Sounds good to me.

Definitely 2.5mm.

Alright I changed up the 2" toothpick arm design to match the 2.5" and added the 9mm 4 hole spacing. 

I also slotted the original 3 hole pattern to accept 6.6-8mm. I was going to match it to the arms on the 4 hole pattern, but kinda needed to keep the arms that style because that shape works better with 3 hole pattern. Ideally motor mfg's would just use a dang standard! LOL 

   

Hi Lukeman,

Looking good, Mate !  

I am going to want one of each; plus the two already in production.

Later, iFly 

Ok Lemmy,

I think I've got a good compromise here for ya. I can make you a version that does both 4 hole and 3 hole mounting. I added the M2x8 3 hole pattern for those emax motors.



I need your guys' feedback. I don't really have a canopy design for either of these. I was going to just sell the carbon and hardware with these. Then you can print/buy the canopy of your preference? Does that work? Or is there some value to have a 3d printed canopy included in the kits?

   

That is awesome.

Personally, I can print my own canopies, but not everyone can. It wouldn’t hurt to have an option to purchase a 3d printed canopy- but that can get complicated with different camera sizes and mounting requirements.

Hi Lukeman,

Personally, I think the canopy should be sold separately if at all;
maybe the hardware as well. You could have the bottom frame plates
separated from the other stuff. Maybe offer hardware as an optional
accessories package. 

First, there are tons of canopies that will fit the 25.5 x 25.5 whoop mounting pattern.
Yeah, some better than others and different ones for different stack or camera setups.

Google = Whoop Canopy

I don't need a canopy. First, I already have tons of canopies that would fit.
Plus, I will likely just make a top deck plate from LEXAN plastic or make my own
custom camera mount or canopy. 

I also have thin sheets of brass, copper, fiberglass, and aluminum in addition to LEXAN 
and assorted other plastics. Yep, I save plastic from blister packs and bottles that 
stuff comes in; this is free and quite workable. 

By the way, my standard camera mount is a set of aluminum cam braces from an
Armattan Tadpole which are 20mm. Yeah, you can buy them separately and they
work just fine to replace the front two standoff columns. They look kind of "trick"
as well. I like them. I also have cam mounts from the Roma F1 and other BNF
quads. Most of them are 20mm, but there are a few that are different.

Regarding hardware, I pretty much always use stainless steel bolts and nuts on my 
builds. The FC bolts are always thru bolts that extend from the bottom plate up as
high as I need for the application. I don't feel the need for titanium. I don't use
aluminum or nylon bolts or nuts. 


If I have a bottom plate, I have a build.

Looks great!

Hi Lukeman,

WOW 

I Like it. 
I can envision several different type of builds.

I started tapping out and running bottom up bolts up through the side mount holes on the Whoop frames to bolt down my canopy & keep everything snug & in place, and a lot more solid than those tiny little screws that thread into plastic. Plus I can layer in a vTx & mount it to the side bolts with some rubber grommets & give it good air flow above the f/c & keep the vTx good and locked down too.

I checked out your list . . . good to see you're not addicted to building these things either, although size wise, you could probably fit most of mine on the backs of a couple of yours . . . you sure do like the big guys . . . It's anything but . . . but . . . I could understand you calling an 85 a "Tiny" Whoop . . . compared to your fleet, you could carry one on the back of one of yours for a spare! Oh . . . I can quit building quads any time if I want to, I just have a few more to build, so I'm just not quite ready yet . . . or was it I have a few more ready and more to build . . . or something like that . . . anyway, if I wanted . . . 8^}

Helluva an impressive fleet you've built there . . .

Hi Brian,

Thanks. 

You know, I started with tiny whoops, then sort of worked my way up that ladder.
The first time that I flew a tiny whoop (65mm frame, 31mm props, brushed motors) 
outside, I quickly realized that it couldn't fight the wind. So, I built larger brushed
motor whoops; up to 85mm. Next, I move to open prop "toothpick" frames with
all the guts of a tiny whoop including the brushed motors. As I increased the 
prop size, I came to realize that 3 inch props just didn't seem to work and that
55mm was about as large as I could go and still have stability. Yeah, the FCs were
NOT programable so NO tuning or tweaking. Move on up to 2.5 inch open prop
freestyle quads with brushless motors, programmable FCs, and a "Real" transmitter.

Brushed motor BNF quads:  

BetaFPV Meteor 65S
EMAX TinyHawk Freestyle (original)
GEPRC Phantom analog (original), I lost the first one and bought another.
Flywoo XBOT3. After 3 flights, the electronics went out and just be sitting there.
Darwin Baby Ape (3 inch). Not yet flown, needs receiver, just waiting. 

Even as I moved into the brushless quad world, my focus has always been on 
keeping the quad's All Up Weight below 250 grams (FAA category 1) in order to
fly under the Recreational Exemption. All of my 5 inch and smaller builds are
actually sub 250 gram builds. Plus, all of my BNF quads are sub 250 gram.

I was actually working towards a long distance flight to get a 5K badge. As I learned 
more about the legal issues and everything sort of started hitting the fan, I abandoned 
that idea. 

The 7 inch Rescue quad build is the only one that exceeds the 250 gram weight limit.
This quad was built for a specific, one time, purpose. However, the window of opportunity
passed before I could get it fully functional, so now it is essentially a wall ornament. This
build started with a 6 inch frame. Notice the motor staggering in order to run 7 inch props.
Also, custom fabricated plates. 

You might have noticed that many of my builds have some personal touches.

Here are a few pictures of my brushed motor fleet:

Due to my house building project taking up most of my time, the FPV hobby is sort of 
on hold except for trying to keep up with this forum a little bit.

Mine didn't look that neat and clean when I took the pieces outta the package.

I kinda started the other way, had a bunch of open prop brushed, the Hubsan H107 & cousins, a really kool Holy Stone Bolt Bee that's still fun to fly around, and a couple of the bigger plastic 2S Hubsans & a couple WLToys V686Gs, along with my little Whoops, a Furibee & a JJRC, and then, my B03.  I came across the B03 Silverware thread on rcg, and the build it yourself guys, & especially Nigel Sheffield, who gave me a ton of guidance & help, and was the biggest influence on me to start putting my own (Whoops) together. 

I was going to break down & sacrifice a B03 board to flash the Silverware on it, right when the Beta & Beecore/Silverware boards came out, so I saved my B03 boards and bought a bunch of the Beecore/Silverware boards instead. I made pairs with the same frames, motors in 65, 75 & 85 with the Boldclash "Hot" 716s, and KK 820s & 8520s for the big guys . . . That really got me started with the Whoops, and that fall was when the new brushless Mobula came out . . . and that setup for a brushless was like Whoop Crack . . . it made it soooo easy to setup a brushless Whoop, and they were so superior to the brushed . . . 

I still have a box of LOS brushed 65s & a couple bigger, in my brushed LOS group. I do fly my original brushed B03 & it's Beecore clone in the house quite a bit along with the little brushless, and are still a lotta fun to whoop around with them.

Never really liked the big size quads and how they felt flying. Maybe it was the toy radios along with the very bland settings on their f/cs, plus brushed power vs brushless, but even my 152mm Dolphin is pushing it, and about as big as I'm comfortable flying.

Alright guys I have completed this new 2" frame. I'm calling it the Pixie. Just finished a pair of each style frame. One has 3 hole pattern and the other has 4 hole pattern.

The 2.5" will be on the website in the next couple of days. Had to get more Jitterbug frames done along with these new Pixie frames. Stay tuned for more!

I am just waiting for that 2.5 inch frame.
