Got a chance to fly my original (less wing tips) today for a few minutes. I think I like mine better with the fins. There was a bit of breeze, maybe 10 mph but not bad. It seemed to get blown around quite allot and wasn't as "stable".

I just glued some new ones on, will fly with again in a few days to see the result.

Looking good Carl. I used a similar bay cut out with the thin plastic on the bottom. It is amazingly strong.

To cover the top of the bay or not? I'd say don't worry about it unless you are looking for the most speed or longest flight times as I think it would reduce drag a bit. Nice thing about open is keeps the parts cooler.

Weather sucks this part of the world too. We have a 4 day weekend coming up (Thanksgiving on Thursday) so hopefully will get a chance to fly some and test out my new tips!

Had great weather yesterday so go a chance to get out and fly.

Flew the KESL with the wing tips back on and like it much better. I had some coroplast tips laying on my bench from a previous build so cut them down a little and used them. It is much more stable and I think it even floats a bit better. Lots of fun. Stuck my "key chain camera" on the nose for a few minutes, got some decent video. Will post if anyone is interested.

hi rdjay, i would really like to watch your video, sadly i am still waiting to maiden the 36" kesel, still not had a break in the weather, but fingers crossed some time soon it will ease up, and i have also used the keychain camera on the wng, i just velcroed it on a slightly downwards angle, and it seemed to get good video, i also tried putting it on the back of the kesel, i have put the back view on here

Nick, I just taped it on the nose with some strapping tape, quick and easy.

Doggit, like the rear video, good flying! What comes down over about the top 1/4 of the frame towards the end?

Something strange happened to my KESL video from Friday. Windows won't play it (some lame error) but it plays fine with Quick Time. I took another yesterday in less perfect (bit windy) weather, it seems to be working fine. I'll get it uploaded to Vimeo tomorrow and post a link.

Hey guys, I took the wing tips off my KESL. I have to tell you I do not like them off . It seems like my rolls are much slower now. The wing is also pitch sensitive (maybe I should redo the CG?) It also seems like I spend a lot of time correcting for the wing twisting left and right in the wind which is weird to do with only elevons and no rudder. I also notice that the wing will rock and twist coming out of a loop or roll without the wing tips.

One good thing about tipless though: to me it does seem like the wing glides better. It's also cool to see it flying without the wing tips too, it's weird to see something fly without any vertical surfaces.

I would definitely not recommend a first time wing flier to skip the wing tips on the KESL.

Meistertek,

Congrats on the wing...the cool factor w/o wingtips is a plus, but you are correct in that thay add to total performance. You mentioned several posts back about my motor being forward.... and I was wondering what your thoughts were? My KESL2 is in the final stages and it will be alot cleaner than #1...before I go any further I would appreciate your input on this. RDJay I"m doing some of the same stuff you to bury servos,etc but also trying to come up with a cockpit.

Anyway things are moving a little slowly right now, had some shoulder surgery done 8 days ago, and just can't seem to get the right arm to be normal yet.... So everybody keep the posts coming.... I'm living through them at the moment...

Nick

hey RDjay, glad you liked the rear video, and the thing that appears near the end was just one of the wires from the motor, i just taped them down, but the tape came unstuck and the wire moved, well i am still waiting for this crappy uk weather to break, so i can try my 36",

meistertek, so you didnt like the tipless wing, maybe if i percivere with the tips on i may get use to it, and on my 36" kesel i am trying the similar cut on the end of the wings as the assissin not sure how its going to go, as i said above the weather is wet and windy, so still not maidened, hopefuly i can maiden it at the weekend and get some video

Yep, I'm sold the tips help. Here's a video from the nose with the key chain camera.

KESL Onboad (5 min 43 sec)


Wind was blowing (5-10mph I'd guess) but the wing handled it fine although a little "bumpy".

I'm going to experiment with the focus on the camera, seems it could be a bit sharper.

hey RDjay thats an amazing video, and i am still dizzy i liked your low passes, and thats a nice big flying area you have, it has made me want to get my 36er out now, and your camera seems to have a good focus on it, and you got some high flights on the kesel, cant wait for some more of your videos

Thanks, the one low pass about 2/3 through (right before the fade) almost ran into myself! Focusing on the wing and forgot it was headed right at my nose! I ducked out of the way and ended up skidding across the track.

That school field is pretty big and real and close to home. Bigger fields farther away, wish the video from last Friday worked, it was at a huge area, nicer weather, lots better, oh well. Will do more as time/weather permits.

And Nick, get that arm healed up and get out flying!

Hey Nick, I would think that moving the motor forward would be fine if it's required to balance at the recommended CG of 8.5" Doggit however said he did not like the performance of his wing with the motor in the middle, so maybe there is a point where the motor would be too far forward. All my KESLs so far have the motor in the stock plan location except the ducted fan KESL that had the motor pretty close to the CG.

Hope your are heals up quickly man!
