Snowfox 20 canard for 6400


20" ws canard pusher based on the firefox. i watched 1 flying but, as i could not get 1, i decided to design 1 with approximate proportions, and larger.
it is made of 5mm depron for wing, canard and fuselage keel, 3mm for top and side fuse, 1mm for elevons. 1mm cf rods on wing, canard and fuse.
1015 motor with kenway gear box, gws 6/3 prop.
6400 brick, 240mah single hyperion cell.
there are pictures in my blog

Well done and it seems to fly well. Flying with nose up tho - under powered?

Looks good in the air and NOT flying like a rocket as many small models do

thanks. it is the prototype, and is larger than the firefox, so i was not sure of the cg. i got some advice but it started very tail heavy and sometimes suddenly fell as a leaf, so i began adding weight to the nose until began to fly nicely. still, after the video, i added more weight to the nose, as it still was showing symptoms of tail heaviness. now it weighs 81 grams with all the ballast i had to add for balance, but the 1015 geared seems to handle it well, at about 75% throttle. and am making a new 1 taking in consideration where it likes the cg to be, so i will distribute the components as to not to need extra weight for balance. the idea is to take advantage of the canard's ability to fly slower than conventionals, as i like planes as slow as possible. so far, my snowflake beats all, but i have hopes that these canards will do even slower. keep in touch and we''ll see.

thanks, gambler. i am using the step to add stability and slow it down too, for i don't want it for breaking any speed record but the opposite.
as i said before, i watched 1 firefox flying and was amazed by how slow it flies, but was unable to get a kit, so i decided to make 1 based on that 1, just larger, and the proportions are by eye only, making adjustments to match the materials at hand. at the beginning the cg was too far aft and it used to fall like a leaf unexpectedly until i began to add weight to the nose. see previous post.
am working on another to replace it, with a better distribution of components and a longer nose moment-and some changes in structure to make it lighter.

Thanx Phil for updating me. Yep, I do like flying at scale speed too hence your model caught my eye. Falling out of sky is a sure indicator of tip stall so obviously bringing CofG forward has improved its flying. This hobby is very scientific as you know and you can't defy science without paying the penalty

Please keep us updated.

I'm off to testing OD 52" BAE Hawk - as used by the famous RAF Red Arrows display team.

thanks for your comments. well, it was not tip stall: it was the whole wing! it just stopped in midair and began to do the leave's fall. no penetration at all. and if a canard does that, it means that the canard is not stalling first, which is what canards are known for. so, when this happens means that it is tail heavy. very tail heavy.
regards

Sorry Phil but I'm having difficulty in down loading the vid. Is it possible to have it in wmv. file or via YouTube?

Thanks
