I need to acquire a DSM2 transmitter. Either a Spectrum/JR module and a Turnigy 9X transmitter (because I like the idea of an open source transmitter), or a Spectrum 5i (because a friend has one he's not using that I can borrow). I don't know if the 5i has a 3 position switch, I'll check it out before buying the Spectrum module.
anticipated AUW ~1kg.


My plan is to make a robust and strait-forward quad the easiest way I can find, and learn to fly it. After that, I'd like to switch to 36 MHz PPM control or fly by telemetry (joystick) to free up 2.4 GHz for analog video.
The powertrain spec is similar to what most of the VC-450 setups on the RC Groups thread have, but I suspect that (on 3S lipos) those motors/ESCs will be slightly under-propped (wasted weight). My main concern is that the controllers won't be fast enough, expect I may need to replace them with something better. The props feel a little flimsy and I will certainly be balancing them well before I use them.
 
I still need to acquire a DSM2 transmitter. Either a Spectrum/JR module for a Turnigy 9X (open source firmware, it's just an AVR with the right inputs), or borrow my friends spare Spectrum 5i. I'll find out if the 5i has a 3 position switch, I'll check it out before buying the Spectrum module.

Aerofu logo.png

I'm a paparazzi enthusuiast from Canberra (Australia) and the guy behind aerofu.com.

Who is this rufus character ?

  • My name is Chris Gough, some people call me rufus (for reasons I don't fully understand).
  • the best way to reach me is christopher (dot) d (dot) gough (at) gmail.com.
  • my skype identity is christopher.d.gough, but it's not a good way to reach me.
  • I rabble-rouse on GitHub as monkeypants.
  • my eBay persona is monkeypants007.
  • my phone number is (+61) 418441605 (a mobile).

I'm NOT this guy:

I mostly fly fixed-wing foam planes with Twogs/Tinys and IR;

Current project: Lisa/M Quad

I am currently gathering parts for a my first Quad project, which also be my first foray into STM32 paparazzi. So far, I have accumulated:

  • Lisa/M with Asprin (yay!) and a JTag thingy.
  • orderd a VC-450 quad frame, expect to have it soon.
  • These 1000 Kv motors, these 30A ESCs, and these 12 pairs or 10" * 4.5" counter rotating props. I have no idea if these are any good, or even if they are fit for purpose, I only know they cheap.
  • 2 Orange DSM2 satellite receivers from HobbyKing
  • 900Hz xbees (international firmware, 915-928 MHz and power limited to fit withing the Australian ISM class licence)
  • a new design NEO-6Q GPS (will fall back to a LEA-5H if this creates problems), etc
  • plenty of lipos, picoblade bits and pieces, etc.

anticipated AUW ~1kg.

The powertrain spec is similar to what most of the VC-450 setups on the RC Groups thread have, but I suspect that (on 3S lipos) those motors/ESCs will be slightly under-propped (wasted weight). My main concern is that the controllers won't be fast enough, expect I may need to replace them with something better. The props feel a little flimsy and I will certainly be balancing them well before I use them.

I still need to acquire a DSM2 transmitter. Either a Spectrum/JR module for a Turnigy 9X (open source firmware, it's just an AVR with the right inputs), or borrow my friends spare Spectrum 5i. I'll find out if the 5i has a 3 position switch, I'll check it out before buying the Spectrum module.

My plan is to build a robust and strait-forward quad, then learn to fly it. After that, I'd like to switch to 36 MHz PPM control (like my planes) or fly by joystick to free up 2.4 GHz for analog video.
