Micro Stealth FPV


#61

Not good at detailing this lol.
Place the quad on a level surface. Go eye level with the propellers ( make sure props can not engage of course) and spin one at a time with a finger. As the prop is spinning you will be able to see if the blades are bending down too far or even up extending out from the hub. I bend mine down a bit lower than horizon level (theory) so when a lot of throttle is applied, they do not flex up too high. On a low budget here still and learning a lot of small tricks to keep flying. Just as every gram counts on a micro, every bit of vibration/ off balance parts eliminated makes a huge flying difference…

@user179 without lipo it sits at 45g. I use 3 different size batteries and have a timer set on my Transmitter of 4:30 I rarely go over it even if I’m having a great flight :slight_smile: so that’s my time on it. I run mylipo 480mah & 700mah, and Graphene 600mah.

I measured the frame’s FC compartment from inner standoff conservatively and it will fit 30mm x 30mm board with no issues , but I will include the frame’s designer @jayson in hopes he can say if the Beef’s Brushed Board (32mm x 32mm) will fit. I know for sure it would fit the width .

@user179 my recent experience in brushless has shed a lot of light into exactly what you are trying to achieve with your requirements. My opinion is that brushed is extremely limited by weight, especially heading into fpv setups and extras (Excluding LOS).

Hi, i think the beef should be fit. But the Frame is specially for the Scisky/Quanum, because they are only 30x20mm. The beef will fit, but stick out a bit on both sides, because of the 32mm. But i think it will work fine. The little cleats for rubber bands measure 30mm from side to side.

@MasterRC_sTudenT you have done it very well :slight_smile:

@quadflop : Thanks for your infos ! it is not easy to balance these props…
Well I have put some dental floss on my props though… It works much better and for now no pop out !!!
I made a video from my personal experience to insert the dental floss on props => Micro quad FPV : How to fit props with dental floss

Ladies and Gentleman(yes,it’s been confirmed),
I would like to present my Micro Stealth FPV.

First, thanks to @jayson for his design; @t_schoepper for the CF version; @giles for the mulitflite Pico FC, and @Benedikt for the 8.5mm MMW motors.

I tried out parrots and a crazy FPV angle to which I quickly modified to its current configuration with Afuenta clears.

I have not flown w the HV’s as its maiden flight was w mylipo 480’s. This afternoon I plan on ripping the skies wide open w this quad!

Very nice build :smiley:
Are you sure the motors are from us?
Ours dont have holes in the top…


#67

Shit!
Well then I’m not as mad at my Nephew for wasting them. He’s seven. There’s yours😅 Mixed them up.
Btw, that frame can take a beating


#68

Yes, its a nice frame. I have one too :wink:

Little myth busting on the side:
It was told that the holes on the motors are for cooling. They are not. They were closed before running the motor in their original application. They are intended for mounting and have no significant effect on motor temperatures.


#69

@Kamsleo69 nice build !

I appreciate your idea of the motor mount. it is not the traditional way of mount and it is good point to have 4 real feet made by heatshrink. I was wondering if the nylon screw are strong enought for you ? Because I have this frame and these nylon screws often boke in the field after crashes… So I prefered to use some new steel screw unbreakable but 4 times more heavier !! damned…!

About the camera cover it is brilliant idea ! I am waiting for your crashes feedback to be sure the glue is enougth to maintain all correctly.

Please give us your total weight with and without lipo

That’s funny; any excuse to leave things the way they are!
It makes sense when you think about how these motors were used in applications before micro-quads surfaced. How else would they be mounted in medical tools without screw holes in the tops! Looks like MMW sells the only coreless motor built specifically around micro-quads.
Plus, holes let dirt and dust in motors. I went to a 4 story house under renovations to get some awesome flight vid and didn’t last 1 min before the dust killed my motors.


#71

Thanks @nico2nice
The nylon hardware I’ve found to be single use only, so I have a kit around 200pc found on Amazon. Since I only use them once, I add a drop of CA to thread protrusion after tightening to secure.

My thoughts on the strength of the hardware is I would like those to fail in a crash rather than the frame. Easier and cheaper to replace.

I will attest to the CF camera plate. My nephew rolled her across the ground many times. Granted, she hasn’t gone in head first at speed, but then I expect more to fail in that scenario than a camera cover!

I will report back AUW this evening. Here’s the HV500:


#72

NOOOOOOO!!..
Damn the rain
No HV testing after work😡


#73

Hi !!!
Is it rainy day today ? :sunglasses:


#74


#75

lol !!! You will fly indoor then because it is raining until this week end :joy:


#76

You are not alone on that map my friend. We’ll get through this together!


#77

Thank goodness for brushed micros to fly indoors! :slight_smile:

These torrential rains make me wonder whether Noah had micro quads to pass time on his ark. :wink:


#78

Hi, here is my last video with magic smoke at the end. :wink: Time to tinker…


#79

Bummer on the magic smoke… Pretty cool to catch it on video though. That looks like a fun place to fly…


#80

yes, i thought that, too… :slight_smile: That’s my garden and is perfect for the micro copter to fly. There are many possible rounds…
