Komet 163B

I'll a little surprised that we don't have a half of dozen of these posted here in the Nurflügel forum.

I started this one some years back before I was side-tracked down Horten alley. Just starting to hack away at this one again. Maybe can get the main skid to work this time. I'll put the skid latch on a direct servo this time rather than string driven by the flap servo.....what was I thinking.

Kent,
I am quite envious of your wonderful projects such as this ME163 with beautiful ribs showing through but also of your slope!

Enjoy those ribs while you can, this one is heading for a scale-like paint job. Not really my thing, but that was the original idea so in this sitting I'll try to make it look like a plane, at least from 30' away.

This coastal slope site is really a blessing. The only complaint is that it is flyable so many days of the year, that there is a very limited building season. But the building season is here, at least for the next few weeks anyway.

Toying around with the video editing program and some landings from the test flying in 2010.

Geese Kent, that one sure does fly nice. I'd love to build one, only it is my misfortune that I am not cursed with such a flying site. One would think that living in the hills as I do, that there would be all kinds of sites to slope from, but noooooo. I have noticed one place, almost always see the birds soaring the ridge. Nice road running up the side to the top. Of course there is also a big chain link fence with locked gate and big no trespassing signs posted. Think it's owned by the gas company. Maybe some day i might stumble on a good site and things will change, but for now it's thermal or power. No real sloping for this kid.

Barely flies is more like it, but with the massive lift available in Spring, even this plump little wing looks almost snappy. Elevons, flaps and rudder with wing slots in front of the slotted elevons make for great control. In the last video, winds might have been 25mph with a 100' cliff.

This was the project where I learned about fuse drag. I knew that a 6" diameter fuse on a small wing would create SOME drag but it's "streamlined" so how bad could it be?

Pretty bad actually....it's like flying with the brakes on. Maybe there is a ballast box in this one's future. Having a model of rocket powered Komet that flies slow is...well....counter-intuitive. Still fun though.

Over the years we have investigated lots of potential slope sites. After being escorted out of Fort Ord by armed MPs kinda changes your perspective. Access is problematic. It's easier to seek forgiveness, than permission. Nowadays I fly at State Parks.

I like to line up my landings so I can see right down the wing to see the angle of attack. I could see this one really good!

This one left a welt.

Kent, did you build from a found plan or is your 163 OD? I have one on the table right now that I am building from this plan I found on the Outerzone page.

Going to use a HET ducted fan as we are slope deprived here in Vancouver even though there are mountains every which way you look.

BTW, did your Komet leave a bruise?

Hi TD. This one was from scratch or to be exact, a Rhino 3D model. There is a link in the first post. Looks like your wing has a symmetrical airfoil. That coupled with a motor, should give stunning results. If I were ever to motorize one of my gliders, it would be the Komet.

Luckily my leg was hit by a balsa leading edge backed up 1/64" plywood wing sheeting, so the wing crumbled right away. I don't recall a bruise, but it was sore for a day.

Which brings us up to date. The crash was the last time this one was flown. Wing repair is largely done and now am having another go at the wing fillet before covering in Koverall and paint.

Just out of curiosity I weighed mine.750g empty,49" span.
Fully symmetrical,just a touch of reflex.
Some pics #70 in the show your Nurflugal thread.

750gr....yikes, that's light. I trust that is the bare airframe only. Is this one still flying?

Mine is built for the slopes and is somewhat more "robust" (read heavy). Soon to be heavier, I'll break out the body filler today. Who knows, there may be a ballast box soon. Last time I checked the story was:

scale 1:6
AR 4.2
span 45.5" (1.26m)
area 590 sq. in.
weight 88oz (2495gr)
wing loading 21.48 oz/s.f. (64.71gr/dm)

I don't do much scale building these days. I do have a small epower Me163.

My favorite scale candidate of all time is the DeHavilland Swallow.

I think that in terms of every feature, it's just a beautiful design. - Herk

I had 2 of these, a 1:6 and a 1:5 scale one. They both flew beautifully. One had JeCentral Bee and the other a Merlin 90. The 1:5 scale one was a converted adapted Mick Reeves Venom fuselage and the other was a very old kit. One of my favourites too.

From what I've read,after they let Lippisch go to the US,DH used his 163 wing design on the Swallow.
# Kent,it developed a warp which I never managed to cure.Wings1/16 sheet,fuse 1/8 plank.Both sanded to about half thickness!
