Remember back, way back in autopilot years probably about 20. The year 2009 and the first round of our gentlemens (ladies are allowed just none have ever entered) competition the T3 challenge.

Back then just flying way points was hard and all this gear was expensive. Ardupilots were made at Sparkfun in batches that ran out quick.

Lets try it again I suspect this time the challenge would really be flying it faster than somebody FPV racing.

Read about the first time here for hints and tips. 

As tech has moved on all aircraft types welcome lets make it not above 50m and 5 laps. All of course autonomous. Extra marks if that is from take off to landing.I will count the time from take off to landing so screaming dives to the start will not help. KMLs as evidence please!

UPDATE: Rovers (and boats) are also allowed! There will be a special rover/boat class, and you only have to beat other vehicles in that class. The course for such ground/water vehicles is 100m x 100m. 

I will accept FPV times for the sake of science and should they be much much quicker it will give the pure FPV crowd something to brag about.

An Easystar (yes before HK copied it) made one lap in less than a minute in 2009 so 5 in 5 minutes should be more than possible. 

As ever the time frame is flexible but why don't we all meet back here on August the 1st and find out who won!

Please add your entries and adventures below. Points are always awarded for silliness, just as long as its safe!

Yes you would Stephan, the important thing to remember is that I make it up as I go along! In the past one entrant scored highly because they went out into the snow to enter a round. How nice to see so many original entrants chipping in. The amount of push for code change created by those that braved their platforms should not be underestimated. These brave folks have really helped make APM what it is today.

Yay! I'm totally doing that this weekend with Solo.

I guess the goal would be to catch up to manual F5D flights when it comes to speed and turn radius.

Its a pity you have to fly by yourself Chris oh no thats... I always thought F5D would be the perfect size for a race series of our own. We could copy that course next perhaps....

@JAB, that's nuts.  Are those like DLG's with motors?

Why do they have so much wing if they fly so fast?

These are the specs Rob

CLASS F5D - ELECTRIC POWERED PYLON RACING MODEL AIRCRAFT

Model Aircraft specifications:

  • Minimum weight ready to fly: 1’000 g
  • Maximum surface loading: 65 g/dm2
  • Battery Type: Lithium Polymer
  • Minimum weight of battery pack: 200 g
  • Maximum weight of battery pack: 400 g
  • Limitation of energy by an electronic limiter that stops the motor: max. 1'000 Watt-min

@Rob, it has to do with trying to get laminar flow and still have enough lift to fly and make the turns. Speed stalls during turns are also a common problem they have to account for.

And btw. the F3D class is even more extreme then F5D. They do the 4km (10 lap) track in down to 60 seconds.

I thought I might get the first entry in but sadly my IRIS had a traumatic encouter with a tree.  I didn't think they were 30m tall.. most weren't.. but one was.  Anyway, it's made a recovery and another attempt will come this weekend.

Any chance your copter is named George?

Blimey an entry within 24 hours that is point worthy in itself!
