The plane looks awesome
, do you plan to paint it or cover it with iron on

ORIGINAL: ELIAS SOPEOGLOU
Friday evening I was even happier as I managed to do the first flight just before it became dark.The original impression is that the plane flys straight with only the slightest coupling of rud-ail mix that could also be managed by the rudder shape.Other than that no other mix is needed ! Snaps are crisp and precise and swept wing looks really nice and stalls clear and sraight.There is some work on the differectial to be done since it´s quite different to what I have flown so far.There is absolutely no pitch coupling at knife edge something that made me smile on my way back since I did all the work with the movable stab sys [sm=regular_smile.gif]
During the weekend I flew the plane with lipos thanks to my dear friend Alex (buka). With a final weight of 4500 ,the feeling of such a light plane made me even happier :-))
The only thing remaining now is good paint job and the plane is set ! Shortly will start on Nr2........

Elias.
Nice job, well done.
I flew about 100 flights last summer with 11s2p A123, worked quite well with a Hacker C50 12XL motor.
I made two packs, and recharged @20A in 12 minutes from mains supply, or @16A in 15-16 minutes using a small generator.
The charging was done directly on a Hysys 5020E power supply. (Max. 50V/20A)
This power supply works just like a normal CC/CV charger, no need for a separate charger. (NOT recommended for Lipos, but ok for A123)
I found that the 11s2p packs contained JUST enough energy for a P09 flight, with not much reserve.
(on A123 you don't need to limit your consumption to 80% of the pack capacity, but when it is empty, it really stops dead.)
What is the final weight of your wing panels?
Regards,
Magne

Hallo
Thanks for the comments !
The legs are ZN long legs ,the pants I made with my own mould out of carbon.
The wing spars are carbon prefabricated tubes 4mm outer.
About 123s I thing they are super cells but just not for competition ,who would like to fly a plane in a competition more than 500gr heavyer.
Magne your method is definately the way to go ,a guy over here charges them directly from a set of led batterys.
I just test flown them for trimming ,will definately go for the lipos and I´m about to decide what I´m getting.
Wing panels are not as light as I wanted them to be ,weight is 340gr less servo and paint .I guess 470gr all up weight with sevo(8401) and paint .Will be making a mould for the wings in the future ..
cheers
Elias

Hallo !
Finaly Imanaged to paint my plane ,it was quite adventurous since it was the first time for me to use water based acrylic car paint ,quite furstrating at times when paper tape soaked in moisture got saged (you can imagine at wich part of the plane !) anyways the result came quite ok ,maybe a bit heavyer now (havent weighted yet) but I really dont mind...
so here it is ..

Elias,
absolutely fantastic! Bar none, this is the best scratch project I've ever seen. From inception to completion a real tour de force.
Bravo!
Now, you'll just have to find a way to allow the rest of us to enjoy the fruits of your considerable labour... any plans to kit the model?

Hi Elias,
This is a very nice paint scheme.
I hope that the flying qualities are up to your expectations.
We now await your report of flight tests.
Anyway, thank you for sharing this experience with us.

RE: NEUTRINO - NEW F3A PROJECT FROM GREECE
Thank you all for the nice comments !
Sorry but there are no plans for kiting the plane ,I would never find the time ,someone else would have to do it and it would need a very reliable and good manufacturer for me to trust my moulds !
The T-can ,i had some rolling issues ,kind of barrel like ,they completely dissapeared when i removed the can ,i bet it has to do with incidence ,I think I´ll play with that after the WC .now the rolls are axial and precise ,I really love how this plane handles ,knife has no coupling at all and snaps are crisp and clean (I like the violent ones not the lazy ones).There is a slight pitch to the canopy on uplines and downlines ,there is absolutely no yaw in uplines regardless of speed ,right thrust is right on and it is only about 1deg ! Plane can fly pretty fast if needed in high wind conditions and I´m about to recieve my competition jeti90(currently using the simple) for setting my brake on downlines.
will be posting shots of inside setup soon..
Thanks egain for all the nice comments !

Hi Elias,This is one of the coolest F3A build i have seen, please do post some videos of the plane i am sure many of them would love to see it..Regards,Highfly

any wood kit designers have any comments? not trying to be a smart a^%, just asking.

I'm with everybody else, Ithink it's some awesome work. It's different. What IDOreally like is the nomex construction. There are only a handful of people that can do nomex and do it right. When it's done properly it's as good as it gets for composite fuses. The stiffness approaches wood planes. The key is the weight. Looks like Elias nailed it.
Ilove the color scheme too!

RE: NEUTRINO - NEW F3A PROJECT FROM GREECE
Superb job!!!!, from the design to the reality of flying, most people dream about doing a project like this, but a the level you accomplished it, I think it will be difficult to see it again if it is not from you again.
Congratulations Elias, you really are a master craftsman.
