM (RTFW?)and just looked at the pics when soldering..

Other assembly is pretty straight forward as well.. gotta love the simplicity of these things..

Organizing wires and mounting the battery is probably the trickiest part.. may need a specialized part for that eh?..

EDIT: Follow brucedjones's instructions for the power distribution board or there's a tutorial in the aeroquad wiki...

I like the colours, and wow a GoPro mount! Whats your prop/motor combo?

I havent had time to do much with Bodgie over the last month so I'm very interested to hear any and all feedback you have on the design. Some ideas I havent had time to pursue include:

  • Using only one mounting hole to mount the arms
  • Exploring prop and motor combo's for different lift/performa
    nce characteristics
  • Vibration isolation of the IMU
  • Adding some sort of "holder" for the esc's (cable ties dont look great, but they work so well!)
  • Routing the speed controller signal wires through the frame (Again i'm using cable ties for this)

Thanks! I printed your original design in blue, but had to switch to green for some other prints and just left it.. It does help with visibility..

Motor/Prop combo is 7x3.5 prop and Turnigy 2730-1500 1500kv motors..

  • One mounting hole is probably plenty, it seems to work for my setup

  • I've been wonder about vibration as well.. one trick I've seen is using several layers of double stick foam tape in small squares/cubes...

  • Using the top center pieces as both top and bottom gave me a nice flat surface tie them to.. I say function over form FTW!

  • Again function over form.. I kinda gave up on wire management at the end..
