Attention: RC-CAM.com will be closing down August 2021.

The RC-Cam.com forum was the very first online community dedicated to the advancement of wireless video cameras on radio controlled (R/C) models. This is now called "FPV" (First Person View). We are proud of the contributions that our members have made to the FPV hobby.

We've seen significant changes over the last twenty years. Initially there were a lot of eager R/C hobbyist that built their own video systems. Allowing these creative individuals to share their work was the purpose of this site. Now the FPV market is flooded with low cost systems; Sadly DiY FPV video projects are now rarely discussed.

RC-CAM.com (main site and forum) will be closing down August 2021. This is being announced now (March 2021) so that everyone has time to download any information that is important to them. After the site is shutdown the information will no longer be available here.

We appreciate every member's involvement with advancing the FPV hobby. It is indeed sad to say goodbye to all our online friends. Be safe and stay healthy.

Questions about component placement on Gaui 330X-S

Recommended Posts

I am going to install the following devices on a Gaui 330X-S.

  • Fyetech FY90Q controller
  • ImmersionRC 600mW 5.8GHz A/V transmitter
  • EzOSD (consists of 2 boards: GPS module and current sensor module)
  • Futaba R6108SB 8-Ch receiver
  • a 3S 2100maH Lipo battery

I'm seeking advice about the optimal placement of these devices given the available space on my Gaui 330X-S. The attached pictures should illustrate this.

Given what I've been able to glean from available documentation, here's the component placement I've come up with (side-view and top view pictures are below):

  1. The battery can ride atop the Gaui "payload" board that forms the very top layer of the 330X.

  2. The EzOSD GPS module must face the sky. I'd like to know exactly how much of it must face the sky because in my uninformed opinion the best place to locate this module is peeking out from beneath the battery.

  3. The push-buttons on the EzOSD and the trim pots on the FY90Q need to be easily accessible, so I figure the FY90Q can also ride beneath the battery in its anti-vibration sling with just the trim pots visible. The Futaba RX can also fit somewhere on this layer.

  4. The A/V transmitter can be attached beneath the 330X center core just above the z-axis (panning) servo shown in the picture. I thnk the EzOSD current sensor can also ride beneath the core but that's just because I can't think of a better place to put it.

In summary, can you offer any rules or suggestions about the optimal locations for all these devices?

1. I prefer to put the large mass items (like batteries) as low as possible. Besides doing less damage to other things in a hard landing / crash, a lower CG may help with stability.

2. For reliable/fast satellite locks you do not want to obscure the GPS patch antenna's view of the heavens.

3. Good place.

4. You should position the wireless video Tx as far away as possible from all the electronic items. Otherwise prepare to experience EMI/RFI issues.
