I don't want to push my luck, but if there is any way to mount the gimbal in *front* of the face of the aircraft rather than inside the cavity, then that should still allow me to use my GoPro 3D system while still shrinking down the frame a bit.

This would be beyond cool. I imagine--since this aircraft is geared towards forest shots and such--that 3D will lead to some amazing footage flying through tree branches and what not.

On second thought, building in the 3D system may be better for a rev 2 design. It might also weigh too much for what we are attempting here.

Let's keep it simple. One GoPro nestled in there as you were doing.

Thanks!

Matt

Yes, it will be further in front. It was just placed there for size comparison.

PS: Wish I would have seen that cooked MWC Pro board you just sold!!! Would have grabbed that!!

Shoot--I would have just sent it to you. Well, now I know to send you anything that's fried.

Thanks,

Ill have some more ideas drawn out later tonight. Will post when I get something ready.

I have a really cool idea to replace the feet with. It will stiffen the arms more, and , make it very resilient to crash damage considering the inboard motors/props.

OK, made some changes.

Changed the shape of the motor region of the arms. The original would likely impede thrust a bit too much.

Changed landing skids that act as "ribs" for the arms, as well as top "ribs".

The top center plate will act as an accessory mount, and it acts as the locking mechanism for the "ribs"!!! There is a lower plate as well.

The skids/ribs also incorporate ESC mounts. If there is one thing I hate most about 99.9% of the current frames, is there is no good place to mount ESC's.....Just tape 'em / zip 'em to an arm.....pffffft!!!

Let me know what you think!!

Very nice! And I agree about the ESC mounting.

There is one small problem (but it is only a problem for me and I'll deal) and that is the Park 250 motors I will use won't be able to mount the way I have them configured unless I push the shaft to the other side of them UNLESS the bell housing can fit between the two slats that make up a rib. The diameter of the bell is about 7/8 inch wide so it may indeed fit in there.

In any case, no reason to change the design around a particular brand of motor!

GREAT WORK ERIC!!

I can make clearance for mounting them outboard of the arms. You would be better off flipping and shortening the shafts if you can. Shafts that long are going to be difficult to get the vibe out.

I looked for a drawing of that motor but could not find one. Can you take some measurements for me? Mounting plate/hole dimensions, overall length, diameter, and bell length.

Yeah--ha ha. In the photo I was to lazy to go get a hex wrench and loosen the grub screw so the prop adapter would sit all the way down. It actually does a great job when put on properly LOL!

Have you considered offsetting the top and bottom motors by 45degrees? Would that obstruct the camera or could the camera be low enough not to see the prop?

Can you measure the overall length with the prop and adapter installed, as you are going to be using it? I want to check the clearance between motors. Its enough, I just want to check a few things.
