Quadcopter Science Project

Hi I am glad you found this out show you did the job right , bigger props need a low KV motor this also has more torque to spin the prop up to speed on throttle changes , And yes you are right the quad will fly different on the larger props low kv motor ,this is why racing quads use small props and 2300kv motors real screamers

I thought I would follow up a bit on this. We added a FatShark v3 teleporter FPV system to the quad. It has taken a few flights to start to get the hang of it, but it is really a lot of fun once you get the hang of it. It is also good for letting friends who don't fly "go for a ride".

Below is one of the early flights. A bit rough at first, but fortunately this quad build is quite durable.

Haha, yes FPV is sure something to get used to.

Well done Guys I loved the video keep up the great work

A couple of short videos showing the quad in action.

Meet the quad:
The "eye" on the front was repurposed from an old LED desk lamp. It is really bright, super light, and doesn't draw a bunch of juice. It is very visible even in bright light and makes orienting the quad very easy.

Looking great, the eye looks like it would help a lot.

Hi Nice quad you fly it nice , I watch the first video a few times I dont know if its the feet that wobble or if its the quad , if it is the quad you need to lower the I gain by about 5 points on the pitch and roll axis this will stop the wobble and make it smooth , well done

Holtneil, In the video it is the feet wobbling. There is just a bolt with washers holding on each of the feet, so they do wobble. But we have had issues with the whole quad wobbling, so it is good to know about the gain. I flashed the bios to the v1.6++ AiO firmware by RC911, and the quad seemed pretty stable from then on. I would also like to try the newest steveis firmware to see if that is better. My son gets irritated with me when I start messing with stuff, though.

For anyone thinking about this kind of build, I will say that the flamewheel frame is pretty durable. We have crashed it into trees, walls, the yard, and the street, and usually we just have a couple of props to replace. This really was a good choice for use to learn to fly and make the jump to FPV. Good times!

The flame wheel is a tough frame great for newbies go for steveis1.8s1pro it will fly well on default setting

Here is the new camera mount I built for our FatShark camera. Works very well and costs almost nothing. Camera is a bit beaten up from all of the FPV learning, but still works pretty well

Haha, looks good, you probably could get by with the bar in the front only going from aluminium to aluminium. Maybe just rivet them together

Thought about rivets after, but didn't leave myself much overlap. Out of rivets as well
Very solid like it is, though. No vibrations.

Probably rivets on Camera_mount 2.0, though...
The aluminum I am using is pretty thin an light, and that cross bar makes that frame even tougher.
When we get better at flying, I will probably try to build something lighter and faster, but for now durability is really great.

Haha, you should see mine, aluminium channel with wood inserts, and has corner braces. Only 370mm, but weighs a little over 3ibs
