Thanks! Yeah, I think gliders without throwing blade have lower drag and better wing balance. And I still get good altitude, so it's not a disadvantage. It's a good idea for smaller gliders like this one. If it were a big 1.5 meter, it would need a throwing blade.
Thanks! Yeah I’m definitely improving the more I practice. Also my gliders are getting better and better with the lift/drag ratio which definitely helps them climb higher.
100% on last time. Great to see. When you said red raven it reminded me of the hobby king raven(900mm wing version). It is very similar in design and weight to yours.
Yeah I used to have that one. Pretty nice flier. Actually based this one off of that one in that I used the same airfoil and leading edge construction.
Very nice, it fly great right now It make me really impatient to build mine. For the moment, I only worked on design, and I have build a small (1/3 size) free-flight version for testing it. Stay safe and take care of your family
Less twitchy but it flies fast (probably due to the increased weight). I also noticed it tends to turn left. Overcompensation of the initial right turn or is your left wing slightly heavier? Did you find a way to level out better after launch? Anyway, it’s a splendid achievement! Congratulations!
Yes the high cruising speed is an issue. It is probably easily overshooting the optimum L/D speed. I will try to decrease the weight by about 10 grams and see if that helps things. Constant left turn is still a mystery to me. I think it may be due to the right wing airfoil having higher upper surface camber. Wing weights are equal, and there is no warpage, so that is my best guess. If the upper surface camber is indeed unequal between both wings, that is a result of human error and I will have to work on more precisely cutting the airfoils. I think I will have to increase down-elevator deflection to improve level-out performance.
Copterdude I’m not convinced the upper camber is the culprit. A difference in wing incidence or dihedral angle would be my first choice but I guess you checked those. Maybe the leveling problem at the top of the launch also has something to do with wing incidence.
@@kaminajo Yeah my methods of checking wing incidence might not be very precise. I will have to work on some better setups for accurately measuring the various angles of the airframe.
More dihedral is what you need IMHO. Nice model.
Certainly. it taught me a valuable lesson.
Awesome flights! I like that You are not use throwing blade for Your DLGs. You can launch it very high! My favourite launch at 2:52.

Looks like you got it flying great! Nice discuss technique too!
Thanks! :)
EXCELLENT!!! I'd say you nailed it this time.
Thanks! I agree. :)
Always impressed with your technique, you get great altitude with your launch.

Looks like your mods worked. Job well done sir!
Yep. Thanks! :)

Thank you! Glad you like it.
Yes, building a small-scale model is always a good idea. Hope your glider works out well. Stay safe. Cheers!
Looking good!
Thanks!

Great flight!
Even with acrobatics!
Thank you! Yeah this one’s very nimble.
