Gliders > Slope Soaring
Wasabi Eco - Building Thread
Fred:
Well, after around 10 hours of really hard work , a few servos, battery and so on, it's finally time to fly the beast at your favourite slope !
Yeah, that's wood ! ;)
And the flying ?
Well, see flight number 3 and 4 by yourself ! :)
http://www.gliderireland.net/images/videos/wasabieco.wmv (18Mo for 3.40mins)
Not the best day to try the glider, but the machine managed to fly nicely !
As noticed by Francois, and as you can certainly see, I flew without snap flaps and camber. Even if that was programmed on my radio, I have to admit that I did not used the mixes :o
My C of G was a bit too much forward (89mm). And the machine is tough ! I had a few "landings" inverted (wayyyy too low/slow :p ) or on the belly after snap rolls or when the second loop in a row was a bit of a challenge :p but not a single scratch on the glider :)
I'll make another video on a better day with snapflaps and camber.
I have never tried the Wasabi before flying the WazEco, so I can't really compare, but what I've liked is the really sharp and precise response of all the moving surfaces whatever the speed. Even at low speed, almost stopped in the air, you can turn your roll very precisely. The speed range is quiet impressive for the size of the machine, even, in my case, with 0 camber all the time (light ? )
Well, the only limitation for the machine will be the pilot really...
Enjoy the video, and stay tuned for more ! (Thanks to Fernando for holding the camera ! :D )

Fred:
Oh yeah, bought a scale yesterday ! First time in my modeler's life I have one !
So, the WazEco weight RTF is 1050g, and went down yesterday to 1030g !
Pretty light, without even trying to save weight during the building process... You can't beat wood ! :mrgreen:
Fred:
Alright so... After our last outing, and the Wazeco laugh, I decided it was finally time to remove the fingers and do the set of wings I have for a few months now in my garage for it !
Wings are the same geometry as the Wasabi/Wazeco one, but changed the profile for the Sb96v at the root, going to a Sb96vs at the tip. Plan is to still have a fully aerobatic machine, but a machine that actually fly in poor lift conditions.
Foam cores were cutted by Joe (thanks :D ) and sheeting is made of 1mm balsa to keep it light. No spars etc etc, useless at that size, but the wings will have live hinges.
The second wing is drying right now
Fred:
Might be better with a few photos ! :oops:
I pass the balsa cutting etc etc, and here is the foam core with the tape for the live hinge.
Then, everything is bagged... I always put some cling film between the wood and the foam cores. Nothing stick to it... Just in case :roll:
Once dry, remove evrything from the bag, remove the cling film, and sand everything smooth, time to do the hinges.
Small cut on top (1mm wide), and a bigger one at the bottom, in a flat V shape, et voila !
And gluing of the TE
.... Well, nothing very difficult here !
Now, servos are in, TE sanded, and incidence pins glued... Covering tonight, and job done !
All in all, without the epoxy curing time, 2 hours spent on the wings to have them ready to cover :D
More photos once dne :D
Happy Days:
Fred, you said you put some cling film between the wood and the foam cores. I assume when you say “wood” you mean the balsa sheet? In which case surely you would want the wood to stick to the foam core :?: ……………..wouldn’t you???
(Or am I just being exceptionally stupid today :oops: )
