The Chameleon arms look stiffer than the Reverb to me. I have 2507’s on my Reverb and they are about perfect, no signs of over torque on the arms. Anything bigger might cause some flexing issues, so the Chameleon sounds like a better choice.

I am gonna cross my fingers and hope for the best. If the motors do not work on the chameleon I will put them on something else.

I feel you will be fine with the larger motor sizing on your Chameleon frame than the Reverb frame. Your choice is solid and the Chameleon arms are part of a solid bottom plate, they should be more rigid to handle the extra torque without flexing. Really looking forward to hearing your experiences with your build! What FC are you considering?

I started doing a build series. I stoped to have a discussion about the frame. Here’s what’s I’ve gotten in so far. I will solder in the motors next. I’m having some dilemma about where to mount the gos and vtx. There’s no mounting holes on the vtx. There are 4 screws that hold the 2 boards together.

Hi Kevin,

GPS mount made with plastic from old bottle; Picture HERE.  
Cut the plastic, drill holes, use heat shrink tubing to secure the GPS, bolt to the frame.

As for mounting the GPS, I have seen zip ties used; you might also use stick on Velcro or the blue sticky tack stuff.

That’s a great idea and very light weight! I could use a green bottle to match the color scheme. Did you heat shrink the gps to the plastic? It’s a little hard to see in the picture.

Hi Kevin,

Yes. I used a piece of clear heat shrink tubing {I think is about 3/4 inch ?}, slide it over the GPS and plastic, then shrink it with heat gun. The plastic that I used just happens to be from an MCT oil container, but you can use anything and any color as long as it is a decent thickness so the tubing shrinks before the plastic hits critical melt point. 

Everything we buy seems to come is a plastic container, so I cut up anything I think I can use and keep in box. In addition to containers, almost everything comes in some type of plastic...some thicker than others, but each has a use. I got a new case for my cell phone and the plastic it was boxed with is flat, pretty solid, and light weight...Yeah, I kept that.

Regarding the VTX: I do not heat shrink the VTX because of the heat generated. I have used the heavy duty Velcro or zip ties. I think the sticky tack putty stuff might also be good, I intend to use some on something just to test it.

I ordered some 2mm screws and 2mm standoff kit. I can take the unity’s screws out and put longer ones in and thread stand-offs on. Then I’ll bolt the whole thing down. Yeah I’ve never heat shrinked a vtx either.
