In HellYea's thread , SMJ proposed FPV racing for multi's.

After a bit of a discussion we came up with this as a trial

20 meter/ 66 ft course (same as a cricket pitch, netball courts are 25 meters)

FPV or onboard vid to record the action

5 laps, figure 8

So, today I had a practice, i thought 5 lap, pffftt , easy....after 3 laps i was wondering when it was all going to end !

you really need to get the turns coordinated roll/yaw/pitch/throttle all at the same time
Im flying visually, and my CCW turns on my right are OK, but my CW turns on my left, i almost seem to "stall" as i forget to keep nose down pitch - practice practice.....

Posted a video as below , as all my flights end with a crash, i have put that at the start (so you dont have to be bored by my flying)

Using the "sitboy" Vtail - where the props are angled 30 deg forward pitch, so when flying with the camera level, its the same as a normal quad pitched forward at 30 deg - looking at the vid footage, it shouldnt be to hard to learn to fly FPV like that.

Where are the pylons?

Go Matt Go ; you give us a good starting time to try to better.
i went out in the yard & marked out 20 meters. my first flight was a fast oval, or just a 20 meter circle.
now have another camera , will have to try figure 8's
the weight of the craft is going to make a big difference.
IE; a fully loaded FPV set up , or just the basics.

using the artificial grass cricket pitch (you can see it in the photo), its about 22 meters long, dont have any pylons as such chose the 66 ft/20 meter length as should be easy for most to set something up.

its worked out great ( IMHO ) as you are always turning, so speed isnt everything


@timbocan - good that you are giving it a go my FPV gear (inc OSD/GPS/Current monitor weighs 200 grams ! same as the gopro , so swapping one with the other will be the go. My multi is overly heavy (lots of thick aluminium construction) needs to be lightened

haha, looks like fun. Drag racing next?

oh yeah, forgot about that

[Mat Wellington]

haha, drag racing, man thats old news (like...yesterday !)

for you experianced FPV guys we expect a barrel roll in the middle of the figure 8

Very cool Mat! I was watching a fixed wing pylon race the other day and all I could think is how much cooler it would be with multi rotors and FPV, it got me thinking.
Flying with goggles is the way to go IMO! Freakin cool! And I also think starting the race with the multi rotors on the ground would be bomb!! Picture it... "3-2-1" and then the wine of half a dozen quads taking off for the first pylon.
The figure 8 pattern didn't even cross my mind but think its a very cool idea. I'm gonna try the mesurments you suggested in the next few days and see what's up. Thanks for posting!!

Haha that's very good!

i think we would have to come up with a set size motor center to motor center and maby prop size (not pitch) and maby AUW as well for both drag and pylon

[timbocan]

Haha ; no flips from me just yet. still flying attitude settings. still seeing how much wind i can handle , with out it trying to self level.
i've managed to have my fun crash quad; siting at 45deg in one spot holding into the wind.
and boy it takes off down wind when blowing 20 to 30 knots.

eventualy........but keep it simple for now.... fly what ya brung im not sure that bucketloads more power will beat a better pilot

[thefokker]

Im in!!! Ill setup a course at my super secret fpv base and post my results. It may be a few weeks before I can get out again. Great idea. I was wanting ro do some sort of racing. Ill also do a nice low flip on the last lap lol!

[Terrier]

I'm still waiting for parts before I'm gonna try it FPV... 4S batteries and a voltage regulator.

I've been practicing LOS for now. Waiting for the glue to dry before I hack at it again!

[Mat Wellington]

well everyone, i expect to see some vids soon from your attempts - remember it dosent have to be FPV, just get it on video

[scottevil]

i have to do the pylons at the field i fly at.. everytime i go i kind of forget, or chicken out..

[HelliYea]

Awesome work Mat - once the weather clears up I'll give it a go

[Terrier]

Went out back of the camp and set up my 66' course of fire... gave it a shot a few times LOS, but the wind was just too much. Kept spinning on the yaw from the wind, and I couldn't keep it together.

If I ever make a 5 lap circuit, I'll include all the crashes caught on my headmounted GoPro in the victorious video. I think my "course time" is going to end up in the "several minutes" range if I ever expect to hit five laps without a crash.
