WHY?

- I got tired to constantly change propellers

- I got tired from being scared to hurt somebody

- I got tired not being able to fly inside of the house without damaging furniture.


A BIT OF PRE-HISTORY

As many of you, I've started from 250mm quadcopters, just because it was the smallest quadcopter you were able to get at some point. I quickly realized that it is not what I needed, because it was not really small, it was scary dangerous for surrounding. Well forgive me, but I can't drive outside of the town too often to fly this strong and scary machine and in the area where I live, kids are playing everywhere. At home, with my level of flying skills, you will either break everything around or cut somebody's head off. So I've got prop protectors for it, but whoever designed them didn't realize that you will need to protect propeller from top and bottom, because otherwise it won't really have the effect you need. So my experiment has failed and this quadcopter was mostly collecting dust on the shelf.

Then I came across 1104 motors and 122mm micro frame and immediately thought that this is what I need! To my quick disappointment I was buying hundreds of propellers every month, so not environment and wallet friend, and frankly annoying.

Then I came across 90mm frame with dp03 7800kv motors and loved it (still love) so much, I thought that this is probably what I was looking for. But unfortunately it missed some of the qualities which my 122mm quadcopter had as for example you can't fly with GoPro camera, it has relatively weak throttle response on 2S batteries (it is way better on 3S batteries) in comparison to what I've got used to, inability to use cheap and good motors on it.

It made me think that it would be great to have something like this but for more common, as of now, 3 inch propellers standard. I've asked around and nobody was offering any solution at this time.

I've figured that I'll have to design something by myself It took me some time to refresh my AutoCAD skills.

While I was figuring it all out, new frame with the name "Butters" appeared and I thought oh, great, now I can just buy and use it instead, but then, after I saw if for the first time, I quickly realized that it won't work for me as it didn't provide enough of mounting flexibility for quadcopter equipment and looked super heavy.

Well... I guessed, that I would actually have to try make something myself then. After all, this hobby is about research and development

Novice question,cool design, what would that cost to build and could it be done with motors that have plugs instead of soldering, i cant do soldering, i'd love to do a project like this.

Looks nice, and the flight vid was pretty extra ordinary to me. Plans to sell frame kits?

So when can we order a kit?

Subbed! Was looking to build the butters but may end up building this instead. What exactly are the differences aside from the obvious no deadcat and pusher props?

Enjoying every minute of it...

What Brian said. I'm looking for an RS90 but with bigger balls for outside and not worry about torching the poor little DP03 motors.. Try 4s yet on it?

I think it looks nice too. Looks like the larger layout allows for a standard 35mmx35mm stack. Also good use of the diatone camera mount. I wish they'd hurry up and release a 100 degree fov version of that camera though. That 170 lens really isn't the best for fast proximity flying.

I've updated post. Weight of both plates together is 55g. Hardware is another ~18g and nylon is much lighter

Cost to build will depend on how much person charges for his service. I like the idea of solder-less assembly but I'm unaware about parts like this. If more people need plug and play parts then we can try to figure something out.

I have a few extra plates, which I can sell, if anybody is interested, but price will be probably higher than mass production. If more than one or two people will be interested then I can try to work out a cheaper price or use Armattan production, but I will have to learn about them more first.

Main difference is mounting options, you can use all kinds of VTX, Camera holder with adjustable angle, many holes to keep wires organized. Also weight should be at least 20 grams lower.

I've tried it on 4s it was too fast for me to handle, but great with GoPro.
Actually I was able to fly quite well on 3s with GoPro without battery on RCX 1105 motors, but with GoPro battery it was not flying too good.
