I bought the same gimbal without seeing this thread. How did you mount it to the frame? I have it without the stock suspension on the TBS loveseat using two zip ties. Please share your way of mounting it. Thanks.

MacFly   May 07, 2017 

Great question! It wasn't very straightforward tho I'm afraid:

  • Cut all power traces going to the front of frame where the core usually sits. (to avoid any short circuits after the next steps)

  • Drilled the discovery plates for a new standoff mounting point (about 74mm away from the original).

  • Cut away most of the bottom plate's action camera "seat" to allow maximum gimbal movement.

  • Took the tiny2's stock alu mount and bent it at 90° in 4 places. (not a trivial task, bending near the tiny bolts while keeping the distance to a minimum was tricky to say the least and chances of ruining the parts are high).

  • Isolating mount goes as follows: standoff -- silicone fuel tubing -- small FC dampers -- big gimbal dampers -- tiny2 alu frame. (silicone tube could probably be omitted making assembly easier). Once (finally!) together and tweaked to fit (bending alu arms), bolted into frame as one piece.

Another option I considered that doesn't involve the tiny2's alu bracket was to use http://www.goodluckbuy.com/8mm-tube-clip-fixed-rubber-anti-vibration-adapter-for-quadcopter-multicopter-landing-skid-4pcs.html and make a plate from FR4 or carbon fibre plate to join the goodluckbuy mounts to the tiny2's four little bolt holes.

Added a few pics to give a better idea of how it went together. There is little room for error, about 1mm top and bottom and right where the bends are the alu is pretty much brushing the PCB plates (4 square holes could solve this).
I'm happy with the result, it's quite neat and works beautifully.

Hope that helps!

Wow, it's been a while since you posted this. Did you just now take some photos? How has it been performing for you?

Yeah I've seen some amazing footage with the tiny2. Got anything up to show how it performs?

MacFly   Oct 02, 2016 

Haven't flown the tiny2 yet! Should be more than capable! I just hope its performs well without the stock suspension mount..
If not, you might see a XuGong appearing here xD

Finally got a flight in with the tiny2, and I must say i'm very impressed!! Bottom plate needs more trimming to get it out of the way during faster turns but here's a look:

Started getting your parts yet?

MacFly   Oct 08, 2015 

Almost done!
I suspect the dampers are too soft, might have to stuff 'em. Failing that, an order to fox tech for stiffer dampers.
Looking at the landing gear left over, I could bolt the CF tubes to the top frame, and hang a 3axis out the front...

A wise man once said: People think you can just research and buy "the right things" and be done, when in reality you'll just end up slowly buying ALL things.

These are what came on my gimbal, Anti-Vibration Rubber Damper Damping Ball for Gimbal Gopro DJI Camera BLK. They're fairly firm and offer a good amount of space between the plates to accommodate most boards.

Whiffles   Sep 25, 2015  

Wow, that looks like a very thorough parts list! This should be a nice rig. Are you currently waiting for the parts or have you not started ordering yet. My only suggestion is to swap out the 2-axis gimbal for the Goodluckbuy StorM32 3-axis gimbal.

I'm waiting for a Xiaomi Yi that can do 4k. I can't imagine we're very far off. The GoPro 4 has been doing 4k for some time now. Upscaled 1080p can't hold a candle to 4k on my monitor.

MacFly   Sep 26, 2015 

You may have to wait until well after the release of a "hero 5" with the H1 chip. Then we might see the A9 in a Xiaomi doing 4k@30fps. But then you will be waiting for a Xiaomi with a H1..

I'm not holding my breath. For now my Yi is great and the footage is quite acceptable, but I don't think I'd want to crop it.

This guide will walk you through the process of building your first FPV quad. The goal with this design was to build a low-cost, lightweight quad, yet powerful enough to safely carry a GoPro in close proximity areas. I chose these parts to minimize the amount of soldering at no cost to the quality. A typical build requires around 30 solders while this only needs 25. It's not a huge difference, but..

In late 2019 DJI made inroads into the FPV scene with their remarkable low-latency digital system. It gave us a 720p video feed with latency on-par with the status quo, analog video. Traditionally we've used analog video systems for low-latency video, but the video quality is far from ideal. It's a trade-off we've been willing to accept for the control. Now we've got the best of both worlds and what..
