M4 Quad 300

[chschmid]

Here a new build prepared for the KISS ESC.

M4
Joergs expansion board
MN2206-2000
KISS ESC

The goal was a frame where I can assemble the quad with the frame "open". When everything is at its place, the frame can be "closed".

Cheers

Hi Christof, that looks very nice! Stiff and probably hard to break. How do you keep the top part attached? Also how do you connect the GPS antenna? I was just thinking earlier today about a "quick release" system for the top plate, for easy access to the FC board.

I'd like to see the sides glowing blue like in the render, please...

Cheers,

Hi Christof,
NICE ONE! Would you mind to mill ONE more?

I'm using These M4 with a 25mm GPS antenna atm with excellent results and plan Top use a 35mm on the 250size Quad.

So'nt think you will need the GPS hood. Makes connecting the GPS antenna realy hard.

Hi Christof,

It really looks good and should be nice and rigid. The rigid frame may be worth the weight penalty.

I really like the board Joergs has done and the idea of plugging the M4 into it. The M4 has generated lots of different ways to use it.

I did a drawing similar to that for a 250 but decided to not cut it. I bought a HK FPV250 frame instead which is pretty much indestructible. I am going to make a H configuration that will be much lighter but will not be indestructible.

Todays maiden was successful. I used the RPM2Thrust curve based on scaled PWM input. No PWM preload. Standard 432 repo code with quatos. AUW 520Gr with a 2250 3s battery.
The result was good, but I only had a short flight as it was almost dark.

Cheers

That looks really nice, I'll bet you could use thinner carbon sheet on the sheer webs and the top plate to save a little weight. I like it much better than my FPV250 from HK but at least it was cheaper. I've only used one other commercial frame and that was from Rusty.

This is Kiss Esc Emax 1806 with 5x4 HQ props Quatos R432, I am using the pre-load with reduced preload values. It's got BT, 5.8 video link with MinumOsd and camera tilt. Since the risk is so low I find I fly it a lot with a remote 5.8 receiver and a outdoor Spektrum antenna.

I consider it very heavy at 500 grams but fly's at a throttle factor of .5.
