HQuad Foldable With DIY GoPro Cage Mount

This is my fourth attempt at this form factor and each one tried to correct the mistakes of the last one. I'll post video when I can hike in to some place interesting but just flying around the yard - definitely no jello at medium setting of GoPro2 and almost zen like in AV calm conditions - best I've ever gotten off a static mount! The mount obviously copies the concept of another well known but expensive (and brilliant) mount. I just put the GoPro inside. It DID take 3 different wire sizes and 2 different compositions to get all the vibes out of the AV. This was quite a bit more work than I thought it was going to be but well worth it. The whole thing as shown weighs about 1.7kg and hovers for about 8 minutes at half throttle. FCB is Hoverfly Pro.

Do you mind if I copy your design?

Go for it. I'm sure you'll find ways to improve it. I found that 17" works, motor to motor, with 10" props. Any larger and it won't fit in the pack. Any smaller and you need to go to 8" props and she will no longer carry the camera. Good luck!

Description:

This is my second wooden frame, an FPV spider quad inspired by the Hoverthings HT-FPV with a rubber isolated third deck inspired by the QAV 500. I really admire these two commercial designs and greatly respect the men behind them. It's still a work in progress as it was lost in weeds for a month this summer and underwent a large number of changes as part of the rebuild (no damage in the crash, but added lots of new stuff).

The frame is all wood with plywood decks and 1/2" poplar arms. It is reluctantly painted bright (and heavy) yellow to aid in recovery.

It's 570mm motor to motor shaft measured lengthwise, 730mm diagonally. It's a heavy bird now, likely more than 1.6kg TOW with 3S 4000mAh lipo. It uses GWS 3-blade 10x4.5 props, Sunnysky 2212-13 980kv motors and Simonk flashed RC Timer 30A ESCs. I get about 10 minutes of flight on a 3S 4000mAH lipo using 80% of the capacity.

It has a Naze32 v4 flight controller running baseflight, EagleTree v3 Logger and OSD Pro, ET v4 GPS shared between the OSD and FC, and RangeLink UHF rx. The video system includes a GoPro HD and Sony 600tvl pilot camera, an LC line filter, Immersion 600mW 5.8 vTx and Bluebeam cloverleaf antenna.

I'm still adjusting the parameters and am not yet satisfied with the way it`s. It`s really heavy and so isn`t snappy, but I want more smoothness. I`m also working on configuring the GPS with the Naze32 for position hold and RTH for emergency situations.

My other (first) FPV multi is an RC Explorer based tricopter. In my opionion, it flies much better than the quad, but that`s not a final verdict yet as there is lots of tuning left to try. It`s lighter, smoother and more natural feeling. Before I flew FPV multicopters, I flew R/C helicopters (for about 9 years). I've been building and flying FPV multicopters for about 2 years now.

Thanks, the delrin blocks have 2 fastener points located at diagonals. The outer fastener is the pivot. The inner is the removable "pin" which threads into upper block (wingnut attached to 4-40 machine screw - wing nut covered with rubber also acts as landing contact point - it can be seen as black "blob" under the block). The blocks were done with a chop miter saw and drill press. Access to a milling machine would improve the squareness and hole acuracy. The folding concept along with the "flatness" of the model allows it to be taken along in daypacks or hung outside a backpack.

Here's my wood frame quad. Looks kinda clunky, but it flies well, and transmits far less vibration from the motors to the center of the frame than my glass fiber hex. The controller is a Crius AIOP with GPS module wired to the board.
