Thanks for the pictures and the link to BPLR's site. By the way, is that your 19.5" APC prop????

Great slide show on UTube. Now I not only want to fly there, I really want to have lunch. How come our contests aren't catered like that?

Awesome pictures.
I've been so used to seeing Gernot flying IMAC-type stuff that it's interesting to see him at an F3A contest, flying a Yak no less!
What's BPLR flying, Axiome or Osmose?

1bwana1,
I say that you should set the precedent at the Miramar contest next year. I saw a thread from an argentinian contest a while back that looked great as well, good wine and big steaks (after the flying of course).

In a Spanish forum I read that Gernot Bruckmann`s YAK 55set up was with an AXI 5320 and 6 Li-Po configuration. Does anybody know if this is true ?

I meant that he uses 6 Li-Po packs instead of 10 Li-Po packs for feed the motor. If you see carefully the nose of his Yak you will see the sticker with the kidd "pissing" 10 Li-Po. I wanted to know if someone have more information about his configuration (model weight, capacity of batteries, etc.)and performance of his Yak.

Interesting to see that a Yak styled plane was competing and it could hold its own too! If he ran the 5230/18 then it would be 6S, its suppose to 3D a 4.5 kg plane so for a 5kg plane it will give very good uplines for sure.

F3A needs more power than 3D.. so if it's 'just right' for 3D on a 4.5kg plane, it will be too little on a 4.5kg pattern bird.
However, considering the results, it's obviously sufficient.

RE: Tournoi de Champagne
Generally, yes it does. Offcourse also depends on what you find viable for 3d performance 
If you have a plane that can do all 3D maneuvres, it can end up underpowered for F3A.
The reason for this is simple, in F3A you want to portray a single speed during your entire flight. So you want to fly the same speed vertical as level, at least, optically.
Suppose you're having reasonable winds (4bft) and are doing an inward looping from the top line, starting in the wind. Up to 3/4 you'll be fine, but you will need A LOT of power to get the looping nice and round and with the same speed for the last 1/4.
On electric planes:
150 Watt/kg - normal flight, not unlimited vertical, but it'll fly fine
300 Watt/kg - 3D capable
> 500 Watt/kg - F3A capable.
Most 3D flyers want more than 300 watt/kg, F3A pilots usually go for something like 600 watt/kg.
Take for instance the Plettenberg F3A engine, it can deliver 3.5kW of power. On a 5kg plane, that's 600Watt/kg..

RE: Tournoi de Champagne
Hezik ... okay I read you, 5kg plane trying to pull a huge loop up there where there is a strong wind unlike a 3D plane that is flying at eye level most of the time. You want that reserve power when you need it. I seen some F3A birds fly really well on about 500W/kg and they tell me they hardly push to full throttle for a P09. Thanks for the info ...
I have seen all the new F3A designs and they are suppose to be designed for P09 etc etc etc. How come a design like the YAK55 can come in 8th or is it a combination of a decent plane and a darn good pilot? Any takers?
