Hi,

Sebart has a new 2M F3A machine in the pipe line, some photos of the new plane that is named PrometheuS is here:

http://www.massimoselva.com/wordpress/?p=2305
http://www.f3a.fr/nouveau/sebart-prometheus-t4612.html

- Larger canaliser/top wing (then MythoS Pro) it seems, and also it has slight dehedral.
- Also a small low wing, with slight anhedral.
- Small "cheeks" in nose cowl that extends to wing leading edge.
- Rather high fuselage.
- Seems the top small wing is separate from canopy unit, and the small low wing is removable from fuselage.

Lots of wings... maybe not so practical for transportation but if it flies better why not...

I do not know when it will be released.

I recall seeing pictures of the smaller "wings" being tested on a Sebart HeraS biplane.

I assume this will be an Oxai plane designed by Sebart?

And when you say " lots of wings" , this immediately comes to mind.

Hi,
I hope not the new Sebart PrometheuS will be produced by Oaxi in one sense: just for the fact that all 2M F3A planes produced by Oxai is very expensive (although very high quality). Personally I would prefer it is made in same way as MythoS Pro so the price will be in reach for people with more normal seize wallet. I would not dream to spend as much money on a new 2M F3A plane as a plane cost made by Oaxi since I prefer to keep this hobby at reasonable cost levels. To spend maybe US $5.500 up to almost $6000 on some Oaxi plane is just to much (for me). But it is nice they are available for those that want them and have money to spend.

The current MythoS has dihedral on the Canilizer but that one almost seems flat, not loving the rounded shape either! This one doesn't inspire me, the lines just aren't as attractive...

Oxai has out-priced the market IMO...

I'm not really an F3A guy but enjoy the style and do wish to build and fly something in this realm sometime in the next year. IMO it looks to me somebody need a lessen in designing an airplane. It's no longer a mono wing plane but it's not a biplane nor a triplane. It does have only a single set of empenage though. I'm thoroughly about this one

I think this one has carried the "I'll just stick a little wing on here" to make it fly "better" to far.

This reminds me of the anhedral tails on late '70's-early '80's pattern planes. They were "in". And soon they were out. Now I see a few 2M planes with anhedral stabs. How long will this last?...How long before something replaces canalizers?

Hi,
The canalizers regardless at top or at low position or on both places is there to help aid in for example better knife edge and better rudder effectivness because the canalizer direct the airstream more along the rear of fuselage and tail making it more effective. That is my understanding.

Some may think one or two small canalizer improve appearance of a plane but I think they make a plane uglier (despite I have a plane myself with canalizer, MythoS Pro) and they can make transportation/assembly more difficult and You get hangar rash easier I think.

I wish someone could make a beautiful F3A plane without canalizer that flies as good that a plane that has that. I suppose if it was to appear an F3A World Champion that use a monoplane without canalizer (and that flies even better then planes with canalizer), maybe the trend would be broken?

It will be interesting to see how well Bryan Hebert new plane Allure (no canalizer) will place at competitions. I have no opinion on the appearance of that plane but at least it has no canalizer(s).
http://www.ckaero.net/products.php
http://www.rcuniverse.com/forum/elec...an-hebert.html

The ideal in my opionion would be a very nice looking plane (subjective of course) with minimal mixes needed and no canalizers or other "things" hanging on fuselage or wing to correct other problems (and no contra to keep cost down).
And I kind of miss retracts on our F3A planes... I suppose it never will come back in F3A again in competition planes or...?

Bryan Hebert's Alferma Bipe prototype has retracts, although he said the production model will not.
Too bad, looks nice with wheels retracted.

Keep increasing the size of a canalyzer and you end up with a biplane

AFAIK, the Galactik has one of the largest canalyzers in F3A today

Hi,
Last competiition in F3A for this season here in Sweden was held this weekend at Linköping and I participated in the Advanced class (named "Nordic" class here here in our Nordic countries). It was two beauitful days with sunshine and light to moderate winds. In F3A class the winner was (as always) the present national champion Anders Johansson - congratulations to him. He won all 4 rounds.
In the Advanced class/Nordic the winner was... and same here the winner won all 4 rounds.

I'm pleased with the competition season, two wins and one second place.
I have about 250 flights total on my MythoS Pro this season now.
Zero maintenance on plane, motor or anything else in the plane during 250 flight - not bad.

Now I will take a little break from F3A flying, later in autumn I will fly with some of my other planes and also in winter try to build some F3A classic plane from the good old days (for me that is primarily from the 1970th). In winter I will also fly with my Wind S50E on skiis (and maybe my MythoS 125E on skiis also) that I think is very fun even if it is very cold out there. In clear winterdays with sun and calm winds... is very hard to beat - the sky is so clear, the light is so bright when snow and sunhine all over the place and the planes flies really good in cold dense air.
