General Multirotor FPV Thread
Created this thread for all General Multirotor based FPV discussion. All of the general FPV multirotor stuff was previously dumped into another thread that was becoming a catch-all and really had nothing to do with the original content of the thread (Sorry Al

So post up. Questions, videos, this part is great, this part is in stock again, whatever.

Phillips942 - You, like several others, have taken the Hoverthings landing gear off. Is this to reduce drag, lighten up the AUW, fly through small apertures, or all of the above?

I've been keeping the landing gear on so that I can suspend my GoPro underneath and keep the props out of my video, but my flight times seem a bit short and may need to reduce weight. I'm also flying the GoPro inside the protective housing, but I do have a LayerLens if I want to shed the weight.

I should have my 1.3 GHz FPV setup from RMRC next week and then it will be going on one of Tom's FPV frames too with a full Ardupilot setup. Deciding whether to go with goggles or just a screen for now. It will be a long slow go at it anyway....

Kjon12,

You are right about all of them but for me it's mostly to shrink the overall profile of the quad allowing maneuvering through tight spaces if necessary.

If flying FPV its hard to tell how low your landing gear is if you are flying low (Nap of Earth) style flying. That is one time I would not want anything slung lower than my camera that I cannot see.

I need to buy a digital scale so I can see how significant a weight loss or gain my Quad goes through when I add or trim stuff off.

What quad are you flying? That GoPro case does add a good amount of unnecessary weight to your system, I'd recommend you put that layer lens on. It will save you weight and flight time.

I agree completely on all points, especially keeping with the low profile. With the FPV cam on the lowest part of the frame, you can get in real personal with the ground(or water) in flight.

The "pad" style landing gear is far less prone to breaking in a crash than the stock legs. I also feel that landing is allot easier as you do not have to worry if you are drifting slightly and having a leg catch in the turf, running landings are actually possible.

+1 Absolutely agree with all points. Al was there when I busted the legs off during FPV a week or so ago that I would not have busted off LOS. It was a triggered failsafe because my camera hit a thistle and I lost video. If I would not have had the legs on it would not likely have snapped two of them off and may have just tumbled a bit.

I have a Hoverthings 450 and a DJI Flame 450, both with a Naza controller. I've been using the H.T. 450 for FPV because it has tabs on all 4 sides for mounting things, and I've been mounting my GoPro via a tripod mount under the bottom front plate, and using the legs as a buffer to keep the camera off the ground. With this setup, there's no props in the GoPro video.

The DJI Flame 450, when set up stock like the guy did that I bought mine from, the only mounting tabs are on the sides, not front and back. The only way I can mount the GoPro is on top of the battery. This works, but it exposes the camera if I happen to flip upside down or fly under a tree limb or something.

@ Dave Willis - The DJI Flame 450 is really smooth and fast...it's got 9" 3 bladed props, and isn't carrying all of the camera gear. It's fun to fly and makes cool sounds in the air as you whip around. It can be hard to see the orientation, though, but I think that's a problem with all quads unless you have something specially mounted to help with orientation.

The VC-450 from Hoverthings is not as nimble, but I've really loaded it down with camera gear. I think if I removed the cameras and the landing gear, it would be comparable to the DJI Flame. However, it does have smaller motors and can't run on 4S, something the DJI Flame can do.

As built, stock, the DJI Flame doesn't have much for mounting options for extra gear. The two tabs that are there are perpendicular to the direction of flight, so mounting a camera facing forward takes some ingenuity.

Just rotate the FC 90 degrees, swap props, reverse motors, and remap the ESC signal wires accordingly. Tabs will now be oriented fore and aft.

FPV question
Ok, I have a question. I installed my camera fixed forward and with about 25 or so degrees down. In my goggles field of view you can't see any of the quad, I tried to fly it but I could barely get it off the ground... Question is do I need to mount that camera so that I have some sort of reference between the aircraft and the ground? Or do I just need that much more practice. Thanks

Why couldn't you get it off the ground? Is the model to heavy for the motors to lift it or are you just nervous about the leaving the ground on goggles? I dont know about others but i use the horizon as a reference if i cannot see any part of my model in the field of view.

Why did you tilt your camera 25 degrees down? That seems like a crash waiting to happen. When you are in a hover you will wonder why your model is flying backwards when you see a level horizon in your goggles. The trick is to fly the model as if you were inside it (so to speak) so if the model is straight and level that is exactly what you should see in your video feedback.

Lastly yes i would say you need more practice. There's no better teacher than you going out and trying your experiment and making tweaks and adjustments as you go.

If you have a TV you can setup in place of the goggles, you can have someone call level when you are flying your quad LOS in a hover to adjust your camera angle. If the models in a stable stationary hover you should see a level horizon on your TV screen.

Hope this helped!

Keep in mind, like you said remove the cameras and such and it's much different.

A) That frame is as nimble as you make it. Without my camera and FPV stuff on my VC450's I can link multiple flips and rolls together without issue. Also you must consider your flight controller. If you're using a DJI Naza you're not likely going to have a very nimble feel to it no matter what frame it's on. If you're using the Quadrino they (Hoverthings) sells, you can jack the settings up on it via the multiwii gui and you'll be tossing it around like it's a toy.

B) You can put whatever motors you want on that frame and use 4s if you like.

hmm
Just reading this kind of interested in a quad. I have read alot on the flamewheel and the VC450.. I have all the downlink stuff already, but it seems and I am an exrteme newbie to FPV if I purchased one, but it seems that lots of guys setup the system to be too agressive on inputs as though they are going for a tick tock 3d setup. Is the bouncy ness and fast inputs say left right the nature of a 450 class quad for FPV or are a lot of guys dont understand expo and setup? I am guessing the prop loading and prop size in the esc can deflate the rigid movements the cameras show. I guess if I where doing video or my humble view is smooth and gracefull setup beats anything and any display of FPV.

I saw one really good video a guy did on a 450 a while back and it was really smooth, but dont remember the link on youtube.

Looking for some comments on this. regardless of FPV or video nature on a 450 class.

Believe it or not the DJI Naza FC is very mild in its control behavior. If you take a look at the DJI website for the Naza unit you will see that the Naza was not meant for 3D flight but very stable controled quad type flight.U.S. Navy [Avant Aurora/2 Trex 700N/600NSP/450Pro]

I have a VC550 with CCB and it flies great, I'm not nervous just trying to get to a hover without drifting 10 or so feet from the starting point.
Why did you tilt your camera 25 degrees down?
I gave it a downward tilt to help see the ground... obviously that's incorrect? This is all new to me lol
If you have a TV you can setup in place of the goggles
I have it linked to my laptop to record I'll try to fly from there.

Thanks for the info, I'll make a few adjustments and leave some feed back.

I agree with you guys regarding speed, power, and "nimbleness"...it's all relative and related to what you're really trying to do. With my VC450 and camera gear, I'm going for slow and steady in order to get good video recordings. Switching to an airframe without the camera gear is quite a bit faster, but not necessarily to the point where you start flipping around and doing stunts. At the moment, both of my airframes have Nazas, so they won't be as quick as something with a different controller, like a CC or MultiWii.

I've been playing with the Gaui 330 model on the RealFlight 6 simulator...it seems fairly realistic to me. Do you guys agree? I've been playing with flips and rolls on it, and I get through them about a quarter of the time.
