canard w/ sweep forward wing for 6400


just watched flying a tiny (some 16"ws) epp foamie plane with 6400 components (brick, motor and gear box).
it did stunts and still could fly very slow. it is a kit that comes painted black, with some red trim. it uses just 2 servos connected to the main wing. front wing (stab?) is fixed.
it looks like a scale version of a full size experimental, but can't remember which 1 is it.
does anybody knows who makes it?
thanks

that's it!


thanks. that is the 1.
the 1 i saw has the 6400 brick and the 4site motor/gearbox, and a gws 5/3 prop and flies just great. it uses the 2 servos on the 6400 for elevons only and seems to be all that it needs.
thanks again.
great model. congratulations to the designer.

now and then...


thanks. seems that it started when the technology was not as advanced as is today. the 1 i saw uses lighter components and flies great. i think it does better than what there was available at the time.

I've flown the Super Jet which is the conventional wing version. Flies fast and slow. Very relaxing. Easy to fix. Long flight times. I'm on my second one now. Check HK for reviews.

thanks, MT. great advice.
at this time am trying to evaluate the swept forward wing-with canard. what i know is that a swept forward wing makes an airplane more maneurable-and that means unstable, too, but i saw a firefox (with swept forward wing and canard) flying seemly very stable and maneurable, although that could be just that the pilot is very good. that's why am trying to learn how i can do with that.
and am also trying to learn where it balances.
anybody?
regards

At this scale and weight and with flat wings I doubt there will be a big difference between forward and backward swept wings. Balance on the firefox is 2-3cm in front of the leading edge according to Metroidrc in the other thread.

i have to admit that, at the end of the day, the results may be the same.
still, maybe i will try both and see. but it takes lots of testing to be absolutely sure if really there is any difference.
thanks a lot for your comments.
and about balance: would it be measured from the tips? that he does not say.

I think it is measured from where the leading edge makes a V close to the body.

Felipe, this plane is a twist from ELF concept maybe some more scale is nice, the X-29 is a good subject.

that's where i would do it. thanks.

and about your plane (the super jet): where does it balance? measured from where?
thanks

Sounds like at the intersection between the center triangle and the main leading edge. So at that shallow "V" go back 2-3 cm and then do some test glides.
