she'll only be interested if I attach the aforementioned knife to the front so she can then disembowel me by remote instead. :sweating:

Got a little bit of time today, So had a ponder about how to mount parallel motors on the arms of the posible "Y copter" frame project.

Because one motor will obscure the screw holes of the other I was thinking about making the top mount as a piece of U shaped channel that bolts in through the sides. Then I thought that as "Soft mounting" was the in thing at present, I could make it slightly over sized and use rubber grommets in the motor mount to arm bolt holes....... Then it got a bit silly.

I started thinking that if I'm soft mounting the top motors, I really should do the same on the bottom ones too.

OK. What I've come up with is this.......



It would mean 3 bolt holes through the end of the arms and each mount having a tripod of mounting lugs so that each bolt holds both mounts. I'd put a rubber grommet and spacer tube in each of the mounts lugs to give the motor a little vibration damping.

The concept feels sound in my head, It's just the agro of a solution that'll need 6 quite fiddly little bit's making without me even having a bench vice anymore that's got me Oooing and Ahhing about whether it's a good solution. :(

Considering I could just mount one set of motors directly to the arms and make up flat plates with bolt tabs extending beyond the motor bodys to hold the other ones on, Am I ridiculously over thinking this?
Brushless = LT130, Outlaw 180, Q250, Q280, Q330, Q450 hex (On short arms, so it really should be a "Q350"), And a Q450 camera platform.
Brushed = E010, An E010 + Tiny F3 based "Tiny Whoop-a-like", QX80, QX90, Aggress Mini.
TX's = TGY i10, Modded FS-i6, And "iRX-i6X" (An FS-i6X in drag).

10p worth,why not make two separate motor mounts from GRP plate and screw the motors on with csk screws,this still allows soft mount. Then  bolt the two mounts with two bolts either end through the  arm.??

That was the pretty much the original idea, But as I have some alloy U channel sitting here that would fit over the arms with about enough room for grommets, I started getting creative.

Another thought was to drill 2 vertical holes through the arms, Fit suitable sized grommets in the 4 holes, cut down a pair of aluminium standoffs to 16 or 17mm, And fit them through the grommets with motor mounting plates screwed to them top and bottom. That would make a kind of floating mount that would allow a similar amounts of damping as the saddle mount idea, But I've got a feeling it would be a fair bit harder on the grommets due to the main force now going into the sides of the grommet because of the twisting caused by the ever changing rotor speeds ..... Though, Doing it this way I'd probabbly be able to get away with using those bolt on alloy "X mounts" that came with the motors. That would save quite a lot of fabrication work.  :hmm:

That certainly is creative, I know it's trendy to have damped mounts but a properly balanced motor and prop shoulden't cause problems. Remember K.I.S.S.  If it ain't fitted it can't go wrong.. :beer2:

Yeah, But who wan't to be simple? LOL !

Joking aside, I could go out and buy a stock Y6 frame from somewhere and get this in the air in a fraction of the time, But I like the idea of trying something different. If I tweak the build with ideas I find interesting along the way then I'll be a happy bunny.

As I've said before, I think I possibly enjoy the building more than the flying at the minute, So the idea of an intricate one off build isn't really that much of a negative to me.

I'm starting to think that the second idea of standoffs through grommeted arms could be better now though. The whole assembly would be easier to get right and probably a fair bit lighter.

I'm waiting for a few bit's and bobs to turn up for the DIY Y6 frame, And to be honest, I keep coming up with different ideas on how to best make the front arms foldable, So I don't want to start cutting metal until I've finalised the idea and had a play with some thick cardboard to check everything will fit OK.

As that frames gone back into the "Finalising the design" stage I found myself at a loose end this fine bank holiday weekend, So I had a dig through the "Stalled and half finished projects" pile and found the "Martian II" frame I'd built up and bolted Racerstar 2205 motors to. After another dig through the spares I also found a 20A Racerstar 4 in 1 ESC, An Omnibus F3, Diatone SP2 VTX, A FlySky X6B RX, Some random stackable PDB, And an Eachine 1000TVL camera that I've put a Foxeer 2.5mm IR blocked lens on.

I spent a happy 4 or 5 hours bolting all that together and ended up with this.....



I didn't want to stack the VTX with the ESC's as I had some impressive interference on a previous build doing that, So I had a think and realised that there was just enough room to fit the VTX and RX in their own little stack at the back.



Some of you may have noticed my strange routing of the motor wires in that second picture, There's a good reason for that. I started pondering about getting some "250" arms to go on this so it could run 6" props. If I do that I can just unbolt the stack from the bottom, Pull the wires out from under there and get a little over the required inch of extra wire back without having to break out the soldering iron to extend the motor wires........ See, I can occasionally put more than the bare minimum of thought into these things.  :laugh:

Anyway, Once I got it setup I chucked one of my 1500mAh Turnigy graphenes on it and took it outside. I buzzed it about in the garden for a couple of packs and it seems all good. In angle mode it's strangely stable considering it's still on factory PIDs. Also, for a 3s setup it's got quite an impressive amount of oomph when I mashed the throttle.

Now I just need to wait for a nice day to give it a proper maden.

It's a bit too windy around here to fly, So I decided to finally dig out the drill and see if the simple version of the "Damped motor mount cage" idea I was playing with for the Y6 build would actually work......



It's just a couple of the "X" mounts you get with most of the older motor designs, some standoffs, And some 5mm ID rubber grommets fitted into the 15mm alloy box section I'll be using for arms.

First problem (As is bloody obvious) was that I'd forgot that back when I ordered a big selection of standoffs, The only 20mm ones I could get had a hexagonal profile, So they won't work.  :embarrassed

As this is only a proof of concept at the minute I just used some of the 25mm ones I have instead. I've ordered a few 5mm x 20mm M3 standoffs to replace these. The grommets are 6mm top to bottom with a 1mm "slot" around the middle, So with 2.5mm protruding top and bottom out of a 15mm box section 20mm should be spot on. Worst case I'll need to shave a mill or so off each to give the grommets a little preload, but that's no biggy.

It feels quite a feasible and simple way to mount opposing motors as it stands, With lots of resistance to being twisted, But still having a little give if forced hard. The standoffs will ensure that the motors can't flex independently, And I think with a few different hight washer stacks between each standoff and the X mount I could have a quick and dirty way to tinker with thrust angles. I've always wanted to try this to see how much giving the props a little dihedral related to each other (Thrust lines converging to a point ABOVE the multirotor's centre ) effects stability.

Anyway, I'm starting to feel ill so I better leave it there.

Rotorx atom again!i had to repair the top plate (regardesvous the lollipop sticks) epoxied the mount holes as it did nose dive.

Rebuilt with a holybro kakute v1 aio,the dtfc hax a twitch i think and i want this quad stable as its realy fast when its running.its missing fpv gear at mo cos i cant hot glue the cam in as i am waiting on new hot glue gun.

But its kinda my fav!

Something to aim for.

How are you finding those props?

I found they were a bit too heavy, speed pickup and top speed seamed slower, also a bit less stable, more prop wash and bounce back.


WOOOOH   :o just read the static thrust of those motors and 4045BN 2 blade props. warnings.
So with tri-blades you are really over doing it. Good luck :evil lets us know how it goes.

Pulls about 70a on the tris on climb out, yes its on the limit but flew nice, and yes the props are heavy, trying some gemfan 4045 bi props atm they do seem snappier but less punchy, thinking of trying the dal tj 4x4.5x3 to see what they are like.
